To the OP, on why certain species have not evolved in a very, very long time:
If a species, such as an ant, is as lethal and efficient as it can possibly be, or even close, there will be no noticeable evolution until something else evolves sufficiently and in such a way as to threaten it and cause another trait to be desirable instead of what already exists. I'm well aware of the difference between micro and macro evolution, by the way.
It's clear that while you grasp the basics of evolution, you have not researched (or at least not comprehended :/ ) the more advanced ways in which it functions, such as group selection.
