Sex at Dawn #72

August 13, 2010

This episode was recorded when Science for the People was called Skeptically Speaking.

We talk to author Christopher Ryan about his new book Sex at Dawn: The Prehistoric Origins of Modern Sexuality. We’ll discuss the most recent science and theories, and how social norms compare to our biological impulses. On Speaking Up, we have Derek Colanduno and Robynn “Swoopy” McCarthy with a look at the skeptical events happening at this year’s Dragon*Con!
