Biology

"There are one hundred and ninety-three living species of monkeys and apes. One hundred and ninety-two of them are covered with hair. The exception is a naked ape self-named Homo sapiens."

"When a neo-Darwinian asks, “Why?” he is really asking “How did this come about?” He is a historian."

"Speaking of rhetoric, there should be an editorial rule that sentences associated with sociobiology, with efforts to "justify slavery, imperialism, racism, genocide, and to oppose equal rights or ERA" [a quote from S.L. Washburn] should always appear next to sentences associating environmentalist/learning theory, with efforts to justify propaganda, psychological terror, false advertisement, public indoctrination of hatred of foreigners, class enemies, minority groups, and so on and so on. Juxtaposing sociobiology and learning theory in this manner ought to show how unproductive it is to claim through innuendo or otherwise that science will lead to pseudoscience, will lead to man's inhumanity to man: ergo no science. Actually, one could argue that since man is such a cultural/learning animal we should have greater fear of learning theory since learning has far more power over man's behavior than genes. More specifically, if humans were not such learning animals, they would not learn all that Galton trash: ergo stop learning research so that bad guys will not use the data to teach the trash more effectively."

"I believe that human preferences came to be what they are in those millions of years in which our ancestors (whether or not they can be classified as human) lived in hunting bands and were those preferences which, in such conditions, were conducive to survival. It may be, therefore, that ultimately the work of sociobiologists (and their critics) will enable us to construct a picture of human nature in such detail that we can derive the set of preferences with which economists start. And if this result is achieved, it will enable us to refine our analysis of consumer demand and of other kinds of behaviour in the economics sphere."

"Even God cannot make two times two not make four."

"Thus perhaps the chief error of contemporary ‘sociobiology’ is to suppose that language, morals, law, and such like, are transmitted by the ‘genetic’ processes that molecular biology is now illuminating, rather than being the products of selective evolution transmitted by imitative learning. This idea is as wrong - although at the other end of the spectrum - as the notion that man consciously invented or designed institutions like morals, law, language or money, and thus can improve them at will, a notion that is a remnant of the superstition that evolutionary theory in biology had to combat: namely, that wherever we find order there must have been a personal orderer. Here again we find that an accurate account lies between instinct and reason."

"One of the peculiar features of history is that time always erodes advantage. Every invention sooner or later leads to a counterinvention. Every success contains the seeds of its own overthrow. Every hegemony comes to an end. Evolutionary history is no different."

"Nowhere in a zoo can a stranger encounter the look of an animal. At the most, the animal’s gaze flickers and passes on. They look sideways. They look blindly beyond. They scan mechanically. … That look between animal and man, which may have played a crucial role in the development of human society, and with which, in any case, all men had always lived until less than a century ago, has been extinguished. Looking at each animal, the unaccompanied zoo visitor is alone."

"The zoo animal in a cage exhibits all these abnormalities that we know so well from our human companions. Clearly, then, the city is not a concrete jungle, it is a human zoo."

"The directory of animals in the zoo ranges all the way from aardvark to zebra."

"Beauty is not arbitrary."

"Morality is never based upon nature."

"In the 1970s a few brave “sociobiologists” began to ask why, if other animals had evolved natures, humans would be exempt. They were vilified by the social science establishment and told to go back to ant-watching. Yet the question they had asked has not gone away. The principal reason for the hostility to sociobiology was that it seem to justify prejudice. This was simply a confusion. Genetic theories of racism, or classism or any kind of ism, have nothing in common with the notion that there is a universal, instinctive human nature. Indeed, they are fundamentally opposed because one believes in universals and the other in racial or class particulars."

"Wishful thinking that they are the same will be mere propaganda and no favor to either sex."

"Without this evolutionary history in mind, it is impossible to explain the different sexual mentalities of men and women."

"Anthropology consists of studying the differences between peoples. But this has led anthropologists to exaggerate the motes of racial difference and to ignore the beams of similarity."

"Sexual selection, as we have seen, is very different from natural selection in its effects, for it does not solve survival problems, it makes them worse."

