The Adventurers Episode 4 of 4: The Lost People of the Baja

Canadian paleo-pathologist Eldon Molto is leading the search for clues of the mysterious Pericu people of Baja California, Mexico - a fierce, independent tribe that disappeared over a century ago, after being exposed to European disease. They left virtually nothing behind but their bones. But by using DNA, Molto is piecing together the story of the Pericu and along the way makes a surprising discovery that raises questions about identity and our own existence.
