If you donate DNA, what should scientists give in return? A 'pathbreaking' new model

Anthropologist Carla Handley is sitting cross-legged in a mud-walled house in a Kenyan village called Merti. She’s meeting with a man dressed in a flowing blue robe and a woven cap of red and white. His name is Wario Bala and he’s a member of Kenya’s Borana ethnic group, a nomadic people who raise cattle across Kenya’s northern regions.

Handley introduces herself, then adds that she’s “known locally as Chaltu Jillo Hanti” – the Borana language name bestowed on her by elders in the community. An interpreter translates and Wala laughs approvingly.

Then Handley points to a poster she’s brought with pictures on it.
