How are the DNA Tribes world regions defined?
DNA Tribes is the only genetic ancestry analysis that identifies world regions based on mathematical patterns of unique genetic variation. Other tests rely on non-scientific racial divisions. These presumed racial groupings present an incorrect and incomplete view of genetic patterns actually present in the world. Simplistic divisions of the world into 3-5 continents ignores important unique regions that do not neatly fall into presumed racial categories, such as such as North Africa, Polynesia or Tibet. DNA Tribes analysis does not make any assumptions based on non-scientific racial divisions. Instead of relying in presumed racial divisions, DNA Tribes defines world regions identified in a comprehensive database of world populations by objective mathematical criteria. Many of these world regions correspond to cultural or linguistic groups. For instance, Slavic-speaking peoples share a predominance of the Eastern European region. Other world regions cross national and cultural boundari
