Newly named Nora, the polar bear cub at the Columbus Zoo and Aquarium, plays with a Kong frisbee, just like your dog. That basically means you can take her home, right? That is, if you can handle the cuteness.
When did the polar bear become the polar bear?
More than 4 million years ago, according to new findings reported in the Proceedings of the National Academy of Science journal.
Previously studies had reported the polar bear split from ancient grizzly bears within in the last 600,000 years.
The study also shows that the number of polar bears has been on the decline for at least 500,000 years.
