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.
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 ...
Opening of an ice-free corridor did not occur until after 13,000 to 12,000 BP. [58] [59] [60] The early environment of the ice-free corridor was dominated by glacial outwash and meltwater, with ice-dammed lakes and periodic flooding from the release of ice-dammed meltwater. [58] Biological productivity of the deglaciated landscape increased ...
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 ...
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.
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]
A Texas substitute teacher is being investigated after allegedly urging ICE officers to come to his school. “I have many students who don’t even speak English and they are in 10th-11th grade.
Reenactment of a Viking landing in L'Anse aux Meadows. Pre-Columbian transoceanic contact theories are speculative theories which propose that visits to the Americas, interactions with the Indigenous peoples of the Americas, or both, were made by people from elsewhere prior to Christopher Columbus's first voyage to the Caribbean in 1492.
