After carefully watching the video, choose THE BEST Claim in regards to why human skin color varies throughout the world. Primates have light skin color under their dark hair so when humans began to evolve and lose body hair, that pigment needed to go into their skin so they could still blend in with their surroundings. Darker melanin is beneficial for reproduction in areas where ultraviolet (UV) light is high, and can negatively affect reproduction in areas of low UV light. Darker melanin is beneficial under intense UV light because it protects from skin cancer, absorbing the UV light. Under low UV light, producing excess melanin uses too much energy, therefore it is more beneficial (energy saving) to produce less melanin in low UV light areas. Humans evolved as separate populations, around the equator and towards the poles, so skin pigment color (melanin) was naturally different in those areas.
