== North American migration == 

 The Beringian migration to North America doesn't belong in this article because it wasn't a coastal migration.  It was a gradual expansion of the range of hunters following following game animals that had nothing to do with the coast.  The ice-free corridor hypothesis is supported by no evidence and was proposed to explain evidence for rapid migration of humans into North America, presumed to be from out of Beringia.  In any event, the ice free corridor hypothesis isn't even remotely about coastal migration.   

 More recent work indicates that the initial spread of humans into North America was a waterborne migration along archipelagos from the Kuriles to the Aleutians to islands off the Alaskan coast.  The archipelagos were much denser than they are now because of the lower sea level and they were more habitable than the ice-bound coast.  The spread of humans south via the island hopping route was extremely rapid and occurred while the way out of the Beringian-western Alaskan plain was still blocked by ice.  Genetic evidence links the first migrants to the Americas with the aboriginal Japanese, who migrated from the Altai region via the Amur River corridor by 20,000 B.P.  Maritime skills had spread throughout coastal east Asia from Indonesia.   

 The section on the American migration needs to be rewritten for accuracy and thematic consistency with coastal migration.
