The genetics of several plant species has also been used to support pre-Columbian contact via the Pacific. For example, there is a genetically distinct sub-population of coconuts on the western coast of South America. This has been suggested to be evidence of introduction by Austronesian seafarers. [19]
Pre-Columbian contact between Alaska and Kamchatka via the subarctic Aleutian Islands would have been conceivable, but the two settlement waves on this archipelago started on the American side and its western continuation, the Commander Islands, remained uninhabited until after Russian explorers encountered the Aleut people in 1741.
1491: New Revelations of the Americas Before Columbus is a 2005 non-fiction book by American author and science writer Charles C. Mann about the pre-Columbian Americas. It was the 2006 winner of the National Academies Communication Award for best creative work that helps the public's understanding of topics in science, engineering or medicine.
This is one of many examples of Van Sertima's theories that Mesoamerican mythologies are based on Pre-Columbian African contact theories. Between narrative chapters, Van Sertima develops his main claims about African contact with the Americas in an essay style and includes images of artifacts, which primarily consist of photographs of ceramic ...
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 study does not address the question of separate migrations for these groups, and excludes other DNA data-sets. [ 8 ] The American Journal of Human Genetics released an article in 2007 stating, "Here we show, by using 86 complete mitochondrial genomes , that all Indigenous American haplogroups , including Haplogroup X (mtDNA) , were part of ...
Schematic illustration of maternal (mtDNA) gene-flow in and out of Beringia, from 25,000 years ago to present. The genetic history of the Indigenous peoples of the Americas is divided into two distinct periods: the initial peopling of the Americas from about 20,000 to 14,000 years ago (20–14 kya), [1] and European contact, after about 500 years ago.
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 ...
