I'm glad you asked, because your question reveals that your teachers have done a real job of professional malpractice in teaching you. Evolution isn't "taking us" anywhere. It's a description of how populations change over time. The population changes because individuals (some of whom have mutated genes) either die without offspring (thus taking their genes out of the pool) or they survive long enough to spawn a new generation (thus keeping their genes in the pool). That's it. That's the whole ball of wax. Over time, we get the world of various species that we see -- including us. We, however, are intelligent to decide for ourselves where we're going, so the evolution process is going to be radically different where we're concerned.
