Paleo-Indian Period (15000 – 7000 B.C.)
The Paleo-Indian period traverses from circa 15,000 B.C. to the conclusion of the Pleistocene Ice Age about 7,000 B.C. The time period denotes the earliest colonization of the New World by Homo sapiens. It is commonly accepted that these ancient people came to the Americas from Asia, either by way of a landbridge that appeared across the Bering Strait or perhaps by use of simplistic water-craft which they could paddle from island to island. We are confident that these first inhabitants relocated to the New World because yet after a century of exhaustive research, no learning has ever been made of preceding human ancestors. Scientists consider that the Paleo-Indians may have accompanied herds of giant animals such as mastodons, mammoths, camels, and bison as they crossed the Bering land-bridge from Siberia to Alaska. The land-bridge was produced possibly by the formation of enormous glaciers and ice layers which led water levels to drop more than 150 feet. As water levels fell the Aleutian Islands, which spread across the Bering Strait, would have been joined together, connecting Asia to America.
