But sometimes this chemical process also produces other products that end up damaging our tissues and cells over long periods of time. When this happens, we see signs of aging, such as wrinkles.
A second idea about why turtles live so long is also related to that low metabolism. Turtles often hibernate.
They sink down into the mud at the bottom of a lake or pond, going dormant for the season kind of like hibernation , and use even less energy.
A third idea about why turtles seem to outlive so many other animals is one that Holmes likes best. She said it holds true for animals that have evolved special defenses against predators. This is a benefit for each individual turtle. Lots of years to live also means that there is more time to breed and produce baby turtles who also have hard shells for defense.

Garrick, Michael A. Russello, Nikos Poulakakis, Stephen J. Gaughran, Danny O. George lived on the Galapagos islands, which inspired Charles Darwin's theory of natural selection.
He died in , at the age of around years old, according to scientists' estimates, the BBC reported. He was the last of the Chelonoidis abingdonii, or Pinta, tortoises who are said to live up to Read more: Bee death: scientists warn common weed killer glyphosate is killing honeybees. Scientists believe the lifespans of giant tortoises like George are so long because they have gene variants that tweak how their DNA is repaired and their bodies respond to inflammation and the development of cancer.
Prior to the study, little was known about the genes of these invertebrates.
