Two Antarctic penguin genomes reveal insights into their evolutionary history and molecular changes related to the Antarctic environment
Background Penguins are flightless aquatic birds widely distributed in the Southern Hemisphere. The distinctive morphological and physiological features of penguins allow them to live an aquatic life, and some of them have successfully adapted to the hostile environments in Antarctica. To study the...
