Yeah, so? What did you think you were "disproving" by pointing this out? Our ancestors *were* apes.
The only things that apes produce are other apes.
There's a flaw in your "logic": You Are An Ape.
Then when you're done reading that, read this post I wrote in response to someone else's similar claim.
Then check out this post of mine covering just a tiny sliver of the vast mountains of evidence for ape/human common ancestry.
I regret to inform you that biology is not nearly as simplistic and restricted as your conception of it.
I'll stack my graduate and post graduate gradepoint, as well as my IQ against yours any day.
