The total amount of suffering per year in the natural world is beyond all decent contemplation. During the minute that it takes me to compose this sentence, thousands of animals are being eaten alive, many others are running for their lives, whimpering with fear, others are slowly being devoured from within by rasping parasites, thousands of all kinds are dying of starvation, thirst, and disease. It must be so. If there ever is a time of plenty, this very fact will automatically lead to an increase in the population until the natural state of starvation and misery is restored. In a universe of electrons and selfish genes, blind physical forces and genetic replication, some people are going to get hurt, other people are going to get lucky, and you won't find any rhyme or reason in it, nor any justice. The universe that we observe has precisely the properties we should expect if there is, at bottom, no design, no purpose, no evil, no good, nothing but pitiless indifference.
Richard Dawkins (River Out of Eden: A Darwinian View of Life)
If there's any interaction between genes and languages, it is often languages that influence genes, since linguistic differences between populations lessen the chance of genetic exchange between them.
Luigi Luca Cavalli-Sforza
Ariadne in the labyrinth. The most alive of worlds, human beings with the tenderest flesh, are made of marble. I strew devastation as I pass. I wander dead-eyed through cities and petrified populations.
Jean Genet (Our Lady of the Flowers)
Ask ten different scientists about the environment, population control, genetics and you'll get ten different answers, but there's one thing every scientist on the planet agrees on. Whether it happens in a hundred years or a thousand years or a million years, eventually our Sun will grow cold and go out. When that happens, it won't just take us. It'll take Marilyn Monroe and Lao-Tzu, Einstein, Morobuto, Buddy Holly, Aristophanes .. and all of this .. all of this was for nothing unless we go to the stars.
J. Michael Straczynski
Every politician, clergyman, educator, or physician, in short, anyone dealing with human individuals, is bound to make grave mistakes if he ignores these two great truths of population zoology: (1) no two individuals are alike, and (2) both environment and genetic endowment make a contribution to nearly every trait.
Ernst W. Mayr
Those Who From Heaven To Earth Came". They landed on Earth, colonized it, mining the Earth for gold and other minerals, establishing a spaceport in what today is the Iraq-Iran area, and lived in a kind of idealistic society as a small colony. They returned when Earth was more populated and genetically interfered in our indigenous DNA to create a slave-race to work their mines, farms, and other enterprises in Sumeria, which was the so-called Cradle of Civilization in out-dated pre-1980s school history texts. They created Man, Homo Sapiens, through genetic manipulation with themselves and ape man Homo Erectus.
Zecharia Sitchin
A recent landmark global study in population genetics by a team of internationally reputed scientists (as reported in The History and Geography of Human Genes, by Luca CavalliSforza, Paolo Menozzi and Alberta Piazzo, Princeton University Press) reveals that the people who inhabited the Indian subcontinent, including Europe, concludes that all belong to one single race of Caucasian type. This confirms once again that there really is no racial difference between north Indians and south Indian Dravidians.
Stephen Knapp (The Aryan Invasion Theory: The Final Nail in its Coffin)
Prior to the genome revolution, I, like most others, had assumed that the big genetic clusters of populations we see today reflect the deep splits of the past. But in fact the big clusters today are themselves the result of mixtures of very different populations that existed earlier.
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
Behavioral genetics confirms that aggressive tendencies can be inherited, and that gives natural selection material to work with in shifting the average violent tendencies of a population.
Steven Pinker (The Better Angels of Our Nature: Why Violence Has Declined)
Not sleeping enough, which for a portion of the population is a voluntary choice, significantly modifies your gene transcriptome—that is, the very essence of you, or at least you as defined biologically by your DNA. Neglect sleep, and you are deciding to perform a genetic engineering manipulation on yourself each night, tampering with the nucleic alphabet that spells out your daily health story.
Matthew Walker (Why We Sleep: The New Science of Sleep and Dreams)
Genetics, accidents of birth or events in early childhood have left criminals' brains and bodies with measurable flaws predisposing them to committing assault, murder and other antisocial acts. .... Many offenders also have impairments in their autonomic nervous system, the system responsible for the edgy, nervous feeling that can come with emotional arousal. This leads to a fearless, risk-taking personality, perhaps to compensate for chronic under-arousal. Many convicted criminals, like the Unabomber, have slow heartbeats. It also gives them lower heart rates, which explains why heart rate is such a good predictor of criminal tendencies. The Unabomber, Ted Kaczynski, for example, had a resting heart rate of just 54 beats per minute, which put him in the bottom 3 per cent of the population.
Adrian Raine
Professor J. B. S. Haldane was one of the most celebrated scientists in Britain. A pioneering and broad-ranging thinker, he developed a mathematical theory of population genetics, predicted that hydrogen-producing windmills would replace fossil fuel, explained nuclear fission, and suffered a perforated eardrum while testing a homemade decompression chamber: “Although one is somewhat deaf,” he wrote, “one can blow tobacco smoke out of the ear in question, which is a social accomplishment.
Ben Macintyre (Operation Mincemeat: How a Dead Man and a Bizarre Plan Fooled the Nazis and Assured an Allied Victory)
three conclusions: (1) at least weak forms of superintelligence are achievable by means of biotechnological enhancements; (2) the feasibility of cognitively enhanced humans adds to the plausibility that advanced forms of machine intelligence are feasible—because even if we were fundamentally unable to create machine intelligence (which there is no reason to suppose), machine intelligence might still be within reach of cognitively enhanced humans; and (3) when we consider scenarios stretching significantly into the second half of this century and beyond, we must take into account the probable emergence of a generation of genetically enhanced populations—voters, inventors, scientists—with the magnitude of enhancement escalating rapidly over subsequent decades.
Nick Bostrom (Superintelligence: Paths, Dangers, Strategies)
Culture can be loosely defined as the body of non-genetic information which people pass from generation to generation.
Paul R. Ehrlich (The Population Bomb)
Our recent divergence from a small population explains another important fact, one that every human ought to know: we are a genetically homogenous species.
Daniel E. Lieberman (The Story of the Human Body: Evolution, Health, and Disease)
Population genetics calculations suggest that in 5 million years (one million years longer than the alleged time between Ambulocetus and Rodhocetus), animals with generation lines of about ten years (typical of whales) could substitute no more than about 1,700 mutations.6 This is not nearly enough to generate the new information that whales need for aquatic life, even assuming that all the hypothetical information-adding mutations required for this could somehow arise. (And as shown in chapter 9, real science shows that this cannot occur.)
Jonathan Sarfati (Refuting Evolution: A Response to the National Academy of Science s' Teaching About Evolution and the Nature of Science)
I think knowledge is a blessing, not a curse. This is especially true in the case of genetic knowledge. To understand the molecular nature of cancer for the first time, to diagnose and prevent Alzheimer’s disease, to discover the secrets of human history, to reconstruct the organisms that populated the pre-Cambrian seas – these seem to me to be immense blessings.
Matt Ridley (Genome: The Autobiography of a Species in 23 Chapters)
