PRIMATES FIGURE NO. 24 MAN'S GENEALOGICAL TREE (By kind permission of Sir Arthur Keith and Messrs. Williams & Nor gate, publishers) From a generalized "Primate" stem there were separated off first, the New World Monkeys; second, the Old World Monkeys; third, the smaller Anthropoid Apes; fourth, the larger Anthropoid Apes. From a generalized Humanoid stem there were separated off various 'tentative men/ like Pithecanthropus. From the stem of Homo there was separated Neanderthal man (Homo neander- thalensis) ; the line is continued by Homo sapiens. The estimates for the duration of Eocene, Oligocene, etc., are of course approxi- mate and subject to criticism. 208
