Long-lived bats survive 40+ years through unique DNA repair adaptations

This infographic compares the cellular mechanisms contributing to lifespan differences between typical mammals (mouse) and long-lived bats. It highlights how bats achieve exceptional longevity and cancer resistance through enhanced DNA repair capabilities and altered cell cycle checkpoints.

Bats are the longest-lived mammals relative to body size. A 20-gram Myotis bat can live 40 years—a mouse of the same size lives 3. This 10x lifespan difference demands explanation.

New genomic evidence suggests bats evolved enhanced DNA repair through duplicated repair genes and altered cell cycle checkpoints. This may explain their cancer resistance and exceptional longevity.
