I have a question for you: Are we witnessing the end of humanevolution? At first glance, it might sound dramatic. But think about it. Physiologically, evolution leaves tracesbehind.

• Some people can still wiggle their ears—uselessnow, but once a survival tool.
• Our coccyx? A remnant of a tail we no longer need.

So shouldn’t our mental models evolve, too? And yet, we still say “the sun is rising” when we’ve known for centuries that the sun doesn’t move—we do.
