In this activity, students explore how experimental work in zebrafish led to a better understanding of the role of the gene SLC24A5 in human skin color. The activity complements the film The Biology of Skin Color.
A number of interactive questions are embedded within the short film The Biology of Skin Color, which explores the hypothesis that the variations in skin color in humans arose as adaptations to the intensity of ultraviolet radiation in different parts of the world.
This activity explores the evidence that differences in human skin color are adaptations to varying intensity of UV light, as discussed in the short film The Biology of Skin Color.
