Climate change and evolution.
A few weeks ago, I saw a Nova episode about how there's strong evidence that humanity's ancestors were forced out of the trees and onto the plains by climate change. About how we owe a climate changing over a geological timescale (thousands of years) to our evolution.
Now I look at how the climate is changing again, within a single human lifetime, and I'm not worried for humanity. We're adaptable enough to survive. Millions may die, and civilization may collapse, but we will survive. Life won't look the same, but we will survive.
Still, it makes me wonder if we'll evolve again in response to it, or if civilization's collapse will let things go back to normal.
