Publisher's Summary

Cro-Magnon Man was smarter and generally more capable than we are. So why did he go extinct? Precisely because he was so capable. Whereas members of our species are weaklings who rely on others, members of his species had it in them to be rugged individualists; and that is what they did. But then, when circumstances became too severe, they had no social support and thus went extinct.
