"This means—and religious people might find this a useful argument—that there was only one creation, one single event when life was born. Of course, that life might have been born on a different planet and seeded here by spacecraft, or there might even have been thousands of kinds of life at first, but only Luca survived in the ruthless free-for-all of the primeval soup. But until the genetic code was cracked in the 1960s, we did not know what we now know: that all life is one; seaweed is your distant cousin and anthrax one of your advanced relatives. The unity of life is an empirical fact. Erasmus Darwin was outrageously close to the mark: ‘One and the same kind of living filaments has been the cause of all organic life.’"

"The pope notwithstanding, the human species is by no means the pinnacle of evolution. Evolution has no pinnacle and there is no such thing as evolutionary progress."

"I know of no other way that human nature can have developed except by evolution, and there is now overwhelming evidence that there is no other way for evolution to work except by competitive reproduction. Those strains that reproduce persist; those that do not reproduce die out."

"Everything can be inherited except sterility. None of your direct ancestors died childless. Consequently, if we are to understand how human nature evolved, the very core of our inquiry must be reproduction, for reproductive success is the examination that all human genes must pass if they are not to be squeezed out by natural selection. Hence I am going to argue that there are very few features of the human psyche and nature that can be understand without reference to reproduction. I begin with sexuality itself."

"Reproducing sexually must improve an individual’s reproductive success or else sex would not persist. It is increasingly hard to understand how human beings came to be so clever without considering sexual competition."

"The idea that we were designed by our past was the principal insight of Charles Darwin. He was the first to realize that you can abandon divine creation of species without abandoning the argument from design. Every living thing is “designed” quite unconsciously by the selective reproduction of its own ancestors to suit a particular life-style."

"The study of human nature must have profound implications for the study of history, sociology, psychology, anthropology, and politics. Each of those disciplines is an attempt to understand human behavior, and if the underlying universals of human behavior are the product of evolution, then it is vitally important to understand what the evolutionary pressures were."

"I have gradually come to realize that almost all of social science proceeds as if 1859, the year of the publication of the Origin of Species, had never happened; it does so quite deliberately, for it insists that human culture is a product of our own free will and invention. Society is not the product of human psychology, it asserts, but vice versa. That sounds reasonable enough, and it would be splendid for those who believe in social engineering if it were true, but is is simply not true."

"We assume, and rightly that a Russian is just as human after two generations of oppressive totalitarianism as his grandfather was before him. But why, then, does social science proceed as if it were not the case, as if people’s natures are the products of their societies?"

"There is, therefore, such a thing as a universal human nature, common to all people."

"Just as human nature is the same everywhere, so it is recognizably the same as it was in the past."

"In behavior, as in appearance, every human individual is unique."

"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."

"Power seeking is characteristic of all social mammals."

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

"Life consists of the interplay of two kinds of chemicals: proteins and DNA."

"In other words, a record of our past is etched into our genes."

"In egalitarian societies, genes matter more."

"I think knowledge is a blessing, not a curse. This is especially true in the case of genetic knowledge."

"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."

"There are genes that have not changed much since the very first single-celled creatures populated the primeval ooze. There are genes that were developed when our ancestors were worm-like. There are genes that must have first appeared when our ancestors were fish. There are genes that exist in their present form only because of recent epidemics of disease. And there are genes that can be used to write the history of human migrations in the last few thousand years. From four billion years ago to just a few hundred years ago, the genome has been a sort of autobiography for our species, recording the important events as they occurred."

"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."

"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 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 I read the genome out to you at the rate of one word per second for eight hours a day, it would take me a century. If I wrote out the human genome, one letter per millimetre, my text would be as long as the River Danube. This is a gigantic document, an immense book, a recipe of extravagant length, and it all fits inside the microscopic nucleus of a tiny cell that fits easily upon the head of a pin."

"Beauty is not arbitrary."

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

"Morality is never based upon nature."

"Parasites invent new keys; hosts change the locks. There is an obvious group-selectionist argument here for sex: At any one time a sexual species will have lots of different locks; members of an asexual one will all have the same locks. So the parasite with the right key will quickly exterminate the asexual species but not the sexual one. Hence the well-known fact: By turning our fields over to monocultures of increasingly inbred strains of wheat and maize, we are inviting the very epidemics of disease that can only be fought by the pesticides we are forced to use in ever larger quantities."

"The longer your generation time, the more genetic mixing you need to combat your parasites."

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

"He (Thomas Ray) had discovered that the notion of a host-parasite arms race is one of the most basic and unavoidable consequences of evolution."

"Sex keeps the parasite guessing."

"A gene is by definition the descendant of a gene that was good at getting into future generations."

"Wherever you look in the historical record, the elites favored sons more than other classes….Lower down the social scale, daughters are preferred even today."

"The process of choosing somebody to have sex with, which used to be known as falling in love, is mysterious, cerebral, and highly selective."

"The sex that invests the least has time to spare to seek other mates. Therefore, broadly speaking, males invest less and seek quantity of mates, while females invest more and seek quality of mates."

"In species where the females get nothing useful from their mates, they seem to choose on aesthetic criteria alone."

"Sexual selection theory suggests that much of the behavior and some of the appearance of an animal is adapted not to help it survive but to help it to acquire the best or the most mates."

"Females choose; their choosiness is inherited; they prefer exaggerated ornaments; exaggerated ornaments are a burden to males. That much is now uncontroversial. Thus far Darwin was right."

"It is hardly surprising to find that the males best at seduction tend to be the best at other things as well; it does not prove that females are seeking good genes for their offspring."

"Advertising works. Brand names are better known if they are advertised with sexy or alluring pictures, and better-known brands sell better. Why does it work? Because the price the consumer would have to pay in ignoring the subliminal message is just too high. It is better to be fooled into buying the second-best ice cream than go to the bother of educating yourself to resist the salesmanship."

"As every bird-watcher knows, the beauty of a bird’s song is inversely correlated with the colorfulness of its plumage."

"Such “habituation” is just a property of the way brains work; our senses, and those of grackles, notice novelty and change, not steady states. The female preference did not evolve: it just is that way."

"If females have an existing aesthetic preference, it is only logical that males will evolve to exploit that preference."

"Human beings are a product of evolution as much as any slime mold, and the revolution of the last two decades in the way scientists now think about evolution has immense implications for mankind as will. To summarize the argument so far, evolution is more about reproduction of the fittest than survival of the fittest; every creature on earth is the product of a series of historical battles between parasites and hosts, between genes and other genes, between members of the same species, between members of one gender in competitions for members of the other gender. Those battles include psychological ones, to manipulate and exploit other members of the species; they are never won, for success in one generation only ensures that the foes of the next generation are fitter to fight harder. Life is a Sisyphean race, run ever faster toward a finish line that is merely the start of the next race."

"There is no nature that exists devoid of nurture; there is no nurture that develops without nature. To say otherwise is like saying that the area of a field is determined by its length but not its width. Every behavior is the product of an instinct trained by experience."

"The fifth method (that is, of analyzing human mating systems) is to compare mankind with other animals that share our highly social habits: with colonial birds, monkeys, and dolphins. As we shall see, the lesson they teach is that we are designed for a system of monogamy plagued by adultery."

"Humanity shares this profile of ardent, polygamist males and coy, faithful females with about 99 percent of all animal species, including our closest relatives, the apes."

"Computer viruses have since become a worldwide problem. It begins to look as if parasites are inevitable in any system of life."
