Organic Compounds Quotes

In order to be labeled organic, a crop must be grown without the use of certain synthetic pesticides and fertilizers, as specified by the USDA. Though produced with fewer synthetic compounds, organic vegetables are not necessarily tastier or more nutritious than their conventional counterparts. Also keep in mind that the certification process is often too expensive for small farms even though their practices may meet or exceed those set by the USDA. The smallest farms-those selling less than $5,000 worth of crops annually-may by law label their produce organic without being inspected or certified. Rather than rely on labeling, we prefer, when possible, to buy locally grown vegetables in their season.

technical debt’ that is not being paid down. It comes from taking shortcuts, which may make sense in the short-term. But like financial debt, the compounding interest costs grow over time. If an organization doesn’t pay down its technical debt, every calorie in the organization can be spent just paying interest, in the form of unplanned work.

For wicked people to do evil requires money, and good people superstition. Combining these elements and we get organized religion, but to achieve the worst of all evil conflate politics to the compound and the tragedies are endless.

Originally, the atoms of carbon from which we’re made were floating in the air, part of a carbon dioxide molecule. The only way to recruit these carbon atoms for the molecules necessary to support life—the carbohydrates, amino acids, proteins, and lipids—is by means of photosynthesis. Using sunlight as a catalyst the green cells of plants combine carbon atoms taken from the air with water and elements drawn from the soil to form the simple organic compounds that stand at the base of every food chain. It is more than a figure of speech to say that plants create life out of thin air.

The way mycelium produces enzymes to break down complex organic polymers into simpler compounds is a case study for how we can upcycle products and materials in our economy.

Passionate kissing alone, according to one study, results in the transfer of up to one billion bacteria from one mouth to another, along with about 0.7 milligrams of protein, 0.45 milligrams of salt, 0.7 micrograms of fat, and 0.2 micrograms of “miscellaneous organic compounds” (that is, bits of food)

Imagine trying to live in a world dominated by dihydrogen oxide, a compound that has no taste or smell and is so variable in its properties that it is generally benign but at other times swiftly lethal. Depending on its state, it can scald you or freeze you. In the presence of certain organic molecules it can form carbonic acids so nasty that they can strip the leaves from trees and eat the faces off statuary. In bulk, when agitated, it can strike with a fury that no human edifice could withstand. Even for those who have learned to live with it, it is an often murderous substance. We call it water.

IN 1953, STANLEY Miller, a graduate student at the University of Chicago, took two flasks—one containing a little water to represent a primeval ocean, the other holding a mixture of methane, ammonia, and hydrogen sulphide gases to represent Earth’s early atmosphere—connected them with rubber tubes, and introduced some electrical sparks as a stand-in for lightning. After a few days, the water in the flasks had turned green and yellow in a hearty broth of amino acids, fatty acids, sugars, and other organic compounds. “If God didn’t do it this way,” observed Miller’s delighted supervisor, the Nobel laureate Harold Urey, “He missed a good bet.

Whatever the nature of organizing relations may be,' J. Needham wrote in 1932, 'they form the central problem of biology, and biology will be fruitful in the future only if this is recognized. The hierarchy of relations, from the molecular structure of carbon compounds to the equilibrium of species and ecological wholes, will perhaps be the leading idea of the future.

The word Familia did not originally signify the ideal of our modern philistine, which is a compound of sentimentality and domestic discord. Among the Romans, in the beginning, it did not even refer to the married couple and their children, but to the slaves alone. Famulus means a household slave and familia signifies the totality of slaves belonging to one individual. The expression was invented by the romans to describe a new social organism, the head of which had under him wife and children and a number of slaves, under Roman paternal power, with power of life and death over them all.

It is well to know that prayer is not compounded of words, words that may fail to express what one desires to say, words that so often cloak inconsistencies, words that may have no deeper source than the physical organs of speech, words that may be spoken to impress mortal ears. The dumb may pray, and that too with the eloquence that prevails in heaven. Prayer is made up of heart throbs and the righteous yearnings of the soul, of supplication based on the realization of need, of contrition and pure desire.

Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired. Evolution has produced chemical compounds exquisitely organized to accomplish the most complicated and delicate of tasks. Many organic chemists viewing crystal structures of enzyme systems or nucleic acids and knowing the marvels of specificity of the immune systems must dream of designing and synthesizing simpler organic compounds that imitate working features of these naturally occurring compounds.

[Texting] discourages thoughtful discussion or any level of detail. And the addictive problems are compounded by texting's hyperimmediacy. E-mails take some time to work their way through the Internet, through switches and routers and servers, and they require that you take the step of explicitly opening them. Text messages magically appear on the screen of your phone and demand immediate attention from you. Add to that the social expectation that an unanswered text feels insulting to the sender, and you've got a recipe for addiction: You receive a text, and that activates your novelty centers. You respond and feel rewarded for having completed a task (even though that task was entirely unknown to you fifteen seconds earlier). Each of those delivers a shot of dopamine as your limbic system cries out "More! More! Give me more!

If you turn to a branch of those sciences that try to give a solution to the questions of life--to physiology, psychology, biology, sociology--there you will find an astounding poverty of thought, a very great lack of clarity, completely unjustified claims to answer questions that lie outside their subject and never-ending contradictions between one thinker and others, and even within himself. If you turn to a branch of the sciences that is not concerned with solving the questions of life but answers its own scientific, specialized questions, then you are captivated by the power of human intellect but you know in advance that there are no answers to the questions of life. These sciences directly ignore the questions of life. They say, "We have no answers to 'What are you?' and 'Why do you live?' and are not concerned with this; but if you need to know the laws of light, of chemical compounds, the laws of the development of organisms, if you need to know the laws of bodies and their forms and the relation of numbers and quantities, if you need to know the laws of your own mind, to all that we have clear, precise, and unquestionable answers.

Men presumably always have looked at flowers and been moved by their beauty and their smell: but only since the last century has it been possible to take a flower in your hand and know that you have between your fingers a complex association of organic compounds containing carbon, hydrogen, oxygen, nitrogen, phosphorus, and a great many other elements, in a complex structure of cells, all of which have evolved from a single cell; and to know something of the internal structure of these cells, and the processes by which they evolved, and the genetic process by which this flower was begun, and will produce other flowers; to know in detail how the light from it is reflected to your eye; and to know the details of those workings of your eye, and your nose, and your neurophysiological system, which enable you to see and smell and touch the flower. These inexhaustible and almost incredible realities which are all around us and within us are recent discoveries which are still being explored, while similar new discoveries continue to be made; and we have before us an endless vista of such new possibilities stretching into the future, all of it beyond man’s wildest dreams until almost the age we ourselves are living in. Popper’s ever present and vivid sense of this, and of the fact that every discovering opens up new problems for us, informs his theoretical methodology. He knows that our ignorance grows with our knowledge, and that we shall therefore always have more questions than answers.

In all honesty, I don’t envy you the possession of this power over memory, nor do I admire you. Because humans are usually completely unconcerned with the memories of other creatures. Human existence involves the willful destruction of the existential memories of other creatures and of your own memories as well. No life can survive without other lives, with the ecological memories of other living creatures have, memories of the environments in which the live. People don’t realize they need to rely on the memories of other organisms to survive. You think that flowers bloom in colorful profusion just to please your eyes. That a wild boar exists just to provide meat for your table. That a fish takes the bait just for you sake. That only you can mourn. That a stone falling into a gorge is of no significance. That a sambar deer, its head bent low to sip at a creek is not a revelation . . . When in fact the finest movement of any organism represents a change in an ecosystem.” The man with the compound eyes takes a deep sign and says: “But if you were any different you wouldn’t be human.