Over generations, the gene pool of the first farmers became increasingly dominated by individuals who could drink beer on a regular basis. Most of the world’s population today is made up of descendants of those early beer drinkers, and we have largely inherited their genetic tolerance for alcohol.
Steven Johnson (The Ghost Map: The Story of London's Most Terrifying Epidemic--and How It Changed Science, Cities, and the Modern World)
Because of their sublime genes, the orphans were all incredible specimens and often referred to by their creator, Doctor Pedemont, and by Naylor, Kentbridge and the rest of their Omega masters, as post-humans. Their DNA was different to anyone else’s and by their teens they were superior in many ways to the rest of the population, being smarter, faster, stronger and more adaptable.
James Morcan (The Ninth Orphan (The Orphan Trilogy, #1))
The human population is too large, and the earth too small, to sustain us in the ways our ancestors lived. Most of the land that is good for farming is already being farmed. Yet 80 million more humans are being added to the population each year. The challenge of the coming decades is to limit the destructive effects of agriculture even as we continue to coax ever more food from the earth.
Nina V. Fedoroff (Mendel in the Kitchen: A Scientist's View of Genetically Modified Foods)
Perhaps various branches of genetically enhanced humans will populate different parts of the solar system and eventually diverge into separate species. And one can imagine that rivalries and even warfare may break out between different branches of the human race.
Michio Kaku (The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond Earth)
If you didn’t already know this, the sun is going to die. When I think about the future, I don’t think about inescapable ends. But even if we solve global warming and destroy nuclear bombs and control population, ultimately the human race will annihilate itself if we stay here. Eventually, inevitably, we will no longer be able to live on Earth: we have a giant fireball clock ticking down twilight by twilight. In many ways, I think mortality is more manageable when we consider our eternal components, our genetics and otherwise that carry on after us. Still, soon enough, the books we write and the plants we grow will freeze up and rot in the darkness. But maybe there’s hope. What the universe really boils down to is whether a planet evolves a life-form intelligent enough to create technology capable of transporting and sustaining that life-form off the planet before the sun in that planet’s solar system explodes. I have a limited set of comparative data points, but I’d estimate that we’re actually doing okay at this point. We already have (intelligent) life, technology, and (primitive) space travel. And we still have some time before our sun runs out of hydrogen and goes nuclear. Yet none of that matters unless we can develop a sustainable means of living and traveling in space. Maybe we can. What I’ve concluded is that if we do reach this point, we have crossed a remarkable threshold—and will emerge into the (rare?) evolutionary status of having outlived the very life source that created us. It’s natural selection on a Universal scale. “The Origin of the Aliens,” one could say; a survival of the fittest planets. Planets capable of evolving life intelligent enough to leave before the lights go out. I suppose that without a God, NASA is my anti-nihilism. Alone and on my laptop, these ideas can humble me into apathy.
Marina Keegan (The Opposite of Loneliness: Essays and Stories)
We do know that humans got hit hard by the Toba Super Volcano. We were on the brink of extinction. That caused what population geneticists call a ‘population bottleneck.’ Some researchers believe that this bottleneck caused a small group of humans to evolve, to survive through mutation. These mutations could have led to humanity’s exponential explosion in intelligence. There’s genetic evidence for it. We know that every human being on the planet is directly descended from one man who lived in Africa around sixty thousand years ago—a person we geneticists call Y-Chromosomal Adam. In fact, everyone outside of Africa is descended from a small band of humans, maybe as few as one hundred, that left Africa about 50,000 years ago. Essentially, we’re all members of a small tribe that walked out of Africa after Toba and took over the planet. That tribe was significantly more intelligent than any other hominids in history.
A.G. Riddle (The Atlantis Gene (The Origin Mystery, #1))
The motto here is that sometimes the apparently inferior choice has a better upgrade path: Evolution can’t know this, and we aren’t particularly good at recognizing it ourselves. On the genetic level, it translates as follows: Natural selection may solve the same problems differently in different populations, and what appears to be the most elegant solution at the time may not in fact turn out to be the one that works best in the long run. The seemingly inferior choice
Gregory Cochran (The 10,000 Year Explosion: How Civilization Accelerated Human Evolution)
You are a species that does not question authority. You are complacent, fearful, and submissive. These genetic traits are the engine that have kept your corrupt economic system running for so long. We assure you, a new economic system will emerge as soon as the old one no longer resonates with the general population.
James Carwin (Pleiadian Prophecy 2020: The New Golden Age)
For many Westerners, “it’s natural” seems to mean “it’s good.” This view is wrong and comes from shopping in supermarkets and living in landscaped environments. Plants evolved toxins to deter animals, fungi, and bacteria from eating them. The list of “natural” foods that need processing to detoxify them goes on and on. Early potatoes were toxic, and the Andean peoples ate clay to neutralize the toxin. Even beans can be toxic without processing. In California, many hunter-gatherer populations relied on acorns, which, similar to manioc, require a labor intensive, multiday leaching process. Many small-scale societies have similarly exploited hardy, tropical plants called cycads for food. But cycads contain a nerve toxin. If not properly processed, they can cause neurological symptoms, paralysis, and death. Numerous societies, including hunter-gatherers, have culturally evolved an immense range of detoxification techniques for cycads. By contrast with our species, other animals have far superior abilities to detoxify plants. Humans, however, lost these genetic adaptations and evolved a dependence on cultural know-how, just to eat.
Joseph Henrich (The Secret of Our Success: How Culture Is Driving Human Evolution, Domesticating Our Species, and Making Us Smarter)
The combined effects of mutation, natural selection and the random process of genetic drift cause changes in the composition of a population. Over a sufficiently long period of time, these cumulative effects alter the population’s genetic make-up, and can thus greatly change the species’ characteristics from those of its ancestors.
Brian Charlesworth (Evolution: A Very Short Introduction (Very Short Introductions))
What really happens in the Western countries that adopt feminism and individualism is not the complete end of the human race, but rather, the relative demographic decline of the native populations of liberal democracies. The individual irrationality of the self-sacrificial parent to child relationship helps produce genetically suicidal birthrates.
Mitchell Heisman (Suicide Note)
Before we adopt US working practices, we should remind ourselves that the white American genetic make-up is exclusively drawn from the most restless, obsessive, zealous, neurotic and friendless 5% of the European population. The reason the Pilgrim Fathers were forced to leave these shores had little to do with religion — it was because nobody liked them.
Rory Sutherland (Rory Sutherland: The Wiki Man)
Since the 1980s, Attention Deficit Disorder (ADD) has been on the rise, not just among children, but now among the adult population as well. The sudden rise of adult ADD, while it may have genetic components, certainly receives a major boost from our kinetic, hyper-speed, information-bombarded society. Victims of adult ADD are likely to initiate more tasks and projects that they'll ever finish, get bored easily, seek thrills readily, have a propensity to be late while loathing having to wait, and not be averse to taking foolish risks.

