According to conventional views, big-game hunters used a land bridge to traverse the Bering Strait from North Asia into the Americas (Beringia).This bridge was in use between 45,000 and 12,000 BCE (47,000–14,000 BP). Long into Alaska, isolated small bands of hunter-gatherers followed vast herds of huge mammals. Ice-free passages formed along the Pacific coast and North American valleys between approximately 16,500 and 13,500 BCE (or approximately 18,500 and 15,500 BP).
This made it possible for animals to travel southward into the continent's interior, which was followed by people. Along the coastline, people walked or utilized boats to travel. The exact times and paths by which the Americas were populated are still up for debate. At least two Paleo-Indian populations with distinct morphologies coexisted in various parts of Mexico 10,000 years ago.
