Document Summary
More recent discoveries like the turkana boy discovered in kenya in the mid-1980s and dated to about 1. 6 million years ago have led some paleoanthropologists to argue that. African and asian homo erectus should be placed into two separate species with. African species placed in the species homo ergaster. The taxonomic splitting is argued on the basis of cranial differences. Where such a split is made homo ergaster is generally positioned as ancestral to modern humans while homo erectus is seen as an extinct relative: not directly ancestral to modern humans. Archaic homo sapiens or homo heidelbergensis: big brains, big faces. Fossils that date from 130 000 to 700 000 years ago are not considered to still represent. Fossils from this time still retain some homo erectus features: large brow ridges, sloping foreheads and relatively flat crania, large prognathic faces. They also resemble modern homo sapiens in some respects: large average cranial capacity, relatively small teeth.
