Received wisdom that modern humans emerged in Africa then dispersed across the rest of the globe is being challenged by skulls found in Dmanisi, a site in Georgia to the south of Russia.Analysis of the skulls suggests that instead, small numbers of very early ancestors of modern-day humans may have migrated to Europe, where they evolved into Homo erectus, the immediate predecessor of modern Homo sapiens.Then, Homo erectus filed back into Africa before eventually making the crucial transition to Homo sapiens.
