| Popis: | Middle Pleistocene erectus skulls differ from ours in fifteen discrete traits, primary among which are their smaller cranial capacities, flatter and more strongly constructed braincases, larger and more anteriorly projecting faces, and inflected mastoid processes. Back to 40,000 years ago all fossil hominids are of the sapiens desing, while all those clearly older show the erectus pattern. Except for their large brains, Neandertals are of the erectus type. The sapiens differences (many of them mal-adaptive in themselves) follow directly, for biomechanical reasons, from an elongation of the pharynx and indicate full development of speech as the delivery system for laguage. The archeological record at the same time showns a worldwide change of increased tool complexity, geographical localization of desings, and increased rate of change. Faster and easier transmission of information by the vocal medium would increase culture content and would facilitate building flexible social organizations. The final step ... |
