genetic mystery

A post at http://anthropology.net (20th July 2012) is about a new paper published in the journal Cell, 'Evolutionary History and Adaptation from High Coverage Whole-Genome Sequencing of Diverse African Hunter Gatherers' – focussed on Pygmies from Cameroon and Khoesan Hadza and Sadawe (Tanzania). Their genetic diversity is surprising. The researchers were led to believe an otherwise unknown hominid or early human group has left a mark on the genetic history of these peoples. This led to Richard Klein saing the conclusions were irresponsible.