A powerful programming language is more than just a means for instructing a computer to perform tasks. The language also serves as a framework within which we organize our ideas about processes. Thus, when we describe a language, we should pay particular attention to the means that the language provides for combining simple ideas to form more complex ideas. Every powerful language has three mechanisms for accomplishing this: - primitive expressions, which represent the simplest entities the language is concerned with, - means of combination, by which compound elements are built from simpler ones, and - means of abstraction, by which compound elements can be named and manipulated as units.

For their neural networks to function, plants use virtually the same neurotransmitters we do, including the two most important: glutamate and GABA (gamma aminobutyric acid). They also utilize, as do we, acetylcholine, dopamine, serotonin, melatonin, epinephrine, norepinephrine, levodopa, indole-3-acetic acid, 5-hydroxyindole acetic acid, testosterone (and other androgens), estradiol (and other estrogens), nicotine, and a number of other neuroactive compounds. They also make use of their plant-specific neurotransmitter, auxin, which, like serotonin, for example, is synthesized from tryptophan. These transmitters are used, as they are in us, for communication within the organism and to enhance brain function.

The doctor looked shifty. “He’s still breathing,” he said. “Look, his pulse is nearly humming and he’s got a temperature you could fry eggs on.” He hesitated, aware that this was probably too straightforward and easily understood; medicine was a new art on the Disc, and wasn’t going to get anywhere if people could understand it. “Pyrocerebrum ouerf culinaire,” he said, after working it out in his head. “Well, what can you do about it?” said Arthur. “Nothing. He’s dead. All the medical tests prove it. So, er…bury him, keep him nice and cool, and tell him to come and see me next week. In daylight, for preference." "But he’s still breathing!” “These are just reflex actions that might easily confuse the layman,” said the doctor airily. Chidder sighed. He suspected that the Guild, who after all had an unrivalled experience of sharp knives and complex organic compounds, was much better at elementary diagnostics than were the doctors. The Guild might kill people, but at least it didn’t expect them to be grateful for it.

What—in other words—would modern boredom be without terror? One of the most boring documents of all time is the thick volume of Hitler’s Table Talk. He too had people watching movies, eating pastries, and drinking coffee with Schlag while he bored them, while he discoursed theorized expounded. Everyone was perishing of staleness and fear, afraid to go to the toilet. This combination of power and boredom has never been properly examined. Boredom is an instrument of social control. Power is the power to impose boredom, to command stasis, to combine this stasis with anguish. The real tedium, deep tedium, is seasoned with terror and with death. There were even profounder questions. For instance, the history of the universe would be very boring if one tried to think of it in the ordinary way of human experience. All that time without events! Gases over and over again, and heat and particles of matter, the sun tides and winds, again this creeping development, bits added to bits, chemical accidents—whole ages in which almost nothing happens, lifeless seas, only a few crystals, a few protein compounds developing. The tardiness of evolution is so irritating to contemplate. The clumsy mistakes you see in museum fossils. How could such bones crawl, walk, run? It is agony to think of the groping of the species—all this fumbling, swamp-creeping, munching, preying, and reproduction, the boring slowness with which tissues, organs, and members developed. And then the boredom also of the emergence of the higher types and finally of mankind, the dull life of paleolithic forests, the long long incubation of intelligence, the slowness of invention, the idiocy of peasant ages. These are interesting only in review, in thought. No one could bear to experience this. The present demand is for a quick forward movement, for a summary, for life at the speed of intensest thought. As we approach, through technology, the phase of instantaneous realiza-tion, of the realization of eternal human desires or fantasies, of abolishing time and space the problem of boredom can only become more intense. The human being, more and more oppressed by the peculiar terms of his existence—one time around for each, no more than a single life per customer—has to think of the boredom of death. O those eternities of nonexistence! For people who crave continual interest and diversity, O! how boring death will be! To lie in the grave, in one place, how frightful!

