Human beings do not have to live with a partner

Human nature is also weird. While loving one, there is no reluctance or paradox in giving heart to anyone else. The specialty is that it is not a special feature, but it is natural to be. Human nature is that he can not be loyal to anyone. Monogamy does not apply to any of men or women disciplined. In 2013, Cambridge University scientists team Clutan Brock and Dieter Lucas did a research. Here are some things about it
partners

A psychologist believes that there is no difference between man and woman when it comes to allegiance. It is often believed that men are more than willing to have more than one relationship as compared to women.
According to psychologists, men and women are naturally in a relationship with many partners. Compared to any other organism, humans are more likely to have genetically more chimpanzees and bonobos and because of this, our sexual nature also equates.
Among the mammals, primates ie monkeys, gorillas, chimpanzees and langur groups are such that 27 percent of the animals live with the same companion. The biggest reason for this is the fear of killing your children, for which primates decide to spend the entire life with one partner.
Behind the decision to spend life with a spouse in humans, this can be a big reason. Everyone is worried about their childhood, they worry about good upbringing. The situation is clear, not culturally, there is no trend of a single partner. But social concerns push us toward this tradition.

Again, scientists also say that there are three to five percent of mammalian organisms that are loyal to a partner.