It is curious that a genetic predisposition for homosexuality should persist in populations over the course of evolution, given that this group reproduces so much less.
D.F. Swaab (We Are Our Brains: A Neurobiography of the Brain, from the Womb to Alzheimer's)
if a Neanderthal Romeo and a Sapiens Juliet fell in love, they could not produce fertile children, because the genetic gulf separating the two populations was already unbridgeable.
Yuval Noah Harari (Sapiens: A Brief History of Humankind)
The only answer that I can give to this problem is based on Darwin’s principle of natural selection. The idea is that in any population of self-reproducing organisms, there will be variations in the genetic material and upbringing that different individuals have. These differences will mean that some individuals are better able than others to draw the right conclusions about the world around them and to act accordingly. These individuals will be more likely to survive and reproduce and so their pattern of behavior and thought will come to dominate. It

These numbers imply that the contribution of European American men to the genetic makeup of the present-day African American population is about four times that of European American women.

Genetic engineering and such products as Monsanto’s “Terminator” seeds, which cannot reproduce, could conceivably give that company proprietary control over the food crops. Glyphosate-based
Jim Marrs (Population Control: How Corporate Owners Are Killing Us)
Consider the genesis of a single-celled embryo produced by the fertilization of an egg by a sperm. The genetic material of this embryo comes from two sources: paternal genes (from sperm) and maternal genes (from eggs). But the cellular material of the embryo comes exclusively from the egg; the sperm is no more than a glorified delivery vehicle for male DNA—a genome equipped with a hyperactive tail. Aside from proteins, ribosomes, nutrients, and membranes, the egg also supplies the embryo with specialized structures called mitochondria. These mitochondria are the energy-producing factories of the cell; they are so anatomically discrete and so specialized in their function that cell biologists call them “organelles”—i.e., mini-organs resident within cells. Mitochondria, recall, carry a small, independent genome that resides within the mitochondrion itself—not in the cell’s nucleus, where the twenty-three pairs of chromosomes (and the 21,000-odd human genes) can be found. The exclusively female origin of all the mitochondria in an embryo has an important consequence. All humans—male or female—must have inherited their mitochondria from their mothers, who inherited their mitochondria from their mothers, and so forth, in an unbroken line of female ancestry stretching indefinitely into the past. (A woman also carries the mitochondrial genomes of all her future descendants in her cells; ironically, if there is such a thing as a “homunculus,” then it is exclusively female in origin—technically, a “femunculus”?) Now imagine an ancient tribe of two hundred women, each of whom bears one child. If the child happens to be a daughter, the woman dutifully passes her mitochondria to the next generation, and, through her daughter’s daughter, to a third generation. But if she has only a son and no daughter, the woman’s mitochondrial lineage wanders into a genetic blind alley and becomes extinct (since sperm do not pass their mitochondria to the embryo, sons cannot pass their mitochondrial genomes to their children). Over the course of the tribe’s evolution, tens of thousands of such mitochondrial lineages will land on lineal dead ends by chance, and be snuffed out. And here is the crux: if the founding population of a species is small enough, and if enough time has passed, the number of surviving maternal lineages will keep shrinking, and shrinking further, until only a few are left. If half of the two hundred women in our tribe have sons, and only sons, then one hundred mitochondrial lineages will dash against the glass pane of male-only heredity and vanish in the next generation. Another half will dead-end into male children in the second generation, and so forth. By the end of several generations, all the descendants of the tribe, male or female, might track their mitochondrial ancestry to just a few women. For modern humans, that number has reached one: each of us can trace our mitochondrial lineage to a single human female who existed in Africa about two hundred thousand years ago. She is the common mother of our species. We do not know what she looked like, although her closest modern-day relatives are women of the San tribe from Botswana or Namibia. I find the idea of such a founding mother endlessly mesmerizing. In human genetics, she is known by a beautiful name—Mitochondrial Eve.
Siddhartha Mukherjee (The Gene: An Intimate History)
As this book will show, objectively defined races simply do not exist. Even Arthur Mourant realized that fact nearly fifty years ago, when he wrote: 'Rather does a study of blood groups show a heterogeneity in the proudest nation and support the view that the races of the present day are but temporary integrations in the constant process of . . . mixing that marks the history of every living species.' The temptation to classify the human species into categories which have no objective basis is an inevitable but regrettable consequence of the gene frequency system when it is taken too far. For several years the study of human genetics got firmly bogged down in the intellectually pointless (and morally dangerous) morass of constructing ever more detailed classifications of human population groups.
Bryan Sykes (The Seven Daughters of Eve: The Science That Reveals Our Genetic Ancestry)
The three-fold increase in obesity in less that a quarter of a century cannot be the result of genetic change in the population. Rather, it is the result of increased availability and consumption of food, coupled with decreased physical activity.
David Bender (Nutrition: A Very Short Introduction (Very Short Introductions))
More daunting for those who hope for scientific and social progress, the genetic argument is easily used to justify all kinds of inequalities and injustices that are otherwise hard to defend. It serves a deeply conservative function: if a phenomenon like addiction is determined mostly by biological heredity, we are spared from having to look at how our social environment supports, or does not support, the parents of young children and at how social attitudes, prejudices, and policies burden, stress, and exclude certain segments of the population and thereby increase their propensity for addiction. The writer Louis Menand said it well in a New Yorker article: “It’s all in the genes”: an explanation for the way things are that does not threaten the way things are. Why should someone feel unhappy or engage in antisocial behavior when that person is living in the freest and most prosperous nation on earth? It can’t be the system! There must be a flaw in the wiring somewhere.
Gabor Maté (In the Realm of Hungry Ghosts: Close Encounters with Addiction)
the multidimensionality of human traits, the great variation that exists among individuals, and the extent to which hard work and upbringing can compensate for genetic endowment, the only sensible approach is to celebrate every person and every population as an extraordinary realization of our human genius and to give each person every chance to succeed, regardless of the particular average combination of genetic propensities he or she happens to display. For me, the natural response to the
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
In the United States both scholars and the general public have been conditioned to viewing human races as natural and separate divisions within the human species based on visible physical differences. With the vast expansion of scientific knowledge in this century, however, it has become clear that human populations are not unambiguous, clearly demarcated, biologically distinct groups. Evidence from the analysis of genetics (e.g. DNA) indicates that most physical variation, about 94%, lies within so-called racial groups. Conventional geographic "racial" groupings differ from one another only in about 6% of their genes. This means that there is greater variation within "racial" groups than between them. In neighboring populations there is much overlapping of genes and their phenotypic (physical) expressions. Throughout history whenever different groups have come into contact, they have interbred. The continued sharing of genetic materials has maintained all of humankind as a single species.
American Anthropological Association
As the political theorist Desmond King puts it, “One way or another, we are all going to be dragged into the regime of ‘gene management’ that will, in essence, be eugenic. It will all be in the name of individual health rather than for the overall fitness of the population, and the managers will be you and me, and our doctors and the state. Genetic change will be managed by the invisible hand of individual choice, but the overall result will be the same: a coordinate attempt to ‘improve’ the genes of the next generation on the way.

The experiment changed Sally’s life. In the following days she realised she has been through a ‘near-spiritual experience…what defined the experience was not feeling smarter or learning faster: the thing that made the earth drop out from under my feet was that for the first time in my life, everything in my head finally shut up…My brain without self-doubt was a revelation. There was suddenly this incredible silence in my head…I hope you can sympathise with me when I tell you that the thing I wanted most acutely for the weeks following my experience was to go back and strap on those electrodes. I also started to have a lot of questions. Who was I apart from the angry bitter gnomes that populate my mind and drive me to failure because I’m too scared to try? And where did those voices come from?’7 Some of those voices repeat society’s prejudices, some echo our personal history, and some articulate our genetic legacy. All of them together, says Sally, create an invisible story that shapes our conscious decisions in ways we seldom grasp. What would happen if we could rewrite our inner monologues, or even silence them completely on occasion? 8
Yuval Noah Harari (Homo Deus: A Brief History of Tomorrow)
As you study the trait in more environments, the heritability score will decrease. This is recognized by Bouchard: “These conclusions [derived from a behavior genetics study] can be generalized, of course only to new populations exposed to a range of environments similar to those studied.”31
Robert M. Sapolsky (Behave: The Biology of Humans at Our Best and Worst)
Although they have not left unmixed descendants, the Ancient North Eurasians have in fact been extraordinarily successful. If we put together all the genetic material that they have contributed to present-day populations, they account for literally hundreds of millions of genomes’ worth of people.
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
Nobel laureate Elizabeth Blackburn is more optimistic and says, "Every sign, including genetics, says there's some causality [between telomeres] and the nasty things that happen with aging." She notes that there is a direct link between the shortened telomeres and certain diseases. For example, if you have shortened telomeres- if your telomeres are in the bottom third of the population in terms of length-then your risk of cardiovascular disease is 40 percent greater. "Telomere shortening," she concludes, "seems to underlie the risks for the diseases that kill you...heart disease, diabetes, cancer, even Alzheimer's.
Michio Kaku (The Future of Humanity: Terraforming Mars, Interstellar Travel, Immortality and Our Destiny Beyond Earth)
Genetically speaking, individuals and groups are like clouds in the sky or dust- storms in the desert. They are temporary aggregations or federations. They are not stable through evolutionary time. Populations may last a long while, but they are constantly blending with other populations and so losing their identity.
Richard Dawkins (The Selfish Gene)
The desire to categorize humans along racial lines, and the impulse to superpose attributes such as intelligence (or criminality, creativity, or violence) on those lines, illustrates a general theme concerning genetics and categorization. Like the English novel, or the face, say, the human genome can be lumped and split in a million different ways. But whether to split or lump, to categorize or synthesize, is a choice. ... The narrower the definition of the heritable feature or the trait, the more likely we will find a genetic locus for that trait, and the more likely we will find that the trait will segregate within some human sub-population.
Siddhartha Mukherjee (The Gene: An Intimate History)
The case I’ve presented in this book suggests that humans are undergoing what biologists call a major transition. Such transitions occur when less complex forms of life combine in some way to give rise to more complex forms. Examples include the transition from independently replicating molecules to replicating packages called chromosomes or, the transition from different kinds of simple cells to more complex cells in which these once-distinct simple cell types came to perform critical functions and become entirely mutually interdependent, such as the nucleus and mitochondria in our own cells. Our species’ dependence on cumulative culture for survival, on living in cooperative groups, on alloparenting and a division of labor and information, and on our communicative repertoires mean that humans have begun to satisfy all the requirements for a major biological transition. Thus, we are literally the beginnings of a new kind of animal.1 By contrast, the wrong way to understand humans is to think that we are just a really smart, though somewhat less hairy, chimpanzee. This view is surprisingly common. Understanding how this major transition is occurring alters how we think about the origins of our species, about the reasons for our immense ecological success, and about the uniqueness of our place in nature. The insights generated alter our understandings of intelligence, faith, innovation, intergroup competition, cooperation, institutions, rituals, and the psychological differences between populations. Recognizing that we are a cultural species means that, even in the short run (when genes don’t have enough time to change), institutions, technologies, and languages are coevolving with psychological biases, cognitive abilities, emotional responses, and preferences. In the longer run, genes are evolving to adapt to these culturally constructed worlds, and this has been, and is now, the primary driver of human genetic evolution. Figure 17.1.
Joseph Henrich (The Secret of Our Success: How Culture Is Driving Human Evolution, Domesticating Our Species, and Making Us Smarter)
For evolution to be true, there would have been innumerable transitional forms between different types of creatures. Therefore, for every known fossil species, many more must have existed to connect it to its ancestors and descendents [sic]. This is yet another example of evolutionary conclusions coming before the evidence. Really, the claim is an implicit admission that large numbers of transitional forms are predicted, which heightens the difficulty for evolutionists, given how few there are that even they could begin to claim were candidates. . . . Evolutionists believe that mutation provides new information for selection. But no known mutation has ever increased genetic information, although there should be many examples observable today if mutation/selection were truly adequate to explain the goo-to-you theory. . . . Adaptation and natural selection are biological facts; amoeba-to-man evolution is not. Natural selection can only work on the genetic information present in a population of organisms--it cannot create new information. For example, since no known reptiles have genes for feathers, no amount of selection will produce a feathered reptile. Mutations in genes can only modify or eliminate existing structures, not create new ones. If in a certain environment a lizard survives better with smaller legs, or no legs, then varieties with this trait will be selected for. This might more accurately be called devolution, not evolution. . . . Note that even if such a mutation were ever discovered, evolutionists would still need to find hundreds more to give their theory the observational boost it desperately needs.