"The stuff of anthropology—the traditions, the myths, the crafts, the language, the rituals—is to me but the froth on the surface. Beneath lie giant themes of humanity that are the same everywhere and that are characteristically male and female. To a Martian an anthropologist studying the differences between races would seem like a farmer studying the differences between each of the wheat plants in his field. The Martian is much more interested in the typical wheat plant. It is the human universals, not the differences, that are truly intriguing."

"We give boys tractors and girls dolls. We are reinforcing the stereotypical obsessions that they already have, but we are not creating them. This is something every parent knows. Despairingly they watch their son turns every stick into a sword or gun, while their daughter cuddles even the most inanimate object as if it were a doll."

"These facts have been first disputed and then actively suppressed by the educational establishment, which continues to insist that there are no differences in learning ability between boys and girls."

"There is a contradiction at the heart of feminism, one that few feminists have acknowledged. You cannot say, first, that men and women are equally capable of all jobs and, second, that if jobs were done by women, they would be done differently."

"These concerns (that is, about differences being used to justify unequal treatment) are fair. But just because people have exaggerated sexual differences in the past does not mean they cannot exist. There is no a priori reason for assuming that men and women have identical minds and no amount of wishing it were so will make it so if it is not so. Difference is not inequality."

"Wealth and power are means to women; women are means to genetic eternity….Men are to be exploited as providers of parental care, wealth, and genes. Cynical? Not half as cynical as most accounts of human history."

"Differences cannot be appealed to when they suit and denied when they do not."

"Men and women have different bodies. The differences are the direct result of evolution. Women’s bodies evolved to suit the demands of bearing and rearing children and of gathering plant food. Men’s bodies evolved to suit the demands of rising in a male hierarchy, fighting over women, and providing meat to a family. Men and women have different minds. The differences are the direct result of evolution. Women’s minds evolved to suit the demands of bearing and rearing children and of gathering plant food. Men’s minds evolved to suit the demands of rising in a male hierarchy, fighting over women, and providing meat to a family. The first paragraph is banal; the second inflammatory. The proposition that men and women have evolved different minds is anathema to every social scientist and politically correct individual. Yet I believe it to be true for two reasons. First, the logic is impeccable….Second, the evidence is overwhelming."

"And I end with one of the strangest of the consequences of sex: that the choosiness of human beings in picking their mates has driven the human mind into a history of frenzied expansion for no reason except that wit, virtuosity, inventiveness, and individuality turn other people on. It is a somewhat less uplifting perspective on the purpose of humanity than the religious one, but it is also rather liberating. Be different."

"If reproduction has been the reward and goal of power and wealth, then it is little wonder that it has also been a frequent cause and rewarding of violence."

"Monogamy, enforced by law, religion, or sanction, does seem to reduce murderous competition between men."

"One of the legacies of being an ape is intergroup violence."

"Power seeking is characteristic of all social mammals."

"Nature is not inflexible but malleable. Moreover, the most natural thing of all about evolution is that some natures will be pitted against others. Evolution does not lead to Utopia. It leads to a land in which what is best for a man may be the worst for another man, or what is best for a woman may be the worst for a man."

"And even where I am wrong about human nature, I am not wrong that there is such a nature to be sought."

"By describing adultery as a force that shaped our mating system, I am not “justifying” it. Nothing is more “natural” than people evolving the tendency to object to being cuckolded or cheated on, so if my analysis were to be interpreted as justifying adultery, it would be even more obviously interpreted as justifying the social and legal mechanisms for discouraging adultery. What I am claiming is that adultery and its disapproval are both “natural.”"

"The technological problems of suburban life may be a million miles from those of the Pleistocene savanna, but the human ones are not."

"The keystone of the new social structure, the pivotal factor of advancing civilization, the guide of the new religion, is biology; for man is an animal, and his characteristics, his requirements, and his reactions can be recorded and studied quite as carefully and precisely as those of any other animal."

"In history, and in evolution, progress is always a futile, Sisyphean struggle to stay in the same relative place by getting ever better at things. Cars move through the congested streets of London no faster than horse-drawn carriages did a century ago."

"In any case, no moral conclusions of any kind can be drawn from evolution."

