The single primate married for fear of the child was

Research by British scientists suggests that the need to conserve children has spurred a tendency to live couples in primates. This trend is like advancing to human monogamy in evolution.

In the new study published in the American journal The Proceedings of Academy of Sciences , the team explained that young animals are difficult to survive and grow when only depending on their mother. Furthermore, when a mother animal joins a new male, her offspring are previously easily killed by males to create more reproductive opportunities.

The research team collected data of 230 primates, track genealogies and associations in these species. Bayse statistical reasoning method is applied to consider the behavior in the evolution process over time, including the elimination of young animals.

Scientists believe that due to the need to protect the fathers' animals, the habit of living in pairs is shaped and developed, becoming a mate-mate behavior in many primates and regimes. single marriage in humans during evolution.

The research team believes that the concern of being killed is the cause of the transition from mating to mate in primates. The need for help to protect the mother and child of the mother-in-law is also a contributing factor to this behavior and the single-marriage regime.

On the other hand, the cognitive requirement for living in a more complex community has made the brain grow in a longer life, so it requires long-term care and protection, requiring the stable role of the male to do it. dad.

Scientists also noted that the double-life survival rate in primates is 27%, while this ratio in other mammals ranges from 3% to 5%.
