There was a segment about this on NPR a couple days ago, they suspect it is due to interpersonal relationships and Chimpanzee beef. They’re killing elders, killing babies, really brutal.

I don’t think people really understand how smart chimps are. They’re smart enough to be petty, this entire conflict could have stemmed from a single stolen mango.

The primary reason seems to be new alpha coming in and most of the older chimps that connected the two groups dying relatively close to each other.

They had a bunch of political marriages. Through coincidence the chimps involved in the marriages died and now they are at war.

Actually the war is just a distraction from the Epstein files. An orangutan started the war after his name appeared in the files 10k times.

A lot of animals are smart enough to be petty. Crows are really good about that. Humans are not as special as we think.

My brother once threw rocks at crows. They remembered him, and waited around for him to get home from summer school to caw at him. They brought friends. He never messed with crows again.

One of my neighbours shot a crow in his yard once and for the next few months, he would have an entire murder of crows perched close to his house and would caw at him whenever he went outside. He never shot another crow again lol.

'Man had always claimed he was more intelligent than dolphins, because he had accomplished so much - the wheel, wars, New York, and soforth - while all the dolphins had ever done was muck about in the water having a good time. Conversely, dolphins had always maintained that *they* were more intelligent than man.... for precisely the same reasons." -Douglas Adams

Superior enough that our interpersonal conflicts are now fought with drones. It's still petty. That or actual hate and want to inflict suffering like the recent bombings against Lebanon. Humans would rather kill others than be held accountable for their own actions.

Advances like your phone were only made possible because of contributions from the 0.1% most intelligent of our species. If all humans had the intelligence of the average human - we would still be in caves, if not extinct.

It was made possible through the ability to record knowledge and pass it down through multiple generations and across great distances. Einsteins have existed since hunter-gatherer times, but that doesnt mean said people could make an iron man suit in a cave out of scraps the way our ubermensch-inspired narratives portray the concept of intelligence. It wouldn't be possible even if there were 10000 stone age geniuses collaborating. Intelligence isn't a linear scale or a singular ability. Give most animals we consider "smart" the capacity to keep records and who knows where they'd be in a few thousand years. It's the ability to pass legacy through memetics (knowledge) instead of genetics (instinct) that makes us unique. We've effectively trivialized the biological game of information transfer using books and hard drives instead of genome sequences.

To put it simply, it’s Language. Oral and recorded. That’s one of the reasons we keep looking for it in other species. That and “tool user” have been pretty important things for researchers.

Yes, but the idea that animals are like animated plushies devoid of intelligence, which is widespread, is just absurd. Our intelligence isn't "special / different" - it's more that we've reached a threshold that allows us to build upon our own intelligence to achieve far more.

fallingdowndizzyvr 1 day ago +6
LOL. Someone small that needs to feel special by belittling other animals. Time and time again, we've had to redefine what separates humans from other animals. We use tools, other animals don't. But then we found they do. We make tools, other animals don't. Then we found they do. We have language, other animals don't. Then we found they do. We use medicine, other animals don't. Then we found they do. Stop being small. We aren't as special as you need to think to feel less small.

When Jane Goodall discovered the chimps were using tools that was actually the thing that we used to define mankind, we were man: the toolmaker. She wrote to Louis Leakey (the anthropologist who sent her to study the chimps, along with Dian Fossey to study gorillas and Biruté Galdikas to study orangutans) that “now we must redefine ‘man’, redefine ‘tool’, or accept chimpanzees as human.”

So its crazy that in a previous recorded conflict they could sort of pinpoint where it started which ape might have been attacked first and who in the tribe might have retaliated. Curious what exactly has to happen for things to deescalate among them?

You create a common enemy. Kidnap one alpha from each, send in robots to torture both apes, let the chimps work together to free themselves, "kidnap" them again from their prison and send them home to tell the tale 🧠👈

It's crazy how warlike chimps are. Gorillas put on a big show of displays, but at least they're mostly chill and just sit around munching leaves and playing with the baby gorillas and stuff. Chimps are so scary in comparison.

Chimps are absolutely brutal animals. Torture, infanticide and cannibalism of their victims is not uncommon. Their fiercely territorial attitudes are believed to be a mix of societal/interpersonal struggles + resource availability.

"humans are so awful, animals are better than us" people usually have no idea about how nature works. Ants literally fight proxy wars, a good chunk of mammals' mating would be r*** by our standards (which is also why humanising is dumb), f***, even plants kill nearby stuff to access more resources! Edit. Fixed "be" to "have" autocorrect typo

Going off on a phrase that the original commenter never said is slightly confusing. Have you been in that debate a few times? I think the argument mentioned against humans is also incomplete. Humans do savage things, as other animals do. But humans have a brain that allows them to act differently. A non-zero-sum society is possible.

