How African fossils put new spin on human origins story
The ancient remains of two human-like creatures found in South Africa could change the way we view our origins.
The 1.9-million-year-old fossils were first described in 2010, and given the species name Australopithecus sediba.
In-depth analysis, published in the journal Science, suggest this species was on the direct evolutionary line to us - Homo sapiens.
Here, Professor Chris Stringer, from the Natural History Museum, with the help of a cast of a A. sediba skull, describes the similarities that this species has with modern humans.
