Researchers have discovered the bones of an ancient child that suggest modern humans and Neanderthals interbred around 100,000 years earlier than previously believed. Using CT scans and 3D mapping technology, scientists analyzed the child's remains, which appear to be the product of interbreeding between the two distinct human species. This finding challenges existing timelines of human evolution and interaction. Additionally, scientists have uncovered 13 ancient teeth that may further rewrite the understanding of human evolutionary history. Meanwhile, the extinct Denisovans, once widespread in Asia, remain without an official species name due to archaeological and legal complexities.
