TED-ED: The science of skin color - Angela Koine Flynn

The video explores how skin color varies due to melanin, a pigment produced by melanocytes. It explains the evolutionary process that led to diverse skin tones, driven by sun exposure and migration. Melanin protects against UV damage, while lighter skin tones evolved to absorb more UV for vitamin D production. This adaptation helped humans survive in different environments, leading to a wide range of skin colors today.

Explain the relationship between UV exposure and vitamin D production in humans.

In what ways did skin color adaptation contribute to human survival in different environments?
