Evolution

I enjoyed the X-Men comic and cartoon growing up, but then as I got older I thought about the whole evolution thing. Understanding that it's a comic book, I still wonder what the next steps in human evolution would be. I'm hoping that it's something along the lines of only having to sleep 2 hours a day to feel fully refreshed. Or maybe even our bodies use everything we give them, and we only have to go to the bathroom once a week. Imagine all the time that would free up.
