Fish help unlock mystery of our skin color
One gene may play big role in making some fish golden, some people white

Zebrafish zipping around an aquarium have led researchers to a gene that may play an important role in human skin color, an attribute that has served as a basis for social discrimination through the ages.

Researchers searching for cancer genes in zebrafish noticed that pigment cells in a peculiar golden variety of zebrafish look like pigment cells from light-skinned humans. This human-fish similarity motivated the researchers to track down the zebrafish gene responsible for the golden hue and lighter-than-usual stripes.

Then the scientists identified the human version of the gene, which has two main types
