Final answer:
Skin color is an evolutionary adaptation to sunlight availability. Dark-skinned individuals have more melanin to protect from sun damage, while light-skinned individuals can produce more Vitamin D in sunlight-deprived areas.
Step-by-step explanation:
In Biology, if biological traits were concordant, we would expect that people with dark skin would always have...
However, it is important to note that skin color is not solely determined by genetics or inheritance. Skin color is an evolutionary adaptation to the available sunlight in different regions of the world. People with dark skin have more melanin, a pigment that determines skin color, which protects them from the damaging effects of the sun's ultraviolet radiation in sunny locations. Conversely, people with light skin have less melanin, allowing them to produce adequate amounts of Vitamin D in sunlight-deprived areas.
