I had assumed that modern, comfortable living meant that human beings were done with substantial evolution. Turns out, I might have been wrong:
Until recently, anthropologists believed that evolutionary pressure on humans eased after the transition to a more stable agrarian lifestyle. But in the last few years, they realized the opposite was true -- diseases swept through societies in which large groups lived in close quarters for a long time. Altogether, the recent genetic changes account for 7% of the human genome, according to the study published in the Proceedings of the National Academy of Sciences.
Here's hoping it holds for modern societies as well.
