Pre-Columbian population figures are difficult to estimate because of the fragmentary nature of the evidence. Estimates range from 8–112 million. [10] Scholars have varied widely on the estimated size of the Indigenous populations prior to colonization and on the effects of European contact. [11]
These pre-Columbian American culture areas may also roughly correspond to particular geographic and biological zones of the continent. During the thousands of years of native inhabitation on the continent, cultures changed and shifted. One of the oldest cultures yet found is that of the Clovis peoples. [1]
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 ...
Although the exact pre-colonization population count of the Americas is unknown, scholars estimate that Indigenous populations diminished by between 80% and 90% during the first centuries of European colonization. Most scholars estimate a pre-colonization population of around 50 million, with other scholars arguing for an estimate of 100 ...
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.
Map of Y-Chromosome Haplogroups - Dominant haplogroups in pre-colonial populations with proposed migration routes. A "Central Siberian" origin has been postulated for the paternal lineage of the source populations of the original migration into the Americas. [48] Membership in haplogroups Q and C3b implies Indigenous American patrilineal ...
Geneticists have variously estimated that peoples of Asia and the Americas were part of the same population from 42,000 to 21,000 years ago. [15] New studies shed light on the founding population of indigenous Americans, suggesting that their ancestry traced to both east Asian and western Eurasians who migrated to North America directly from ...
The Na-Dené, Inuit and Alaska Native populations exhibit haplogroup Q (Y-DNA) mutations, however are distinct from other Indigenous Americans with various mtDNA mutations. [ 82 ] [ 83 ] [ 84 ] This suggests that the earliest migrants into the northern extremes of North America and Greenland derived from later populations.
