Scientists have figured out whether opposites really attract
The team of geneticists came to the conclusion that the thesis about the attracting opposites is completely truthful. In any case, if we talk about our smaller brothers - the chimpanzee.
Scientists have long been interested in the thesis that people are trying to choose their partners who are extremely far from them in genetic terms. Now, genetics from the United States decided to confirm (or refute) this opinion by analyzing the behavior of several hundred chimpanzees. The experiment has become a national park in Tanzania.
Experts followed the mating of animals and the birth of their offspring. DNA samples were collected periodically. As it turned out, animals avoided mating not only with their immediate relatives, but also with unknown individuals that were genetically close to them. Even in cases where females fell into a new tribe, they preferred males,as much as possible "unlike" them.
This can be explained by the pursuit of evolution to support the greatest genetic diversity. However, scientists can not yet understand how monkeys when choosing a partner, conduct "genetic tests". For example, the smell, as well as the behavior of a particular individual, can act as such markers.
The genus of chimpanzees includes two species: the common chimpanzee and the pygmy chimpanzee. Usually the groups of these animals number ten to twelve individuals. Chimpanzees are the closest relatives of a person. The latest research shows that their genetic base coincides with the human at 98.7%.
People sometimes exhibit behavior that is similar to the habits described in the experiment chimps. So, high can give preference to those who have growth below average. In addition, it is not uncommon for couples to form people with completely different psychological types. On the other hand, in the case of people, this relationship is by no means proven and it is definitely early to make far-reaching conclusions.
Earlier, we recall, a team of Japanese researchers found that falling in love is associated with a decrease in the volume of gray matter in the striatum of the brain.
