Humans marry to avoid sexual disease

Humans marry to avoid sexual disease : Marriage is an evolutionary step of the human race from polygamy to protect reproductive health, ensuring good maintenance of the race.

Marriage is the evolution of humanity from polygamy to protect reproductive health, ensuring good maintenance of the race .

In 1995, Frank Sinatra hummed the lyrics "love and marriage parallel to horses and chariots" . It implies that love leads to marriage, which is inevitable. However, according to a new study the monogamous relationship developed in human history is not due to the romance of love.

The study, published in Nature Communications, says marriage comes from the need to control and avoid sexually transmitted diseases (STIs).

When sexually transmitted diseases quickly cause high infertility rates, marriage develops so that humans maintain monogamy to prevent sexually transmitted diseases - (Photo: Corbis).

Researchers use computer modeling with mathematical models to understand how different behavior in early human societies is different. They wonder monogamy - characteristics only in about 3% of mammals - why does it appear in humans?

Accordingly, scientists found that during hunting and gathering, some males were exclusively mated to a large number of female individuals. In these small groups, sexually transmitted diseases appear to be short-lived and have no significant effect.

But in the agricultural period, when people knew how to cultivate, the community opened more and more and more crowded, the rate of sexually transmitted diseases increased rapidly between polygamy society.

There are no modern drugs, the rate of infertility due to syphilis, gonorrhea, chlamydia (a sexually transmitted disease caused by chlamydia trachomatis bacteria, which can lead to infertility in both men and women. ) was very high. This leads to a change in mating behavior of people. From the old way to the monogamy.

In early societies, small people, small communities, polygamy maintained because of sexual diseases did not affect people much - (Photo: Reuters).

Chris Bauch, professor of applied mathematics at the University of Waterloo in Canada, and the author of the study, said: "This study shows that the spread of infectious diseases has strongly influenced the development. developing social norms ".

Professor explained: "Our social norms do not develop completely in isolation from what happens in the natural environment. On the contrary, we cannot understand social norms without understanding. their origin in that natural environment Our social norms have been shaped by the natural environment, in return, the environment is shaped by our social norms as we are realize more clearly ".

Thus, getting married is not just a romantic thing with spiritual meaning. Marriage is also the evolution of humanity from polygamy to protect reproductive health, ensuring good maintenance of the race.
