This news brief, from February 2006, describes how a mutated zebrafish gene may help us understand human evolution and the genes underlying human skin color. Humans and zebrafish both inherited the same pigmentation gene from their common ancestor.

Correspondence to the Next Generation Science Standards is indicated in parentheses after each relevant concept. See our conceptual framework for details.
- Present-day species evolved from earlier species; the relatedness of organisms is the result of common ancestry.
- There is a fit between organisms and their environments, though not always a perfect fit.
- An organism's features reflect its evolutionary history.
- Similarities among existing organisms (including morphological, developmental, and molecular similarities) reflect common ancestry and provide evidence for evolution.
- Inherited characteristics affect the likelihood of an organism's survival and reproduction.
- Traits that confer an advantage may persist in the population and are called adaptations.
- Scientific knowledge is open to question and revision as we come up with new ideas and discover new evidence.
