Chimps go to war with each other, humans have been doing so since before we were "human". There is literally no point in human history without documented violence.
I remember about a decade ago standing outside our house and watching an incredibly long trail of ants leading from an ant-hill in-between our patio bricks towards our driveway - I followed it figuring they were migrating to a different hill but it ended up leading to an absolutely massive swarm of I assume two different breeds/colonies of ants fighting - it was honestly very interesting to watch - like how you'd see medieval armies fighting in movies - the thin lines of combatants on either side walking to war ending up in a thick horizontal battlefront of ants and ant bodies.
Absolutely amazing stuff. Makes me wonder if humans are controlled by our pheromones/scents/secretions/etc more than we think we are.
I don’t know why but this comment triggered a memory of a toy I used to play with as a kid called Army Ants. I haven’t thought about this for 30 years.
They were small plastic to toy ants in military gear. Each ant had a squeezable butt, aka abdomen.
