- Penguins are weird birds in that they cannot fly and are instead proficient swimmers and divers.
- Evolutionary biologists have long wondered how penguins evolved their peculiar traits and how some of their kind conquered the bitterly cold Antarctic.
- Recent fossil discoveries have enabled researchers to piece together the penguins' evolutionary past, revealing that some of the traits that fortify them against the cold evolved under warm conditions.
- Although penguins have triumphed over 60 million years of climate change, current warming conditions may outpace their ability to adapt.
