If we did come from chimps, chimps came from crocs, which came from fish.

But, for some reason, I'm don't think that we came from chimps. I heard of a commonly thought of ancestor, of Ours, being discovered that it was not in our past.

Hypothesis #1: Chimps are not our ancestors.

I'm basing that decision on the fact that we're talking about chimps and I can't think of another species that might fit that criteria.

Yeah, I just saw one, and came to the conclusion that I'm nuts.
