S modern humans derive from a 200 kya african population (little or no interbreeding with archaic hs) S genetic material most diverse among african populations; suggest longer period of development here. S 8 base pair differences among exact populations (suggests some 30 kya development, not 1. 8 million)! N new tool kits based on antler, bone and wood.
