We are a species in which both sexes have their equivalents of the peacock’s tail. Indeed, when it comes to physical beauty, the usual sex difference… - Steve Stewart-Williams

It is not clear that people have fully taken on board the idea that humans are animals. If they had, then perhaps academic disciplines such as sociology and anthropology would be viewed as specialist branches of zoology; medical doctors would be viewed as a subtype of veterinarians (one that specializes in tending to the health needs of just one species); human rights would be viewed as a subset of animal rights; and the socialization of children would be viewed as one example of the training or domestication of animals (making parents and teachers a subtype of animal trainers).

"Once a suitable mate is located, humans engage in various peculiar mating rituals. The male, for example, may give the female a bundle of plant genitals (or “flowers”), or the pair may take turns making noises at each other while imbibing fermented plant juice." (Quote from an alien scientists report on our species.)

A similar analysis applies within the realm of mate preferences. Several commentators pointed out that sex differences in human mate preferences are generally quite small... As such, the central claim in EP [evolutionary psychology] should probably be "Human beings evolved to put a fair amount of weight on good looks in a mate" rather than "Men evolved to put more weight on good looks than women." Again, the latter statement is true but potentially misleading. This sounds like a contradiction, but it is not; the statement is misleading if it is given undue weight.
