   Jonathan the 194-year-old Giant Tortoise's Genome Sequenced

   Jonathan, the world's oldest land animal, a 194-year-old Giant Tortoise, has had his genome sequenced. Scientists found gene variants and epigenetic changes that could contribute to his remarkable lifespan. The analysis reveals patterns on genes that appear to protect the functioning of mitochondria, which may help resist aging. This discovery may hold clues to human ageing and longer life.

   Why it matters

   Jonathan is an Aldabra tortoise and has been studied to understand the secrets of his longevity. His genome sequencing may provide insights into healthy aging and could potentially lead to new approaches for improving human lifespan. The study of Jonathan's genome is part of ongoing research into the biology of ageing.
