Nicholas Christakis is a Professor at Yale University and an author. Much of what I've covered on the podcast has focussed on evolution's effects on the individual, but today we look at how evolution has shaped us as a collective. Expect to learn... Why is it that we live in groups? Why can we (mostly) rely on the person we're talking to to not lie to us, or kill us on sight? Why can we recognise different faces so effectively? And why do we even have different faces in the first place?
