Neanderthals or Neandertals UK /niˈændərˌtɑːl/, us also /neɪ/-, -/ˈɑːndər/-, -/ˌtɔːl/, -/ˌθɔːl/) (named for the Neandertal in Germany) were a species or subspecies of archaic human, in the genus Homo, which became extinct around 40,000 years ago. They were closely related to modern humans, sharing 99.7% of DNA. Remains left by Neanderthals include bone and stone tools, which are found in Eurasia, from Western Europe to Central and Northern Asia. Neanderthals are generally classified by paleontologists as the species Homo neanderthalensis, having separated from the Homo sapiens lineage 600,000 years ago, or alternatively, as a subspecies of Homo sapiens (Homo sapiens neanderthalensis).