Chimps are really smart, like pretty much as smart as we are in their own way. Obviously lack the language skills but they have their own strengths. It could be as simple as the other group not wearing the bits of grass in their ears and butts the right way, or they just don’t like the fuckers. Animals that smart can beef on levels we don’t really understand, just like humans. Like…does it make any f****** sense at all that the Hutu’s and Tutsis would hate each other? The Shias and the Shiites? Nah, not really, but people just be beefing.
40
Salt_Cardiologist122 1 day ago +15
Ok but we do know exactly why the Hutus and the Tutsis hated each other and honestly the reason is similar to the Shia/Sunni dynamic… differences in culture that got exploited by colonizers and then they gave the minority groups more power directly over the majority groups and eventually the majority groups didn’t want that anymore. We can talk about specific inciting incidents and all… but it’s really quite explainable. Also having read the article people quoted in the comments above… it does seem like there’s some clues about what happened with the chimps. It’s not some complete mystery that we have to dismiss as having “no sense.” The scientists are working to make sense of it and they know more every day.

Yes, f*** colonialism, but studies of ancient human groups suggest that up to fifty percent of males may have died from violence. It's not just an imperialism thing.

Not arguing your point btw. Just expanding.

_obseum 1 day ago +2
It’d be interesting to study the cause of the violence, because it’s the motivation that defines imperialism and its precursors. The root is the same though, a lack of respect for another human’s worth being used to justify violence.

The world's largest known group of wild chimpanzees has split and been locked in a vicious "civil war" for the last eight years, according to researchers. It is not clear exactly why the once close-knit community of Ngogo chimpanzees at Uganda's Kibale National Park are at loggerheads, but since 2018 the scientists have recorded 24 killings, including 17 infants. "These were chimps that would hold hands," lead author Aaron Sandel said. "Now they're trying to kill each other." The study, published in the journal Science, says the intensity and duration of the violence may inform how early human conflict developed. Wild chimpanzees filmed using forest 'first aid' Sandel, an anthropologist from the University of Texas in the US, and co-director of the Ngogo Chimpanzee Project, says chimpanzees are "very territorial", and have "hostile interactions with those from other groups". "[It's] like a fear of strangers," he told the Science podcast. But over several decades, Sandel said the nearly 200 Ngogo chimpanzees had lived in harmony. There were divided into two sets - known to researchers as Western and Central - but they had existed overall as a cohesive group. Sandel said he first noticed them polarising in June 2015, when the Western chimpanzees ran away and were chased by the Central group. "Chimpanzees are sort of melodramatic," he said, explaining that following arguments there would ordinarily be "screaming and chasing" and then later, they would grooming and co-operating. But following the 2015 dispute, the researchers saw that there was a six-week avoidance period between the two sets, with interactions becoming more infrequent. When they did occur, Sandel said they were "a little more intense, a little more aggressive". Following the emergence of the two distinct groups in 2018, members of the Western group started attacking the Central chimpanzees. In 24 targeted attacks since the split, at least seven adult males and 17 infants from the Central chimps have been killed, the study found, although the researchers believe the actual number of deaths are higher. The researchers believe many factors such as the group size and subsequent competition of resources, and "male-male competition" for reproducing may be to blame. But they say there were three likely catalysts: The first, were the deaths of five adult males and one adult female - for reasons unknown - in 2014, which could have disrupted social networks and weakened social ties across the subgroups The following year, there was a change in the alpha male, which the study says coincided with the first period of separation between the Western and Central groups. "Changes in the dominance hierarchy can increase aggression and avoidance in chimpanzees," it explained The third factor was the deaths of 25 chimpanzees, including four adult males and 10 adult females, as a result of a respiratory epidemic, in 2017, a year before the final separation. One of the adult males who died was "among the last individuals to connect the groups", the research paper said. Sandel and his colleagues said their findings encourage people to rethink what they know of human conflict and warfare. "In the case of the Ngogo fission, individuals who lived, fed, groomed and patrolled together for years became targets of lethal attacks on the basis of their new group membership," they wrote in the paper. If chimpanzees - one of the species closest to humans genetically - could do so without human constructs of religion, ethnicity and political beliefs, then "relational dynamics may play a larger causal role in human conflict than often assumed", they added. James Brooks, a researcher at the German Primate Center in Germany, said it was a "reminder of the danger that group divisions can present to human societies". Commenting on the study in Science, he wrote: "Humans must learn from studying the group-based behaviour of other species, both in war and at peace, while remembering that their evolutionary past does not determine their future."

Humans puzzled that our closest primate genetic relatives are having a seeming self-destructive dangerous conflict or war we can't make sense of.   Might even be a good idea to try to help stop it or resolve it.   *Really?!?!?!*   Oh, yeah, BBC article is paywalled.  Thanks, nope.   edit:  fix typos + As one researcher observed, "Compared to the chimps, who can seem like a ravenous murderous marauding horde perpetually at war - and if none exists, they'll get one started; the gorillas are more like a troupe of peaceful monks or an ascetic family who will defend their own if attacked or invaded or forced to compete, yet are relatively rarely violent or agitated and mainly calm and peaceful and even deliberate in action and interaction."
