A new study showed that female bonobos often work together to stop aggressive males. This behavior was seen for 30 years in the Democratic Republic of Congo. This is the only place where wild bonobos live. Bonobos are relatives of humans and live in groups led by females. Even if males are bigger, female groups can chase them away. They often do this when food is close. The study was done by Harvard University and was published in Communications Biology. Experts say this teamwork helps make social rules in bonobo groups.

The study also found that female bonobos can help each other even if they are not family. This cooperation helps them stay safe and become leaders in the group. It is rare for female animals to have this power. The researchers believe this behavior may be close to early human life. Early people also used teamwork to become leaders. The study helps scientists learn how animals live together and why working as a group is important.
