“Survival of the Prettiest”
“Darwin conceived this idea largely because he found natural selection could not account for the ornaments seen in many animals, especially males, all over the world — the bright buttocks and faces of many monkeys and apes; the white legs and backside of the Banteng bull, in Malaysia; the elaborate feathers and mating dances of countless birds including bee-eaters and bell-birds, nightjars, hummingbirds and herons, gaudy birds of paradise and lurid pheasants, and the peacock, that showboat, whose extravagant tail seems a survival hindrance but so pleases females that well-fanned cocks regularly win their favor. Only a consistent preference for such ornament — in many species, a “choice exerted by the female” — could select for such decoration. This sexual selection,as Darwin called it, this taste for beauty rather than brawn, constituted an evolutionary mechanism separate, independent, and sometimes contrary to natural selection.
To Darwin’s dismay, many biologists rejected this theory. For one thing, Darwin’s elevation of sexual selection threatened the idea of natural selection as the one true and almighty force shaping life — a creative force powerful and concentrated enough to displace that of God. And some felt Darwin’s sexual selection gave too much power to all those females exerting choices based on beauty. As the zoologist St. George Jackson Mivart complained in an influential early review of “Descent,” “the instability of vicious feminine caprice” was too soft and slippery a force to drive something as important as evolution…
Like all selection, this is not intended to reach any particular goal; it just unfolds according to the demands of either fitness, or in this case, beauty. A trait selected for its beauty, of course, might create problems by selecting for ornaments that work against fitness. But, most crucially in the end, and often offsetting these problems, this “aesthetic” courtship, says Prum, creates an environment, temperaments and rituals — a sort of culture — that give the female sexual choice, autonomy and safety.”
Evolution is way more complicated than just the survival of the fittest, Darwin wasn’t some perfect genius whose words we study to find the truth, but reading about his other theories is interesting to think about because of the impact that his words have on society.
Early theories of evolution and genetics were used to prop up some of the worst atrocities of the 19th and 20th centuries, and are still part of white nationalist ideologies. It’s important to understand how these ideas are disseminated and filtered through social norms.
