Often we equate breakthroughs with studying the new and unknown, but sometimes the answers to our questions are in our past. For example, in terms of individual health implications, genetic genealogy has led to some eye-opening findings. As Yaniv shares, he and his team “…found that genetic variations explain only 15% of the differences in lifespan between individuals…It means that our actions can matter more.” In relation to society at large, the study of genetic genealogy has been applied to cold cases and has aided law enforcement agencies to resolve previously unsolvable cases.

Watch Ehrlich’s TEDMED 2018 Talk to learn more about how genetic genealogy and large-scale DNA mapping is changing our perception of the role genetics plays in longevity and the way we fight crime.
