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]
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 ] Upon the arrival of the Europeans in the " New World ", Native American population declined substantially, primarily due to the introduction of European diseases to which ...
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.
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 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.
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 ...
Map of Pre-Columbian states of Mexico just before the Spanish conquest. The pre-Columbian (or prehispanic) history of the territory now making up the country of Mexico is known through the work of archaeologists and epigraphers, and through the accounts of Spanish conquistadores, settlers and clergymen as well as the indigenous chroniclers of the immediate post-conquest period.
