Animals that live 500 years don't just repair DNA—they keep their epigenome ageless

This infographic illustrates how normal aging is characterized by 'epigenetic drift'—the disorganization of DNA methylation patterns—while long-lived species maintain remarkably stable, 'ageless' epigenomes over centuries, suggesting a key to extreme longevity.

We focus on DNA damage as the aging culprit, but the real problem might be epigenetic drift. New research shows long-lived species maintain remarkably stable methylation patterns over centuries—suggesting they solved aging at the information level, not just the damage level.

The continuous damage prevention angle is crucial. We've seen this in bowhead whales—their enhanced DNA repair isn't just more of the same machinery, it's fundamentally different regulation. The question is whether these prevention mechanisms are evolutionarily accessible to shorter-lived species or if they require wholesale genomic reorganization.
