OP: How did the leopard get its spots? How did the zebra get its stripes?
The answer may be a gene, which scientists have found governs colour patterns in deer mice, the most widespread mammal in North America.
This gene, called Agouti, is found in all vertebrates and may establish colour pattern in a wide variety of species, a process that has been poorly understood at both the molecular and the evolutionary level.
Dakotat5: if it were the gene alone and if evolution were true then everyone would have spots.
