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.
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.
Molecular genetics study suggests that surviving Amerindian populations derived from a theoretical single founding population, possibly from only 50 to 70 genetic contributors. [7] Preliminary research, restricted to only 9 genomic regions (or loci) have shown a genetic link between original Americas and Asia populations. The study does not ...
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.
The Cambeba were a populous, organized society in the late pre-Columbian era whose population suffered a steep decline in the early years of the Columbian Exchange. The Spanish explorer Francisco de Orellana traversed the Amazon River during the 16th century and reported densely populated regions running hundreds of kilometers along the river.
The technological and social development of pre-Columbian cultures are conventionally classified into five archaeological stages: Lithic stage or Paleo-Indian - hunter-gatherers using stone tools and weapons; Archaic stage - first settlements, first crops, subsistence; Formative stage - pottery, weaving, sedentary agriculture, ceremonial centers
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 ...
