It has been made into a fascinating documentary:
Brothers in Blood: The Lions of Sabi Sand
(you can also find the video online for free if you search for it)
Lions are incredibly savage toward "the other"; no intra-species solidarity seems to exist, though there are incidents of strangers forming coalitions even though they didn't grow up together.
Chimps increasingly are being reported to be somewhat violent and are known to commit murder; cannibalism and rape also are not uncommon.
It's not clear, whether this behavior is continuous throughout their history as a species, or has come to be more common because of the pressure of human encroachment and the reduction in their population. At one time there were millions of chimpanzees in Africa, and today there are maybe 300,000 left in the wild.
All or most of the above would be classified as in-group violence by an objective observer, so it is difficult to agree with you that our ingroup violence as a species is much lower.
Do you think I am being downvoted for saying we have a lot of ingroup violence or for suggesting there is more ingroup violence in developing countries? These seem to be uncontroversial points.
I live in Nigeria. Children get beaten here. From their media, I know it's the same in other African countries, India, etc. Everyone accepts it and we are proud of it. But I know that in some developed countries you can be reported to child services for such. So I was careful not to imply that it's the same everywhere.
Still, according to page 172 of this report, it seems you're right, because UNICEF puts more effort at developing countries, although their scope covers much more than just domestic violence: https://www.unicef.org/publications/index_74865.html
You can walk into a village or bar full of strangers and you don't automatically get into a fights. You don't have to maintain your position with constant violence.
I doubt there is human culture where average adult gets into violent confrontation for status monthly.
One of my favorite (or, rather, terror-inducing) examples is the parasitic emerald wasp, which uses its paralyzing sting to turn a cockroach into a "zombie" so it can drag it by its antenna into a burrow, then lay eggs on the roach, and when the larvae hatch they proceed to eat the roach, but in a specific order so that the organs necessary for survival are eaten last. Queen Cersei from Game of Thrones couldn't come up with more nightmare-inducing torture.
The suffering in the natural world seems terrible to us, but it could be nothing in the face of larger, unknown forms of suffering. We are limited by our imaginations, having no reason to believe we have access to anything approaching deep universal truths of suffering or divinity.
I say this as an atheist. Your argument struck me as a poor one.
"we"? You don't speak for me.
You sound to me like you've had a decent life and it's you that can't imagine (consider yourself lucky). Not everyone has your fortune.
Your argument struck me as a poor one too.
In actuality, this and many other behaviors we share with chimps were most likely present in our last common ancestor. Tool use and complex social hierarchies are other shared behaviors. The split was some 7 million years ago, if memory serves.
When Goodall reported on the events of the Gombe War, her account of a naturally occurring war between chimpanzees was not universally believed. At the time, scientific models of human and animal behavior virtually never overlapped. Some scientists accused her of excessive anthropomorphism; others suggested that her presence, and her practice of feeding the chimpanzees, had created violent conflict in a naturally peaceful society. However, later research using less intrusive methods confirmed that chimpanzee societies, in their natural state, wage war. A 2018 study published in the American Journal of Physical Anthropology concluded that the Gombe War was most likely a consequence of a power struggle between three high-ranking males, which was exacerbated by an unusual scarcity of fertile females.
