Fish teeth show how ease of innovation enables rapid evolution

It's not what you do, it's how readily you do it. Rapid evolutionary change might have more to do with how easily a key innovation can be gained or lost rather than with the innovation itself, according to new work by biologists at the University of California, Davis, who studied how teeth in certain fishes evolved in response to food sources and habitats.
