John Launer using one of Evolution’s greatest questions that are unanswered
Why do men occur? You it was because combining genes from different individuals—one male and one female—increases variation in a species, and it is variation that helps a species survive if you learned biology at sch l, your teachers will probably have told.
Unfortuitously, many evolutionary specialists stopped thinking in this description over three decades ago. From the reproductive point of view, no individual is interested in anything quite definitely beyond donating genes to another generation. So far as entire types are involved, they’ve been preserved or cleaned down pretty much at random, mostly in line with the whims of geology and climate. In addition, you don’t must have sexes to make variation the majority that is vast of like microbes joyfully mutate and differ without intercourse.
The evolutionist that is great Maynard Smith regarded sex as pretty much inexplicable. He chatted of “the twofold price of men.” First, it’s incomprehensible that any feminine should wish to discard half her genes and undertake somebody else’s, when theoretically she could simply create clones of by herself alternatively. Next, the men of numerous species are totally worthless at doing such a thing except sitting around, getting fat during the females’ cost, and—in the words of Richard Dawkins—duffing up other men.
