A few draw steady attention from many, becoming the center of repeated interactions<\/a>. Others remain on the edges, waiting for their turn to connect.<\/p>\n These moments may appear small at first glance, yet they carry real weight, shaping the structure and function of the entire society over time.<\/p>\n Grooming builds social bonds<\/p>\n Grooming is not just about cleaning. It helps animals relax, builds trust, and creates lasting connections. Each interaction adds to a web of relationships<\/a> that holds the group together.<\/p>\n Over time, these repeated actions form a social structure. No single moment stands out. But together, they define who belongs where.<\/p>\n For years, scientists grouped baboons and their relatives into two types of societies. One type had a single, tight group. The other had layers, with smaller groups inside a larger one.<\/p>\n This idea helped researchers compare species. But it also simplified a complex reality.<\/p>\n A new study shows that these categories do not capture the full picture.<\/p>\n A closer look at baboon societies<\/p>\n Researchers from Arizona State University<\/a> led a major project called the Comparative Analysis of Papionin Societies. <\/p>\n The team gathered data from 13 field sites across Africa. The dataset spans 135 years and includes 11 species.<\/p>\n Jacob Feder, who led the study, wanted to revisit a basic question. What do we really mean when we describe a society as single-level or multi-level?<\/p>\n Feder used familiar examples to explain the traditional view. \u201cSingle-level societies<\/a> are kind of like soccer leagues,\u201d Feder said. <\/p>\n \u201cEveryone is an exclusive member of their unambiguous team, competing against other teams to \u2018win\u2019 (access to good food, defend their territory).<\/p>\n \u201cIn general, people have positive feelings and relationships with those who are a part of their team, and are averse to those who aren\u2019t.\u201d<\/p>\n Multi-level social systems and networks<\/p>\n Feder compared multi-level systems to everyday school life.<\/p>\n \u201cEveryone\u2019s divided up into their respective classrooms, but they regularly pass by each other in the hallways, cross paths during lunch breaks and mingle during recess,\u201d Feder said.<\/p>\n \u201cWhile relationships within classes are generally stronger, there\u2019s no ill will (and sometimes even friendships) between classes and plenty of social glue keeping everyone together.\u201d<\/p>\n These examples help, but real data tells a more complex story.<\/p>\n A model for human evolution <\/p>\n It may seem natural to study chimpanzees to understand human evolution<\/a>. They are our closest relatives. <\/p>\n But baboons offer something different. They lived during the same period as early humans.<\/p>\n \u201cThis dataset focused on baboons and papionins because this group of primates has long been used as a sort of model for human evolution,\u201d Feder said.<\/p>\n \u201cBaboons, geladas and mangabeys were evolving around the same time as our early human ancestors during the Plio-Pleistocene (roughly 5.3 million to 11,700 years ago).\u201d<\/p>\n This shared timeline means they faced similar challenges. Studying them gives insight into how social systems may have formed under similar conditions.<\/p>\n Mapping entire social networks <\/p>\n To study relationships, researchers used social network analysis. Grooming made this possible.<\/p>\n Study co-author Joan Silk explained why grooming works so well. It is easy to observe and looks the same across locations. <\/p>\n Grooming also carries meaning beyond hygiene. It reduces stress and strengthens bonds.<\/p>\n Researchers tracked who groomed whom, how often, and for how long. These details helped map entire social networks.<\/p>\n Hidden variation appears<\/p>\n When scientists compared these networks, they found something surprising.<\/p>\n \u201cOne thing that we discovered in the data, which we had not previously suspected, it turns out that not all of these single-level societies are actually the same,\u201d Silk said. <\/p>\n \u201cIn some ways, they are very similar, strong kin biases, etc. However, some are more cliquish and some are more cohesive.\u201d<\/p>\n Two groups may share the same label but function very differently. Some spread social attention widely. Others form tight clusters with clear boundaries.<\/p>\n This shows that simple labels miss important differences.<\/p>\n Female baboons create social structures<\/p>\n The study also highlights who builds these networks.<\/p>\n Females play a central role in shaping the group, forming strong bonds with relatives while also building connections with high-ranking males.<\/p>\n Female baboons also show a clear preference for individuals who share a similar social status.<\/p>\n These choices may seem routine. But over time, they define the structure of the group.<\/p>\n \u201cFemales don\u2019t necessarily have more coercive power, but they are creating social structures,\u201d Silk said.<\/p>\n This view shifts how we think about influence. It is not only about dominance. It is also about relationships.<\/p>\n Questions still remain<\/p>\n Mapping social systems is only the first step. Scientists still want to know why these systems form.<\/p>\n \u201cThe ecological reasons of how and why you have these multi-level societies are still a big question,\u201d Silk said. \u201cAnd now that we\u2019ve done this work we can go after that.\u201d<\/p>\n Many factors may play a role. Food availability, predators, habitat, and group size all matter. Researchers can now test these ideas using richer data.<\/p>\n Social choices build human networks<\/p>\n This research offers a broader lesson. Social systems are not fixed categories. They are built through daily interactions.<\/p>\n Each small choice carries weight, from who sits together and who offers help to whom, to who builds connections that last over time.<\/p>\n Over time, these choices create complex societies. This is true for baboons and for humans.<\/p>\n If you look closely, the structure of any society begins with simple acts of connection.<\/p>\n The study is published in the journal Proceedings of the National Academy of Sciences<\/a>.<\/p>\n \u2014\u2013<\/p>\n Like what you read?
