Steve Mirsky, host of the excellent Science Talk, a podcast at Scientific American, talked to me the other day about all sorts of things. Part one of our talk is now online. We talk about my recent story about evolution in New York City. (Scientific American has a special issue dedicated to cities this month.) Listen to the podcast here.

Steve will be posting the second part of the talk soon.
