In this second episode with archaeologist Dr Tim Forssman of the University of Pretoria, we take a closer look at his excavations at Little Muck and Dzombo and how the findings are shedding new light on the social relations between the San hunter-gatherers and early farmers of southern Africa. William finds out more about the "Kalahari debate" and the significance of Mapungubwe as an archaeological site. We also try our hand at the motto on South Africa's coat of arms. It is written in the Khoisan language of the /Xam people and is written as !ke e: /xarra //ke. Visit Tim's YouTube channel Bones&Stones.
