When Lee Berger entered the field of palaeoanthropology there was a one in 10,000,000 chance he would discover anything 'worthwhile' digging around South Africa. But this real-life Indiana Jones kept bucking the odds.

First, he found a pair of hominid teeth in southern Africa, and then after a fossil-hunting dry spell, his 9-year-old son Matthew found the jawbone of a completely new hominid species.

A few years later came Lee's most extraordinary discovery yet: a nearly inaccessible cave filled with skeletons of another new hominid species, which seemed to be violating all the rules.

The story of what happened in this cave revolutionises what we understand about the origins of our own human species.