There was almost certainly a genetic contribution to Einstein’s dopaminergic traits. One of his two sons became an internationally recognized expert on hydraulic engineering. The other was diagnosed with schizophrenia at the age of twenty, and died in an asylum. Large population studies have also found a genetic component of a dopaminergic character. An Icelandic study that evaluated the genetic profile of over 86,000 people discovered that individuals who carried genes that placed them at greater risk for either schizophrenia or bipolar disorder were more likely to belong to a national society of actors, dancers, musicians, visual artists, or writers.

EVOLUTION RESTS ON three steps: (a) certain biological traits are inherited by genetic means; (b) mutations and gene recombination produce variation in those traits; (c) some of those variants confer more “fitness” than others. Given those conditions, over time the frequency of more “fit” gene variants increases in a population.

a result, the most efficient way for evolutionary forces to spread beneficial mutations has often been to invent mutations anew rather than to import them from other populations.44 The limited migration rates between some regions of Africa over the last few thousand years has resulted in what Ralph and Coop have described as a “tessellated” pattern of population structure in Africa. Tessellation is a mathematical term for a landscape of tiles—regions of genetic homogeneity demarcated by sharp boundaries—that is expected to form when the process of homogenization due to gene exchanges among neighbors competes with the process of generating new advantageous variations in each region.

Vaccinations are the application of evolutionary principles in action. If we can control the contact made between pathogen and lymphocyte populations, we can go a long way toward eliminating disease.108 It doesn’t require total annihilation but rather a control on population dynamics. Vaccines are the way we use selective cloning to keep a pathogenic population in a state of benign coexistence. The process is based on evolution, as pointed out by Nobel laureate Susumu Tonegawa: “Genes can mutate and recombine. These dynamic characteristics of genetic material are essential elements of evolution. Do they also play an important role during the development of a single multicellular organism? Our results strongly suggest that this is the case for the immune system.
Greg Graffin (Population Wars: A New Perspective on Competition and Coexistence)
Since the landmark 1972 paper by Gould and Eldredge, many studies have been done both with real populations and with mathematical simulations. The results explain why evolution appears both fast and slow: It is both fast and slow. Large populations tend to stay genetically about the same. Paleontologists say populations tend toward stasis. Small ones can diverge quickly into new species.
Bill Nye (Undeniable: Evolution and the Science of Creation)
Phylogeography began in the 1980s as a way to tell the evolutionary history of natural populations of animals and plants. It usually involves looking at a large number of “markers,” variable bits in the DNA of a species, for a lot of specimens from different parts of a species’ area of distribution. Phylogeographers can then use such rich information on the genetic make-up of a species to trace back its history.
Menno Schilthuizen (Darwin Comes to Town: How the Urban Jungle Drives Evolution)
So far, so good, but what about the man who rushes headlong into the fire to save a complete stranger? The stranger is probably not genetically related to the man who helps him, so this act must surely be truly unselfish and altruistic? The answer is Yes, but only by accident. The accident is caused by the rapid growth of human populations in the last few thousand years. Previously, for millions of years, man was tribal and any inborn urge to help his fellow-men would have meant automatically that he was helping gene-sharing relatives, even if only remote ones. There was no need for this urge to be selective, because there were no strangers around to create problems. But with the urban explosion, man rapidly found himself in huge communities, surrounded by strangers, and with no time for his genetic constitution to alter to fit the startlingly new circumstances. So his altruism inevitably spread to include all his new fellow-citizens, even though many of them may have been genetically quite unrelated to him. Politicians, exploiting this ancient urge, were easily able to spread the aid-system even further, to a national level called patriotism, so that men would go and die for their country as if it were their ancient tribe or their family.
Desmond Morris (Peoplewatching: The Desmond Morris Guide to Body Language)
The contamination of drinking water in dense urban settlements did not merely affect the number of V. cholerae circulating through the small intestines of mankind. It also greatly increased the lethality of the bacteria. This is an evolutionary principle that has long been observed in populations of disease-spreading microbes. Bacteria and viruses evolve at much faster rates than humans do, for several reasons. For one, bacterial life cycles are incredibly fast: a single bacterium can produce a million offspring in a matter of hours. Each new generation opens up new possibilities for genetic innovation, either by new combinations of existing genes or by random mutations. Human genetic change is several orders of magnitude slower; we have to go through a whole fifteen-year process of maturation before we can even think about passing our genes to a new generation.
Steven Johnson (The Ghost Map: The Story of London's Most Terrifying Epidemic--and How It Changed Science, Cities, and the Modern World)
Most people do not realize that, technically, Darwinism denies that species are real. The theory proposes that evolution proceeds through minor changes in an ever-continuous chain of individuals. What appear to be species are merely temporary groupings in the ever-shifting populations of evolving organisms, eddies in the genetic stream. (It is ironic that Darwin’s major work is called On the Origin of Species when in fact he denied the reality of species.)
Nancy R. Pearcey (Love Thy Body: Answering Hard Questions about Life and Sexuality)
Twin, family, and population studies have all conclusively shown that psychological traits are at least partly, and sometimes largely, heritable—that is, a sizable portion of the variation that we see in these traits across the population is attributable to genetic variation. However, as we have seen in the preceding chapters, the relationship between genes and traits is far from simple. The fact that a given trait is heritable seems to suggest that there must be genes for that trait. But phrasing it in that way is a serious conceptual trap. It implies that genes exist that are dedicated to that function—that there are genes for intelligence or sociability or visual perception. But this risks confusing the two meanings of the word gene: one, from the study of heredity, refers to genetic variants that affect a trait; the other, from molecular biology, refers to the stretches of DNA that encode proteins with various biochemical or cellular functions.
Kevin J. Mitchell
compiling the information on the number of years of education for over four hundred thousand people of European ancestry whose genomes have been surveyed in the course of various disease studies, Daniel Benjamin and colleagues identified seventy-four genetic variations each of which has overwhelming evidence of being more common in people with more years of education than in people with fewer years even after controlling for such possibly confounding factors as heterogeneity in the study population.25
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
When changes in one genetic trait are the source of selection for changes in a second, the rate of response in the latter depends in parts on the rate of change in the former, which, as a rule, is not fast. In comparison, if a cultural practice modifies selection acting on human genetic variation, then the greater the proportion of individuals in the population that exhibit the cultural trait, the stronger the selection on the gene. As a consequence, the rapid spread of a cultural practice often leads quickly to the maximally strong selection of the advantageous genetic variant, which rapidly increases in frequency. Cultural practices typically spread more quickly than genetic mutations, simply because cultural learning typically operates at faster rates than biological evolution. What does the speed with which a culturla trait spreads depend upon? Answer: the fidelity of cultural transmission. The very factor that is critical to the emergence of complex cumulative culture in humans is also a major determinant of evolutionary responses to that culture.
Kevin N. Laland (Darwin's Unfinished Symphony: How Culture Made the Human Mind)
Genetically speaking, individuals and groups are like clouds in the sky or dust-storms in the desert. They are temporary aggregations or federations. They are not stable through evolutionary time. Populations may last a long while, but they are constantly blending with other populations and so losing their identity. They are also subject to evolutionary change from within. A population is not a discrete enough entity to be a unit of natural selection, not stable and unitary enough to be ‘selected’ in preference to another population.

