Centuries of No Mixing in Papua New Guinea?!

Turns out, ancient Papua New Guinea was like a real-life 'no new friends' zone! Scientists just found DNA showing some groups lived side by side for centuries without intermarrying—even when they were just a few kilometers apart. The Lapita people and the locals didn’t mix for ages, and even nearby villages stayed genetically separate for six generations. Wild to think about how isolated these communities stayed, even as they launched epic seafaring journeys! #AncientDNA #PapuaNewGuinea #History #Science
