It's been 50 years since the American paleoanthropologist Donald Johanson discovered the fossil of ancient hominin 'Lucy' in the Afar region of Ethiopia. The find took the story of human evolution back beyond 3 million years for the first time. Yet, despite largely centring on the African continent as the "cradle of mankind", the narrative of hominin fossil discovery is striking for its lack of African scientists.

In this week's episode, Yohannes Haile-Selassie, director of the Institute of Human Origins at Arizona State University in the US, explains why the story of ancient human origins is so western-centric, and why he's calling for the decolonisation of paleoanthropology.
