7. Ancestors

Penguins have been around a lot longer than humans.

Their ancestors date back around 70 million years, which is considerably more ancient than human ancestry (less than 2 million years).

The earliest penguin fossil dates back 62 million years, and at that stage they were already flightless, although their wings hadn't yet evolved into flippers.

Penguins are so popular that they've featured in many books and movies, but the real birds are every bit as interesting.

We need to help preserve their habitats and reduce the impact of human activity and climate change on these beautiful birds.

Otherwise we could see them decline and disappear like so many other species.
