Human migration theories

Human migration theories explore why and how people moved across the globe. They suggest that early humans dispersed from Africa due to factors like changing climate, searching for food, or overpopulation. Some theories highlight technological advances, such as tools and boats, helping migration. Others consider social reasons, like trade and conflict. Overall, these theories reveal that human movement was driven by a mix of environmental, economic, and social factors, shaping the diverse populations and cultures we see today.
