This may just be the one of the biggest piles of offal that ichie has ever posted here. The most striking difference between human teeth and ape teeth is the same difference as between human teeth and cannine teeth: Human teeth are distributed in a parabolic arch, which allows for the various intonations of intelligent speach, while ape and dog teeth are located in parallel jaws.
I posted that, not ichy .. I got it from a college website, so it must be a highly educated statement, and not ignorant like all of mine are.
"speach"? :-)
