slash UK slash AI for people. Welcome to Science Talk, the weekly podcast of Scientific American

for the seven days starting May 7th, 2008. I'm Steve Murski.

This week on the podcast, some of the less discussed aspects of evolution.

Darwin as a botanist with David Cohn, curator of an exhibit on that subject at the New York Botanical Garden,

David Cohn recently retired from Drew University as professor of science
