Jonathan the giant tortoise is believed to be 194 year sprint old. Now, scientists are studying his DNA to understand how he has lived so long. Their findings point to genes that help repair cell damage and protect against cancer. They have also found patterns linked to the tiny structures inside cells that supply energy.

Could Jonathan hold a clue to why some living things age more slowly?

According to The Guardian and Reuters, researchers compared Jonathan’s DNA with that of other giant tortoises. They looked at chemical tags called methyl groups. These tags can switch genes on or off and change as an animal grows older.

One finding caught the team’s attention. Jonathan’s genes linked to mitochondrial function showed patterns more commonly found in younger tortoises. Mitochondria provide energy to cells, and problems with them have been linked to ageing and age-related illnesses.

Stephen Clark, a senior researcher on the project at the Kallel Foundation, said, “His mitochondria must be especially stable and that’s an insight into longevity in general.”

But does this mean scientists are closer to finding a way to slow human ageing?

Not yet. The study, points to a possible link between these DNA patterns and Jonathan’s long life. It does not prove that the patterns are the reason he has lived for nearly two centuries. Researchers say they need more work to confirm what they have found.

According to The Reuters, Jonathan’s life also shows that reaching an extraordinary age does not mean avoiding health problems. When former Saint Helena senior veterinary officer Joe Hollis took over his care in 2009, Jonathan had cataracts and could no longer smell. His beak was also in poor condition, making it difficult for him to find food. Hollis began hand-feeding him, and Jonathan later regained weight and recovered.

So, can Jonathan’s DNA help people live longer?

The findings offer scientists a new direction to explore, but there is still a long way to go. Tortoises and humans age differently, and what works in one species may not work in another.

Business Honor observes that Jonathan’s story raises an important question for longevity research. Scientists may learn how his cells stay healthy for so long, but understanding the process is only the first step. The real challenge is finding out whether those lessons can help people age more healthily.
