Biologists have found that a simple interaction between just two genes determines the patterns of fur coloration that camouflage mice against their background, protecting them from many predators. The ...

How the leopard got its spots and the zebra its stripes might not be just-so stories much longer. Biologists are beginning to pinpoint the molecular mechanisms animals use to deck themselves out with ...

Scientists are moving closer to answering some age-old questions. How did the leopard get its spots? How did the zebra get its stripes? The answer may be a gene called Agouti, which the scientists ...

Reef fish in different oceans often develop similar color patterns because evolution explores the same set of biological ...
