Once again, we’re going beyond what’s in our textbooks to look at some related topics that connect with more recent developments in Biology. Please come to class on April 26th having listened to the Science Friday interview and watched TED Talk below to get a nice introduction to the concept of group selection, another means by which species can change over time.
- From Science Friday: “How Humans and Insects Conquered the Earth” (the bulk of the discussion of group selection is in the first half of the show)

Finally, here are some evolutionary perspectives on altruism and leadership from Simon Sinek (optional).
