Modern Humans Did Not Admix with Neanderthals during Their Range Expansion into Europe

PLoS Biology: Modern Humans Did Not Admix with Neanderthals during Their Range Expansion into Europe: "The 'Neanderthals' or Homo sapiens neanderthalensis (HN) constitute a group of hominids, whose particular morphology developed in Europe during the last 350,000 y under the effect of selection and genetic drift, reaching its final form approximately 130,000 y ago (Klein 2003). This subgroup of hominids populated Europe and western Asia until the arrival of the first modern humans, Homo sapiens sapiens (HS), approximately 45,000 y ago (Mellars 1992). This arrival coincided with the beginning of Neanderthal decline, a process that occurred in less than 15,000 y and that is still not fully understood (Stringer and Davies 2001). "
