If we define "beauty" as having blue eyes (and only blue eyes), then we will, indeed, find a "gene for beauty." If we define "intelligence" as the performance on only one kind of test, then we will, indeed, find a "gene for intelligence." The genome is only a mirror for the breadth or narrowness of human imagination.

Genetic tests,” as Eric Topol, the medical geneticist described it, “are also moral tests. When you decide to test for ‘future risk,’ you are also, inevitably, asking yourself, what kind of future am I willing to risk?” Three case studies illustrate the power and the peril of using genes to predict “future risk.

Modern leftish philosophers tend to dismiss reason, science, objective reality and to insist that everything is culturally relative. More importantly, the leftist hates science and rationality because they classify certain beliefs as true (i.e., successful, superior) and other beliefs as false (i.e., failed, inferior). The leftist’s feelings of inferiority run so deep that he cannot tolerate any classification of some things as successful or superior and other things as failed or inferior. This also underlies the rejection by many leftists of the concept of mental illness and of the utility of IQ tests. Leftists are antagonistic to genetic explanations of human abilities or behavior because such explanations tend to make some persons appear superior or inferior to others. Leftists prefer to give society the credit or blame for an individual’s ability or lack of it. Thus if a person is “inferior” it is not his fault, but society’s, because he has not been brought up properly.

The most essential prediction of Darwinism is that, given an astronomical number of chances, unintelligent processes can make seemingly-designed systems, ones of the complexity of those found in the cell. ID specifically denies this, predicting that in the absence of intelligent input no such systems would develop. So Darwinism and ID make clear, opposite predictions of what we should find when we examine genetic results from a stupendous number of organisms that are under relentless pressure from natural selection. The recent genetic results are a stringent test. The results: 1) Darwinism’s prediction is falsified; 2) Design’s prediction is confirmed.

Noble, noble purpose. Unfortunately, drugs face all kinds of barriers. FDA testing alone takes five to eight years—if you’re lucky. Even worse, there are forces at work in the marketplace. Suppose you make a miracle drug for cancer or heart disease—as Genentech did. Suppose you now want to charge a thousand dollars or two thousand dollars a dose. You might imagine that is your privilege. After all, you invented the drug, you paid to develop and test it; you should be able to charge whatever you wish. But do you really think that the government will let you do that? No, Henry, they will not. Sick people aren’t going to pay a thousand dollars a dose for needed medication—they won’t be grateful, they’ll be outraged. Blue Cross isn’t going to pay it. They’ll scream highway robbery.

Gene patents are the point of greatest concern in the debate over ownership of human biological materials, and how that ownership might interfere with science. As of 2005—the most recent year figures were available—the U.S. government had issued patents relating to the use of about 20 percent of known human genes, including genes for Alzheimer’s, asthma, colon cancer, and, most famously, breast cancer. This means pharmaceutical companies, scientists, and universities control what research can be done on those genes, and how much resulting therapies and diagnostic tests will cost. And some enforce their patents aggressively: Myriad Genetics, which holds the patents on the BRCA1 and BRCA2 genes responsible for most cases of hereditary breast and ovarian cancer, charges $3,000 to test for the genes. Myriad has been accused of creating a monopoly, since no one else can offer the test, and researchers can’t develop cheaper tests or new therapies without getting permission from Myriad and paying steep licensing fees. Scientists who’ve gone ahead with research involving the breast-cancer genes without Myriad’s permission have found themselves on the receiving end of cease-and-desist letters and threats of litigation.

Wilson says his own private hell would be to be locked forever into a room full of people discussing the hypocrisies of religion, for example, that many religions preach love, compassion, and virtue yet sometimes cause war, hatred, and terrorism. From Wilson’s higher perspective, there is no contradiction. Group selection creates interlocking genetic and cultural adaptations that enhance peace, harmony, and cooperation within the group for the express purpose of increasing the group’s ability to compete with other groups. Group selection does not end conflict; it just pushes it up to the next level of social organization. Atrocities committed in the name of religion are almost always committed against out-group members, or against the most dangerous people of all: apostates (who try to leave the group) and traitors (who undermine the group).

