Neanderthal Scientific  
/ nē-ăndər-thôl′,-tôl′ /
  1. An extinct variety of human that lived throughout Europe and in parts of western Asia and northern Africa during the late Pleistocene Epoch, until about 30,000 years ago. Neanderthals had a stocky build and large skulls with thick eyebrow ridges and big teeth. They usually lived in caves, made flaked stone tools, and were the earliest humans known to bury their dead. Neanderthals were either a subspecies of modern humans (Homo sapiens neanderthalensis) or a separate, closely related species (Homo neanderthalensis). They coexisted with early modern humans (Cro-Magnons) for several thousand years before becoming extinct, but are not generally believed to have interbred with them.

Etymology

Origin of Neanderthal

First recorded in 1860–65; after Neanderthal, valley in Germany, near Düsseldorf, where evidence of Neanderthal man was first found

Explanation

A neanderthal is someone who is rude and not very smart. If your brother interrupts your garden party by spraying your guests with a hose, you can call him a neanderthal. When neanderthal is spelled with a lower-case n, it means a cretin or a dolt — a rough, mean, and slightly foolish person. If you spell it with a capital N, it means an extinct species of human being, and it's the root of the lower-case version. The word Neanderthal is German, named for the Neander Valley where human fossils have been found, and around 1926 neanderthal became popular British slang for a "big, brutish, stupid person."