Elms are dying all over the place, it's Dutch elm disease. [...] It came from America on a load of logs, and it's a fungal disease. That makes it sound even more as if it might be possible to do something. The elms are all one elm, they are clones, that's why they are all succumbing. No natural resistance among the population, because no variation. Twins are clones, too. If you looked at an elm tree you'd never think it was part of all the others. You'd see an elm tree. Same when people look at me now: they see a person, not half a set of twins.
Jo Walton (Among Others)
it is easy to recognize an evolutionary process at work that has molded the human form for better survival in an arctic environment. Populations that live at high altitudes, like Tibetans, represent another adaptation to extreme environments; in this case, the changes in blood cell regulation are less visible but have been identified genetically. The adaptation of Jews to capitalism is another such evolutionary process, though harder to recognize because the niche to which Jews are adapted is one that has required a behavioral change, not a physical one.
Nicholas Wade (A Troublesome Inheritance: Genes, Race and Human History)
The propositions that accompany most of the chapters . . . are not as snappy as I would prefer—but there’s a reason for their caution and caveats. On certain important points, the clamor of genuine scientific dispute has abated and we don’t have to argue about them anymore. But to meet that claim requires me to state the propositions precisely. I am prepared to defend all of them as “things we don’t have to argue about anymore”—but exactly as I worded them, not as others may paraphrase them. Here they are: 1. Sex differences in personality are consistent worldwide and tend to widen in more gender-egalitarian cultures. 2. On average, females worldwide have advantages in verbal ability and social cognition while males have advantages in visuospatial abilities and the extremes of mathematical ability. 3. On average, women worldwide are more attracted to vocations centered on people and men to vocations centered on things. 4. Many sex differences in the brain are coordinate with sex differences in personality, abilities, and social behavior. 5. Human populations are genetically distinctive in ways that correspond to self-identified race and ethnicity. 6. Evolutionary selection pressure since humans left Africa has been extensive and mostly local. 7. Continental population differences in variants associated with personality, abilities, and social behavior are common. 8. The shared environment usually plays a minor role in explaining personality, abilities, and social behavior. 9. Class structure is importantly based on differences in abilities that have a substantial genetic component. 10. Outside interventions are inherently constrained in the effects they can have on personality, abilities, and social behavior.
Charles Murray (Human Diversity: The Biology of Gender, Race, and Class)
We cannot deny the existence of substantial average genetic differences across populations, not just in traits such as skin color, but also in bodily dimensions, the ability to efficiently digest starch or milk sugar, the ability to breathe easily at high altitudes, and susceptibility to particular diseases. These differences are just the beginning. I expect that the reason we don’t know about a much larger number of differences among human populations is that studies with adequate statistical power to detect them have not yet been carried out. For the great majority of traits,
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
The idea is that in any population of self-reproducing organisms, there will be variations in the genetic material and upbringing that different individuals have. These differences will mean that some individuals are better able than others to draw the right conclusions about the world around them and to act accordingly. These individuals will be more likely to survive and reproduce and so their pattern of behavior and thought will come to dominate. It has certainly been true in the past that what we call intelligence and scientific discovery have conveyed a survival advantage.
Stephen Hawking (A Brief History of Time)
Huxley’s Brave New World is set in an indefinitely distant future: it will not be possible for many years to say that Huxley’s apprehensions have not proved justified. It is unlikely that populations will undergo genetic and environmental manipulation in the exact way that Huxley foresaw: there will never be a fixed number of predetermined strata, from Alpha Plus to Epsilon Minus Semi-Morons. But as an Italian scientist prepares to clone humans, and as reproduction grows as divorced from sex as sex is from reproduction, it is increasingly hard to regard Huxley’s vision as entirely far-fetched.
Theodore Dalrymple (Our Culture, What's Left Of It)
I am suggesting here that organisms have a built-I capability of adapting to their environment. I am suggesting that to the extent that evolution occurs, it occurs at the level of the organism. This suggestion differs sharply from the thesis of the NDT, which holds that evolution occurs only at the level of the population. Organisms contain within themselves the information that enables them to develop a phenotype adaptive to a variety of environments. The adaptation can occur by a change in the genome through a genetic change triggered by the environment, or it can occur without any genetic change.

No product of agriculture is the slightest bit natural to an ecologist! You take a nice complex ecosystem, chop it into rectangles, clear it to the ground, and hammer it into perpetual early succession! You bust its sod, flatten it flat, and drench it with vast quantities of constant water! Then you populate it with uniform monocrops of profoundly damaged plants incapable of living on their own! Every food plant is a pathetic narrow specialist in one skill, inbred for thousands of years to a state of genetic idiocy! Those plants are so fragile, they had to domesticate humans just to take endless care of them!

Sexual-patriarchal relational systems overwhelm, from media glorifying sexual connection above other forms of intimacy and interaction, to medical, economic, and legal structures that automatically privilege sexual/domestic/romantic dyadic partnerships and genetic family bonds over other chosen platonic relationships and support systems. Oppressive social structures and micro-aggressive interpersonal interactions constantly grate on us, damaging our health and maybe even pushing us to seek care, but often available formal assistance is part of the same harmful system and populated by the same privileged persons.

Since the soon-to-be outnumber the living; since the living have greater impact on the unborn than ever before thanks to depletion of natural systems, atmospheric disruption, toxic residue, burgeoning technology, global markets, genetic engineering, and sheer population numbers; since our scientific and historic understandings now comfortably examine processes embracing eons; and now that our plan-ahead horizon has shrunk to five years or less—it would seem that a grave disconnect is in progress. Our everhastier decisions and actions do not respond to our long-term understanding, or to the gravity of responsibility we bear. “The

The term ‘race’ has deliberately been placed within inverted commas in order to stress that it is not a scientific term. Whereas it was for some time fashionable to divide humanity into four main races, and racial labels are still used to classify people in some countries (such as the USA), modern genetics tends not to speak of races. There are two principal reasons for this. First, there has always been so much interbreeding between human populations that it would be meaningless to talk of fixed boundaries between races. Second, the distribution of hereditary physical traits does not follow clear boundaries (Cavalli-Sforza et al., 1994). In other