Nature’s ultimate goal is to foster the growth of the individual from absolute dependence to independence — or, more exactly, to the interdependence of mature adults living in community. Development is a process of moving from complete external regulation to self-regulation, as far as our genetic programming allows. Well-self-regulated people are the most capable of interacting fruitfully with others in a community and of nurturing children who will also grow into self-regulated adults. Anything that interferes with that natural agenda threatens the organism’s chances for long-term survival.
Almost from the beginning of life we see a tension between the complementary needs for security and for autonomy. Development requires a gradual and ageappropriate shift from security needs toward the drive for autonomy, from attachment to individuation. Neither is ever completely lost, and neither is meant to predominate at the expense of the other. With an increased capacity for self-regulation in adulthood comes also a heightened need for autonomy — for the freedom to make genuine choices. Whatever undermines autonomy will be experienced as a source of stress. Stress is magnified whenever the power to respond effectively to the social or physical environment is lacking or when the tested animal or human being feels helpless, without meaningful choices — in other words, when autonomy is undermined.
Autonomy, however, needs to be exercised in a way that does not disrupt the social relationships on which survival also depends, whether with emotional intimates or with important others—employers, fellow workers, social authority figures. The less the emotional capacity for self-regulation develops during infancy and childhood, the more the adult depends on relationships to maintain homeostasis. The greater the dependence, the greater the threat when those relationships are lost or become insecure. Thus, the vulnerability to subjective and physiological stress will be proportionate to the degree of emotional dependence. To minimize the stress from threatened relationships, a person may give up some part of his autonomy. However, this is not a formula for health, since the loss of autonomy is itself a cause of stress.
The surrender of autonomy raises the stress level, even if on the surface it appears to be necessary for the sake of “security” in a relationship, and even if we subjectively feel relief when we gain “security” in this manner. If I chronically repress my emotional needs in order to make myself “acceptable” to other people, I increase my risks of having to pay the price in the form of illness. The other way of protecting oneself from the stress of threatened relationships is emotional shutdown. To feel safe, the vulnerable person withdraws from others and closes against intimacy. This coping style
may avoid anxiety and block the subjective experience of stress but not the physiology of it. Emotional intimacy is a psychological and biological necessity. Those who build walls against intimacy are not self-regulated, just emotionally frozen. Their stress from having unmet needs will be high.

But the history of Hopkins Hospital certainly isn’t pristine when it comes to black patients. In 1969, a Hopkins researcher used blood samples from more than 7,000 neighborhood children—most of them from poor black families—to look for a genetic predisposition to criminal behavior. The researcher didn’t get consent. The American Civil Liberties Union filed suit claiming the study violated the boys’ civil rights and breached confidentiality of doctor-patient relationships by releasing results to state and juvenile courts. The study was halted, then resumed a few months later using consent forms. And in the late nineties, two women sued Hopkins, claiming that its researchers had knowingly exposed their children to lead, and hadn’t promptly informed them when blood tests revealed that their children had elevated lead levels—even when one developed lead poisoning. The research was part of a study examining lead abatement methods, and all families involved were black. The researchers had treated several homes to varying degrees, then encouraged landlords to rent those homes to families with children so they could then monitor the children’s lead levels. Initially, the case was dismissed. On appeal, one judge compared the study to Southam’s HeLa injections, the Tuskegee study, and Nazi research, and the case eventually settled out of court. The Department of Health and Human Services launched an investigation and concluded that the study’s consent forms “failed to provide an adequate description” of the different levels of lead abatement in the homes.

our cognitive abilities as adults are heavily influenced by the social environment that we experienced during childhood, making it hard to discern any influence of preexisting genetic differences. Second, tests of cognitive ability (like IQ tests) tend to measure cultural learning and not pure innate intelligence, whatever that is.

But even if we were entirely successful at eliminating inequalities of outcome associated with being born into wealth or privilege, the inequalities that remain would not be purged of luck. There would still be another type of luck lurking in the background: genes. This is true not only of standardized test performance and IQ scores. Even appealing to so-called “character” traits (grit, perseverance, resourcefulness, motivation, curiosity, or any other non-cognitive skill) doesn’t get you out of grappling with genetics. These traits, too, are shaped by genetic differences between people. There is no measure of so-called “merit” that is somehow free of genetic influence or untethered from biology.

The cure for HIV?” “In 2007, a man named Timothy Ray Brown, known later as the Berlin patient, was cured of HIV. Brown was diagnosed with acute myeloid leukemia. His HIV-positive status complicated his treatment. During chemotherapy, he battled sepsis, and his physicians had to explore less traditional approaches. His hematologist, Dr. Gero Hutter, decided on a stem cell therapy: a full bone marrow transplant. Hutter actually passed over the matched bone marrow donor for a donor with a specific genetic mutation: CCR5-Delta 32. CCR5-Delta 32 makes cells immune to HIV.” “Incredible.” “Yes. At first, we thought the Delta 32 mutation must have arisen during the Black Death in Europe—about four to sixteen percent of Europeans have at least one copy. But we’ve traced it back further. We thought perhaps smallpox, but we’ve found Bronze Age DNA samples that carry it. The mutation’s origins are a mystery, but one thing is certain: the bone marrow transplant with CCR5-Delta 32 cured both Brown’s leukemia and HIV. After the transplant, he stopped taking his antiretrovirals and has never again tested positive for HIV.

