where did native americans originate from

Native Americans originated from peoples who migrated from Asia to the Americas via Beringia (a land bridge that connected Siberia and Alaska) during the last Ice Age, with the initial coastal and inland migrations likely occurring roughly 20,000 to 15,000 years ago. Over millennia, these founding populations diversified and spread throughout North and South America, giving rise to the diverse Indigenous peoples seen today. Modern genetic, archaeological, and linguistic evidence supports multiple waves of migration from eastern Asia into the Americas, with the majority ancestry tracing back to ancient East Asian populations that crossed into Beringia and then south and east into the continents.
