Keith, Arthur

British anatomist and teacher, conservator at the Hunterian Museum. Remembered for his errors concerning the Piltdown fragments, Keith was nevertheless a capable mentor to a generation of British anatomists and a popularizer of human antiquities. Postulated a cerebral Rubicon of 750 cm3 below which no hominid would fall. With American T. D. McCown, proposed the preneandertal hypothesis of human origins, lumping the Levantine specimens into a heterogenous Neandertalian group. Author of A New Theory of Human Evolution (1948).
