Class Prep For Apr. 25: human evolution & group selection

To wrap up our look at evolution, we’re going beyond what’s in our textbooks to look at some related topics that connect with more recent developments in Biology. The TED Talk by Jonathan Haidt below should provide a nice introduction to the concept of group selection, another means by which species can change over time. The portion of the TED Radio Hour will then give you a sense of how group selection may have shaped us as a species. Also included here are excerpts from The Social Conquest of Earth, in case you’d like to get more familiarized with group selection.
