Population biologists have proven that the deceleration of aging is not anywhere16 октября, 2021
Scientists out of 42 scientific institutions 14 countries of the world compared the demographic data of 9 generations of people and 30 populations of different primates and found that an increase in life expectancy occurring in many countries is just a consequence of decline in death among children. Significant from the point of view of the population biology increase in life expectancy due to the slowdown of aging does not actually happen. In other words, deceive death until we do not work.
«The death of a person is inevitable. Regarding how many vitamins we will take how clean the environment will be or how often we carry out exercise — in the end we will also be designer, «the Fernando Savoro is convinced of the University of South Denmark, the head of the International Research Team. He is a specialist in applied statistics and mathematics in population biology.
He and his team were able to shed light on the hypothesis of an invariant pace of aging by comparing a large amount of data and patterns of birth and death of nine generations of people with information about 30 populations of primates, including gorillas, chimpanzees and baboons living in zoos and in the will.
Scientists analyzed the relationship between the expected lifespan, that is, the middle age of the death of the population representatives, and the equality of terms of life, measuring how much death depends on age,
The results showed that with an increase in the expected life expectancy, the indicator of equality of life time increases. For example, high equality of life time is observed in modern Japan or Sweden, where the majority in the population dies in 70-80 years. However, in the XIX century, in the same countries, the situation was different, and the mortality was high not only among old people. Then the life expectancy was also less.
In previous studies, the authors stumbled on the striking pattern between life expectancy and equality of life of people, from hunters and collectors to modern industrial countries. And contacting monkeys, scientists noticed that these patterns are in primates.
«We saw that not only people, but also other types of primates placed in other conditions, begin to live longer, because the mortality rate among the young and young people falls. However, this correlation is maintained only if early mortality decreases, and not due to the decline in aging, «said the researcher.
With the help of statistical and mathematical methods, scientists have shown that even small changes in the speed of aging bring together a population of baboons with a population of chimpanzees or even people.
However, the Sovchero does not exclude that medicine sooner or later will find a way to do something that the evolution could not: reduce the pace of aging.
