The pace, the pace of which that the human minds have evolved over the last half-million years and more recently the last 200,000 years has been so frighteningly rapid that the evolution of cognitive function and perception in different ways, can only happen to the actions of a small number of genes. If one needed to adapt dozens of genes changes and concert, in order to acquire the penetrating minds that we now have, which our ancestors 500,000 years ago didn’t have, the evolution could not have taken, could not have occurred so quickly. And for that reason alone, one begins to suspect that the genetic differences between people who lived 500,000 years ago sever that cognitive functions than ours are not so large. Therefore, a rather small number of genes may be responsible for comforting us that powerful minds which we now, which most of us now possessed.
