Climate Change and Human Migration

Migration has been a huge part of human history. Experts agree that early humans started out in Africa and began to migrate out of Africa to different parts of Europe and Asia around 100,000 years ago. This migration occurred in waves but we don’t know why early humans left Africa. Recent research supports the theory that climate change may have been the force that drove early humans out. Looking at things such as dust, buried pollen, and coral, scientists have been able to show a correlation between changes in these things and periods in early human history of migration. As early humans looked for new food sources, the research indicates, they began to relocate. Listen to hear more about what may have caused humans to migrate.
