Experts found that a particular role played fewer women in some animals, playing both genetic and polygamy. In particular, men who make up a couple with only one representative of their appearance live longer. As for women, they are prolonged with the expectation of education of children.
In humans, women live an average of 5.4 years longer than men. In 72% of mammals, the tendency is the same: women live an average of 12% longer than men. The situation with birds is already different: on average, men live 5% longer than women.
Researchers believe that the issue here is not only in genetics, but also in reproductive properties. In terms of mating of birds, as a rule, only a small percentage of animals between monogamous and mammals depends on it.
Another unexpected discovery was that individuals who cared about the offspring often live longer. This applies to primates, especially when the offspring remains for a long time.
Therefore, in terms of evolution, the man needs only two things to live longer: being a good parent and staying with the partner chosen throughout his life.
