The new formula takes the dog to the age of the human
News / / December 19, 2019
The team of scientists from the University of California, asked the question that comes to mind each dog owners: how to find out how many years the animal in terms of human years? After a large-scale study they were able to derive the most accurate and scientifically based formula.
scientists compared the process of DNA methylation dogs and humans with age. To do this, we conducted a special blood tests of 320 people between the ages of 1 to 103 years and 104 labradors retviverov. Comparison of the data of the key points of physiological development revealed nonlinear age ratio. In mathematical notation, it looks like this:
human age = ln (age of the dog) * 16 + 31
The value ln - natural logarithm of the number - can be found using the scientific calculator (such a mode is, even in calculator iPhone). Or just drive to Google «natural logarithm (number)" - the answer will be the first same result.
According to this formula, 7-week puppy in human terms "corresponds" to a 9 month old baby. But puberty and sexual maturation in the dog runs much faster, and it also reflects the formula: one year old dog in '31 in human terms!
The formula is designed for dogs with an average life expectancy of 16 years, so the result will not be accurate for all breeds. Nevertheless, it is still more close to reality, rather than the traditional "multiply the age of 7."
