A single gene, doublesex, controls wing mimicry in butterflies
A single gene regulates the complex wing patterns, colors and structures required for mimicry in swallowtail butterflies, report scientists from the University of Chicago, March 5 in Nature. Surprisingly, the gene described, doublesex, is already well-known for its critical role in sexual differentiation in insects.

New fins evolve repeatedly in teleost fishes
Though present in more than 6,000 living species of fish, the adipose fin, a small appendage that lies between the dorsal fin and tail, has no clear function and is thought to be vestigial. However, a new study analyzing their origins finds that these fins arose repeatedly and independently in multiple species.