Despite the intervening six decades of scientific inquiry since Selye’s groundbreaking work, the physiological impact of the emotions is still far from fully appreciated. The medical approach to health and illness continues to suppose that body and mind are separable from each other and from the milieu in which they exist. Compounding that mistake is a definition of stress that is narrow and simplistic. Medical thinking usually sees stress as highly disturbing but isolated events such as, for example, sudden unemployment, a marriage breakup or the death of a loved one. These major events are potent sources of stress for many, but there are chronic daily stresses in people’s lives that are more insidious and more harmful in their long-term biological consequences. Internally generated stresses take their toll without in any way seeming out of the ordinary. For those habituated to high levels of internal stress since early childhood, it is the absence of stress that creates unease, evoking boredom and a sense of meaninglessness. People may become addicted to their own stress hormones, adrenaline and cortisol, Hans Selye observed. To such persons stress feels desirable, while the absence of it feels like something to be avoided. When people describe themselves as being stressed, they usually mean the nervous agitation they experience under excessive demands — most commonly in the areas of work, family, relationships, finances or health. But sensations of nervous tension do not define stress — nor, strictly speaking, are they always perceived when people are stressed. Stress, as we will define it, is not a matter of subjective feeling. It is a measurable set of objective physiological events in the body, involving the brain, the hormonal apparatus, the immune system and many other organs. Both animals and people can experience stress with no awareness of its presence. “Stress is not simply nervous tension,” Selye pointed out. “Stress reactions do occur in lower animals, and even in plants, that have no nervous systems…. Indeed, stress can be produced under deep anaesthesia in patients who are unconscious, and even in cell cultures grown outside the body.” Similarly, stress effects can be highly active in persons who are fully awake, but who are in the grip of unconscious emotions or cut off from their body responses. The physiology of stress may be triggered without observable effects on behaviour and without subjective awareness, as has been shown in animal experiments and in human studies.

In the intricate and mutable space-time geometry at the black hole, in-falling matter and energy interacted with the virtualities of the vacuum in ways unknown to the flatter cosmos beyond it. Quasi-stable quantum states appeared, linked according to Schrodinger's wave functions and their own entanglement, more and more of them, intricacy compounding until it amounted to a set of codes. The uncertainty principle wrought mutations; variants perished or flourished; forms competed, cooperated, merged, divided, interacted; the patterns multiplied and diversified; at last, along one fork on a branch of the life tree, thought budded. That life was not organic, animal and vegetable and lesser kingdoms, growing, breathing, drinking, eating, breeding, hunting, hiding; it kindled no fires and wielded no tools; from the beginning, it was a kind of oneness. An original unity differentiated itself into countless avatars, like waves on a sea. They arose and lived individually, coalesced when they chose by twos or threes or multitudes, reemerged as other than they had been, gave themselves and their experiences back to the underlying whole. Evolution, history, lives eerily resembled memes in organic minds. Yet quantum life was not a series of shifting abstractions. Like the organic, it was in and of its environment. It acted to alter its quantum states and those around it: action that manifested itself as electronic, photonic, and nuclear events. Its domain was no more shadowy to it than ours is to us. It strove, it failed, it achieved. They were never sure aboardEnvoy whether they could suppose it loved, hated, yearned, mourned, rejoiced. The gap between was too wide for any language to bridge. Nevertheless they were convinced that it knew something they might as well call emotion, and that that included wondering.

Hierarchies must rise and conglomerate as they extend over fewer and larger corporations. A seat in a high-rise job is the most coveted and contested product of expanding industry. The lack of schooling, compounded with sex, color, and peculiar persuasions, now keeps most people down. Minorities organized by women, or blacks, or the unorthodox succeed at best in getting some of their members through school and into an expensive job. They claim victory when they get equal pay for equal rank. Paradoxically, these movements strengthen the idea that unequal graded work is necessary and that high-rise hierarchies are necessary to produce what an egalitarian society needs. If properly schooled, the black porter will blame himself for not being a black lawyer. At the same time, schooling generates a new intensity of frustration which ultimately can act as social dynamite. 6

