Question

Quizplus · Accepted Answer

While skin color is influenced by both genetics and environment (such as sun exposure), it is not solely determined by one's genes. Instead, populations that face similar environmental challenges (such as high levels of UV radiation) may develop similar skin pigmentation through natural selection. This means that a biological similarity such as skin color can indicate both shared ancestry and adaptation to similar environmental pressures.
