How do you imagine the world millions of years from now?

Uh, a million years isn't that long in evolutionary time.

True enough, but it only took 2 million years for homo erectus to evolve into sapiens. That's a significant change, and it took place in a relatively static environment: Earth. Add to that the fact that future evolutionary changes might be adaptations to an extraplanetary environment, like a Martian space colony, and the process may occur faster. It's reasonable to expect some significant changes in the appearance of our ancestors if they evolve to adapt to, say, the gravity on Mars.

If we get our political and economic acts together and support science so we learn how to jump hyperspace to get to other planets, that would be way cool.

We'd have to jump or hundreds of generations would spend their entire life time in a space ship. I need to Google and find out how Neil Armstrong and company dealt with cabin fever on their way to the moon. Sorry, I'm just so practical.
