By 21,000 years BP, and possibly thousands of years earlier, the Cordilleran and Laurentide ice sheets coalesced east of the Rocky Mountains, closing off a potential migration route into the center of North America.  Viability of the corridor as a human migration route has been estimated at 11.5k cal years BP, later than the ages of the Clovis and pre-Clovis sites.  Archaeological evidence of pre-Clovis people points to the South Carolina Topper Site being 16,000 years old, at a time when the glacial maximum would have theoretically allowed for lower coastlines. The land grant in the Treaty of Tordesillas (1494) opened up a whole range of possibilities for Spaniards, and in the following decades thousands of adventurers, petty nobles, and colonists set out for Cuba, Jamaica, and Hispaniola.They brought with them horses, cows, pigs, European crops and diseases, and appetites , The paleoclimates and vegetation of eastern Siberia and Alaska during the Wisconsin glaciation have been deduced from high resolution oxygen isotope data and pollen stratigraphy. The Ainu have developed antibodies to HTLV-1, indicating its endemicity to the Ainu and its antiquity in Japan. 2008) proposes that migration into Beringia occurred approximately 36k cal years BP, followed by 20k years of isolation in Beringia. (History documentary)  Among the 3764 samples, the Sakhalin – lower Amur region was represented by 61 Oroks. A 2016 DNA analysis of plants and animals suggest a coastal route was feasible. Pre-Last Glacial Maximum migration across Beringia into the Americas has been proposed to explain purported pre-LGM ages of archaeosites in the Americas such as Bluefish Caves and Old Crow Flats in the Yukon Territory, and Meadowcroft Rock Shelter in Pennsylvania. The study concludes that the ice-free corridor in what is now Alberta and British Columbia "was gradually taken over by a boreal forest dominated by spruce and pine trees" and that the "Clovis people likely came from the south, not the north, perhaps following wild animals such as bison".   Alpine glaciers in the coastal ranges and the Alaskan Peninsula isolated the interior of Beringia from the Pacific coast.  Subhaplogroup D4h3 from China does not have the same geographic implication as Subhaplotype D1a from Amur-Hokkaido, so its implications for source models are more speculative.  The HTLV virus genome has been mapped, allowing identification of four major strains and analysis of their antiquity through mutations. Settlement Of The Americas. The first human settlement of America could be located in southern Chile, and the place was occupied 1000 years sooner than you was previously thought. Arguably, talking to and reaching political settlements is difficult because religious claims are not easy to compromise; religion is a matter beyond a political bargain. February 14th 2001 By the late 1870s the thriving neighborhood had expanded to include 300 residents … Its parent lineage, Subhaplotype D4h, is believed to have emerged in east Asia, rather than Siberia, around 20k cal years BP.  It is possible that a small founder population had entered Beringia before that time.  Several models for the Paleo-Indian settlement of America have been proposed by various academic communities. The South American potato helped spark a population explosion in Europe. The visionary American film director has nine months to pay a settlement sum with the financiers of Voyage of Time, an epoch-straddling documentary that remains unfinished by Basic Books, The Settlement of the Americas: A New Prehistory. However, the exploration and settlement of America by Europeans did not begin for another 500 years. With further definition of subclades related to Native American populations, the requirements for sampling Asian populations to find the most closely related subclades grow more specific. , This model would help to explain the rapid spread to coastal sites extremely distant from the Bering Strait region, including sites such as Monte Verde in southern Chile and Taima-Taima in western Venezuela. , Stones described as probable tools, hammerstones and anvils, have been found in southern California, at the Cerutti Mastodon site, that are associated with a mastodon skeleton which appeared to have been processed by humans. The "marine migration hypothesis" is a variant of coastal migration which postulates the use of boats. They have a distribution ranging from coastal east Asia to the Pacific coast of South America. These populations expanded south of the Laurentide Ice Sheet and spread rapidly throughout both North and South America, by 14,000 years ago. , Subhaplogroup D4h3 has been identified among Han Chinese.
