The best we can be?

Strange the things I think of at night...evolution is the process whereby an organism adapts to its environment through biological changes to help its chances of survival - the giraffe with its neck, the lion with its fangs.

Human beings went through the same process. We stand straight because it enabled us to walk longer distances. But will we ever need to adapt to our environment anymore? Technology is about changing our environment to suit our needs - creating our own living environments, growing our own food - we change the earth to fit what we need. It is hard to see a situation where we will need to adapt to fit the earth.

Sure there are situations where we can't control the environment - tornadoes, tidal waves. But these are cataclysmic events. Evolution is a response to gradual change. What could change that man couldn't control for?