Not one of them [formulae] can be shown to have any existence, so that the formula of one of the simplest of organic bodies is confused by the introduction of unexplained symbols for imaginary differences in the mode of combination of its elements... It would be just as reasonable to describe an oak tree as composed of blocks and chips and shavings to which it may be reduced by the hatchet, as by Dr Kolbe's formula to describe acetic acid as containing the products which may be obtained from it by destructive influences. A Kolbe botanist would say that half the chips are united with some of the blocks by the force parenthesis; the other half joined to this group in a different way, described by a buckle; shavings stuck on to these in a third manner, comma; and finally, a compound of shavings and blocks united together by a fourth force, juxtaposition, is joined to the main body by a fifth force, full stop.

[The] structural theory is of extreme simplicity. It assumes that the molecule is held together by links between one atom and the next: that every kind of atom can form a definite small number of such links: that these can be single, double or triple: that the groups may take up any position possible by rotation round the line of a single but not round that of a double link: finally that with all the elements of the first short period [of the periodic table], and with many others as well, the angles between the valencies are approximately those formed by joining the centre of a regular tetrahedron to its angular points. No assumption whatever is made as to the mechanism of the linkage. Through the whole development of organic chemistry this theory has always proved capable of providing a different structure for every different compound that can be isolated. Among the hundreds of thousands of known substances, there are never more isomeric forms than the theory permits.

Our safety lies in repentance. Our strength comes of obedience to the commandments of God. My beloved brethren and sisters, I accept this opportunity in humility. I pray that I may be guided by the Spirit of the Lord in that which I say. I have just been handed a note that says that a U.S. missile attack is under way. I need not remind you that we live in perilous times. I desire to speak concerning these times and our circumstances as members of this Church. You are acutely aware of the events of September 11, less than a month ago. Out of that vicious and ugly attack we are plunged into a state of war. It is the first war of the 21st century. The last century has been described as the most war-torn in human history. Now we are off on another dangerous undertaking, the unfolding of which and the end thereof we do not know. For the first time since we became a nation, the United States has been seriously attacked on its mainland soil. But this was not an attack on the United States alone. It was an attack on men and nations of goodwill everywhere. It was well planned, boldly executed, and the results were disastrous. It is estimated that more than 5,000 innocent people died. Among these were many from other nations. It was cruel and cunning, an act of consummate evil. Recently, in company with a few national religious leaders, I was invited to the White House to meet with the president. In talking to us he was frank and straightforward. That same evening he spoke to the Congress and the nation in unmistakable language concerning the resolve of America and its friends to hunt down the terrorists who were responsible for the planning of this terrible thing and any who harbored such. Now we are at war. Great forces have been mobilized and will continue to be. Political alliances are being forged. We do not know how long this conflict will last. We do not know what it will cost in lives and treasure. We do not know the manner in which it will be carried out. It could impact the work of the Church in various ways. Our national economy has been made to suffer. It was already in trouble, and this has compounded the problem. Many are losing their employment. Among our own people, this could affect welfare needs and also the tithing of the Church. It could affect our missionary program. We are now a global organization. We have members in more than 150 nations. Administering this vast worldwide program could conceivably become more difficult. Those of us who are American citizens stand solidly with the president of our nation. The terrible forces of evil must be confronted and held accountable for their actions. This is not a matter of Christian against Muslim. I am pleased that food is being dropped to the hungry people of a targeted nation. We value our Muslim neighbors across the world and hope that those who live by the tenets of their faith will not suffer. I ask particularly that our own people do not become a party in any way to the persecution of the innocent. Rather, let us be friendly and helpful, protective and supportive. It is the terrorist organizations that must be ferreted out and brought down. We of this Church know something of such groups. The Book of Mormon speaks of the Gadianton robbers, a vicious, oath-bound, and secret organization bent on evil and destruction. In their day they did all in their power, by whatever means available, to bring down the Church, to woo the people with sophistry, and to take control of the society. We see the same thing in the present situation.

