Infidelity is almost ubiquitous among the Himba, an indigenous group of pastoralists living in Namibia and Angola. In this episode, I speak with a human behavioral ecologist who can help us understand why. UCLA's Professor Brooke Scelza (@bascelza) has studied reproductive decision-making in these people for about a decade.

Come learn about an interesting culture and view infidelity through a new lens on this episode of Species.
