Zebras and tigers have stripes, cheetahs and leopards have spots, and the ocellated lizard (Timon lepidus) boasts a labyrinthine pattern of black-and-green chains of scales. Now researchers from the ...

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 ...

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 ...

In our newly published research in Science Advances, my student Ben Alessio and I propose a potential mechanism explaining how these distinctive patterns form—that could potentially be applied to ...

The colors and patterns of black swallowtails reveal the diversity of evolutionary dynamics acting on the sexes and the various life-history stages Six species of swallowtail butterflies occur locally ...
