Preview: Season 32 Episode 18 | 48s
Check out swarm intelligence, essentially a living embodiment of social media in nature.
Get a look at some of the planet’s great gatherings, creatures that come together in inconceivable numbers — sometimes in millions, billions, even trillions. In the process, a kind of super-organism is created in which individual intelligence is superseded by a collective consciousness that shares information and moves with a single purpose for the benefit of all.
