Caucasians do not need the complex narrow nasal system to survive in very cold conditions such as ice ages. Black people live happily in Alaska when their facial structure is designed to breath in the thin air of a hot climate, again not really needed. Black skin is good protection from the damaging rays of the sun. However, mainly white older adults die of skin cancer in Australia not younger people in the prime of species reproduction.
