The dainty veins gracing the wings of dragonflies and other insects are like fingerprints: Each wing displays a distinct pattern. A randomized mathematical process may help explain how certain thin ...

Heliconius charithonia is one of the species of butterflies whose wing patterns scientists scrutinized to better understand the evolutionary process. This butterfly is wild-type; the genetically ...

Many butterflies develop wing patterns that mimic other species to protect themselves from predators. While growing complex body parts like wings involves many genes, the difference between two ...

Organisms have evolved endless morphological, physiological, and behavioral novel traits during the course of evolution. Novel traits were proposed to evolve mainly by orchestration of preexisting ...

A painstaking study of wing morphology shows both the striking uniformity of individuals in a species and a subtle pattern of linked variations that evolution can exploit. Two years ago, to prepare ...

Many dragonflies zip through the air with their translucent wings painted in an array of dark spots and bands. But — for males at least — those dapper decorations could soon fall out of style as a ...
