This Is Serious

Seems that evolution has been a problem for us men in more ways that one. The "Y" chromosome -- the essence of maleness -- doesn't recombine during mitosis, so it is passed on whole from father to son over the generations. The Incredible Shrinking Y [IHT.com]. What this means is that the Y has been "sheeding genes furiously over the course of evolutionary time, and it is now a fraction of the size of its partner, the X chromosome." Holy penis envy!!
