from fully replacing the workers at AT&T. :) - gLeN

anatomy is different? But my question is: is the difference great enough
to prevent the chimp from speaking? Gerry 2/13/99

>> Gerry, there are a lot of differences in oral anatomy between humans &
chimps, eg, humans have everted lips, a smaller mouth, less prognathism, a
highly vaulted palate, a smooth palate vault, a round tongue, a descended os
hyoid & larynx. Moreover, the cerebral control in humans is about twice that
in chimps (area 4) and the coordination of area 4 by the prefrontal areas is
much better developed in humans (eg, area 44 or Broca). Yes, these
differences are great enough to prevent them from speaking. Marc

>Thanks Marc. That's the explanation I was looking for. And it was so
succinctly worded as well. So although chimps can be taught wrote tasks,
the chimp will never speak a "Nostratic" language. Correct? Gerry

Correct.
