In this episode, Lee Berger tells us about the Homo Naledi species that ritualistically buried their dead; George Nash on remarkable cave paintings in South Wales; Andrea Manica explains how our ancient ancestors evolved sickle cell to sidestep malaria; and Rod Flower on our forebears making medicine and mind-altering drugs.
