"This computerized reconstruction of a Neanderthal child's skull and face was generated by computer scientists at the University of Zurich by using computer graphics newly developed for this purpose."
The page also says, "There is just as much physiological difference between existing groups of Homo sapiens sapiens as between Neanderthal and non-Neanderthal human bones."
Wikipedia says: "The Inheritors (1955) shows "new people" (generally identified with Homo sapiens sapiens), triumphing over a gentler race (generally identified with Neanderthals) by deceit and violence."
This is interesting because common ideas about Neanderthals don't portray them as a gentler race conquered through deceit and violence. From the page linked above, "The popular image of Neanderthals as clumsy, backward creatures has been dealt another blow."
Wikipedia reports: "Around 1–4% of the modern Eurasian genome derives from Neanderthals, and about 20% of the Neanderthal genome survives today."
