Evolution in the sense of natural selection is an incredibly brutal, dumb, and silly subtractive process. I urge my fellow hn commenters not to mistake this for some higher purpose or value. Its an easy mistake to make but the selection pressures that would leave some survivors of the Holocene implies no higher, better intelligence. Often it involves greedy local optimization. Roaches and rats for example are well suited to survive and although clever and resourceful they aren't exactly what might be thought of something that might lead to uberintelligence or something better than our evolutionary path.
