<human>:  Who invented the honeycomb structure?
<bot>: Honeycombs are a natural phenomenon. They are formed by bees using their specialized glands. They are made of hexagonal cells, and each cell has a hexagonal shape. The cells are arranged in a hexagonal pattern, which is why they are called honeycombs. The hexagonal shape of the cells allows them to hold honey in the middle, while allowing the bees to move around and get to the honey without getting stuck.
