From time immemorial our species has gathered in tribes. We still do, even if our notion of tribe has been greatly diversified to include socio-economic, religious, political, and many other tribal kinds. To what extent does tribalism serve us still?

Join us for a timely live conversation with Duke University's evolutionary anthropologists Vanessa Woods and Brian Hare—authors most recently of Survival of the Friendliest— National Book Award winner novelist and essayist Tobin Anderson, and ICE@Dartmouth director, physicist and author Marcelo Gleiser.
