This is pretty fascinating. It's always interesting how easily we can connect the oucomes of these experiments with us humans and society. It seems like some fundamental features of societal behaviour go right down the evolutionary chain. We see such things as torture, slavery, capitalism, war, farming, sacrifice, and more in societies of other apes, even ants.
But tbh, I don't need a research paper to tell me overcrowding is a bad idea! Give me space or give me death heh.
Yeah, there a lot of relatable behaviour that can be seen among animals and humans...some go down to our genetics.
This is why in the bible, some animals were sacred and not to be killed for food...The religious leaders wanted people to learn from them...like snakes, animals with paws and the like.
Lol, your view of having space is probably the more popular one...
