Social status in baboons is dependent on the correct relatives

A female baboon may occupy a high position in the group if it will help mother and sisters.

Community, social animals are often organized hierarchically, that is, the group is sure to be the alpha species, then beta individuals subordinates and so on until the lowest level, which must obey all the others. It is clear that social status depends on the strength and size: the alpha male or alpha female will simply stronger than all. However, there are other factors affecting the rank of the individual. For example, female baboons "title" inherited, that is, the daughter high-ranking females occupy a high position within the group by right of birth. (Analogy with the human aristocratic birth is clear.)

However, this does not mean that social rank may not change. In an article published in Animal Behaviour, Zoology from Duke University describe how and why the female yellow baboons can be raised or lowered in rank. The researchers used data about the social structure of wild monkeys, collected over more than thirty years, from 1977 to 2010. To determine the social status of individuals by behavior: if a high ranking female is defiantly grins, sticks out his chest, slams his feet on the ground, then a low-ranking strongly evinces his fear, looks away and generally trying to move gently in close proximity to "superiors."

Analyzing changes in the behavior of AVIANA, zoologists have discovered that a quarter of females by the time of puberty changed her rank, rising or descending on the social ladder. The lower status happened when the mother and daughter were separated: for example, if the group was split into two parts, or the mother died before the daughter began an independent life. That is, in order to occupy a high position, the female baboon little born from the right mother – you need to mother patronized his daughter, as she grows up. Young monkeys builds social relations in games, and old females, interfering in the games of youngsters, help their children at this stage to occupy the appropriate social status.

Also mothers, female baboons help their sister. The more sisters, the more likely that the female grew up, will be in the same status as her mother. Senior help Junior to reach the top, but sisterly love has its limits: older sisters help to cope with aggression from other families, but when it comes to family status, then the younger members have to take action themselves.

It is curious, however, that the status of females does not depend on the status of the male half of the family, i.e., brothers and fathers. To explain this, it is obviously possible that the baboons-males mate with many females, and the male to protect any female, he would inevitably arise a difficult "conflict of interest" with yourself.
