Ancient Fossil Skulls in China Re-dated to 1.77 Million Years

In a groundbreaking study, two ancient skulls discovered in Yunxian, northern China, have been re-dated to approximately 1.77 million years ago. This makes these Homo erectus fossils the oldest hominin remains found in East Asia. Researchers used isotopic analysis of quartz from the sedimentary layers to determine the age, providing crucial insights into the speed and extent of early human migration out of Africa. Previously, it was believed that Homo erectus took over 140,000 years to migrate to East Asia, but this study suggests a much faster spread. The findings also prompt a reevaluation of who might have created the older stone tools found in the region, potentially indicating an even earlier wave of migration.
