Caveman

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. The term "caveman" has its taxonomic equivalent in the now-obsolete binomial classification of Homo troglodytes (Linnaeus, 1758).
