The key to the dispersal history of modern humans—specifically the First Americans—is not the North American Native teeth, but the Australasian/Onge DNA of the South American “Population Y.”
➀The White Sands footprints (dated to 22 kya by three methods) support that the initial southward dispersal (Zero Wave/ZWSP) was composed of coastal maritime people.
➁The Jomon ancestor Sojin DNA related to the Onge and Maniq, represents an early migration wave preserved in insular refugia (“cage-like islands”). Therefore, this Sojin lineage is a candidate for the coastal route dispersal, supported by their maritime livelihood, such as the 38,000-year-old obsidian voyages off the coast of Izu.
