Termites have been building air-conditioned skyscrapers for 25 million years
Some trivia is so bizarre it forces you to rethink your entire understanding of the world. Check out the fact below, see how others reacted, and scroll down to dive into the verified science and history behind it.
African termite mounds — some up to 9 metres tall — maintain a remarkably stable internal temperature of about 31°C despite external temperatures swinging from 3°C at night to 42°C in the day. They achieve this through a sophisticated system of ventilation shafts: warm air rises through central channels, cools at the top, and recirculates through peripheral tunnels. The design has inspired architects studying passive building cooling. The mounds also cultivate fungus gardens, raise larvae, and protect a queen who lives 15–50 years. Termites began this civilisation 25 million years ago.
Architecture, air conditioning, and fungal agriculture feel like modern human achievements. Finding that an insect with a brain the size of a grain of sand has been running stable temperature-controlled cities with fungal food production systems for 25 million years suggests engineering intelligence is not exclusive to large brains.
