The only true ignorance here is that humans think that they are not bipedal primates.
We are just another form of Ape, so I don`t see how this can be in any way offensive unless you are totally a moron when it comes to Evolution or you are a bible thumper like Coach.
Hmmm.
If humans involved from apes, why is it that presently there are no apes still evolving into humans?
What? Was it one in a gazillion ape that just happened to become this highly developed animal called man, homosapien (whatever you want to call it)?
Is it because of changes in climate, nature, etc?
And if man is just an evolved beast how did he develope conscience, self awareness, logic and reason, ability to come up with so many different languages?
