Well the question I always ask evo’s is if we evolved from apes, why did we evolve with the immediate need to clothe ourselves. Seriously, if we aren’t bundled up immediately we would die. Makes no sense. The best answer I got was basically, hairless was more sexy, and that’s why we are here. So this argument makes sense inthat respect. Still blatantly false.
We're built for running around central Africa in the heat of the day when any sane animal is looking for shade. Very few other animals have sweat glands over their entire bodies to dump as much heat as we can. Get outside of the 90° weather and we start shivering.
