Scientists have analysed the DNA of Jonathan, a 194-year-old giant tortoise, to understand the secrets of extreme longevity.

Scientists have analysed the DNA of Jonathan, a 194-year-old giant tortoise, in hopes of understanding how to extend human lifespan. The tortoise lives on the remote South Atlantic island of Saint Helena, in the grounds of Plantation House, the official residence of the governor. He is believed to be the world's oldest living land animal, a contemporary of Queen Victoria and Charles Darwin.

The genetic analysis has identified patterns in genes that appear to protect the functioning of mitochondria, the structures within cells that generate energy. These findings may offer clues about the biological mechanisms underlying extreme longevity and could inform efforts to help humans live longer.
