Evolution: Biology's next top model?, Nature
 









Excerpt: As the water temperatures plunged by about 5 °C to below zero over the
next few million years, most fish became extinct or moved on to warmer climes.
But one group, the Notothenioidei, remained. Thanks to some extraordinary
evolutionary innovations, these bottom-dwellers radiated, speciated and
ultimately dominated. Crucial proteins shifted shape so they could work at cold
temperatures, and a digestive enzyme fragment took on a new role as antifreeze.
