Nature’s Deadliest Mistake | The Archaeopteris Story | #Paleobotany

They ruled Earth for millions of years — then vanished almost overnight. 380 million years ago, the first forests covered the planet. Archaeopteris, Earth's first true tree, had built the world's first deep soils, reshaped rivers, and flooded the atmosphere with oxygen. Then something went catastrophically wrong. No asteroid. No volcano. The trees themselves triggered one of the largest mass extinctions in Earth's history — and nearly erased all complex life. This is the real reason the world's oldest forests vanished. ────────────────────────────── WHAT YOU'LL DISCOVER ────────────────────────────── → How Archaeopteris built — and then broke — an entire planet → Why the same roots that created soil also poisoned the oceans → The Kellwasser Event: the mass extinction nobody talks about → How an 80% drop in CO₂ froze the Earth and erased the forests → The chilling parallel between the Devonian extinction and today ────────────────────────────── CHAPTERS ────────────────────────────── 0:00 The First Forests 0:44 A Geological Mystery 1:04 No Asteroid.
