#622 | A Short History of Fire

A million years ago, in a cave in South Africa, our ancestors did something no other animal has ever done: they controlled fire.

Fire cooked our food, shrank our guts, grew our brains, and gave us the deep sleep and fireside stories that made us human.

This is the story of our species' oldest technology, and how the same flames that built the modern world may now threaten it.

• Wonderwerk Cave evidence of controlled fire by Homo erectus
• Early humans managed fire for warmth, light and safety
