Recent genetic studies have also suggested that some eastern Polynesian populations have admixture from coastal western South American peoples, with an estimated date of contact around 1200 CE. [6] Scientific and scholarly responses to other claims of post-prehistory, pre-Columbian transoceanic contact have varied.
In February 2021, a controversial study claimed that Venetian glass trade beads had been found at three prehistoric Eskimo sites in Alaska. The authors believe the beads were transported from Venice, Italy, across Eurasia and over the Bering Strait, making this discovery "the first documented instance of the presence of indubitable European materials in prehistoric sites in the western ...
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.
Only one instance of pre-Columbian European contact – the Norse settlement at L'Anse aux Meadows in Newfoundland, Canada c. 1000 AD – is established beyond reasonable doubt.[2][3] is not technically correct, and can't be corrected just by adding "mainland" since Newfoundland is also an island.
The Institute for the Study of American Cultures (ISAC) was an organization devoted to the study of pre-Columbian contact between the Old and New Worlds. Although as an organization it did not espouse any particular theory, it was strongly oriented in a general way toward a hyperdiffusionist view that pre-Columbian contact had been extensive.
Ivan Gladstone Van Sertima (26 January 1935 – 25 May 2009) was a Guyanese-born British associate professor of Africana Studies at Rutgers University in the United States. [1]
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.
Two primary hypotheses emerged. One proposed that syphilis was carried to Europe from the Americas by the men who sailed with Christopher Columbus as a byproduct of the Columbian exchange. The other held that it previously existed in Europe but went unrecognized. These are referred to as the "Columbian" and "pre-Columbian" hypotheses. [6]
