Relating to or belonging to or resembling Neanderthal man; Also called: Neanderthalian, Neandertal.

Hominid of the Mid-Late Paleolithic, named for the Neander Thal (valley) near Düsseldorf, Germany, where a skeleton was found 1856. Homo sapiens neanderthalensis lived from about 150,000 to 35,000 years ago and was similar in build to present-day people, but slightly smaller, stockier, and heavier-featured with a strong jaw and prominent brow ridges on a sloping forehead. The condition of the Neanderthal teeth that have been found suggests that they were used as clamps for holding objects with the hands.
Recent evidence suggests their physical capacity for the sounds of speech. They were replaced throughout Europe by, or possibly interbred with, Homo sapiens sapiens.

Uncouth person.
