photoIn his new book, "Sex, Time and Power," Leonard Shlain looks at sex and how it shaped human evolution. He comes to the conclusion that language evolved so that men and women could negotiate terms of sex. And an awareness of time led men to become aware of their mortality, leading to the development of families. We look at women's sexuality, and its role in evolution.

Guests:

Leonard Shlain, surgeon and associate professor of surgery at University of California at San Francisco, author of "Sex, Time and Power: How Women's Sexuality Shaped Human Evolution," "Art & Physics: Parallel Visions in Space, Time and Light" and "The Alphabet Versus the Goddess: The Conflict Between World and Image."

This program aired on December 10, 2003.
