text: among the variety of humans, are there any different species? if another meaning for race is actually "sub-species", then does that mean that there are many kinds of homo sapiens sapiens? no.  we're all homo sapien sapiens. (and no, that's not a typo)  >>>what would stop the republicans from trying to put it on the  >>>endangered species list  i expect the members of that species would.  why just republicans?  just wondering since they tend not to be so big on environmental issues...  ____________ carter, fyi the biological species concept definition of a species (the one you attempted to apply to humans) isn't actually used anywhere outside of a high school classroom.  lions and tigers and interbreed (and produce fertile offspring), as can wolves and cyotes.  however, i don't think anyone would argue that lions and tigers are the same species.  you've arrived at the correct conclusion, but for the wrong reasons.  oh, and homo sapien is two words, although the proper name for modern humans is actually homo sapien sapien.  _________ >>>"put it on the endangered species list" as in, genocide,   what???  that doesn't make sense.  the endangered species list is a list of species we're protecting, not species we're trying to eliminate.  putting a species on the endangered species list make it illegal to kill members of that species under most circumstances.  to answer you question about genocide, however, what stops genocide now?  i don't see where it would be any different if we were talking about a group that is officially a separate species.  although, species being driven to extinction or "exterminated" is usually look upon as a *bad* thing, so i don't see where their being a separate species is an inherent justification for genocide, although i think it would be human nature to use it as such.   _______ thanks for pointing that out, calimecita, i went back and capitalized the genus names.   i wasn't entirely awake when i wrote that :-p
