This week’s episode is with Dr. Matthew Herron, professor of Evolutionary Biology at Georgia Tech university. He found us through a series of articles on our blog about the emergence of multicellularity, and joined us for an excellent conversation on the topic. Over the course of the hour we covered all kinds of topics, from what the biology of Volvocine algae can tell us about our own multicelled nature, to more philosophical subjects like the emergence of life on earth, the value of careful speculation, and the way that basic science encourages us to pursue pure curiosity, simply for the sake of knowing what’s possible.
