Finds test human origins theory

Two hominid fossils discovered in Kenya are challenging a long-held view of human evolution.

Previously, the hominid Homo habilis was thought to have evolved into the more advanced Homo erectus, which evolved into us.

Now, habilis and erectus are now thought to be sister species that overlapped in time.

The new fossil evidence reveals an overlap of about 500,000 years during which Homo habilis and Homo erectus must have co-existed in the Turkana basin area, the region of East Africa where the fossils were unearthed.

"Their co-existence makes it unlikely that Homo erectus evolved from Homo habilis," said co-author Professor Meave Leakey, palaeontologist and co-director of the Koobi Fora Research Project.
