Italian Scientists Link Super-Ager Longevity to Ice Age Hunter-Gatherer DNA
A team of Italian scientists has discovered a connection between the exceptional longevity of super-agers and inherited DNA from Ice Age hunter-gatherer populations in Europe. Led by Prof. Cristina Giuliani from the University of Bologna, the study compared DNA from hundreds of adults, focusing on how genetic ancestry affects aging. The research highlights that small differences in inherited DNA can influence how bodies manage stress and infection over a lifetime. The study utilized epigenetics to explore how chemical tags alter gene behavior across populations. Italy, with its diverse genetic history due to ancient migrations, provided a unique setting for this research. The study involved centenarians, individuals aged 100 or more, comparing their DNA with younger adults from similar regions. This approach aimed to reduce noise from normal aging factors, although it could not entirely account for differences in childhood conditions or environmental factors.
