ABSTRACT
T He Concepts And Methods on which the classification of hominid taxa is based do not differ in principle from those used for other zoological taxa. Indeed, the classification of living human populations or of samples of fossil hominids is a branch of animal taxonomy. It can only lead to confusion if different standards and terminologies are adopted in the two fields. The reasons for the adoption of a single, uniform language for both fields, and the nature of this language, have been excellently stated by G. G. Simpson in his contribution to this volume.
