Politics is a dangerous game, even for primates.

It’s a plot line that wouldn’t seem out of place in an episode of “Game of Thrones.” A tribe of chimpanzees in West Africa beat up, murdered — and then ate — a member of their own tribe.

The victim was a 17-year-old chimp named Foudouko. His alleged crime? Piss-poor leadership.

The rise and fall of Foudouko

In 2005, in a 10-square-mile stretch of savanna in southeastern Senegal, an ape named Foudouko ascended to power and ruled over more than 30 western chimpanzees.

But Foudouko’s aggressive leadership style rubbed some of the younger, potential alphas the wrong way, and when his deputy and closest ally, Mamadou, suffered a leg injury in 2007, the tribe seized the opportunity to stand up to Foudouko.

Mamadou eventually returned to the group, but his gaunt physique caused his social standing to suffer; he was no longer the tribe’s beta.

Jill Pruetz of Iowa State University has been studying this tribe of chimps since 2005 and is the co-author of a three-year study published in January that focuses on intragroup lethal aggression in West African chimpanzees. She describes Foudouko as “somewhat of a tyrant.”

And it appears Foudouko’s tribe agrees with her assessment because in 2008, two years after the chimp became the group’s alpha male, he was overthrown. Exiled from his tribe, Foudouko was forced to live on the fringes of chimp society for five years.

The gender politics of chimpanzees

When female chimpanzees reach sexual maturity, they leave their birth communities in search of a new tribe — this is an evolutionary adaptation designed to help chimps avoid inbreeding. The smaller and more isolated the tribe, the more likely a female is to leave.

Male chimps remain in their natal communities, where they attempt to climb the social ladder by asserting their alpha status and building coalitions of likeminded allies.

When Foudouko was exiled from his tribe in 2008, he realized that his only chance at finding a mate was to rejoin his group. In 2013, he got an opportunity: Mamadou’s brother, David, had become the tribe’s alpha and Mamadou was back in the beta slot.

The brothers welcomed Foudouko back into the fold, but memories of his despotic behavior still grated on younger chimps who were coming up in the tribe’s hierarchy.

Foudouko’s tribe is unusual in that it has more males than females. (Jill Pruetz believes that humans caused this gender imbalance: female chimps are often poached from their tribes and forced to give birth to infants who will later be sold in the pet trade.) An uneven distribution of males and females ratchets up the competition for reproduction, leading researchers to speculate that Foudouko might have been attacked by other male chimps after approaching a female chimp who was in heat.

Coup d’état

In the early dawn of June 14th, 2013, Jill Pruetz and her assistant awoke to the sounds of chimps in an uproar. Upon investigation, they discovered Foudouko’s body spread-eagled on the ground; he was dead.

The wounds on his body gave the scientists some insight into what might have happened: injuries on Foudouko’s fingers imply that at least two chimps held him down while others beat him. His body was covered in blood leaking from a bite wound on his right foot and a gash on his back. It appears other chimps from the tribe cracked his ribs and ripped his anus open.

It is not unusual for chimps to battle with neighboring tribes, but it is uncommon for them to murder within their own ranks. Foudouko’s killing is one of only nine examples where a group of chimps has killed one of their own adult males.

Cannibalism among apes is even less likely. But that’s exactly what happened next: Researchers say that even after Foudouko’s death, members of his tribe continued to throw rocks, prod the body and rip off pieces of flesh with their teeth.

Surprisingly, most of the aggression stemmed from Farafa, the mother of Foudouko’s two closest allies, Mamadou and David. In an interview with New Scientist, Pruetz says:

“It was striking. The female that cannibalized the body the most, she’s the mother of the top two high-ranking males. Her sons were the only ones that really didn’t attack the body aggressively.”

This is pure speculation, but it seems that Farafa felt Foudouko was a bad influence on her sons and was taking out her anger on her sons’ friend’s body.

Politics is a dangerous game

Chimps, like humans, kill for many reasons: to expand or defend territory, to ensure their genes will be passed on, to impress mates or protect their food sources. But if Foudouko’s story is any indication, chimps also kill to send a political message.

Politicians everywhere would be wise to take note: Piss off your constituents and you might get your anus ripped out.
