In closing, I've enjoyed this immensely thanks to you and to Slate . He argued with our take on this, protesting that he was bothered by irrelevance to the topic, not by the specific views held by posters. But his post still sounds good to us. What was really innovative and intriguing was the self-help spin the authors placed on this topic. I thought it could help, to know this stuff.
Sexual reproduction is no more that an effort to create genetic diversity.
The female genes trade off half their survival to improve the chances of the survival of the remainder, in the process of sexual reproduction. The great mass of Earth's organisms reproduce by simply dividing, but their survival strategy involves the speed of the process. The group does not need the alpha male for breeding purposes but to maintain group order. But since the alpha male tends to lead the group over a long period of the females' reproductive life, then the females would lose the advantage provided by the genetic diversity inherent in sexual reproduction, if they bred only with the alpha. Therefore there was an important genetic payoff for the female to seek partners other than the alpha male.
