Europe's Early Humans Extinct Due to Glacial Cooling

New research suggests that a previously unknown big freeze, characterized by a sudden drop in temperatures of more than 5 degrees Celsius, drove early humans out of Europe for 200,000 years. The freeze, which occurred around 1.1 million years ago, posed significant challenges to human survival as they lacked heating, warm clothing, and sufficient food. However, evidence shows that early humans eventually adapted and returned to Europe, possibly due to evolutionary changes such as increased body fat for insulation and improved hunting and survival skills. The findings shed light on the resilience and adaptability of early human species, including Homo erectus, in the face of extreme climate conditions.