"Jealousy is a “human universal,” and no culture lacks it, Despite the best efforts of anthropologists to find a society with no jealousy and so prove that it is an emotion introduced by pernicious social pressure or pathology, sexual jealousy seems to be an unavoidable part of being a human being."

"I am trying to describe the nature of humans, not prescribe their morality. That something is natural does not make it right."

"The Western cultural revolution that calls itself political correctness will no doubt stifle inquiries it does not like, such as those into the mental differences between men and women. I sometimes feel that we are fated never to understand ourselves because part of our nature is to turn every inquiry into an expression of our own nature: ambitious, illogical, manipulative, and religious."

"Group selection isn’t widely accepted by evolutionists for several reasons. First, it’s not an efficient way to select for traits, like altruistic behavior, that are supposed to be detrimental to the individual but good for the group. Groups divide to form other groups much less often than organisms reproduce to form other organisms, so group selection for altruism would be unlikely to override the tendency of each group to quickly lose its altruists through natural selection favoring cheaters. Further, little evidence exists that selection on groups has promoted the evolution of any trait. Finally, other, more plausible evolutionary forces, like direct selection on individuals for reciprocal support, could have made humans prosocial. These reasons explain why only a few biologists, like [[David Sloan Wilson|[David Sloan] Wilson]] and E. O. Wilson (no relation), advocate group selection as the evolutionary source of cooperation"

"I do not believe the fashionable dogma. Here is my argument to show that group selection is important. Imagine Alice and Bob to be two dodoes on the island of Mauritius before the arrival of human predators. Alice has superior individual fitness and has produced many grandchildren. Bob is individually unfit and unfertile. Then the predators arrive with their guns and massacre the progeny indiscriminately. The fitness of Alice and Bob is reduced to zero because their species made a bad choice long ago, putting on weight and forgetting how to fly. I do not take the Prisoner’s Dilemma seriously as a model of evolution of cooperation, because I consider it likely that groups lacking cooperation are like dodoes, losing the battle for survival collectively rather than individually."

"I will argue that group selection is important, contrary to the prevailing dogma among biologists. If group selection is important, Prisoner's Dilemma is not a good model for evolution. It is still an amusing toy for mathematicians and game-theorists to play with."

"Mendelian genetics was a rather abstract subject, since no one knew what genes were actually made of, or how they operated. The first great leap forward came when biochemists demonstrated that each step in a biochemical pathway was determined by a single gene. Each biosynthetic reaction is carried out by a specific protein known as an enzyme. Each enzyme has the ability to mediate one particular chemical reaction and so the one gene—one enzyme model of genetics (Fig. 1.02) was put forward by G. W. Beadle and E. L. Tatum, who won a Nobel prize for this scheme in 1958. Since then, a variety of exceptions to this simple scheme have been found. For example,some complex enzymes consist of multiple subunits, each of which requires a separate gene."

"Foods are digested in the human body to glucose, fatty acids, amino acids, and so on. These are used to produce energy to work and synthesize biomolecules, such as protein, nucleic acids, carbohydrate, and lipids. These changes are performed in cells and called metabolism. The metabolic pathways are composed of chemical reactions, which are catalyzed by enzyme."

"DIGESTION, n. The conversion of victuals into virtues. When the process is imperfect, vices are evolved instead -- a circumstance from which that wicked writer, Dr. Jeremiah Blenn, infers that the ladies are the greater sufferers from dyspepsia."

"Most Americans still believe that there is some biological legitimacy to our socially constructed racial categories. However, our modern scientific understanding of human genetic diversity flies in the face of all of our social stereotypes."

"In this unexpected scenario, the UFO occupants -- despite their obvious technological superiority -- are desperate for both human genetic material and the ability to feel human emotions -- particularly maternal emotions. Unlikely though it may seem, it is possible that the very survival of these extraterrestrials depends upon their success in absorbing chemical and psychological properties received from human abductees."

"The onion test is a simple reality check for anyone who thinks they can assign a function to every nucleotide in the human genome. Whatever your proposed functions are, ask yourself this question: Why does an onion need a genome that is about five times larger than ours?"

"Our sex is ultimately laid down by our genes."
