About this episode

In this special episode of Science in Action, Roland Pease travels to South Africa to gain a deeper understanding of human origins.

Along the way, he speaks to ichnologist Charles Helm and national parks ecologist Mike Fabricius, who take him to a special – and extremely windy – location, where early human footprints are permanently preserved in the rock. At the University of Cape Town, Roland speaks to Rieneke Weij and Georgina Luti. They are studying the geochemistry of rocks that existed in caves alongside our ancient relatives.

Across the city, in the Iziko South African Museum, Wendy Black and Amy Sephton discuss the ways in which we think about our deep past and how we can decolonise the human story.

Presenter: Roland Pease Producer: Ella Hubber Editor: Martin Smith Production Co-ordinator: Jana Bennett-Holesworth
