## Genetic Longevity Traits
Scientists found links to dna repair, mitochondria, insulin control and telomere function in Jonathan's genome and epigenome.
## Unique Genetic Markers
Jonathan has 287 unique genes and extra copies of a cancer-fighting gene that hunts down aging and cancerous cells.
## Longevity Research
Researchers compared Jonathan's epigenome with four other Aldabra tortoises to study aging mechanisms.
## Age and Resilience
Jonathan, mostly blind but still hungry, has lived through world wars and the rise and fall of empires.
## Symbol of Resilience
Jonathan is a beloved island symbol of resilience, longevity, and endurance through historic events.
## What Happens Next
Scientists may use Jonathan's traits to understand human aging and longevity mechanisms.
## Key takeaway

Jonathan, a 194-year-old Aldabra giant tortoise on St Helena, may live long due to genetic traits and youthful cell systems.
