The hidden history found in your teeth | Carolyn Freiwald

Visit to get our entire library of TED Talks, transcripts, translations, personalized talk recommendations and more. Your teeth carry secrets: centuries of history about your ancestors, from where they lived to what they ate and where they traveled. Bioarchaeologist Carolyn Freiwald traces the story of human migration across the Americas — from Mayan royalty and Belizean buccaneers to rural Appalachian farmers — to illustrate what ancient teeth can reveal about you. The TED Talks channel features the best talks and performances from the TED Conference, where the world's leading thinkers and doers give the talk of their lives in 18 minutes (or less).