Our slowest defensive response is through natural selection, which changes our gene frequencies from generation to generation. For almost any disease, some people prove to be genetically more resistant than are others. In an epidemic those people with genes for resistance to that particular microbe are more likely to survive than are people lacking such genes. As a result, over the course of history, human populations repeatedly exposed to a particular pathogen have come to consist of a higher proportion of individuals with those genes for resistance—just because unfortunate individuals without the genes were less likely to survive to pass their genes on to babies.
Jared Diamond (Guns, Germs, and Steel: The Fates of Human Societies (20th Anniversary Edition))
But this consensus view of many anthropologists and geneticists has morphed, seemingly without questioning, into an orthodoxy that the biological differences among human populations are so modest that they should in practice be ignored—and moreover, because the issues are so fraught, that study of biological differences among populations should be avoided if at all possible. It should come as no surprise, then, that some anthropologists and sociologists see genetic research into differences across populations, even if done in a well-intentioned way, as problematic. They are concerned that work on such differences will be used to validate concepts of race that should be considered discredited.
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
Camara Jones, a prominent medical researcher of health disparities, explained it this way to bioethics scholar Dorothy Roberts: “People are born with ancestry that comes from their parents but are assigned a race.” People from the same ethnic groups that are native to certain geographic regions typically share the same genetic profile. Geneticists call them “populations.” When geneticists compare these ethnic populations, they find there is more genetic diversity between populations within Africa than between Africa and the rest of the world. Ethnic groups in Western Africa are more genetically similar to ethnic groups in Western Europe than to ethnic groups in Eastern Africa. Race is a genetic mirage.
Ibram X. Kendi (How to Be an Antiracist)
It will be noticed that the fundamental theorem proved above bears some remarkable resemblances to the second law of thermodynamics. Both are properties of populations, or aggregates, true irrespective of the nature of the units which compose them; both are statistical laws; each requires the constant increase of a measurable quantity, in the one case the entropy of a physical system and in the other the fitness, measured by m, of a biological population. As in the physical world we can conceive the theoretical systems in which dissipative forces are wholly absent, and in which the entropy consequently remains constant, so we can conceive, though we need not expect to find, biological populations in which the genetic variance is absolutely zero, and in which fitness does not increase. Professor Eddington has recently remarked that 'The law that entropy always increases—the second law of thermodynamics—holds, I think, the supreme position among the laws of nature'. It is not a little instructive that so similar a law should hold the supreme position among the biological sciences. While it is possible that both may ultimately be absorbed by some more general principle, for the present we should note that the laws as they stand present profound differences—-(1) The systems considered in thermodynamics are permanent; species on the contrary are liable to extinction, although biological improvement must be expected to occur up to the end of their existence. (2) Fitness, although measured by a uniform method, is qualitatively different for every different organism, whereas entropy, like temperature, is taken to have the same meaning for all physical systems. (3) Fitness may be increased or decreased by changes in the environment, without reacting quantitatively upon that environment. (4) Entropy changes are exceptional in the physical world in being irreversible, while irreversible evolutionary changes form no exception among biological phenomena. Finally, (5) entropy changes lead to a progressive disorganization of the physical world, at least from the human standpoint of the utilization of energy, while evolutionary changes are generally recognized as producing progressively higher organization in the organic world.
Ronald A. Fisher (The Genetical Theory of Natural Selection)
The concern is so acute that the political scientist Jacqueline Stevens has even suggested that research and even emails discussing biological differences across populations should be banned, and that the United States “should issue a regulation prohibiting its staff or grantees…from publishing in any form—including internal documents and citations to other studies—claims about genetics associated with variables of race, ethnicity, nationality, or any other category of population that is observed or imagined as heritable unless statistically significant disparities between groups exist and description of these will yield clear benefits for public health, as deemed by a standing committee to which these claims must be submitted and authorized.
David Reich (Who We Are and How We Got Here: Ancient DNA and the New Science of the Human Past)
I am fascinated by the evolution of language, and how local versions diverge to become dialects like Cornish English and Geordie and then imperceptibly diverge further to become mutually unintelligible but obviously related languages like German and Dutch. The analogy to genetic evolution is close enough to be illuminating and misleading at the same time. When populations diverge to become species, the time of separation is defined as the moment when they can no longer interbreed. I suggest that two dialects should be deemed to reach the status of separate languages when they have diverged to an analogously critical point: the point where, if a native speaker of one attempts to speak the other it is taken as a compliment rather than as an insult.
Richard Dawkins (An Appetite for Wonder: The Making of a Scientist)
In the case of food, if the argument is valid that we need some kind of genetic modification to help feed the world’s growing population, then I believe that we cannot simply dismiss this branch of genetic technology. However, if, as suggested by its critics, this argument is merely a front for motives that are primarily commercial—such as producing food that will simply have a longer lasting shelf life, that can be more easily exported from one side of the world to the other, that is more attractive in appearance and more convenient in consumption, or creating grains and cereals engineered not to produce their own seeds so that farmers are forced to depend entirely upon the biotech companies for seeds—then clearly such practices must be seriously questioned.

Genetic analyses have confirmed the effects of status, power, and position on reproductive outcomes. Blood samples from 16 populations from around the former Mongolian empire revealed that 8 percent of the men bore a chromosomal “signature” characteristic of the Mongol rulers (Zerjal et al., 2003). The most prominent ruler, Genghis Khan, established large territories for his sons who had many wives and large harems. An astonishing 16 million men in that region are likely descendants of the ruler Genghis Khan, warranting the label “Genghis Khan effect.” Similar genetic results have been discovered in Ireland, where roughly one out of every five males in northwestern Ireland is likely to be a descendant of a single ruler (Moore, McEvoy, Cape, Simms, & Bradley, 2006).
David M. Buss (Evolutionary Psychology: The New Science of the Mind)
And by the early 1970s our little parable of Sam and Sweetie is exactly what happened to the North American Golden Retriever. One field-trial dog, Holway Barty, and two show dogs, Misty Morn’s Sunset and Cummings’ Gold-Rush Charlie, won dozens of blue ribbons between them. They were not only gorgeous champions; they had wonderful personalities. Consequently, hundreds of people wanted these dogs’ genes to come into their lines, and over many matings during the 1970s the genes of these three dogs were flung far and wide throughout the North American Golden Retriever population, until by 2010 Misty Morn’s Sunset alone had 95,539 registered descendants, his number of unregistered ones unknown. Today hundreds of thousands of North American Golden Retrievers are descended from these three champions and have received both their sweet dispositions and their hidden time bombs. Unfortunately for these Golden Retrievers, and for the people who love them, one of these time bombs happens to be cancer. To be fair, a so-called cancer gene cannot be traced directly to a few famous sires, but using these sires so often increases the chance of recessive genes meeting—for good and for ill. Today, in the United States, 61.4 percent of Golden Retrievers die of cancer, according to a survey conducted by the Golden Retriever Club of America and the Purdue School of Veterinary Medicine. In Great Britain, a Kennel Club survey found almost exactly the same result, if we consider that those British dogs—loosely diagnosed as dying of “old age” and “cardiac conditions” and never having been autopsied—might really be dying of a variety of cancers, including hemangiosarcoma, a cancer of the lining of the blood vessels and the spleen. This sad history of the Golden Retriever’s narrowing gene pool has played out across dozens of other breeds and is one of the reasons that so many of our dogs spend a lot more time in veterinarians’ offices than they should and die sooner than they might. In genetic terms, it comes down to the ever-increasing chance that both copies of any given gene are derived from the same ancestor, a probability expressed by a number called the coefficient of inbreeding. Discovered in 1922 by the American geneticist Sewall Wright, the coefficient of inbreeding ranges from 0 to 100 percent and rises as animals become more inbred.

gene, the mutation of whose DNA building blocks accelerated after the split between humans and chimpanzees, around 5.5 million years ago. The theory has also been put forward that the human brain is still evolving, on the grounds that a genetic variant of ASPM is thought to have originated only 5,800 years ago and then spread rapidly through the population. A genetic variant of the microcephalin gene (D allele of MCPH1), which regulates brain size, is thought to have only entered the DNA of Homo sapiens during the last ice age, around 37,000 years ago—yet 70 percent of the current world population carries this variant. A rapid increase of this kind is only possible if a variant confers a clear evolutionary advantage. Genes whose mutations are associated with human language have also been found. Mutations of the FOXP2 gene cause language and speech disorders that run in families. And ASPM and microcephalin also appear to have a linguistic connection.

In his history of biology, Ernst Mayr showed that many biologists originally rejected the theory of natural selection because of their belief that a species was a pure type defined by an essence. They could not wrap their minds around the concept that species are populations of variable individuals and that one can blend into another over evolutionary time.36 In this context, the fear of genetically modified foods no longer seems so strange: it is simply the standard human intuition that every living thing has an essence. Natural foods are thought to have the pure essence of the plant or animal and to carry with them the rejuvenating powers of the pastoral environment in which they grew. Genetically modified foods, or foods containing artificial additives, are thought of as being deliberately laced with a contaminant tainted by its origins in an acrid laboratory or factory. Arguments that invoke genetics, biochemistry, evolution, and risk analysis are likely to fall on deaf ears when pitted against this deep-rooted way of thinking.

Obviously there are quite a few factors that determine personality, including a person’s upbringing and experiences,” David continues, “but despite the peace and prosperity that had reigned in this country for nearly a century, it seemed advantageous to our ancestors to reduce the risk of these undesirable qualities showing up in our population by correcting them. In other words, by editing humanity. “That’s how the genetic manipulation experiment was born. It takes several generations for any kind of genetic manipulation to manifest, but people were selected from the general population in large numbers, according to their backgrounds or behavior, and they were given the option to give a gift to our future generations, a genetic alteration that would make their descendants just a little bit better.” I look around at the others.

JULIAN HUXLEY’S “EUGENICS MANIFESTO”: “Eugenics Manifesto” was the name given to an article supporting eugenics. The document, which appeared in Nature, September 16, 1939, was a joint statement issued by America’s and Britain’s most prominent biologists, and was widely referred to as the “Eugenics Manifesto.” The manifesto was a response to a request from Science Service, of Washington, D.C. for a reply to the question “How could the world’s population be improved most effectively genetically?” Two of the main signatories and authors were Hermann J. Muller and Julian Huxley. Julian Huxley, as this book documents, was the founding director of UNESCO from the famous Huxley family. Muller was an American geneticist, educator and Nobel laureate best known for his work on the physiological and genetic effects of radiation. Put into the context of the timeline, this document was published 15 years after “Mein Kampf” and a year after the highly publicized violence of Kristallnacht. In other words, there is no way either Muller or Huxley were unaware at the moment of publication of the historical implications of eugenic agendas.

