true / false.

False

Explanation:

Humans all around the world has a body temperature similar, humans like all the mammals are endothermic (the body temperature is regulated for itself) animals, this means that our temperature doesn't change according to the climate.

So it's false that human evolved in colder have more blood flowing into their extremities, and at a hotter temperature, than people living in warmer climates.
