I find it fascinating and touching that the reindeer cyclon and the death spiral of ants look similar, yet has a very different meaning.

  • The reindeer cyclon is a genious tool of survival. - When frightened, reindeers form a cyclon. The young, old and sick can stay near the center and move very slowly. Strong members of the herd create a fast-moving band on the outer edge. The outer edge creates an illusion of a wall, from that predators can’t single out one animal to attack.
  • The death spiral is a deadly flaw in the system. - Ants move back and forth on a line of scent between the colony and their target (ie. a food source). But if they accidentally cross their old path and create a loop, they start walking round and round, until they die.
