Humans have crossed the Bering Strait from Siberia at least about 14,000 years ago and began to live in present-day North America and Canada. There are Bluefish Caves and Old Crow Plains, where Paleo-Indians who settled in Canada at this time lived. Mean_, after the end of the Ice Age, when the land route connecting Afro-Eurasia and the Americas was submerged, human beings who migrated to the Americas began to develop their own culture. In some cases, they built permanent settlements, in others they farmed, and in others they continued their hunter-gatherer life in settlements. However, many of them were destroyed during the invasion of European colonists in the late 15th and early 16th centuries, and most of them can be found only through archaeological studies.
