ABSTRACT
In this conference a good deal has been said about various relics left by early man, inferences that can be made from those relics, and questions raised by them. The questions I wish to raise are derived from research on another relic of early man, namely, modern man. What we find in modern man may raise rather pointed questions about the conditions of life over the long course of human evolution. It is particularly important to piece together clues regarding selective pressures among early men; these pressures must have shaped Homo sapiens, even though some of them may no longer be operating. Such material may give us valuable leads to discovery of basic characteristics of the contemporary human species.
