Abstract

The humerus of the Sinanthropus is already known as having the narrow deltoid tuberosity with two crests. The present study shows that these characters can also be seen among the European "classic" Neanderthals and that the deltoid tuberosity of the West Asian Neanderthals, such as Amud I, Shanidar I and Skhul IV, also represents two crests but is wider than that of the "classic" Neanderthals and slightly narrower than that of the resent West Asian Lebanese, the latter has three crests in most cases. The narrowness of the tuberosity in the Sinanthropus and the Neanderthal seems to be a character-istic from the evolutional viewpoint. The features of the deltoid tuberosity in the West Asian Neanderthal may approach to that of the Sapiens.
