A new paper in Nature uses mitochondrial DNA, specifically from the KhoeSan people of southern Africa, to suggest that anatomically modern humans developed in former wetlands about 200 ka ago in what is modern Botswana and spread from that area after 130 ka. Read about it at Earth-logs.

Remains of a Miocene ape from Bavaria reveal clear signs that it was bipedal and therefore a possible ancestor of hominins. Details are at Earth-logs
