DNA from ancient hunters could hold the secret to living 100 years

Can you imagine the secret to living a century is hidden in prehistory? A fascinating study from Italy suggests extreme longevity has very deep roots, since scientists discovered a direct connection between centenarians and ancient hunter gatherers. Experts analyzed the genetic code of long lived people and found a surprising heritage, as these individuals carry variants from Ice Age populations. This genetic component, called the Villabruna lineage, acts as a protective shield against the passage of time.

The legacy of Ice Age survivors

Research in the journal GeroScience reveals data that looks like science fiction, because each increase in this ancestral DNA raises the odds of living longer. According to the data, these prehistoric genes boost the chance of being a centenarian by 38%, and this effect is even more powerful in women. Scientists believe that extreme climates and scarcity selected these variants, which is why they developed a metabolism more efficient than the modern one, in this way, what helped ancestors survive glacial winters now protects the body against aging.

A heritage that strengthens the modern immune system

This ancient DNA also strengthened the immune system of its carriers, granting them superior resistance against diseases of advanced age. Although longevity depends on good habits, this finding shows that our Paleolithic past continues to shape our current health. Italy served as the perfect laboratory to confirm that these remote genes still exist, and in conclusion, hunters from wild Europe defined the secrets to a long life thousands of years ago.
