Recent advances in the study of human origins have increased our understanding of our ancestors. There have been new, major fossil finds. WT 17000, a 2.5 million-year-old robust Australopithecus found in Kenya (Walker et al. 1986), led to a revision of early hominid phylogeny (Delson 1986; 1987). Existing fossil materials have been reassessed. For example, Tattersall (1986) maintains that at least two unrecog- nized hominid species (Homo neanderthalensis, H. hei delbergensis and possibly H. steinheimensis ) existed be tween the times of H . erectus and fully modern H . sapiens.
