New DNA Evidence Finally Settles How Humans First Reached Australia (50,000 Years Ago)

Video Description

Scientists Finally Prove How Ancient Humans Crossed 100km of Ocean to Reach Australia For generations, we've been told that early humans walked to Australia across land bridges during the Ice Age. But there's one massive problem with this story: there was never a land bridge to Australia. Even at the peak of the last Ice Age, when sea levels dropped over 120 meters, a minimum of 90-100 kilometers of treacherous open ocean always separated the continent from mainland Asia. This means that over 50,000 years ago, Ice Age humans didn't just stumble into Australia—they deliberately sailed there. And new DNA evidence has finally revealed exactly how they did it, who they were, and why this changes everything we thought we knew about ancient human capabilities. In this video, we explore the groundbreaking genetic research that has settled one of archaeology's greatest debates. We examine the ancient super-continents of Sunda and Sahul, the mysterious barrier region of Wallacea, and the extraordinary maritime journey that required sophisticated watercraft, navigation skills, and careful planning—all achieved by people we once thought were primitive hunter-gatherers. The DNA evidence reveals not only when these ancient mariners arrived, but also their encounters with Denisovans—an enigmatic archaic human species whose genetic legacy still exists in Aboriginal Australians today. We'll explore what it took to cross the open ocean without maps, compasses, or metal tools, and why this journey represents one of humanity's most daring achievements.
