Team reconstructs ‘human ancestor’

The most complete view yet of a possible human ancestor uncovered in South Africa has revealed an intriguing mix of human and ape traits.


The two-million-year-old remains of several partial skeletons belonging to a previously unknown humanlike species were found in 2008 near Johannesburg.

The new analysis shows this species —Australopithecus sediba — had a human-like pelvis, hands and teeth, and a chimpanzee-like foot.

In six separate research reports, scientists probed further into the anatomy of a juvenile male skeleton, commonly referred to as MH1, a female skeleton, known as MH2, and an isolated adult tibia or shinbone, known as MH4.

The specimens were found at Malapa in the famous Cradle of Humankind World Heritage Site, just to the northwest of Johannesburg.

They were pulled from a pit — a depression left in the ground by a cave complex that lost its roof through erosion.

Scientists think the female and male could well have been mother and son.

It seems they died together in some tragic accident that saw them either fall into the cave complex or become stuck in it.
