- By hopping, today’s kangaroos can scoot swiftly through the countryside. That was not true for some of their ancient cousins. True giants, those now-extinct kangaroos would have walked on two feet — and relied on their tippy-toes.
- When this modern ‘walking’ fish was raised on land, its body changed. How it adapted resembles some prehistoric fish. These alterations hint at evolutionary changes that may have made life on land possible.

- The giant, Burmese pythons living in Florida’s Everglades like their adopted home. And new research shows they can find their way back to it if people try to move them somewhere else. Not all snakes will do this.
