Evolutionary theory has never suggested the possibility of one species changing into another species within a single person's lifetime. It took about 5 millions years for humans to have evolved from an ape. We have to go back to about 24 million years ago before we can find the common ancestor of apes and monkeys. Therefore what you are suggesting is not evolution. It would be closer to divine intervention. Creationists claim that god created the universe and all forms of life in just 6 days. Evolutionary biologists, in contrast, point out that life took 3.2 billion years to evolve from single celled organisms to the wide diversity we see today. Therefore if a monkey suddenly turns into human inside a zoo, it would have to be the work of a divine being, not the result of evolution.

Consider the mirror.

Because humans didn't evolve from modern day monkeys. Humans and chimps evolved from a common ancestor that was neither a chimp nor a human. Technically, both humans and chimps are apes, who share a common ancestor that was also an ape. In the same way, you descended from your grandpa but you are not your grandpa. Both you and your cousin descended from your grandpa but neither of you two are still your grandpa. Actually, think back through 32 generations to your 30th great grandparents. Each of us had over 4 billion 30th great grandparents. That's an astronomical number, and it's pretty safe to say that you look very different from most of them. 32 generations is a long period of time but even if you assume an average of 30 years for each generation (from birth to procreation) that's less than 1000 years. Each of them also had over 4 billion 30th great grandparents going back another 1000 years. When talking about the common ancestor of humans and chimps, 7 million years ago means 7000 segments of 1000 years. The number of "grandparents" you would have going back that far is too big to calculate so it becomes less of a conceptual stretch to imagine that your ancestors that far back were ancient apes with small brains who didn't stand upright. It becomes more obvious that humans share a common ancestor with chimps when you take this into account. The sheer amount of time that has passed since this common ancestor was alive is very difficult to wrap your head around, but it is the thing that makes evolution possible.

It is "how come there aren't monkeys turning into people"

Why should they. Monkeys are supremely adapted to their environment. They aren't going to turn into people anymore than you are going to swing from branches and throw stuff at people.... well on second thought, I guess I don't know you that well.

Considering you clearly do not even understand what evolution is or how it even works I doubt you would understand any answer. Being an atheist has nothing to do with it... just takes someone who actually paid attention in grade school to know how pointless your question is.

If this is just a troll question, try to be a bit more original next time.

If you really believe someone could be born from a rib, then you shouldn't even be asking this question.

Because monkeys are not Pokemon.

I'm not atheist, born again Christian actually. But I just had to say, I love you for asking this lol

One more data point for my upcoming landmark paper: "A Significant Inverse Correlation Between Understanding of Evolution and Mastery of the English Language." r^2 is about -0.99 so far.

-There Are ! Haven't You noticed there are more Christians coming OUT of Zoos- than going In ?! :o

That may not be happening but there a lot of humans turning into jackasses when they go on YA.
