Genetics to unlock secrets of Africa's past
In Europe, Neanderthal DNA has already been sequenced successfully. But ancient DNA has not yet been extracted from African hominid fossils, partly because very little organic material is preserved in African fossils more than 10,000 years old, as preservation requires cool, dry conditions.
Archaeologists have some potential sites in mind in South Africa, however. But most of the country's nine provinces — which have recently been given responsibility for granting permission for excavations — lack the infrastructure to administer such a mandate, resulting in an effective moratorium on excavations.
