Being a leader still needs to be friendly

Like humans, baboons behave friendly often have good health, longevity and healthy babies.

In the herds of baboons, the monkey holds the leading role. Those "queens" have the right to mate with every male in the herd and enjoy the best food. Many people think that, with such favorable living conditions, the female monkeys will always have good health and give birth to perfect children, but the reality does not happen so, Livescience said.

'For baboons, the position in the herd is not an important factor for reproductive success , ' said Robert Seyfarth, a scientist at the University of Pennsylvania in the US.

Seyfarth and colleagues tracked 45 female baboons in the Moremi reserve in Botswana for 7 years. They pay attention to the behavior of each animal, and record the lifespan of the female monkey and their children. By measuring the levels of certain hormones in the monkey's faeces, they measured the stress level of each animal.

Based on the social relationship of female monkeys, the team divided them into three categories: friendly, alienated and lonely.

'Friendly' children behave well with all members of the herd, including those with lower rankings. They brush their fur, catch lice for others and maintain a close relationship with them.

Female monkeys in the 'alienated' group are also attached to many "grooming dogs " , but they appear aggressive to others. They are only friendly to higher-order female monkeys in the herd.

'Both friendly and alien monkeys enjoy health and reproductive benefits thanks to strong relationships with other members,' the team said.

Meanwhile, lonely female monkeys have the lowest level of friendliness. They change "you grooming" constantly and only try to win the higher-order female monkeys.

'The lonely monkey group's life style makes them constantly in a state of stress. Their lifespan is low and the risk of premature death of children born to them is also high , 'the research team asserted.

The research team said that in the world of primates, social personality and skills are related to the level of reproductive success.

"A beautiful beheaded baboon will have many sustainable relationships, an important factor to increase gene transfer opportunities for the next generation ," Seyfarth commented.
