New Clues How Neanderthal Genes Affect Your Health
Speaking of the fossil record, what about the linguistic fossil record? The word Neanderthal is a compound German word: Neander + thal. "Neander" is the name of a river in Germany and "thal" means valley. But not any more. Modern German dropped the "th" spelling (and the "th" sound) [ed.: nice alliteration].
Neandertal is the modern German word. There's even a bit of linguistic residue in English: Tal is cognate with "dale" as in hill and dale.
