True Facts: The Mystery Of How Bees Build

We know honeybees build wax honeycombs where they can efficiently work together to produce honey. How did they ever learn to do that? Ze Frank takes us through the behavioral evolution of insect architects. Honeybees descended from wasps, who went through many phases on the way to building geometrically efficient nests. Ants and termites build elaborate nests, too, harnessing a new word I just learned: stigmergy. Honeybees are the best at making lovely hexagonal cells to build their combs, but it's not because they are all that smart. Hexagons are just what happens when you cram cylinders together in the most efficient way. In fact, their combs are not made of perfect hexagons all the way through. Still, those imperfections are a way of coping with uneven surfaces, so maybe they are pretty smart. Instead of an ad, there's a mere 30-second promotional message at 4:20.
