From their announcement:
This technology fulfills a promise made by our CEO, Gilad Japhet, last year in RootsTech, and is the first of its kind. The Theory of Family Relativity™ traverses the worlds of family trees, historical records, and DNA testing by connecting billions of data points to craft a theory of how two DNA Matches on MyHeritage are related.
This theory is a game-changer in the world of genetic genealogy, and scans billions of family trees, historical records, and other databases to illuminate the relationships between DNA Matches. The Theory of Family Relativity™ is a prime example of MyHeritage’s passion for innovation, fusing the worlds of genealogy and DNA testing to help people break through genealogical brick walls.
Enjoy connecting in relative terms
