In August I spoke at the Chautauqua Institution as part of their celebration of Darwin and Linnaeus. I posted the written version of my talk back then, but I’ve just received the audio recording and thought some folks might prefer listening to it instead. I actually prefer it too, because whenever I give talks, I look at what I’ve written and revise it as I talk. You can listen to the talk right here on the handy Odeo player I’ve embedded at the bottom of the post. Or you can download it to listen offline.
