Chimpanzees appear to have more hostile relationships between different groups. Even lethal aggression is not uncommon. This hostility has led researchers to assume that group conflict is an innate part of human nature.
Bonobos might be telling a different story about how social structures and communities have evolved over time.
“The ability to study how cooperation emerges in a species so closely related to humans challenges existing theory, or at least provides insights into the conditions that promote between-group cooperation over conflict,’ study co-author and German Primate Center evolutionary biologist Liran Samuni said in a statement.
The study looked at two groups of 31 wild adult bonobos in the Kokolopori Bonobo Reserve in the Democratic Republic of Congo over a period of two years. When the different groups of bonobos met up, they often fed, rested, and traveled together.
Indigenous groups have also been a major sign that cooperation and group solidarity is much closer to our human nature than the suvival of the fittest culture that capitalism nurtures.
Their critiques on European society created a huge wave of political discussion and ideas in Europe, even if they thought of the indigenous people as simple minded savages which they absolutely were not. On the contrary, they showed a much higher capability of quality discussion and reaching a consensus because it was a central part of the way they were organised. The chief didn't have power over them and couldn't command them, the group would have to agree with them in order to do something, so a chief should be very skilled in discussion and very knowledgeable so that they could succesfuly lead the others and gain their trust.
Their critiques were possibly what resulted in the formation of the idea of equality in Europe, a concept that wasn't at all relevant until then.
There's a reason why the "noble savages" trope became prevalent in western society as a way to intake these concepts while at the same time descredit them as concepts of a "more savage peoples" shit takes. Western society as a whole has been broken and subsumed under capital with most of it's cultural concepts of solidarity twisted, in a way most understand this in a subconscious concepts of "society is broken" but have no means to understand why it has been broken as saying capital is horrible/evil is tantamount to being the stereotyped "crazed doomsday preacher on the corner".