Fennel: contains strong antiviral compounds to fight off EBV. Healing Herbs and Supplements

It isn’t the height that scares me—the height makes me feel alive with energy, every organ and vessel and muscle in my body singing at the same pitch. Then I realize what it is. It’s him. Something about him makes me feel like I am about to fall. Or turn to liquid. Or burst into flames. My hand almost misses the next rung. “Now tell me…,” he says through a bursting breath, “what do you think learning strategy has to do with…bravery?” The question reminds me that he is my instructor, and I am supposed to learn something from this. A cloud passes over the moon, and the light shifts across my hands. “It…it prepares you to act,” I say finally. “You learn strategy so you can use it.” I hear him breathing behind me, loud and fast. “Are you all right, Four?” “Are you human, Tris? Being up this high…” He gulps for air. “It doesn’t scare you at all?” I look over my shoulder at the ground. If I fall now, I will die. But I don’t think I will fall. A gust of air presses against my left side, throwing my body weight to the right. I gasp and cling to the rungs, my balance shifting. Four’s cold hand clamps around one of my hips, one of his fingers finding a strip of bare skin just under the hem of my T-shirt. He squeezes, steadying me and pushing me gently to the left, restoring my balance. Now I can’t breathe. I pause, staring at my hands, my mouth dry. I feel the ghost of where his hand was, his fingers long and narrow. “You okay?” he asks quietly. “Yes,” I say, my voice strained. I keep climbing, silently, until I reach the platform. Judging by the blunted ends of metal rods, it used to have railings, but it doesn’t anymore. I sit down and scoot to the end of it so Four has somewhere to sit. Without thinking, I put my legs over the side. Four, however, crouches and presses his back to the metal support, breathing heavily. “You’re afraid of heights,” I say. “How do you survive in the Dauntless compound?” “I ignore my fear,” he says. “When I make decisions, I pretend it doesn’t exist.” I stare at him for a second. I can’t help it. To me there’s a

Ocean Acidification is sometimes referred to as Global Warming's Equally Evil Twin. The irony is intentional and fair enough as far as it goes... No single mechanism explains all the mass extinctions in the record and yet changes in ocean chemistry seem to be a pretty good predictor. Ocean Acidification played a role in at least 2 of the Big Five Extinctions: the End-Permian and the End-Triassic. And quite possibly it was a major factor in a third, the End-Cretaceous. ...Why is ocean acidification so dangerous? The question is tough to answer only because the list of reasons is so long. Depending on how tightly organisms are able to regulate their internal chemistry, acidification may affect such basic processes as metabolism, enzyme activity, and protein function. Because it will change the makeup of microbial communities, it will alter the availability of key nutrients, like iron and nitrogen. For similar reasons, it will change the amount of light that passes through the water, and for somewhat different reasons, it will alter the way sound propagates. (In general, acidification is expected to make the seas noisier.) It seems likely to promote the growth of toxic algae. It will impact photosynthesis—many plant species are apt to benefit from elevated CO2 levels—and it will alter the compounds formed by dissolved metals, in some cases in ways that could be poisonous. Of the myriad possible impacts, probably the most significant involves the group of creatures known as calcifiers. (The term calcifier applies to any organism that builds a shell or external skeleton or, in the case of plants, a kind of internal scaffolding out of the mineral calcium carbonate.)... Ocean acidification increases the cost of calcification by reducing the number of carbonate ions available to organisms that build shells or exoskeletons. Imagine trying to build a house while someone keeps stealing your bricks. The more acidified the water, the greater the energy that’s required to complete the necessary steps. At a certain point, the water becomes positively corrosive, and solid calcium carbonate begins to dissolve. This is why the limpets that wander too close to the vents at Castello Aragonese end up with holes in their shells. According to geologists who work in the area, the vents have been spewing carbon dioxide for at least several hundred years, maybe longer. Any mussel or barnacle or keel worm that can adapt to lower pH in a time frame of centuries presumably already would have done so. “You give them generations on generations to survive in these conditions, and yet they’re not there,” Hall-Spencer observed.

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.
