Sexual Selection Quotes

“Desire for beauty will endure and undermine the desire for truth.”
― Richard O. Prum, The Evolution of Beauty: How Darwin's Forgotten Theory of Mate Choice Shapes the Animal World—And Us

“Chaos, the eternal feminine, is also the crushing force of sexual selection. Women are choosy maters (unlike female chimps, their closest animal counterparts). Most men do not meet female human standards. It is for this reason that women on dating sites rate 85 percent of men as below average in attractiveness. It is for this reason that we all have twice as many female ancestors as male (imagine that all the women who have ever lived have averaged one child. Now imagine that half the men who have ever lived have fathered two children, if they had any, while the other half fathered none).41 It is Woman as Nature who looks at half of all men and says, “No!” For the men, that’s a direct encounter with chaos, and it occurs with devastating force every time they are turned down for a date. Human female choosiness is also why we are very different from the common ancestor we shared with our chimpanzee cousins, while the latter are very much the same. Women’s proclivity to say no, more than any other force, has shaped our evolution into the creative, industrious, upright, large-brained (competitive, aggressive, domineering) creatures that we are.42 It is Nature as Woman who says, “Well, bucko, you’re good enough for a friend, but my experience of you so far has not indicated the suitability of your genetic material for continued propagation.”

“David Buss has amassed a lot of evidence that human females across many cultures tend to prefer males who have high social status, good income, ambition, intelligence, and energy--contrary to the views of some cultural anthropologists, who assume that people vary capriciously in their sexual preferences across different cultures. He interpreted this as evidence that women evolved to prefer good providers who could support their families by acquiring and defending resources I respect his data enormously, but disagree with his interpretation.

The traits women prefer are certainly correlated with male abilities to provide material benefits, but they are also correlated with heritable fitness. If the same traits can work both as fitness indicators and as wealth indicators, so much the better. The problem comes when we try to project wealth indicators back into a Pleistocene past when money did not exist, when status did not imply wealth, and when bands did not stay in one place long enough to defend piles of resources. Ancestral women may have preferred intelligent, energetic men for their ability to hunt more effectively and provide their children with more meat. But I would suggest it was much more important that intelligent men tended to produce intelligent, energetic children more likely to survive and reproduce, whether or not their father stayed around. In other words, I think evolutionary psychology has put too much emphasis on male resources instead of male fitness in explaining women's sexual preferences.”

“[...] found that altruists have tend to more partners than the chronically self-interested, and that altruism is particularly good at elevating men's sexual success.”

“Homo sapiens exhibits traits consistent with a long history of polygyny or monogamy, and a relative absence of sperm competition.”
― Alan F. Dixson

“As a rule, sexually selected traits tend to be more condition-dependent --and thus more vulnerable to dysfunctions-- than other phenotypes. This contributes to explain why males are generally more vulnerable to both harmful mutations and environmental insults.”
― Marco del Giudice, Evolutionary Psychopathology: A Unified Approach

“Parental investment theory predicts that, on average, the sex that invests more in its offspring, including the size of gametes, gestation, lactation and child rearing, will be more selective when choosing a mate, and the less-investing sex will engage in more intra-sexual competition for access to mates.”
