Latif Nasser: Discovery in the Arctic - Clip

In this excerpt from the PBS special TED Talks: Science and Wonder, Radiolab's Latif Nasser takes us across the frozen Arctic with a paleobiologist who makes a rather remarkable discovery. Finding 3.5 million year old bones preserved in the ice, the scientist uses a new process called "collagen fingerprinting" to determine the ancient find was a long way from its current home.
