|progress? that's funny|
Since the time of our early humanoid ancestors, we've evolved big brains that we can thank for helping us develop languages, space flight, the polio vaccine, and television.
Our evolved ability to walk on 2 legs frees our arms to carry food, water, children, weapons or, of course, a tennis racquet or golf club. We are the only mammals to do this.
These abilities helped our ancestors survive and reproduce, so the related genetic traits have remained in the population - that's natural selection.
While evolution has, on the whole, been good to us, it isn't perfect.
