The Generous Man

When it comes to sex, Darwin didn't go far enough. Whereas his theory of natural selection dictates that species adapt the most efficient and logical traits (a streamlined fin, say, or a long wingspan), Generous Man makes the case that an animal's success, sexually, depends on developing the least efficient traits. Nørretranders uses as the central symbol of his theory the peacock's plumage. It's cumbersome, showy, and inefficient — and therefore terribly attractive to peahens. Put more simply, nothing shows a potential mate just how worthy you are as a partner than your ability to be wasteful and inefficient. It's like a man with money to burn. But money isn't everything: humans really measure their worth by doing something that's difficult. This is a central — though hitherto overlooked — factor in evolution. In order to win a partner to mate with, humans display their best sides. We strive for perfection, prove we are willing to help others, show consideration, and go out of our way. In other words, we are generous. This book shows how our nobler traits derive from our need for sex and are, in fact, the best way to get more of it.
