How can have east asians evolve in colder climates if they have such lil body hair?
A doctor has provided 1 answer
They had clothes: Our ancestors came out Africa around 100,000 years ago able to make their own clothes. This made possible settlement of cooler parts of the world. Abundant body hair on men isn't for staying warm, it's to advertise being a grown, virile man -- and the genes still vary. You can read about the evolutionary origin of secondary sexual characteristic in any good bio book starting with Darwin's.
