A new genetic and fossil analysis of penguins reveals how they evolved.
Penguins are perhaps best known for being flightless birds whose wings help them"fly" through frigid Antarctic waters. But penguins lost their ability to fly and instead became streamlined swimmers some 60 million years ago, long before the Antarctic ice sheet formed — and researchers have now revealed how that happened.
"These early ones are probably evolving from a puffin-like animal that could still fly through the air," Ksepka said. "It doesn’t affect all species equally, but it’s almost like someone is turning a crank to make more penguin species," Ksepka said.
