    Archaeological Science: Our Teeth Tell (Migration) Tales.

    Archaeologists reconstruct the past in multiple ways, using novel scientific techniques, historic records, oral traditions, and artifacts. Drs. O’Donnell and Freiwald talk about their research on ancient migration in northern New Mexico and today’s Mexico City 800 years ago using the biological and chemical differences in human teeth. Who were migrants in Tlalnepantla, Mexico? What happened to the Gallina people in northern New Mexico when their homes were abandoned? Dental morphology and isotopic analysis are key forensic techniques that answer questions posed by historical records and oral traditions.