Another example is tamoxifen, which is used for treatment of endocrine responsive breast cancer. Tamoxifen is given to patients postsurgery and dramatically reduces the rate of cancer recurrence. This drug is metabolized by cytochrome P450 2D6, the product of the CYP2D6 gene. Based on their DNA, there are patients with little CYP2D6 activity who are poor metabolizers and others with high activity who are extensive metabolizers. An FDA-approved genetic test exists for finding the variants of the CYP2D6 gene to help guide tamoxifen administration, but the lack of study data demonstrating its role in improving patient outcomes has, to date, led insurance companies to refuse to cover the test. Beyond having ramifications for drug efficacy, genetics also may play a role in the side effects of drugs.

The Living Word has various dimensions in relation to power and will to power. The spoken word stands at the very bottom of the involuted scale, being the faint echo of the inaudible Word. All beings, from the Gods to mankind, possess a sound, an essential name, a key note. By discovering what it is, one acquires the power to decompose and recreate it. It is also a mantra of voluntary death and resurrection. In the current parlance: the individual, chromosomic, genetic code has been deciphered. The secret has been penetrated. The name to which we refer corresponds to the supratemporal being and has nothing to do with the intimate, family name, although sometimes a delicate synchronicity is produced within a turn of the wheel, a mysterious lucky occurrence filled with meaning, and this name may also be symbolic.
'You must discover your Beloved's real name if you are to bring her back to life. And yours, too. They are the names of the God and Goddess to whom they will give a face. 'Of the God within you', as the Hindu greeting says: Namaste. 'I greet the God within you'.

The last case that Higdon presents is that of Emile, who is from Louisiana and in 1983 was visiting his sick parents at the hospital. One evening while he was at the hospital, a nurse named Debra offered to perform oral sex on him, but only if he wore a condom. After the act was complete, Debra offered to get rid of the condom filled with Emile’s sperm and must have impregnated herself, because nine months later genetic testing showed that Emile was the father of her baby. “The two never had sexual intercourse, only the one instance of oral sex with a condom.”10 The commonality in these three cases was that a man or boy was forced into fatherhood against his will and was then forced by the court against his will to pay child support. Can you imagine the uproar if a fifteen-year-old girl had sex with a thirty-four-year-old man and she was obligated in any way to him by the courts?

By the end of this decade, permutations and combinations of genetic variants will be used to predict variations in human phenotype, illness, and destiny. Some diseases might never be amenable to such a genetic test, but perhaps the severest variants of schizophrenia or heart disease, or the most penetrant forms of familial cancer, say, will be predictable by the combined effect of a handful of mutations. And once an understanding of "process" has been built into predictive algorithms, the interactions between various gene variants could be used to compute ultimate effects on a whole host of physical and mental characteristics beyond disease alone. Computational algorithms could determine the probability of the development of heart disease or asthma or sexual orientation and assign a level of relative risk for various fates to each genome. The genome will thus be read not in absolutes, but in likelihoods-like a report card that does not contain grades but probabilities, or a resume that does not list past experiences but future propensities. It will become a manual for previvorship.

It has always been asked in the spirit of: ‘What are the best sources of our knowledge – the most reliable ones, those which will not lead us into error, and those to which we can and must turn, in case of doubt, as the last court of appeal?’ I propose to assume, instead, that no such ideal sources exist – no more than ideal rulers – and that all ‘sources’ are liable to lead us into errors at times. And I propose to replace, therefore, the question of the sources of our knowledge by the entirely different question: ‘How can we hope to detect and eliminate error?’ The question of the sources of our knowledge, like so many authoritarian questions, is a genetic one. It asks for the origin of our knowledge, in the belief that knowledge may legitimize itself by its pedigree. The nobility of the racially pure knowledge, the untainted knowledge, the knowledge which derives from the highest authority, if possible from God: these are the (often unconscious) metaphysical ideas behind the question. My modified question, ‘How can we hope to detect error?’ may be said to derive from the view that such pure, untainted and certain sources do not exist, and that questions of origin or of purity should not be confounded with questions of validity, or of truth. …. The proper answer to my question ‘How can we hope to detect and eliminate error?’ is I believe, ‘By criticizing the theories or guesses of others and – if we can train ourselves to do so – by criticizing our own theories or guesses.’ …. So my answer to the questions ‘How do you know? What is the source or the basis of your assertion? What observations have led you to it?’ would be: ‘I do not know: my assertion was merely a guess. Never mind the source, or the sources, from which it may spring – there are many possible sources, and I may not be aware of half of them; and origins or pedigrees have in any case little bearing upon truth. But if you are interested in the problem which I tried to solve by my tentative assertion, you may help me by criticizing it as severely as you can; and if you can design some experimental test which you think might refute my assertion, I shall gladly, and to the best of my powers, help you to refute it.

