The team of geneticists concluded that the attraction of opposites thesis is completely true. In any case, if we talk about our smaller brothers - chimpanzees.

Scientists have long been interested in the thesis that people try to choose partners for themselves that are extremely distant from them in genetic terms. Now geneticists from the United States decided to confirm (or disprove) this opinion by analyzing the behavior of several hundred chimpanzees. The site of the experiment was a national park in Tanzania.

Experts tracked the mating of animals and the birth of their offspring. DNA samples were collected periodically. As it turned out, the animals avoided mating not only with their immediate relatives, but also with unknown individuals that were genetically close to them. Even in those cases when females fell into a new tribe, they preferred males that were as “unlike” as possible to them.

This can be explained by the desire of evolution to maintain the greatest genetic diversity. However, scientists still cannot understand how monkeys conduct "genetic tests" when choosing a mate. Such markers can be, for example, smell, as well as the behavior of an individual.

The genus of chimpanzees includes two species: the common chimpanzee and the pygmy chimpanzee. Usually groups of these animals number ten to twelve individuals. Chimpanzees are the closest relatives of humans. The latest research shows that their genetic base matches that of humans by 98.7%.

Humans sometimes exhibit behaviors that are similar to those described in the chimpanzee experiment. So, tall ones can give preference to those who have a height below average. In addition, there are often cases when couples are formed by people with completely different psychological types. On the other hand, in the case of people, such a relationship is by no means proven and it is definitely early to draw 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.
