Actually this whole issue was well covered in Sir Ronald Fisher's 1930 book The Genetical Theory of Natural Selection . Its typical of Conservapedia that they don't mention Fishers book, or bother to respond to his research but just make the outrageous claim that the subject has been ignored. For many evolutionary scientists, Fishers book is considered second in importance only to Darwin's Origin of The Species.
There are many examples of evolution and natural selection on the exclusively female DNA in the X chromosomes and the mitochondria. One example is the development of malaria resistance in mitochondria - see http://en.wikipedia....ance_to_malaria
Care to demonstrate how resistance to malaria will make a human something other than a human.... If not then you're only citing small changes as "evidence" for the larger undemonstrative ones/
