The expansion of people throughout North and South America began with the migration of early humans from Asia across the Bering Land Bridge, which connected Siberia to Alaska during the last Ice Age. As climate conditions improved, these groups spread southward and eastward over thousands of years, adapting to diverse environments. The development of agriculture around 10,000 years ago further facilitated population growth and settlement, leading to the establishment of complex societies and civilizations across the continents. Ultimately, trade, exploration, and cultural exchange among these groups contributed to the rich demographic tapestry we see today.
