|Lucy, Glenn's ancient ancestor|
It is not even clear where in Africa modern humans evolved. Lucy suggested that Ethiopia was a crucial site. But in 2008 another species of Australopithecus, A. sediba, was discovered in South Africa. It lived around 2 million years ago, around when the Homo genus first emerged. The Taung Child also hailed from the same area, so the find suggested that South Africa could have been our species' birthplace.We may never find our true ancestorDespite this, White says Lucy's species is still the best candidate for a direct ancestor, but that more fossil evidence from that time is needed. "I am confident that the fossils will be found in that interval, because I know that in Ethiopia there are already four study areas with fossiliferous sediments of that age," he says.
