Professionals said that in the first place breaks family relationships happen on the fourth and seventh years of marriage. Scientists argue that this phenomenon may be a vestige of the ancient era.

American biologists from the Institute of Rutgers learned that the most dangerous for couples is 4th and 7 years of life together. Specialists anthropologists have explained, what exactly at this time the representative of the stronger sex often leaves the family or begins to change spouses. A similar phenomenon experts called "seventh year itch".

Similar reasons and generality of this phenomenon anthropologist Helen Fisher has described in his own scientific books, which magnified "Anatomy of love: a natural history of monogamy, adultery and divorce". Fisher analyzed the statistical data collected in different countries over time and drew an analogy with the life of the primitive inhabitants of our planet. In consequence of this specialist learned that the basis of family breakdown is something else, as a legacy of a bygone era, tells the newspaper Red Orbit.

Anthropologist sent a note that, although the average length of marriage in the world is 7 years old, divorced often parted in the fourth year of a joint life. Also, Fischer reported that diverged first pair at the age of maximum willingness to bear and rear children: the representatives of the stronger sex in the 25-29 years old, and the young ladies in the 20-24 and 25-29 years. Citing similar statistics Fischer compares life on this planet and other living creatures.

She explains that among primates, only 25% are considered to be monogamous, and from among all mammals only 5% of the species are merged into the Union family for raising children. In birds, on the contrary, this feature is 90% and the birds stay together only as long as their Chicks will begin an independent life. "A bird hatching out of the eggs will die of hunger, if the male is not to feed her. Only a few mammals are in the same position. For example, foxes are extremely liquid milk, that's why they have almost continuously to feed the calves and wait until Fox will bring them food in the hole. When matured foxes away from their parents, they also leave", - interpreting the anthropologist.

Directly with this, the scientist, partially binds and separation of the inhabitants of our planet. According to materials contained in the book, the inhabitants of our planet have been preserved remnants of this behaviour in hunter-gatherer societies women give birth to about 1 time in 4 years. In the same period, the children move on to education to the tribe as a whole, and ancestors have the opportunity to choose a new partner.

In the opinion of the evolution of this strategy allows you to leave more genetically diverse offspring. Therefore, divorce is in the four-year anniversary of marriage may be a vestige of the ancient era in the history of the earth's population, says Fischer. And yet, the expert believes that it is not necessary to justify their own decisions biological past. She expresses the opinion that the reference to the behavior of foxes is unlikely to be a significant argument for the court in divorce cases.
