@Aldo2 Let me guess, other human groups? Such as the native americans, the pre historical people's of Mesopotamia, modern day top secret black op proxy wars etc. the masses have been slacking from day one from day one we've been slacking. Monkeys just ooo and aaaa a lot unless it's 5 on 1 and people are the damn same no matter the race. "Rough and tumble" fighting style, Irish in origin, what we'd call today "dirty fighting", or "brutality", or "savagery", but no one race invented the dirty fight, the sneak attack, or the teamup.