If these d'Herelle bodies were really genes, fundamentally like our chromosome genes, they would give us an utterly new angle from which to attack the gene problem. They are filterable, to some extent isolable, can be handled in test-tubes, and their properties, as shown by their effects on the bacteria, can then be studied after treatment. It would be very rash to call these bodies genes, and yet at present we must confess that there is no distinction known between the genes and them. Hence we can not categorically deny that perhaps we may be able to grind genes in a mortar and cook them in a beaker after all.

The DNA is made up of two opposite spirals, positive and negative, which can easily be considered isomorphic to I Ching's yin () and yang (), or Leibniz's 0 and 1, or Joyce's and . These are bonded by four amino acids—adenine, guanine, cytosine and thymine, which are usually abbreviated A, G, C, T. If one dares to consider these isomorphic with active yang (), passive yang (), active yin () and passive yin (), or Leibniz's 01,11,10 and 00, or Joyce's and , then the parallel becomes staggering. In forming RNA messages—the genetic code—the T (thymine) drops out to be replaced by U (uracil) but we still have four elements—A, G, C, U—and if we permutate them by the now-familiar rule, making all possible combinations of three out of these basic four "letters," we get again 43 or 64 "words," which are the 64 elements of the genetic language.

Even seemingly simple scenarios of genetic screening force us to enter arenas of unnerving moral hazard. Take Friedman’s example of using a blood test to screen soldiers for genes that predispose to PTSD. At first glance, such a strategy would seem to mitigate the trauma of war: soldiers incapable of “fear extinction” might be screened and treated with intensive psychiatric therapies or medical therapies to return them to normalcy. But what if, extending the logic, we screen soldiers for PTSD risk before deployment? Would that really be desirable? Do we truly want to select soldiers incapable of registering trauma, or genetically “augmented” with the capacity to extinguish the psychic anguish of violence? Such a form of screening would seem to me to be precisely undesirable: a mind incapable of “fear extinction” is exactly the dangerous sort of mind to be avoided in war.

Living organisms were not independently created, but have descended and diversified over time from common ancestors. And thus, no other biological theory so elegantly explains this. Evolutionary theory has withstood the test of time—by way of vicarious experimentation, observation, analysis, and relentless criticism, though opposing viewpoints still cling to the concept of "design." As a person of the biological sciences, I cannot subscribe to such misguided notions that suggest static biological states. Clearly, proper examination of the natural world reveal evolutionary trajectories—some random, others nonrandom—and all having observable genetic implications. It is only when we apply evolutionary explanations to living systems that it becomes ever so clear. The world was not specifically designed with us in mind, but rather we long since adapted and conformed to our surroundings, only giving it the illusionary appearance of "design.

Dr. Kary Mullis, who won the Nobel Prize in Chemistry for inventing PCR, stated publicly numerous times that his invention should never be used for the diagnosis of infectious diseases. In July of 1997, during an event called Corporate Greed and AIDS in Santa Monica CA, Dr. Mullis explained on video, “With PCR you can find almost anything in anybody. It starts making you believe in the sort of Buddhist notion that everything is contained in everything else, right? I mean, because if you can model amplify one single molecule up to something that you can really measure, which PCR can do, then there’s just very few molecules that you don’t have at least one single one of them in your body. Okay? So that could be thought of as a misuse of it, just to claim that it’s meaningful.” Mikki explained, “The major issue with PCR is that it’s easily manipulated. It functions through a cyclical process whereby each revolution amplifies magnification. On a molecular level, most of us already have trace amounts of genetic fragments similar to coronavirus within us. By simply over-cycling the process, a negative result can be flipped to a positive. Governing bodies such as the CDC and the WHO can control the number of cases by simply advising the medical industry to increase or decrease the cycle threshold (CT).” In August of 2020, the New York Times reported that “a CT beyond 34 revolutions very rarely detect live virus, but most often, dead nucleotides that are not even contagious. In compliance with guidance from the CDC and the WHO, many top US labs have been conducting tests at cycle thresholds of 40 or more. NYT examined data from Massachusetts, New York, and Nevada and determined that up to 90 percent of the individuals who tested positive carried barely any virus.”17 90 percent! In May of 2021, CDC changed the PCR cycle threshold from 40 to 28 or lower for those who have been vaccinated. This one adjustment of the numbers allowed the vaccine pushers to praise the vaccines as a big success.

