Yeah.

I mean, listen, chimpanzees do the same thing.

Males will invade a rival territory and kill off individual males by ganging up on them.

This isn't a fair fight, right?

This is 10 to 1.

Beat the males, rival males to death from the rival troop.

Beat them to death.

And when they're shrieking in terror, their buddies in the rival troop don't rush to their aid like humans would.

They run away.

That's the difference between chimpanzees and humans.

is what's called the male coalition exists in chimpanzee society, but they don't run to the aid of their brothers when the chips are down.

They save themselves individually.

Humans don't do that.

We will rush to help a brother who's in danger, as it were.

Even at risk to our own lives, it's one of the few unique traits that humans have that other mammals don't.

Yeah, exactly.

No, because we're better off in a group, even a group in a desperate situation.

But chimpanzees, the rival troop that's getting beaten to death one by one, eventually they're wiped out because they don't form a coalition to defend, only to attack.

They'll form a coalition to attack, but not to defend, right?

So what happens is the more aggressive troop of chimpanzees...
