how neanderthals disappeared
Coyne writes that "what really happened to [neanderthals] is arguably the biggest unknown about human evolution" (206). The two main theories are that neanderthals simply evolved into other species in all the areas it had inhabited, or that homo sapiens had migrated out of Africa and out-competed neanderthals into extinction world-wide. Based on the traces that evolution leaves and speciation in geographically separated areas, which theory on the extinction of neanderthals is more likely to have occurred? Could it have been a combination of both theories?
