It’s Anthropology 101. At the end of the last ice age, around 13,000 years ago, retreating glaciers created an inland corridor connecting Siberia to the Americas. People from northeast Asia crossed the Bering Strait land bridge and entered a new world. From there, these people — often given the name Clovis, after a New Mexico site that was rich with the distinctive stone tools they made — rapidly spread and successfully adapted to the various ecologies they encountered. All Native Americans can trace their ancestry back to these First Peoples.
