If humans evolved from apes ... why didn't the apes evolve ?

This is a joke, right? You're not really so ignorant as to ask this stupid question, are you

Okay. First, humans didn't "evolve from apes". Humans and apes share a common ancestor.

Secondly, there is nothing in the theory of evolution that states that once a new species diverges from an existing species, the older species must die off.
