Why do young men love?

Men who prefer women younger than themselves, and women choosing to older men, not only acting under the influence of cultural stereotypes. Those and other preferences in the age sex and marriage defined in the process of evolution. According to the scientists, both men and women of children is greater when the father for a few years older than the mother. They believe that in the course of natural selection worked out by representatives of both sexes compatible age preferences. As the study conducted in Austria, men are making the greatest strides in childbirth, when the partner of six years younger, female same children most of all, if the father is five years older.

One of the most famous fecundity of marriages in Britain confirms these figures are almost one hundred per cent. The Queen, which is now 81 years, for four years and ten months younger than the Duke of Edinburgh. They have four children - is more than twice the average for British families. However, in pairs, where a man much older, such benefits have been observed. Women whose partners are older than ten years, on average the same number of children, and how much those whose spouse under the age of five years. Results of the study are available from most convincing evidence that the Union, in which the older man and younger woman, became the norm for heterosexual couples in the course of evolution. So taken in most studied human societies, and this gives an advantage at birth progeny. In England and Wales in 26% of households husband younger wife, 48% - slightly over from one day to five years, and 26% of cases - for six years or more. In other countries, revealed similar patterns. And while the average difference in age may differ, the norm is always strong precedence half. On average in the world, men prefer women as partners to 2.66 years younger, and women - partners at 3.42 years older.

Similar trends are observed in the analysis of data on marriages around the world. This feature brings together different cultures and have long given rise to suspicion among scientists that it was formed in the course of evolution, since the difference in age in the historical perspective provided the birth and survival of more children. Usually such age preferences due to the fact that men are programmed to choose partners that are visible signs of the ability to bear children (and they are underlined at a young age). At the same time, women were believed to aspire to material wealth and status, which becomes more men with age. And although a new explanation in theory sounds logical, particularly researchers have been unable to prove that men are choosing younger wives and girlfriends, as well as women, go marry older people receive some benefit children at birth. A new study conducted by Martin Fiderom and Susan Huber of the University of Vienna, helped locate relevant evidence for the first time. The specialists examined a database of more than 10 thousand men and women from Sweden. All of the surveyed have children born to one partner. Details appear in the journal study Biology Letters.

Among men the average number of children increased, if the age is less than the partner. Pick this advantage reached with a difference of 5.92 years, and then again began to decline. A similar discovery was made by and for women: the average number of children increased if the partner was older, the figure reached a peak with a difference of 3.97 years, and then again began to fall. Perhaps the different figures for men and women due to the fact that in the sample was submitted only one marriage partner from each pair. In the case of a woman older than her partner, the figure is changing even more visible: the number of children declines sharply with each passing year difference. Perhaps this is largely due to the fact that women's ability to bear children decreases with age. Chances that a woman who partner over ten years, leads the family at a time when her fertility begins to decline. In the case of men older is not such an immutable fact.

The results show that from the perspective of evolution useful when men for a few years older than women, because the light appears more children. Scientists say: "The findings could explain why men usually prefer to take in his wife's women, who under the age, while women generally prefer men older than themselves. We concluded that age preferences for selecting partners benefit men and women in terms of biology, and this feature could formalize the process of evolution. " Scientists also found that when a person has children from first marriage, and then he comes into re-union, the new partner is generally younger than the first. This is true for both men and women. As the researchers believe, the choice of a younger partner is designed to compensate for the loss of the ability of reproductive rights. click here
