Well that was disturbing.
you mean the part about how they patrol their territory and kill trespassers?
Direct link to the peer-reviewed study: [L. M. Southern, T. Deschner, and Simone Pika, Lethal coalitionary attacks of chimpanzees (Pan troglodytes troglodytes) on gorillas (Gorilla gorilla gorilla) in the wild, *Scientific Reports*, **11**, 14673 (2021)](https://doi.org/10.1038/s41598-021-93829-x)
Ah so the chimps only killed infant gorillas. That makes much more sense to me. I was wondering how they would kill an adult. I’m sure it’s possible with some eye gouging and neck biting eventually, but gorillas are massively strong, even in comparison to chimps.
From the article "Chimpanzees clearly revel in hunting and killing other primates, from monkeys to chimpanzees and even humans (mostly infants).
...Gorillas, by contrast, show very little interest in killing other species, whether in the wild or captivity."
Add to that 27 chimps attacked 4 adult gorillas - and you see the result...
In other words - if you spot chimpanzes in the wilderness, big chances you will be dead and eaten...
If you spot gorillas - stay calm to avoid offending them and all is fine. .
For clarity they only killed infants, and one chimp was severely hurt.
The title made me think they had killed an adult gorilla but that was not the case
Meanwhile ants of different species wage war against each other, use tactics and strategy and even negotiate truces, and have done so for millions of years...
One of my favorite things was learning that some ant colonies will invade an opposing colony, bite off the legs of the ants that produce nectar, then carry their defenseless nectar filled body back to their colony to use them as food storage. Ants are brutal.
Oh, and also Ant Slavery as well
Primates witness primates kill primates while other primates write articles about it and discuss it on primate maintained communications network.
Typical primate comment
Chimps truly are our closest relatives
Hot take: “harem” structures are hard countered by warlike trait. A community built to be protected by few elite behemoths might function on its own, but social species bypass the strength disadvantage.
I feel v uncomfortable drawing conclusions about evolution by the behavior of animals experiencing severe habitat loss
Does help potentially explain human evolution though. In the past we probably encountered exactly the same pressures and came through them in exactly the same way. Joined together to kill everything. A sobering thought.
how tf can a chimp kill a gorilla? are gorillas too peaceful?
p.s. i know chimps are strong, just didnt think a chimp could overpower a gorilla
From the article:
"In both cases, chimpanzees formed coalitions, attacked the gorillas, and used their greater numbers to their advantage".
"As the researchers note, chimpanzees had the advantages of a larger group, like hyenas when they occasionally kill lions."
“The chimpanzees then worked together to single out certain gorillas, and in both events they were able to separate the baby gorillas from their mother.”
1st attack: 27 chimps vs 5 gorillas. The slain gorilla was an infant.
2nd attack: 27 chimps vs 7 gorillas. Slain gorilla, also infant.
