Ancient DNA Reveals the Extinction Bottleneck

#ancientdna #humanorigins #africanbottleneck #prehistorichumans Between 900,000 and 800,000 years ago, something extraordinary happened — and nearly ended us. The global population of our ancestors plummeted to fewer than 1,300 breeding individuals. For decades, this mysterious gap in the human story puzzled scientists. Fossil records offered no clue. But by mapping ancient and modern genetic diversity, researchers uncovered a shocking truth: humanity once came perilously close to extinction. In this documentary-style deep dive, we explore how DNA from across Africa and Eurasia revealed the “bottleneck” that shaped all later human evolution. Learn how drastic climate change, long ice ages, and the collapse of ecosystems forced our ancestors to the edge — and how a tiny surviving population gave rise to every human alive today. Based on groundbreaking research published in Science (2023), this is the untold story of how the human species almost vanished — and the genes that still carry the memory of our near extinction.
