I can see species evolving, and would never deny that it’s a natural process.
I guess the question is “If we evolved from monkeys, why are monkeys still around?” These are not terms I would use, but ones I have seen used before.
I think I can estimate a reason, but I’m no governing body.
I guess to parse it down, the question would be “If humans were derived from another species, why would that species still exist un-evolved?”
What are the prevailing theories here?
