a family of the order Primates. This family includes modern and fossil (Archanthropus, Palaeoan-thropus) man. Most scientists also include Australopithecines and other biped fossils of the higher primates in the family Hominidae. However, there are researchers who take Hominidae to mean only “genuine” man, starting from Archanthropus. According to the first point of view, the family Hominidae arose toward the end of the Tertiary period (about 3.5 million years ago); according to the second, it arose toward the middle of the Quaternary period (that is, about 1 million years ago).
