Although a universal field of study, the archeological branch of the field of anthropology is still dominated by Eurocentrics who promote the theory that all of the world's continents as we know them today have always been inhabited by human beings except for Antarctica and the Americas. According to them, the Americas were originally uninhabited by humans, but later became inhabited by human migrations from Asia across the Bering Strait during an ice age, making Amerindians "First Americans" as opposed to "Indigenous Americans", which makes the European invasion and colonization of the Americas a little more excusable, being that Indians did not originate in America in the first place.
Most ancient Indigenous American oral traditions teach that yes, there were great migrations within the Americas on the part of Indigenous American peoples, including some contact with people of other eyes and colors, which is why there are genetic links among some Asian and Amerindian peoples. Nevertheless, Indigenous American oral traditions teach that the womb of Grandmother Earth from where all aboriginal American peoples sprang forth was Turtle Island, Anahuac, Amariku, etc. DNA evidence along with the Mexican footprints detailed on the following link are shrinking the Bering Strait myth and strengthening Indigenous American origin oral tradition more and more.
