Citizen scientists and San trackers on the trail of our human origins along Southern Cape's stormy coast

From the shores of what was once a vast (but now inundated) Paleo-Agulhas Plain to Blombos Cave where humans began experimenting with art, this three-part series explores how the first Homo sapiens survived a brutal Ice Age and thrived to become us. But can the team find a 100,000-year-old human footprint?
