Based on what you know about skin pigmentation so far, suggest a mechanism by which UV intensity could provide a selective pressure on the evolution of human skin color. In other words, propose a hypothesis that links skin color to evolutionary fitness.

Respuesta :

Answer:

More darker skins are more resistant to disease than lighter skins.

Explanation:

  • The skin color pigmentation is based on the genetic makeup that is biological factors and physiological factors such as solar insolation, heat humidity, and temperature. The human's skin color ranges from dark brown to lighter hues.
  • The people who live near the tropics are much darker occurs due to the pigmentation of skin as compared to those that live near the arctic. The presence of melanocytes in the skin cells helps in deterring fitness and evolutionary traits.
