- Jonathan's genome contains 287 unique gene variants
Researchers identified 287 unique gene variants that keep epigenetic switches regulating DNA repair and metabolism active. This prevents the accumulation of genetic wear and tear typically seen in aging Aldabrachelys gigantea.
- Field
- ageing and longevity
- What they did
- Researchers studied the genome of a 194-year-old giant tortoise named Jonathan and found that his DNA repair and metabolism genes function similarly to those in young tortoises, unlike the typical aging process.
- Why it matters
- This discovery helps explain how some animals achieve extreme longevity and could lead to new methods for slowing down aging in humans.
