Penguins May Face Extinction in Future Amid Modern Climate Change

Penguins have the slowest known rate of evolution among birds, and they might not be able to handle modern climate change, which is occurring more rapidly than past change.

Early penguins quickly adapted to marine life in the Southern Hemisphere after a mass extinction event around 66 million years ago. From there, their evolution continued in spurts in response to periods of climate change, such as at the start of the most recent ice age.
