@platorepublic,
there is a good chance, if you believe in evolution. after all, we are believed to have evolved from monkeys or apes, but instead of growing a tail, or retractable claws, or anything neato like that, our brains are growing, and the rest of our body is kind of becoming more effictient. technology has removed any need to grow gills (scuba tanks) wings (planes) sharp teeth, (forks and knives and flame) extra hair (heat, clothes, jackets), and soon, all we will need are vital organs, and a way to protect them. (robotic exoskeleton).
