You sound creationist to me.
If you paid attention at the 1st video some hornet was being attacked by more than one european bee simultaneously. There was even one dead hornet on
the floor. So the trait to gang up against the intruder is there.
Those colonies with a stronger ganging instict, especially against one scout, have better chances of survival. These stronger trait get preserved, the
others go extinct. With time the size of the ball can only increase in dimension until it involves the colony as a whole. That's how evolution by
natural selection works.
