Humans and monkeys share Machiavellian intelligence
Date:10/24/2007

When it comes to their social behavior, people sometimes act like monkeys, or more specifically, like rhesus macaques, a type of monkey that shares with humans strong tendencies for nepotism and political maneuvering, according to research by Dario Maestripieri, an expert on primate behavior and an Associate Professor in Comparative Human Development and Evolutionary Biology at the University of Chicago.

After humans, rhesus macaques are one of the most successful primate species on our planet; our Machiavellian intelligence may be one of the reasons for our success wrote Maestripieri in his new book Macachiavellian Intelligence: How Rhesus Macaques and Humans Have Conquered the World.

Maestripieri has been studying monkeys for more than 20 years and has written extensively on their behavior. He has studied them in Europe, at a research center in Atlanta, and on an island in Puerto Rico, where researchers established a rhesus macaque colony for scientific and breeding purposes.

Rhesus macaques live in complex societies with strong dominance hierarchies and long-lasting social bonds between female relatives. Individuals constantly compete for high social status and the power that comes with it using ruthless aggression, nepotism, and complex political alliances. Sex, too, can be used for political purposes. The tactics used by monkeys to increase or maintain their power are not much different from those Machiavelli suggested political leaders use during the Renaissance.

Alpha males, who rule the 50 or so macaques in the troop, use threats and violence to hold on to the safest sleeping places, the best food, and access to the females in the group with whom they want to have sex. Like human dictators intent on holding power, dominant monkeys use frequent and unpredictable aggression as an effective form of intimidation. Less powerful members of the rhesus macaque group are marginalized and forced to live on the edges of the groups