Although there are no set methods to test for psychiatric disorders like psychopathy, we can determine some facets of a patient’s mental state by studying his brain with imaging techniques like PET (positron emission tomography) and fMRI (functional magnetic resonance imaging) scanning, as well as genetics, behavioral and psychometric testing, and other pieces of information gathered from a full medical and psychiatric workup. Taken together, these tests can reveal symptoms that might indicate a psychiatric disorder. Since psychiatric disorders are often characterized by more than one symptom, a patient will be diagnosed based on the number and severity of various symptoms. For most disorders, a diagnosis is also classified on a sliding scale—more often called a spectrum—that indicates whether the patient’s case is mild, moderate, or severe. The most common spectrum associated with such disorders is the autism spectrum. At the low end are delayed language learning and narrow interests, and at the high end are strongly repetitive behaviors and an inability to communicate.

Ultimately, one goal of this research is to create a “smart pill” that could boost concentration, improve memory, and maybe increase our intelligence. Pharmaceutical companies have experimented with several drugs, such as MEM 1003 and MEM 1414, that do seem to enhance mental function. Scientists have found that in animal studies, long-term memories are made possible by the interaction of enzymes and genes. Learning takes place when certain neural pathways are reinforced as specific genes are activated, such as the CREB gene, which in turn emits a corresponding protein. Basically, the more CREB proteins circulating in the brain, the faster long-term memories are formed. This has been verified in studies on sea mollusks, fruit flies, and mice. The key property of MEM 1414 is that it accelerates the production of the CREB proteins. In lab tests, aged animals given MEM 1414 were able to form long-term memories significantly faster than a control group. Scientists are also beginning to isolate the precise biochemistry required in the formation of long-term memories, at both the genetic and the molecular level. Once the process of memory formation is completely understood, therapies will be devised to accelerate and strengthen this key process. Not only the aged and Alzheimer’s patients but eventually the average person may well benefit from this “brain boost.

If you were going to start a bioengineering company, Henry, what would you do? Would you make products to help mankind, to fight illness and disease? Dear me, no. That’s a terrible idea. A very poor use of new technology.” Hammond shook his head sadly. “Yet, you’ll remember,” he said, “the original genetic engineering companies, like Genentech and Cetus, were all started to make pharmaceuticals. New drugs for mankind. Noble, noble purpose. Unfortunately, drugs face all kinds of barriers. FDA testing alone takes five to eight years—if you’re lucky. Even worse, there are forces at work in the marketplace. Suppose you make a miracle drug for cancer or heart disease—as Genentech did. Suppose you now want to charge a thousand dollars or two thousand dollars a dose. You might imagine that is your privilege. After all, you invented the drug, you paid to develop and test it; you should be able to charge whatever you wish. But do you really think that the government will let you do that? No, Henry, they will not. Sick people aren’t going to pay a thousand dollars a dose for needed medication—they won’t be grateful, they’ll be outraged. Blue Cross isn’t going to pay it. They’ll scream highway robbery. So something will happen. Your patent application will be denied. Your permits will be delayed. Something will force you to see reason—and to sell your drug at a lower cost. From a business standpoint, that makes helping mankind a very risky business. Personally, I would never help mankind

When studies using mental ability test scores from children are considered, the heritability of mental ability is typically found to be about .40, and the effect of the common or shared environment is found to be almost as strong, about .35. In contrast, when studies using mental ability test scores from adults (or older adolescents) are considered, estimates of the heritability of mental ability are much higher, typically about .65, whereas estimates of common or shared environment effects are much lower, probably under .20 (see review by Haworth et al., 2010). These findings indicate that differences among children in their levels of mental ability are attributable almost as much to their common environment—that is, to features of their family or household circumstances—as to their genetic inheritances. However, the findings also suggest that as children grow up, the differences among them in mental ability become less strongly related to the features of their common environments, and more strongly related to their genetic inheritances. In other words, the effect on one's mental ability of the family or household in which one is reared tends to become less important as one grows up, so that by adulthood one's level of mental ability is heavily dependent on one's genetic characteristics. It is as if one's level of mental ability—relative to that of other persons of the same age—can be raised (or lowered) during childhood by a particularly good (or poor) home environment, but then gradually returns to the level that one's genes tend to produce.

