Bonobos, who are chimps and a relative to humans, seem to be gentler and less violence than chimpanzees and humans. For example, female’s cooperation is a major part of bonobos daily lives. They use coalitions to achieve their goals. When female enter adolescence, they leave their family, migrate to a new community, and settle there. Bonobos bond from experience, not from kinship. In addition, in bonobos party stability produces female power. For instance, in order for females to develop supportive relationships, they need to spend time together bonding. In intercommunity aggression, large party size protects individuals from lethal raiding. When ecological pressures kept females from forming effective alliances, they became vulnerable to males interested in guarding them. Pairs of females may be jointly aggressive toward individuals. However, most females spend their time alone.
There is an increase in violence among females according to experts. Female involvement in violence tends to respond to and be associated with the same conditions and circumstances as males. However, different from males, females tend to join gangs to be with their boyfriends who are in gangs. Not only do females join gangs to be with their boyfriends, but they join female gangs as well. In any case, patterns of violence among girls are no different then they are for males. They fight in the streets and schools and commit burglaries and other crimes. Female attitudes about crime and violence tend to be just as casual and absent of remorse as violent male teens.
