Brains and Bones and Radios

Tomorrow I'll be on the radio show Science and Society at 4:20 PM EST. It's my second time on the show. Last time around we talked about the past six million years of hominid evolution (podcast here). This time we're hoping to cover just a bit more ground: the past 600 million years of vertebrate evolution. We'll try to hit on the big innovations that our ancestors acquired after we parted ways with the squishy beasts--such as brains, bones, a smart immune system, and hands and feet. You can listen live here, and the podcast is here. (Scroll down a bit to my segment.)
