evolution as the origen of all species is what the person is talking about.
i have been to college. i have seen the goofy theories and goulds goulish works and they can have them all. it might explain where harvard gets their profs, but thats about it. and the study of human evolution? they are worse than on thin ice, they are in fantasy island - look boss, de plane!
frankly, since none of us were there, whatever you believe is a choice, pure and simple.