Women select short-term sexual relationships when men cannot improve their children’s survival, when there are too few men, or when their upbringing has signaled that men are unreliable investors in their progeny. Short-term relationships for women often amount to serial monogamy in response to a population of males, none of whom can or will provide sustained economic and emotional commitment. And if she can maintain her attractiveness in the face of her increasing age, decreasing looks, and the handicap (from a prospective partner’s viewpoint) of already born children, she can also gain the advantage of genetic diversity and perhaps better genetic quality in her children. But the most secure and stable route is to attract a male who will commit, providing the long-term assistance and resources that she needs to raise multiple offspring simultaneously. Unfortunately that idea has occurred to other women also and she is in a competitive market-place. The currency of the marketplace is what men want in a female partner. To trade successfully, she must advertise her assets by showing that she has more desirable qualities than her female rivals.
Anne Campbell (A Mind of Her Own: The Evolutionary Psychology of Women)
A Code of Nature must accommodate a mixture of individually different behavioral tendencies. The human race plays a mixed strategy in the game of life. People are not molecules, all alike and behaving differently only because of random interactions. People just differ, dancing to their own personal drummer. The merger of economic game theory with neuroscience promises more precise understanding of those individual differences and how they contribute to the totality of human social interactions. It's understanding those differences, Camerer says, that will make such a break with old schools of economic thought. "A lot of economic theory uses what is called the representative agent model," Camerer told me. In an economy with millions of people, everybody is clearly not going to be completely alike in behavior. Maybe 10 percent will be of some type, 14 percent another type, 6 percent something else. A real mix. "It's often really hard, mathematically, to add all that up," he said. "It's much easier to say that there's one kind of person and there's a million of them. And you can add things up rather easily." So for the sake of computational simplicity, economists would operate as though the world was populated by millions of one generic type of person, using assumptions about how that generic person would behave. "It's not that we don't think people are different—of course they are, but that wasn't the focus of analysis," Camerer said. "It was, well, let's just stick to one type of person. But I think the brain evidence, as well as genetics, is just going to force us to think about individual differences." And in a way, that is a very natural thing for economists to want to do.

Multi-generational sexual child abuse is such a common cause of the proliferation of pedophilia that Hitler/Himmler research focused on this genetic trait for mind control purposes. While I personally could not relate to the idea of sex with a child, I had parents and brothers and sisters who did. I still believe that George Bush revealed today’s causation of the rapid rise in pedophilia through justifications I heard him state. The rape of a child renders them compliant and receptive to being led without question. This, Bush claims, would cause them to intellectually evolve at a rate rapid enough to “bring them up to speed” to grasp the artificial intelligence emanating from DARPA. He believed that this generation conditioned with photographic memory through abuse was necessary for a future he foresaw controlled by technology. Since sexual abuse enhanced photographic memory while decreasing critical analysis and free thought, there would ultimately be no free will soul expression controlling behavior. In which case, social engineering was underway to create apathy while stifling spiritual evolution. Nevertheless, to short sighted flat thinking individuals such as Bush, spiritual evolution was not a consideration anyway. Instead, controlling behavior in a population diminished by global genocide of ‘undesirables’ would result in Hitler’s ‘superior race’ surviving to claim the earth. Perceptual justifications such as these that were discussed at the Bohemian Grove certainly did not provide me with the complete big picture. It did, however, provide a view beyond the stereotyped child molester in a trench coat that helped in understanding the vast crimes and cover-ups being discussed at this seminar in Houston.

It should be clear by now that whatever Americans say about diversity, it is not a strength. If it were a strength, Americans would practice it spontaneously. It would not require “diversity management” or anti-discrimination laws. Nor would it require constant reminders of how wonderful it is. It takes no exhortations for us to appreciate things that are truly desirable: indoor plumbing, vacations, modern medicine, friendship, or cheaper gasoline. [W]hen they are free to do so, most people avoid diversity. The scientific evidence suggests why: Human beings appear to have deeply-rooted tribal instincts. They seem to prefer to live in homogeneous communities rather than endure the tension and conflict that arise from differences. If the goal of building a diverse society conflicts with some aspect of our nature, it will be very difficult to achieve. As Horace wrote in the Epistles, “Though you drive Nature out with a pitchfork, she will ever find her way back.” Some intellectuals and bohemians profess to enjoy diversity, but they appear to be a minority. Why do we insist that diversity is a strength when it is not? In the 1950s and 1960s, when segregation was being dismantled, many people believed full integration would be achieved within a generation. At that time, there were few Hispanics or Asians but with a population of blacks and whites, the United States could be described as “diverse.” It seemed vastly more forward-looking to think of this as an advantage to be cultivated rather than a weakness to be endured. Our country also seemed to be embarking on a morally superior course. Human history is the history of warfare—between nations, tribes, and religions —and many Americans believed that reconciliation between blacks and whites would lead to a new era of inclusiveness for all peoples of the world. After the immigration reforms of 1965 opened the United States to large numbers of non- Europeans, our country became more diverse than anyone in the 1950s would have imagined. Diversity often led to conflict, but it would have been a repudiation of the civil rights movement to conclude that diversity was a weakness. Americans are proud of their country and do not like to think it may have made a serious mistake. As examples of ethnic and racial tension continued to accumulate, and as the civil rights vision of effortless integration faded, there were strong ideological and even patriotic reasons to downplay or deny what was happening, or at least to hope that exhortations to “celebrate diversity” would turn what was proving to be a problem into an advantage. To criticize diversity raises the intolerable possibility that the United States has been acting on mistaken assumptions for half a century. To talk glowingly about diversity therefore became a form of cheerleading for America. It even became common to say that diversity was our greatest strength—something that would have astonished any American from the colonial era through the 1950s. There is so much emotional capital invested in the civil-rights-era goals of racial equality and harmony that virtually any critique of its assumptions is intolerable. To point out the obvious— that diversity brings conflict—is to question sacred assumptions about the ultimate insignificance of race. Nations are at their most sensitive and irrational where they are weakest. It is precisely because it is so easy to point out the weaknesses of diversity that any attempt to do so must be countered, not by specifying diversity’s strengths—which no one can do—but with accusations of racism.

HISTORICAL NOTE There are no nuclear power stations in Belarus. Of the functioning stations in the territory of the former USSR, the ones closest to Belarus are of the old Soviet-designed RBMK type. To the north, the Ignalinsk station, to the east, the Smolensk station, and to the south, Chernobyl. On April 26, 1986, at 1:23:58, a series of explosions destroyed the reactor in the building that housed Energy Block #4 of the Chernobyl Nuclear Power Station. The catastrophe at Chernobyl became the largest technological disaster of the twentieth century. For tiny Belarus (population: 10 million), it was a national disaster. During the Second World War, the Nazis destroyed 619 Belarussian villages along with their inhabitants. As a result of Chernobyl, the country lost 485 villages and settlements. Of these, 70 have been forever buried underground. During the war, one out of every four Belarussians was killed; today, one out of every five Belarussians lives on contaminated land. This amounts to 2.1 million people, of whom 700,000 are children. Among the demographic factors responsible for the depopulation of Belarus, radiation is number one. In the Gomel and Mogilev regions, which suffered the most from Chernobyl, mortality rates exceed birth rates by 20%. As a result of the accident, 50 million Ci of radionuclides were released into the atmosphere. Seventy percent of these descended on Belarus; fully 23% of its territory is contaminated by cesium-137 radionuclides with a density of over 1 Ci/km2. Ukraine on the other hand has 4.8% of its territory contaminated, and Russia, 0.5%. The area of arable land with a density of more than 1 Ci/km2 is over 18 million hectares; 2.4 thousand hectares have been taken out of the agricultural economy. Belarus is a land of forests. But 26% of all forests and a large part of all marshes near the rivers Pripyat, Dniepr, and Sozh are considered part of the radioactive zone. As a result of the perpetual presence of small doses of radiation, the number of people with cancer, mental retardation, neurological disorders, and genetic mutations increases with each year. —“Chernobyl.” Belaruskaya entsiklopedia On April 29, 1986, instruments recorded high levels of radiation in Poland, Germany, Austria, and Romania. On April 30, in Switzerland and northern Italy. On May 1 and 2, in France, Belgium, the Netherlands, Great Britain, and northern Greece. On May 3, in Israel, Kuwait, and Turkey. . . . Gaseous airborne particles traveled around the globe: on May 2 they were registered in Japan, on May 5 in India, on May 5 and 6 in the U.S. and Canada. It took less than a week for Chernobyl to become a problem for the entire world. —“The Consequences of the Chernobyl Accident in Belarus.” Minsk, Sakharov International College on Radioecology The fourth reactor, now known as the Cover, still holds about twenty tons of nuclear fuel in its lead-and-metal core. No one knows what is happening with it. The sarcophagus was well made, uniquely constructed, and the design engineers from St. Petersburg should probably be proud. But it was constructed in absentia, the plates were put together with the aid of robots and helicopters, and as a result there are fissures. According to some figures, there are now over 200 square meters of spaces and cracks, and radioactive particles continue to escape through them . . . Might the sarcophagus collapse? No one can answer that question, since it’s still impossible to reach many of the connections and constructions in order to see if they’re sturdy. But everyone knows that if the Cover were to collapse, the consequences would be even more dire than they were in 1986. —Ogonyok magazine, No. 17, April 1996

