Detailed explanation-1: -Scientists one theorized that the ancestors of today’s Native Americans reached North America by walking across this land bridge and made their way southward by following passages in the ice as they searched for food. New evidence shows that some may have arrived by boat, following ancient coastlines.
Detailed explanation-2: -The traditional theory postulates human migration across the Bering Land Bridge and then southward through a deglaciation corridor in western Canada. However, current research supports a maritime route along the southern coast of the Bering Land Bridge and Gulf of Alaska, and then southward along the Northwest Coast.
Detailed explanation-3: -The settlement of the Americas began when Paleolithic hunter-gatherers entered North America from the North Asian Mammoth steppe via the Beringia land bridge, which had formed between northeastern Siberia and western Alaska due to the lowering of sea level during the Last Glacial Maximum (26, 000 to 19, 000 years ago).
Detailed explanation-4: -Whereas archaeologists once thought that the earliest arrivals wandered into the continent through a gap in the ice age glaciers covering Canada, most researchers today think the first inhabitants came by sea.
Detailed explanation-5: -Ice age. During the second half of the 20th Century, a consensus emerged among North American archaeologists that the Clovis people had been the first to reach the Americas, about 11, 500 years ago. The ancestors of the Clovis were thought to have crossed a land bridge linking Siberia to Alaska during the last ice age.
