Now, habilis and erectus are 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." (BBC)
The palaeontologists should just accept that everybody comes from Adam and Eve instead of keep reivising their theory.
