The coastal migration hypothesis is one of two leading hypothesis about the settlement of the Americas at the time of the Last Glacial Maximum.It proposes one or more migration routes involving watercraft, via the Kurile island chain, along the coast of Beringia and the archipelagos off the Alaskan-British Columbian coast, continuing down the coast to Central and South America.
Examples of Clovis and other Paleoindian point forms, markers of archaeological cultures in North America. The Solutrean hypothesis on the peopling of the Americas is the claim that the earliest human migration to the Americas began from Europe during the Solutrean Period, with Europeans traveling along pack ice in the Atlantic Ocean.
Map of the Americas showing pre-Clovis settlements. Historically, researchers believed a single theory explained the peopling of the Americas, focusing on findings from Blackwater Draw New Mexico, where human artifacts dated from the last ice age were found alongside the remains of extinct animals in 1930s [31] This led to the widespread belief in the "Clovis-first model," proposing that the ...
According to the standard accepted theory, the Clovis people crossed the Beringia land bridge over the Bering Strait from Siberia to Alaska during the ice age when there was a period of lowered sea levels, then made their way southward through an ice-free corridor east of the Rocky Mountains, located in present-day Western Canada, as the ...
The most prevalent theory today is the coastal migration hypothesis, which argues that people migrated from Asia down along the western coasts of North and South America. [28] Monte Verde is located 8,000 miles south of the Bering Strait. Such a considerable distance was probably unreasonable to trek by foot, especially on ice. [29]
The Ice Free Corridor is a subject of debate among anthropologists in recent years. Recent studies have provoked skepticism, with areas of discussion including the lack of evidence of sufficient flora in the area to support megafaunal migration, [ 12 ] to radiometric dating placing the emergence of a corridor through the central Canadian Shield ...
Three major ice centers formed in North America: the Labrador, Keewatin, and Cordilleran. The Cordilleran covered the region from the Pacific Ocean to the eastern front of the Rocky Mountains and the Labrador and Keewatin fields are referred to as the Laurentide Ice Sheet. Central North America has evidence of the numerous lobes and sublobes.
The dark grey colour represents the ice-free areas, while green represents areas with sea ice. The Northwest Passage (NWP) is the sea lane between the Atlantic and Pacific oceans through the Arctic Ocean, near the northern coast of North America via waterways through the Arctic Archipelago of Canada.
