This past May, working with nearly 90 co-authors from six continents, he published the results of a massive global study of butterfly evolution, based on DNA samples from 2,300 butterfly species.

Butterfly and moth wing color variations, long attributed to the cortex gene, are actually controlled by a microRNA, mir-193, which represses pigmentation genes. This discovery, conserved across ...

Many of these wing color pattern variants are textbook examples of natural selection and evolution ... colors in the African squinting bush brown butterfly, Bicyclus anynana, the Indian cabbage ...
