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/

Besides that variation is already present. And you also won't know, if the resistant, better one, was already present earlier, while the weaker ones are actually the mutations.
Some of the arguments for evolution are actually of the nature of presenting a flat tire as a improvement in car design.

Yes very true :)

With malaria resistance it comes from having odd shaped red blood cells, however the odd shapes are more prone to blockage / move through the blood stream slower meaning a loss in general fitness.
