A recent article described an old study done on the mating behavior of grouse, a chicken-like bird with similar intelligence issues. Typically, the male struts in front of a picky female who either enthusiastically mates with him or rejects his advances. The investigators selected several of the rejected males and surrounded them with realistic stuffed females. The real females who initially rejected them now found them to be very desirable and tried to make up for their mistake. As a teenager, I found this to be common behavior in human females, too, and wondered why.
This feckless behavior by females is, in fact, logical in evolutionary terms. If other females show a preference for, say, males with pink tail feathers, they should want their children to also have pink tail feathers to better pass on their gene pool. The human analog to pink tail feathers in our day would be our hair elaborately combed with a pompadour in front and a DA behind.
(Males are probably equally feckless, but that is harder to prove because males of all species will mate with just about anything.)
