Earlier this month I asked this question on my blog to see if anyone would be able to answer it. One person wrote and guessed that humans evolved smart enough to preserve monkeys, and that this was a rare instance. But that’s not the answer.
The answer is simple enough: humans didn’t evolve from monkeys!
So yes, this was a trick question, and it took me 30 seconds to realize that.
Humans and monkeys shared a common ancestor as they are both hominids. That doesn’t mean they evolved from each other. It’s like saying “if I evolved from my cousins, then why are my cousins here?”
