The view that modern humans evolved through a bottleneck from a single founding group of archaic Homo is being challenged by new analyses of contemporary genetic variation. A wide range of middle to late Pleistocene ages for gene genealogies and evidence for early population structures point to a diverse and scattered ancestry associated with a metapopulation history of local extinctions, re-colonization and admixture. A different balance of the same processes has shaped chimpanzee diversity.
