From North Asia to South America: Tracing the longest human migration through genomic sequencing

Very genetics testing oriented. Several interesting
nuggets in there.

RATIONALE: The extent of basal divergences,
admixture, and degrees of isolation among
Indigenous North Eurasian and Native South
American populations remain debated, with most
insights derived from genome-wide genotyping
data. This study aims to deepen our
understanding of the ancient dynamics that
shaped contemporary populations in North
Eurasia and the Americas. By using large-scale
whole-genome sequencing of 1537 individuals
from 139 ethnic groups in these regions, we
examined population structures, elucidated
prehistoric migrations, and explored the
influence of past environmental factors on
the diversification of human populations.

"Our analysis of whole-genome datasets also
allowed us to infer thesplit time between
North Eurasians and Native Americans, which
occurred between 26,800 and 19,300 ya
(Fig. 2, D and E). This finding isconsistent
with estimates based on the recently
published paleonto-logical discovery of
human footprints in North America
(south-centralNew Mexico) dating back to
23,000 and 21,000 ya..."
