Do aggressive bonobo males have greater mating success?

Question

Accepted Answer

Aggressive Male Bonobos Exhibit Higher Mating Success

Aggressive male bonobos demonstrate greater mating success, securing more copulations with ovulating females. Contrary to the perception of bonobos as exclusively peace-loving, male bonobos engage in more frequent aggressive encounters than their chimpanzee counterparts. These disputes, however, are almost exclusively directed at other males and have not resulted in fatalities, distinguishing them from the more dangerous altercations seen in chimpanzees.
Increased Aggression Levels in Male Bonobos

Research indicates that male bonobos are more aggressive than male chimpanzees, engaging in significantly more aggressive encounters and physical altercations. Specifically, male bonobos were observed to have 2.8 times as many aggressive encounters and three times as many physical altercations compared to male chimpanzees. This finding challenges previous assumptions about bonobo social dynamics.
Correlation Between Aggression and Mating Success

A key observation from the study is the direct link between a male bonobo's level of aggression and its mating success. More aggressive male bonobos were found to win more copulations with ovulating females. This suggests that within bonobo communities, aggression among males is associated with reproductive advantages.
Nature of Male Bonobo Aggression

The aggression displayed by male bonobos is predominantly directed towards other males, a behaviour consistent with expectations given the social structure where females often hold higher social ranks. In contrast, male chimpanzees are more likely to direct aggression towards females. Bonobo male disputes are typically one-on-one, which may contribute to their frequency, and importantly, bonobos have never been documented to kill each other.
Comparison with Chimpanzee Aggression

Chimpanzee altercations, which can involve multiple males and lead to fatalities, carry higher costs, potentially limiting their occurrence. The comparatively lower stakes in one-on-one disputes among bonobos might explain why these interactions happen more frequently. The absence of lethal aggression in bonobos is a significant difference from chimpanzee interactions.