Trust in the familiar seems to be matched by wariness of the unfamiliar. Jennifer Richeson of Northwestern University has conducted experiments in which white subjects had to interact in some way with a white or a black man before taking a mental test. Those who dealt with the black man got lower scores on the test, and their brain scans showed what Prof. Richeson called “heightened activity in areas of the brain associated with regulating our thoughts and emotions.” She interpreted this to mean that white subjects were struggling with the “awkwardness” or “exhaustion” of dealing with a black man, and that this interfered with their ability to take the mental test.
Researchers at Harvard and New York University had white and black subjects look repeatedly at a series of photographs of black and white faces, all with neutral expressions. Every time the subjects looked at one particular black face and one particular white face they got a mild electric shock. Lie detector-type devices showed that subjects would sweat—a typical stress reaction—when they saw the two faces they associated with the shocks. The researchers showed the photo series several times again, but without the shocks. White subjects quickly stopped sweating when they saw the white face formerly associated with the shock, but continued to sweat when they saw the black face. Black subjects had the opposite reaction, continuing to sweat when they saw the white but not the black face. Mahzarin Banaji, the study’s leader, concluded that this was a sign of natural human wariness of unfamiliar groups.

MRI testing again shows what may be the underlying brain mechanism. The amygdalae are two small lobes in the brain associated with fear, arousal, and emotions. When they are active, it is thought to be a sign of vigilance, meaning that the brain is wary and wants more information. A study at Massachusetts General Hospital found that when subjects looked at photographs of faces—half were white, half were black—MRI scans found high amygdala activity. This was considered to be a normal reaction to unfamiliar faces. When the subjects looked at the photographs a second time the faces were more familiar; only the other-race faces continued to provoke high amygdala activity. This was true for both blacks and whites, suggesting that encounters with people of different races keep the brain at a higher level of watchfulness.
Amygdalae notice race even when a person does not. William A. Cunningham of Ohio State University showed white subjects pictures of faces for only 30 milliseconds—not long enough for the subjects to be conscious of them—but black faces triggered greater amygdala activity than white faces. When he showed faces for a half a second—long enough for people to notice race—he found that black faces prompted greater activity in the pre-frontal areas, a part of the brain associated with detecting internal conflicts and controlling conscious behavior. This suggested the subjects were trying to suppress certain feelings about blacks.
Steven Neuberg of Arizona State University attributes instinctive bias to evolution during our hunter-gatherer past. “By nature, people are group-living animals—a strategy that enhances individual survival and leads to what we might call a ‘tribal psychology’, ” he says. “It was adaptive for our ancestors to be attuned to those outside the group who posed threats such as to physical security, health or economic resources.

Until recently, three unspoken principles have guided the arena of genetic diagnosis and intervention. First, diagnostic tests have largely been restricted to gene variants that are singularly powerful determinants of illness—i.e., highly penetrant mutations, where the likelihood of developing the disease is close to 100 percent (Down syndrome, cystic fibrosis, Tay-Sachs disease). Second, the diseases caused by these mutations have generally involved extraordinary suffering or fundamental incompatibilities with “normal” life. Third, justifiable interventions—the decision to abort a child with Down syndrome, say, or intervene surgically on a woman with a BRCA1 mutation—have been defined through social and medical consensus, and all interventions have been governed by complete freedom of choice. The three sides of the triangle can be envisioned as moral lines that most cultures have been unwilling to transgress. The abortion of an embryo carrying a gene with, say, only a ten percent chance of developing cancer in the future violates the injunction against intervening on low-penetrance mutations. Similarly, a state-mandated medical procedure on a genetically ill person without the subject’s consent (or parental consent in the case of a fetus) crosses the boundaries of freedom and noncoercion. Yet it can hardly escape our attention that these parameters are inherently susceptible to the logic of self-reinforcement. We determine the definition of “extraordinary suffering.” We demarcate the boundaries of “normalcy” versus “abnormalcy.” We make the medical choices to intervene. We determine the nature of “justifiable interventions.” Humans endowed with certain genomes are responsible for defining the criteria to define, intervene on, or even eliminate other humans endowed with other genomes. “Choice,” in short, seems like an illusion devised by genes to propagate the selection of similar genes.

Myself and my colleague Guy Madison (Dutton & Madison, 2017) inadvertently provided evidence for the Finnish inferiority complex in a study we did of every marriage between a Finn and a foreigner that took place in Finland in the year 2013. On average, males and females operate different sexual selection strategies. Males have nothing to lose from the sexual encounter, so it makes sense for them, if they can get away with it, to have as much sex as possible with as many different women as possible in order to maximise the probability that their genes will be passed on. Accordingly, they select for youth and beauty, as these are markers of fertility and health. The essence of beauty is a symmetrical face and a such face implies a low level of mutant genes and thus sound genetic health. Females operate differently. As we discussed briefly earlier, they have a great deal to lose from the sexual encounter, because they can become pregnant, which carries with it a range of social and physical costs. This makes them more selective. Specifically, they are sexually attracted to high status men as these men will have the resources to provide for them and their child, meaning that both of them are more likely to survive (Buss, 1989). So, socioeconomically, women ‘marry up’ (hypergamously) and men ‘marry down’ (hypogamously). We would expect that nationality would be an aspect of status. We tested this by ranking different nationalities based on various criteria and especially how wealthy a country was. We predicted that, among marriages between a Finn and a foreigner, Finnish women would to a greater extent marry men that were from countries ranked as higher status than Finland while Finnish men would disproportionately marry women from lower status countries. This is, overall, what we found. However, we specifically found that, whatever the objective national status differences, Finnish women married Western European and Anglophone (USA, Canada and so on) men while Finnish men married Eastern European and East Asian (including Japanese) women. This would imply, whatever the economic reality, that Finns regard themselves as inferior to pretty much all Western Europeans. It also indicates that the Japanese – who are far wealthier than the Finns – regard themselves as inferior to the Finns, presumably because there is some idolization of whiteness or, possibly, as has been argued by a Japanese anthropologist, the Japanese specifically adore Finnish culture (Mitsui, 2012).

