The secret weapons of cabbages: Overcome by butterfly coevolution

An international team of researchers has used the power of genomics to reveal the mechanisms of an ancient and ongoing arms-race between butterflies and plants, played out in countless gardens around the world as green caterpillars devour cabbage plants. This study appears 50 years after a classic paper by Drs. Paul Ehrlich and Peter Raven that formally introduced the concept of coevolution using butterflies and plants as primary examples. The present study not only provides striking support for coevolution, but also provides fundamentally new insights into its genetic basis in both groups of organisms.
