Information on the order of eruption of the permanent teeth in fossil hominids, unlike that on the living anthropoids and recent Europeans, is rather scanty and most of this data is scattered through the literature. Although it is true that in some of the more recent publications mention is made of the eruption of permanent teeth in the known forms of fossil hominids in general, in most cases these references are only brief. In view of this I have considered it worthwhile to review the literature on this subject to see what is defmitely known about the order of eruption of the permanent teeth in the fossil hominids and to what extent they resemble the anthropoid apes and diller from the modern Europeans.
