Neanderthals with modern humans. Artwork showing interactions between Neanderthals and early modern humans (Homo sapiens sapiens). The early modern humans are Cro-Magnons,dating to around 35,000 years ago. Neanderthals were shorter and more heavily built than modern humans,who are taller and slenderer. Neanderthals (Homo neanderthalensis) first appeared in Europe around 600,000 years ago,and co-existed with modern humans,who emerged around 200,000 years ago. It is thought that Neanderthals and modern humans interbred,and by around 30,000 years ago no Neanderthal traits remained |
