The most widely supported explanation for how humans populated the Earth is:
B) They migrated predominantly over land from Africa over the last 80,000 years.
This theory aligns with current scientific understanding, suggesting that anatomically modern humans originated in Africa and gradually migrated and dispersed across continents over tens of thousands of years, primarily through land routes. This migration led to the peopling of various regions across the globe.
