They've been watching us and what we do to each other.

We both do it because chimps and humans shared a common ancestor only 8 million years ago.

8 million years is a drop on the geological time scale, but on a species scale that’s an eternity. We went from Neanderthals and Denisovans to sapiens in a fraction of that time.

I am siding with the group that opens bananas from the bottom.

Which side is the bottom?

>Which side is the bottom?

i'll tell you this if it helps, for the cohort he wishes to join he meant to say top.

The primatologist Richard Wrangam once advanced the theory that tribe vs. tribe conspecific homicides - what he called coalitionary killing - are an evolved trait that was selected for in primates by some kind of pro-homicide selection pressures in the ancestral environment (where homicide reliably grants an advantage to the expected relative gene frequency of the perpetrator's genes). I haven't kept up with biology…

It seems obvious to me - it's the combination of two ideas: 1. When competing for resources, killing your neighbour frees up resources, which you can take. Most species of animal and even plants do this to some extent. 2. By collaborating in a group, you can achieve more than individuals acting alone. This is the idea behind teams, companies, countries, etc. Combine the two ideas, and you get war.

It's definitely not obvious, given that many, many gregarious species may certainly have inter-group clashes and skirmishes at territory boundaries but no full-scale war. Animals in general avoid violence between conspecifics, for the obvious reason that it's rarely worth the risk of being hurt unless you're very sure you're going to win. Dying for your group is something you almost never see outside eusocial species. Never mind dying in your prime reproductive age!

For those of us who are unlikely to make time to watch a 4-part documentary, are there any particular lessons about social/political dynamics that you learned that stuck out to you or felt particularly prescient?

I watched the entire 4-part documentary and loved it. In general the series gives you a raw look into the a-b-c's of primate politics. Chimps just like us and the rest of our ape cousins are preoccupied wi…

To be honest, we are fighting now over a 30kms wide strait ... also critical in a certain policitcal survival of sorts.

Here is the paper: https://www.science.org/doi/10.1126/science.adz4944 - it's interesting. I noticed there was a respiratory epidemic that killed 25 chimps naturally quickly, one would imagine that would have quite a societal destabilizing impact?

I wonder if chimps are sophisticated enough to believe in omens? Perhaps they saw the sudden deaths are some sort of sign that the established structure was weak or immoral.

> 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.

That's a weird thing to say. Studies of primitive tribes showed decades ago that they only seem to fight each other for a handful of reasons. Religion, ethnicity and political beliefs aren't among them. Fighting over resources, women and blood feuds are.

Supposedly academic anthropology had difficulties accepting these findings, especially the Yamomamö studies by Chagnon where he documented them going to war to steal each other's women, as it contradicted the popular idea of the noble savage.

If anyone is interested in going more in-depth on this, there's a four episode documentary series on Netflix called Chimp Empire [1]. I just saw it last week and it's fascinating stuff. You get to know the individual chimps in-depth (they all have names) and get to see conflicts in this "civil war" unfold. Plus I learned a lot about social and "political" dynamics among chimps.

This is reality TV with animals. Like any reality TV show, the events and reactions are manipulated. I wouldn't put any credibility on this.

I hope nobody decides to violate the prime directive and take sides in the chimp war. To the extent that they have good memory, they live in a world of finite resources, and their behavior was shaped by the forces of game theory as applied to tribes, this is more or less inevitable. You can read that as defeatism or just math. We can't overcome the force of game theory, but we can make it work for us by making our tr…

Prime directive doesn't apply because they are part of our home planet. Our actions or in-actions can improve or worsen their living conditions. Their natural world is gone anyway. We've changed it already.

There's also the 1,5h documentary Rise of the Warrior Apes which is sort of a "prequel" to Chimp Empire. It was filmed over a period of 20 years in the same location and documents how the researches originally came upon this unusual chimpanzee tribe. The production values are not nearly as polished as in Chimp Empire but in my opinion it was still an interesting watch if you find this kind of stuff fascinating. The researchers themselves talk a lot in this.
