New research has found ways for many types of tortoises and tortoises to slow or stop the aging process altogether.
Experts suggest that all living things age and die, but not all living things weaken and deteriorate until they age and die.
Among other findings, the researchers noted for the first time that turtles, crocodiles and salamanders had a particularly slow rate of aging and long lifespans, based on their size.
The giant skull of Jonathan Seychelles, 190 years old, is considered the oldest land animal in the world.
They also found that protective properties, such as the solid shells of most turtle species, promote slow aging and, in some cases, even mild aging or even what is called biological failure to age.
Beth Reinke, the first author and assistant professor of biology at Northeastern Illinois University, said:
Therefore, they live a long time, which puts pressure on them to age slowly. We have found the strongest support for the tortoise protective phenotype hypothesis.
“Once again, it shows that the Turtles are unique as a group.”
Biologists Rita and Silva, who worked at the University of Southern Denmark, suggest that the findings suggest that aging (the process of deterioration) is not inevitable for all organisms.
Looking at tortoises and tortoises living in zoos and aquariums, we found that 75% of the 52 species show very slow aging and 80% show slower aging than modern humans.
David Miller, lead author on wildlife ecology and associate professor at Pennsylvania State University in the United States, said: Among many wild species.
“Understanding what delays animal aging gives us a better understanding of human aging, and we can also learn about conservation strategies for many endangered reptiles and amphibians.”
Studies show that some of these species can reduce the rate of aging in response to better living conditions in zoos and aquariums compared to wildlife.
Contrary to many theories, the research results suggest that the way animals regulate temperature (thermal blood and warm-blooded animals) does not necessarily indicate their rate of aging or life expectancy.
This group observed slight aging in at least one species in each fever group, including frogs and toads, crocodiles, and turtles.
“It sounds dramatic to say that they are not old at all, but because they have grown in the past, their probability of death does not change with age,” Professor Reinke said.
However, the researchers say that just because some animals are a bit older doesn’t mean they’re immortal.
That simply means your risk of death doesn’t increase with age, but it’s still above zero.
All of them die from unavoidable causes of death such as disease.
The findings are published in the journal Science.
