The evolutionary explanation for the peacock’s tail has an interesting implication, namely that the mind of one sex can help shape the body of the ot… - Steve Stewart-Williams

Most male gorillas either have a harem or do not have a mate; in contrast, most men who have more than zero mates have only one. This means that, whereas only harem-holding male gorillas contribute to the gene pool of the next generation, most human males who contribute to the gene pool do so in the context of a pair bond. Consequently, our evolved sexual nature has been shaped more by pair bonding than by harem polygyny.

Why would the omnipotent creator of the entire universe be so deeply attached to a bipedal, tropical ape? Why would He take on the bodily form of one of these peculiar tailless primates? Why would such a magnificent being be so obsessively, nit-pickingly preoccupied with trivial matters such as the dress code and sexual behaviour of one mammalian species, especially its female members?

As far as we know, no woman in the history of the species has ever given birth and thought: “Wait a minute! How do I know that this baby is mine and not some other woman’s?” In contrast, if a baby comes out of the body of a woman you slept with nine months ago, that’s not nearly as reliable a clue. As an old saying has it, maternity is a matter of fact, paternity a matter of opinion.
