Scientists found that chimpanzees and bonobos, our closest living relatives, form social networks similar to human friendship circles. They spend most time with a small group of close friends and family while maintaining weaker connections with others.

Chimpanzees and bonobos are our closest living relatives in the animal kingdom. A new study suggests that they organize their relationships just like humans do. Researchers from Utrecht University and Universidad Carlos III de Madrid found that these great apes form social networks that resemble human friendship circles.

The study looked at how chimpanzees and bonobos spend their time with each other. They found that most animals devote a large share of their time to a small number of preferred partners, while maintaining less intense relationships with many others. This is similar to how humans organize our social lives.

However, the two species don't manage their relationships in exactly the same way. Bonobos distribute their time more evenly among group members, creating a more equal social network. Chimpanzees, on the other hand, concentrate most of their effort on a smaller number of favorite companions.

As chimpanzees age, they tend to focus more attention on fewer social partners. This is similar to what happens in human relationships as we grow older. Bonobos, however, do not show this same narrowing of their social circles over time.

Why It Matters

Understanding how animals form social connections can help us learn more about cooperation, social learning, and emotional well-being in both humans and other animals. This knowledge could also improve our relationships with each other.
