14,000-year-old village unearthed in Canada

The oral history of the Heiltsuk Nation, an Aboriginal group based on the Central Coast of British Columbia, tells of a coastal strip of land that did not freeze during the ice age, making it a place of refuge for early inhabitants of the territory. As Roshini Nair reports for the CBC, a recent archaeological discovery attests to an ancient human presence in the area associated with the tradition. While digging on British Columbia’s Triquet Island, archaeologists unearthed a settlement that dates to the period of the last ice age. Continue reading “14,000-year-old village unearthed in Canada”

Two ancient populations that diverged later ‘reconverged’ in the Americas

A new genetic study of ancient individuals in the Americas and their contemporary descendants finds that two populations that diverged from one another 18,000 to 15,000 years ago remained apart for millennia before mixing again. This historic “reconvergence” occurred before or during their expansion to the southern continent. Continue reading “Two ancient populations that diverged later ‘reconverged’ in the Americas”

Ancient DNA analysis unlocks secrets of Ice Age tribes in the Americas Research

Scientists have sequenced 15 ancient genomes spanning from Alaska to Patagonia and were able to track the movements of the first humans as they spread across the Americas at “astonishing” speed during the last Ice Age, and also how they interacted with each other in the following millennia.

Ancient DNA evidence reveals two unknown migrations from North to South America

An international research team has used genome-wide ancient DNA data to revise Central and South American history. Their analysis of DNA from 49 individuals spanning about 10,000 years in Belize, Brazil, the Central Andes, and southern South America has concluded that the majority of Central and South American ancestry arrived from at least three different streams of people entering from North America, all arising from one ancestral lineage of migrants who crossed the Bering Strait some time before 15,000 years ago.
