National Geographic: The Human Family Tree ( 2009 ) ( National Geographic (Video) (DVD)

On the most diverse street in the most diverse city in the most diverse country in the world, a team of National Geographic scientists swab the cheeks of some 200 random New Yorkers-hoping to reveal clues about our ancestral footprints and prove we are all cousins in the "family of man." Join geneticist Spencer Wells and a team from National Geographic's Genographic Project as they trace the human journey through time, from our origins in the heart of Africa to the ends of the world. Cutting edge science, coupled with a cast of New Yorkers-each with their own unique genetic history-helps paint a picture of these amazing journeys. The Human Family Tree answers some of humanity's most burning questions-who we are and where we come from-and forces us to change how we think not only about our relationships with our neighbors, but ourselves.
