ok, the faux science part was off, my apologies. I actually meant that the whole "we have teeth like that" is kind of a weird argument, seeing as how we defy "nature" the whole time. You want to take into consideration teeth? fine. Don't ever take a plane, you weren't meant to do that since you've obviously don't have wings. Don't use medicine either. Hell, don't use tools and go sit in a cave.
(O/T: wth is it with the quoting lately?)
