The caveman is a stock character representative of primitive humans in the Paleolithic. The popularization of the type dates to the early 20th century, when Neanderthals were influentially described as "simian" or "ape-like" by Marcellin Boule and Arthur Keith.

Neanderthals are an extinct group of archaic humans who lived in Eurasia until about 40,000 years ago. The type specimen, Neanderthal 1, was found in 1856 in the Neander Valley in present-day Germany.
