The Human Family Tree - Naked Science - National Geographic ChannelOn the most diverse street in the most diverse city in the most diverse country in the world, a team of National Geographic scientists will swab the cheeks of some 200 random New Yorkers. The goal: to retrace our ancestral footprints and prove we are all cousins in the "family of man." Join geneticist Spencer Wells and a team of technicians from National Geographics Genographic Project as they trace the human journey through time and space, 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 -- will help paint a picture of these amazing journeys. Ultimately, The Human Family Tree answers some of humanitys most burning questions, such as 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.
