Genetic studies of the peopling of the Americas: What insights do diachronic mitochondrial genome datasets provide?

Here we briefly review the evidence for current hypotheses on the peopling process of the Americas and discuss how ancient mitochondrial DNA can provide a unique temporal perspective.

Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity

We present genome-wide sequences of individuals from the northern Northwest Coast covering a timespan of ∼10,000 years and show that continental patterns of demography do not necessarily apply on the regional level.

Ancient individuals from the North American Northwest Coast reveal 10,000 years of regional genetic continuity

Here we report the genome-wide sequence of an ancient individual known as "Shuká Káa" ("Man Ahead of Us") recovered from the On Your Knees Cave (OYKC) in southeastern Alaska (archaeological site 49-PET-408).

A time transect of exomes from a Native American population before and after European contact

To investigate whether a pre-existing genetic component contributed to this phenomenon, here we analyse 50 exomes of a continuous population from the Northwest Coast of North America, dating from before and after European contact.

A continuum of admixture in the Western Hemisphere revealed by the African Diaspora genome

Here we present genetic variation from deeply sequenced genomes of 642 individuals from North and South American, Caribbean and West African populations, substantially increasing the lexicon of human genomic variation and suggesting much variation remains to be discovered in African-admixed populations in the Americas.

Postglacial viability and colonization in North America’s ice-free corridor

Our findings reveal that the first Americans, whether Clovis or earlier groups in unglaciated North America before 12.6 cal. kyr BP, are unlikely to have travelled by this route into the Americas. However, later groups may have used this north–south passageway.

Large scale mitochondrial sequencing in Mexican Americans suggests a reappraisal of Native American origins

The Asian origin of Native Americans is largely accepted. However uncertainties persist regarding the source population(s) within Asia, the divergence and arrival time(s) of the founder groups, the number of expansion events, and migration routes into the New World. mtDNA data, presented over the past two decades, have been used to suggest a single-migration model for which the Beringian land mass plays an important role.
