Researchers studying Jonathan, the worldâs oldest known terrestrial animal, have identified genetic variations and DNA methylation patterns that may help scientists investigate how some animals live exceptionally long lives.
The findings highlight potential roles for mitochondrial processes, DNA repair, and gene regulationâbut researchers caution that the study does not prove what caused Jonathanâs extraordinary age or offer a treatment for human aging.
