Though we can be fairly confident of human ancestry, back as far as
Homo erectus, beyond that is a contentious bunch of pretenders. Now we may have found the front-runner in the "Progenitor Stakes".
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.
But the team behind the discovery has now come back with a deeper analysis.
It tells Science magazine that features seen in the brain, feet, hands and pelvis of A. sediba all suggest this species was on the direct evolutionary line to us - Homo sapiens.