Quoting from page 308: The Competitive Exclusion Principle. No two organisms that compete in every activity can coexist indefinitely in the same environment. To coexist in time, organisms that are potentially completely competitive must be geographically isolated from each other. Otherwise, the one that is the less efficient yields to the more efficient, no matter how slight the difference. When two competing organisms coexist in the same geographical region, close examination always shows that they are not complete competitors, that one of them draws on a resource of the environment that is not available to the other. The corollary of the principle is that where there is no geographical isolation of genetically and reproductively isolated populations, there must be as many ecological niches as there are populations. The necessary condition for geographical coexistence is ecological specialization. Quoting page 86: The Exclusion Principle in biology plays a role similar to that of the Newtonian laws of motion in physics. It is a prime guide to the discovery of facts. We use the principle coupled with an axiom that is equally fundamental but which is almost never explicitly stated. We may call this the Inequality Axiom, and it states: If two populations are distinguishable, they are competitively unequal. Quoting page 87: Because of the compound-interest effect, no difference between competing populations is trivial. The slightest difference--and our acceptance of the Inequality Axiom asserts that a difference always exists--will result in the eventual extinction of one population by another. Put in another way, the Exclusion Principle tells us that two distinguishable populations can coexist in the same geographical region only if they live in different ecological worlds (thus avoiding complete competition and strict coexistence). Quoting page 88-89: Recall now the sequence of development in the process of speciation. Initially, the freshly isolated populations are nearly the same genetically; as time goes on, they diverge more and more. When they are distinguishably different, but still capable of interbreeding (if put together), we may speak of them as races. Ultimately, if the physical isolation endures long enough, they become so different from each other that interbreeding is impossible; we then say that the two populations are reproductively isolated from each other, and we speak of them as distinct species. ... What are the various possible outcomes of the speciation process, and what their relative frequencies? In the light of our assumption, it is clear that, most often, the speciation process will go no further than the formation of races before the physical isolation comes to an end and the germ plasm of the two races is melded into one by interbreeding. If, however, the speciation process continues until separate species are formed before the physical barrier breaks down, then what happens? The outcome is plainly dependent on the extent to which ecological differentiation has occurred: Do the two species occupy the same ecological niche, or not--that is, are they completely competitive? It seems probable that the degree of ecological differentiation will also increase with time spent in physical isolation. On this assumption, we would predict that, more often than not, "sister species" will be incapable of coexistence: when the physical isolation is at an end, one sister species will extinguish the other. Quoting page 253: The example illustrates the general rule that as a species becomes increasingly "successful," its struggle for existence ceases to be one of struggle with the physical environment or with other species and come to be almost exclusively competition with its own kind. We call that species most successful that has made its own kind its worst enemy. Man enjoys this kind of success.

Modeling the evolution of modularity became significantly easier after a kind of genetic variation was discovered by quantitative trait locus (QTL) mapping in the lab of James Cheverud at Washington University called 'relationship QTL' or r-QTL for short. An r-QTL is a genetic locus that affects the correlations between two quantitative traits (i.e. their variational relationship, and therefore, 'relationship' loci). Surprisingly, a large fraction of these so-mapped loci are also neutral with respect to the character mean. This means one can select on these 'neutral' r-QTLs without simultaneously changing the character mean in a certain way. It was easy to show that differential directional selection on a character could easily lead a decrease in genetic correlation between characters. Of course, it is not guaranteed that each and every population has the right kind of r-QTL polymorphisms, nor is it yet clear what kind of genetic architecture allows for the existence of an r-QTL. Nevertheless, these findings make it plausible that differential directional selection can enhance the genetic/variational individuality of traits and, thus, may play a role in the origin of evolutionary novelties by selecting for variational individuality. It must be added, though, that there has been relatively little research in this area and that we will need to see more to determine whether we understand what is going on here, if anything. In particular, one difficulty is the mathematical modeling of gene interaction (epistasis), because the details of an epistasis model determine the outcome of the evolution by natural selection. One result shows that natural selection increases or decreases mutational variance, depending on whether the average epistatic effects are positive or negative. This means that the genetic architecture is more determined by the genetic architecture that we start with than by the nature of the selection forces that act upon it. In other words, the evolution of a genetic architecture could be arbitrary with respect to selection.

It was discussed and decided that fear would be perpetuated globally in order that focus would stay on the negative rather than allow for soul expression to positively emerge. As people became more fearful and compliant, capacity for free thought and soul expression would diminish. There is a distinct inability to exert soul expression under mind control, and evolution of the human spirit would diminish along with freedom of thought when bombarded with constant negative terrors. Whether Bush and Cheney deliberately planned to raise a collective fear over collective conscious love is doubtful. They did not think, speak, or act in those terms. Instead, they knew that information control gave them power over people, and they were hell-bent to perpetuate it at all costs. Cheney, Bush, and other global elite ushering in the New World Order totally believed in the plan mapped out by artificial intelligence. They were allowing technology to dictate global control. “Life is like a video game,” Bush once told me at the rural multi-million dollar Lampe, Missouri CIA mind control training camp complex designed for Black Ops Special Forces where torture and virtual reality technologies were used. “Since I have access to the technological source of the plans, I dictate the rules of the game.” The rules of the game demanded instantaneous response with no time to consciously think and critically analyze. Constant conscious disruption of thought through television’s burst of light flashes, harmonics, and subconscious subliminals diminished continuity of conscious thought anyway, creating a deficit of attention that could easily be refocused into video game format. DARPA’s artificial intelligence was reliant on secrecy, and a terrifying cover for reality was chosen to divert people from the simple truth. Since people perceive aliens as being physical like them, it was decided that the technological reality could be disguised according to preconceptions. Through generations of genetic encoding dating back to the beginning of man, serpents incite an innate autogenic response system in humans to “freeze” in terror. George Bush was excited at the prospects of diverting people from truth by fear through perpetuating lizard-like serpent alien misconceptions. “People fear what they don’t know anyway. By compounding that fear with autogenic fear response, they won’t want to look into Pandora’s Box.” Through deliberate generation of fear; suppression of facts under the 1947 National Security Act; Bush’s stint as CIA director during Ford’s Administration; the Warren Commission’s whitewash of the Kennedy Assassination; secrecy artificially ensured by mind control particularly concerning DARPA, HAARP, Roswell, Montauk, etc; and with people’s fluidity of conscious thought rapidly diminishing; the secret government embraced the proverbial ‘absolute power that corrupts absolutely.’ According to New World Order plans being discussed at the Grove, plans for reducing the earth’s population was a high priority. Mass genocide of so-called “undesirables” through the proliferation of AIDS4 was high on Bush’s agenda. “We’ll annihilate the niggers at their source, beginning in South and East Africa and Haiti5.” Having heard Bush say those words is by far one of the most torturous things I ever endured. Equally as torturous to my being were the discussions on genetic engineering, human cloning, and depletion of earth’s natural resources for profit. Cheney remarked that no one would be able to think to stop technology’s plan. “I’ll destroy the planet first,” Bush had vowed.
