Yeah...but in the present political climate, Les, with chimpanzees, gorillas, other apes, and monkeys fighting for equality, dignity, and job opportunity, the word "simian" has taken on a colloquial meaning. In the present vernacular, it does not mean "human", it means other kinds of primates.

It's kind of like the word "Black" which is now universally used for negroid peoples. They are NOT literally black. They are various shades of brown. Nevertheless people choose to call them "black".

You can't get literal about this kind of stuff, you have to understand it in its current cultural context. The words "simian" and "primate" in the present cultural context are interpreted as meaning "not human", but of the ape or monkey species.

To use them otherwise could get you accused of specism. ;-D
