genus of extinct primates, 1895, from Modern Latin, literally "monkey-man," from Greek pithekos "ape" (see pitheco-) + anthropos "man" (see anthropo-). Coined 1868 by Haeckel as a name for a hypothetical link between apes and men (attested in English in this sense from 1876); applied by Dr. Eugène Dubois (1858-1940), physician of the Dutch army in Java, to remains he found there in 1891.
