A groundbreaking genetic study has revealed that Italians who reach 100 carry significantly more ancient Western hunter-gatherer DNA than their younger counterparts. The research, published in GeroScience, suggests that genetic echoes from our prehistoric past may hold secrets to exceptional longevity. Scientists found that every small increase in hunter-gatherer ancestry corresponded to a 38 percent higher chance of becoming a centenarian. Researchers from the University of Bologna analyzed genome-wide data from 333 Italian centenarians and 690 geographically matched controls. The findings demonstrate that ancient demographic processes continue to shape present-day patterns of human health and lifespan, challenging conventional understandings of longevity genetics.
