Fish Fossil Gives Clues to Evolution

Animal species evolve and adapt over time. This ability to change lays the groundwork for human evolution. Over 375 million years ago an important transition in this lineage occurred - animals living in the sea, began living on land. This complex process happened gradually over generations and an unusual fish fossil found in the Canadian Arctic may help enhance our understanding of this progression.