Washington University found that adding a single extra gene dramatically boosted a mouse’s memory and ability. These “smart mice” could navigate mazes faster, remember events better, and outperform other mice in a wide variety of tests. They were dubbed “Doogie mice,” after the precocious character on the TV show Doogie Howser, M.D. Dr. Tsien began by analyzing the gene NR2B, which acts like a switch controlling the brain’s ability to associate one event with another. (Scientists know this because when the gene is silenced or rendered inactive, mice lose this ability.) All learning depends on NR2B, because it controls the communication between memory cells of the hippocampus. First Dr. Tsien created a strain of mice that lacked NR2B, and they showed impaired memory and learning disabilities. Then he created a strain of mice that had more copies of NR2B than normal, and found that the new mice had superior mental capabilities. Placed in a shallow pan of water and forced to swim, normal mice would swim randomly about. They had forgotten from just a few days before that there was a hidden underwater platform. The smart mice, however, went straight to the hidden platform on the first try. Since then, researchers have been able to confirm these results in other labs and create even smarter strains of mice. In 2009, Dr. Tsien published a paper announcing yet another strain of smart mice, dubbed “Hobbie-J” (named after a character in Chinese cartoons). Hobbie-J was able to remember novel facts (such as the location of toys) three times longer than the genetically modified strain of mouse previously thought to be the smartest. “This adds to the notion that NR2B is a universal switch for memory formation,” remarked Dr. Tsien. “It’s like taking Michael Jordon and making him a super Michael Jordan,” said graduate student Deheng Wang. There are limits, however, even to this new mice strain. When these mice were given a choice to take a left or right turn to get a chocolate reward, Hobbie-J was able to remember the correct path for much longer than the normal mice, but after five minutes he, too, forgot. “We can never turn it into a mathematician. They are rats, after all,” says Dr. Tsien. It should also be pointed out that some of the strains of smart mice were exceptionally timid compared to normal mice. Some suspect that, if your memory becomes too great, you also remember all the failures and hurts as well, perhaps making you hesitant. So there is also a potential downside to remembering too much.

The way circus elephants are trained demonstrates this dynamic well: When young, they are attached by heavy chains to large stakes driven deep into the ground. They pull and yank and strain and struggle, but the chain is too strong, the stake too rooted. One day they give up, having learned that they cannot pull free, and from that day forward they can be “chained” with a slender rope. When this enormous animal feels any resistance, though it has the strength to pull the whole circus tent over, it stops trying. Because it believes it cannot, it cannot. “You’ll never amount to anything;” “You can’t sing;” “You’re not smart enough;” “Without money, you’re nothing;” “Who’d want you?;” “You’re just a loser;” “You should have more realistic goals;” “You’re the reason our marriage broke up;” “Without you kids I’d have had a chance;” “You’re worthless”—this opera is being sung in homes all over America right now, the stakes driven into the ground, the heavy chains attached, the children reaching the point they believe they cannot pull free. And at that point, they cannot. Unless and until something changes their view, unless they grasp the striking fact that they are tied with a thread, that the chain is an illusion, that they were fooled, and ultimately, that whoever so fooled them was wrong about them and that they were wrong about themselves—unless all this happens, these children are not likely to show society their positive attributes as adults. There’s more involved, of course, than just parenting. Some of the factors are so small they cannot be seen and yet so important they cannot be ignored: They are human genes. The one known as D4DR may influence the thrill-seeking behavior displayed by many violent criminals. Along with the influences of environment and upbringing, an elongated D4DR gene will likely be present in someone who grows up to be an assassin or a bank robber (or a daredevil). Behavioral geneticist Irving Gottesman: “Under a different scenario and in a different environment, that same person could become a hero in Bosnia.” In the future, genetics will play a much greater role in behavioral predictions. We’ll probably be able to genetically map personality traits as precisely as physical characteristics like height and weight. Though it will generate much controversy, parents may someday be able to use prenatal testing to identify children with unwanted personality genes, including those that make violence more likely. Until then, however, we’ll have to settle for a simpler, low-tech strategy for reducing violence: treating children lovingly and humanely.

