So old your dog really is in human years

Who to compare a dog year seven human years, it is hard to say. Maybe this Person came up with the idea, because dogs are usually around ten years of age, while the global life expectancy for humans is around 70 years. Scientifically speaking, the comparison is nonsense.

But now, American geneticist from the University of California, San Diego have developed a formula with which the true Equivalent of dogs can be to people age calculate.

Therefore, a seven-week-old Labrador Retriever puppy is a nine-month-old human baby to be comparable; after about ten months, he comes into puberty, and celebrates the dog at some point his twelfth birthday, in people years, corresponds to a round 70.

The research team led by Tina Wang published his study on the Pre-Print Server bioRxiv. The geneticists draw on new findings in aging research: In the course of life the chemical structure of the DNA of some mammals, including humans and dogs, but also mice, chimpanzees, and wolves changed.

geneticists refer to this phenomenon as epigenetic clock. A long life with diseases and unhealthy habits over is, in fact, left its mark on the genome. Thus, methyl groups in time to specific DNA sequences, which allow to draw conclusions on the age of a human or dog.

reference points in the dogs-puberty

Specifically examined, Wang, and their colleagues, the DNA methylation of 104 Labrador retrievers, between four weeks and 16 years old. They noted that the methyl groups in the dogs sections, depending on the age of the characteristic Genome anlagerten as in humans. Particularly high is the correlation for both species was always then, when the body changes in just basic, such as during Teething or puberty.

also, remember that dogs grow up in a similar environment as the person, and in the case of diseases with the same methods could be lying. A formula that is a little more complex, as the dog multiply age of just seven to come eventually: in Addition, it requires a calculator with log key (ln). You take the age of the dog and press the ln. The result you multiply by 16 and add 31. This only works, however, when the animals are older than a year. An example: An eleven-year-old dog is in human years, now 69 and not 77 years old.
