In August 2008, a researcher’s young son found a remarkable rock at the Cradle of Humankind, near Johannesburg. In the rock hid the fossilised bones of a hominid (human-like being). The bones could help scientists understand a lot more about where humans really come from.

The boy’s father, paleoanthropologist Professor Lee Berger from Wits University, named the species Australopithecus Sediba. A few months later, also at the Malapa site, Berger found a rock containing the bones of another individual.
