The Human Family Tree

A volunteer swabs her cheek for DNA sample to participate in National Geographic's Genographic Project. Her DNA will be used for a five-year research partnership led by Dr. Spencer Wells, renowned international scientists, and IBM researchers.  The Genographic Project aims to sample the DNA of more than 100,000 indigenous people from around the world, with the ultimate goal of charting new knowledge about the migratory history of the human species.
Narrated by Kevin Bacon, The Human Family Tree travels to one of the most diverse corners of the world -- Queens, N.Y. -- to demonstrate how we all share common ancestors who embarked on very different journeys.
