A LANDMARK STUDY OF THE HUMAN JOURNEY
Where do you really come from? And how did you get to where you live today? DNA studies suggest that all humans today decend from a group of African ancestors who- about 60,000 years ago-began a remakable journey. Follow the journey from them to you, as written in your genes.
Explore your own genetic journey with Dr. Spencer Wells. DNA analysis includes a depiction of your ancient ancestors and an interactive map tracing your genetic lineage around the world and through the ages.

The text illustrates that humans first went out of Africa, their genetic evidences were discovered until today. Thus, the scientist can create the migrations map of them.
