The study shows that dogs ‘DNA mutates five times faster than their owners’ genetic code.

According to a study, the useful life of animals is related to the rate of mutation in their genetic code.

Researchers have found that mammals, from tigers to humans, have about the same number of mutations when they die of old age.

But short-lived animals tend to deplete their allocation more quickly, according to the analysis of 16 species.

According to researchers, this discovery helps explain why we age and sheds light on one of the most complex mysteries of cancer.