Scientists have found that there are two important genes, the CREB activator (which stimulates the formation of new connections between neurons) and the CREB repressor (which suppresses the formation of new memories). Dr. Jerry Yin and Timothy Tully of Cold Spring Harbor have been doing interesting experiments with fruit flies. Normally it takes ten trials for them to learn a certain task (e.g., detecting an odor, avoiding a shock). Fruit flies with an extra CREB repressor gene could not form lasting memories at all, but the real surprise came when they tested fruit flies with an extra CREB activator gene. They learned the task in just one session. “This implies these flies have a photographic memory,” says Dr. Tully. He said they are just like students “who could read a chapter of a book once, see it in their mind, and tell you that the answer is in paragraph three of page two seventy-four.” This effect is not just restricted to fruit flies. Dr. Alcino Silva, also at Cold Spring Harbor, has been experimenting with mice. He found that mice with a defect in their CREB activator gene were virtually incapable of forming long-term memories. They were amnesiac mice. But even these forgetful mice could learn a bit if they had short lessons with rest in between. Scientists theorize that we have a fixed amount of CREB activator in the brain that can limit the amount we can learn in any specific time. If we try to cram before a test, it means that we quickly exhaust the amount of CREB activators, and hence we cannot learn any more—at least until we take a break to replenish the CREB activators. “We can now give you a biological reason why cramming doesn’t work,” says Dr. Tully. The best way to prepare for a final exam is to mentally review the material periodically during the day, until the material becomes part of your long-term memory. This may also explain why emotionally charged memories are so vivid and can last for decades. The CREB repressor gene is like a filter, cleaning out useless information. But if a memory is associated with a strong emotion, it can either remove the CREB repressor gene or increase levels of the CREB activator gene. In the future, we can expect more breakthroughs in understanding the genetic basis of memory. Not just one but a sophisticated combination of genes is probably required to shape the enormous capabilities of the brain. These genes, in turn, have counterparts in the human genome, so it is a distinct possibility that we can also enhance our memory and mental skills genetically. However, don’t think that you will be able to get a brain boost anytime soon. Many hurdles still remain. First, it is not clear if these results apply to humans.

The key point is that these patterns, while mostly stable, are not permanent: certain environmental experiences can add or subtract methyls and acetyls, changing those patterns. In effect this etches a memory of what the organism was doing or experiencing into its cells—a crucial first step for any Lamarck-like inheritance. Unfortunately, bad experiences can be etched into cells as easily as good experiences. Intense emotional pain can sometimes flood the mammal brain with neurochemicals that tack methyl groups where they shouldn’t be. Mice that are (however contradictory this sounds) bullied by other mice when they’re pups often have these funny methyl patterns in their brains. As do baby mice (both foster and biological) raised by neglectful mothers, mothers who refuse to lick and cuddle and nurse. These neglected mice fall apart in stressful situations as adults, and their meltdowns can’t be the result of poor genes, since biological and foster children end up equally histrionic. Instead the aberrant methyl patterns were imprinted early on, and as neurons kept dividing and the brain kept growing, these patterns perpetuated themselves. The events of September 11, 2001, might have scarred the brains of unborn humans in similar ways. Some pregnant women in Manhattan developed post-traumatic stress disorder, which can epigenetically activate and deactivate at least a dozen genes, including brain genes. These women, especially the ones affected during the third trimester, ended up having children who felt more anxiety and acute distress than other children when confronted with strange stimuli. Notice that these DNA changes aren’t genetic, because the A-C-G-T string remains the same throughout. But epigenetic changes are de facto mutations; genes might as well not function. And just like mutations, epigenetic changes live on in cells and their descendants. Indeed, each of us accumulates more and more unique epigenetic changes as we age. This explains why the personalities and even physiognomies of identical twins, despite identical DNA, grow more distinct each year. It also means that that detective-story trope of one twin committing a murder and both getting away with it—because DNA tests can’t tell them apart—might not hold up forever. Their epigenomes could condemn them. Of course, all this evidence proves only that body cells can record environmental cues and pass them on to other body cells, a limited form of inheritance. Normally when sperm and egg unite, embryos erase this epigenetic information—allowing you to become you, unencumbered by what your parents did. But other evidence suggests that some epigenetic changes, through mistakes or subterfuge, sometimes get smuggled along to new generations of pups, cubs, chicks, or children—close enough to bona fide Lamarckism to make Cuvier and Darwin grind their molars.
