The leading theory about how early humans arrived on the American continents is that they walked from Asia to North America over a strip of land that has since been covered by the ocean. To get to this answer, you might start by researching the different theories about human migration to the Americas. One of the key pieces of evidence for the theory of humans walking from Asia to North America is the presence of Native American populations with genetic and cultural similarities to Asian populations. The most commonly discussed land bridge is called Beringia, which connected what is now Siberia and Alaska during periods of lower sea levels due to the last ice age. As the sea levels rose, this land bridge would have been submerged, preventing further human migration across it.
