Thought I'd check out to see how far science has gone... It's quite impressive!!!
" In January of this year a region of the brain called the planum temporale, thought only to be present in humans, was found in chimpanzees (Science vol. 279). It is involved in the comprehension of language in humans. Chimpanzee communication is dominated by gesture so it maybe that the planum temporale is important in gesture recognition in these animals. If the appropriate gear is present in other primates perhaps their language abilities are more advanced than we think.
Did language evolve because we had something to say or do we have something to say as a result of language? The origins of human-like vocal ability have recently been traced back as far as the Neanderthal. The hypoglossal canal, which carries a nerve that controls the flexibility of the tongue, is very similar in size in both Homo sapiens and Neanderthals, but much smaller in apes (Proceedings of National Academy of Sciences). Apes canít talk because they lack this motor ability?They may well have the intention but not the capability because of their anatomy. "
