Quizplus · Accepted Answer

The genetic alteration that is linked to the evolution of skin tone is the production of melanin pigment. Melanin protects the skin from the harmful effects of ultraviolet radiation from the sun by absorbing and dissipating the radiation. Additionally, melanin production is important for the body's production of vitamin D, which is essential for calcium absorption and bone health. Therefore, the process of natural selection has favored individuals with higher levels of melanin production in regions with high levels of ultraviolet radiation.
