the ancestors of bald eagles have lived on Earth for eons. Evolutionary biologists believe that birds evolved from reptiles. From their skeletal structure to their blood cells.
The descendants of Dorudon went on to evolve into modern whales. About 34 million years ago, a group of whales began to develop a new way of eating.These are called baleen whales, which include blue whales and humpback whales.
The polar bear has evolved over time from the common brown bear by changing its fur colour to white, the ideal colour to blend in with its ice-covered surroundings.
Chipmunks are part of the squirrel family, and split off from mice and rats about 70 million years ago. Scientists think they probably evolved their stripes independently.
