<human>:  Who invented the honeycomb structure?
<bot>: Honeycombs are a natural phenomenon. They are formed by bees using their specialized glands. The bees build the cells by pulling together individual hexagonal wax plates and then filling them with honey. This process is called comb construction. The bees use their tongues to pull the wax plates together. The wax plates are made of a mixture of beeswax and honey.
