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.
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.
The pre-contact dogs exhibit a unique genetic signature that is now gone, with DNA from the cell nucleus indicating that their nearest genetic relatives today are the Arctic breed dogs—Alaskan Malamutes, Greenland Dogs, Alaskan huskies, Carolina Dogs, and Siberian Huskies. [1]
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 ...
Major pre-Columbian earthworks have been discovered, including ceremonial sites, fortified settlements, mounded ring villages and agricultural and transport infrastructure. [12] Thanks to the development of remote sensing technology (and also due to deforestation ), it has been possible to document the pre-Columbian period's extensive ...
In 2007, evidence appeared to have been found that suggested pre-Columbian contact between Polynesians from the western Pacific and the Mapuche people. Chicken bones found at the El Arenal site in the Arauco Peninsula, an area inhabited by Mapuche, support a pre-Columbian introduction of chicken to South America. [15]
The researchers concluded that it was brought by early Austronesian sailors to the Americas from at least 2,250 BP, and may be proof of pre-Columbian contact between Austronesian cultures and South American cultures, albeit in the opposite direction than what early hypotheses like Heyerdahl's had proposed.
