How strong was the bottleneck associated to the peopling of the Americas? New insights from multilocus sequence data

In spite of many genetic studies that contributed for a deep knowledge about the peopling of the Americas, no consensus has emerged about important parameters such as the effective size of the Native Americans founder population.

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.

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.

A2

Haplogroup A2 is an Native Americas branch on the maternal tree of human kind. The woman who founded this line lived between 13,900 and 17,400 years ago (Behar et al 2012b).
