Today, six billion people are spread across the planet, but there was a time
when the human species numbered only a few thousand and the world was a
single continent: Africa. Then a small group left their homeland on a
journey into an unknown, hostile world. In this special, geneticist Dr.
Spencer Wells travels to every continent in search of those whose DNA holds
the traveler's secret history.
