Why Ancient Humans Left Africa (And Almost Didn't Survive)

Did you know that every human alive outside Africa descends from a single, desperate group of a few hundred hunter-gatherers who nearly went extinct? For over 100,000 years, earlier human migrations failed, ending in total extinction. Discover the brutal history of climate collapse, ice ages, and sea crossings that forced our ancestors out of Africa to conquer Earth. A QUICK NOTE: To be honest, I’m not a fan of AI, but since English isn’t my native language and for a few other reasons, I figured it’s still the best tool for the job.
