In a literal story with legs, the discovery of a new arctic fossil is said to fill an evolutionary gap between fish and limbed animals. The 375-million-year-old fossils indicate that the new species has a skull, neck, ribs, and part of a fin like the earliest limbed animals, but also has fins and scales like a fish. Larry speaks with Dr. Ted Daeschler, co-leader of the expedition to Ellesmere Island, to learn more about the exciting finding.
