        Island Biodiversity: Tracking Human Influences | Smithsonian Science How

        Analyze archaeological evidence of human life on islands and coasts. Meet Dr. Torben Rick, an archaeologist at the National Museum of Natural History. Look back over thousands of years of influence of humans on the California Channel Islands and the Chesapeake Bay. See how changing environmental conditions interacted with human lifestyles to shape the biodiversity of the islands. Follow Torrey as he uses radiocarbon-dating of bones and DNA analysis to tackle elusive questions such as how foxes arrived in the Channel Islands. Find out how archaeological information helps manage island ecosystems today.
