The study could also provide clues to other evolutionary conundrums, such as how snakes lost their limbs. And it might yield some potential answers to medical questions, say the researchers.

"Dissecting the molecular basis of the naturally occurring variation generated by evolution can lead to discoveries of new mechanisms of embryonic development, some of which are totally unexpected.
