The possibility of voyaging contact between prehistoric Polynesian and Native American populations has long intrigued researchers. Proponents have pointed to the existence of New World crops, such as the sweet potato and bottle gourd, in the Polynesian archaeological record, but nowhere else outside the pre-Columbian Americas 1 – 6 , while critics have argued that these botanical dispersals need not have been human mediated 7 . The Norwegian explorer Thor Heyerdahl controversially suggested… 

Genomic insights into population history and biological adaptation in Oceania.

The authors' analyses reveal marked differences in the proportion and nature of Denisovan heritage among Pacific groups, suggesting that independent interbreeding with highly structured archaic populations occurred and that introgression of Neanderthal genetic information facilitated the adaptation of modern humans related to multiple phenotypes.

Ancient DNA Studies in Pre-Columbian Mesoamerica

How aDNA research has helped discern population dynamics patterns in the pre-Columbian Mesoamerican context is reviewed, how it supports archaeological, linguistic, and anthropological conclusions, and how it offers new working hypotheses are reviewed.

Peopling of the Americas as inferred from ancient genomics.

All ancient individuals in the Americas, save for later-arriving Arctic peoples, are more closely related to contemporary Indigenous American individuals than to any other population elsewhere, which challenges the claim-which is based on anatomical evidence-that there was an early, non-Native American population in the Americans.

Paths and timings of the peopling of Polynesia inferred from genomic networks.

This reconstruction of the branching Polynesian migration sequence reveals a serial founder expansion, characterized by directional loss of variants, that originated in Samoa and spread first through the Cook Islands (Rarotonga), then to the Society (Tōtaiete mā) Islands (11th century), and finally to the western Austral Islands (Tuha'a Pae) Islands and Tuāmotu Archipelago (12th century).

The genomic landscape of Mexican Indigenous populations brings insights into the peopling of the Americas

A genome-wide analysis of 716 newly genotyped individuals from 60 of the 68 recognized ethnic groups in Mexico shows that the genetic structure of these populations is strongly influenced by geography, and demographic reconstructions suggest a decline in the population size of all tested populations in the last 15–30 generations.

Admixture dynamics in colonial Mexico and the genetic legacy of the Manila Galleon

The specific origin of the heterogeneous Native American ancestry in Mexico is characterized: a widespread western-central Native Mesoamerican component in northern Aridoamerican states and a central-eastern Nahua contribution in Guerrero (southern Mexico) and Veracruz to its north.

Population interconnectivity over the past 120,000 years explains distribution and diversity of Central African hunter-gatherers

The results reveal that CAHG stem from a deep history of partially connected populations that allowed the coexistence of relatively large effective population sizes and local differentiation, with important implications for the evolution of genetic and cultural diversity in Homo sapiens.

The genetic legacy of the Manila galleon trade in Mexico

The population of Mexico has a considerable genetic substructure due to both its pre-Columbian diversity and due to genetic admixture from post-Columbian trans-oceanic migrations. The latter

Genomic insights into the recent population history of Mapuche Native Americans

It is shown that admixed Chileans underwent post-admixture adaptation in their Mapuche subancestry component in genes related with lipid metabolism, suggesting adaptation to scarce food availability.

The genetic scenario of Mercheros: an under-represented group within the Iberian Peninsula

This work analyzes for the first time the Merchero population, a Spanish minority ethnic group that has been scarcely studied and historically persecuted, and depicts their fine-scale ancestry components and genetic scenario within the Iberian Peninsula.

An early Amerindian contribution to the Polynesian gene pool on Easter Island is demonstrated, and the usefulness of typing for immunogenetic markers such as HLA to complement mtDNA and Y chromosome analyses in anthropological investigations is illustrated.

Molecular genetic studies of natives on Easter Island: evidence of an early European and Amerindian contribution to the Polynesian gene pool.

There may have been an early European and Amerindian contribution to the Polynesian gene pool of Easter Island through an introduction into Easter Island in the early 1800s, or earlier.

Native American Y chromosomes in Polynesia: the genetic impact of the Polynesian slave trade.

The finding that Native American Y chromosomes are detected on the Polynesian island of Rapa is best explained as the genetic impact of a 19th century Peruvian slave trade in Polynesia, and underscores the need to account for history before turning to prehistory.

Early human dispersals within the Americas

Analysis of the oldest genomes suggests that there was an early split within Beringian populations, giving rise to the Northern and Southern lineages, and that the early population spread widely and rapidly suggests that their access to large portions of the hemisphere was essentially unrestricted, yet there are genomic and archaeological hints of an earlier human presence.

Historical collections reveal patterns of diffusion of sweet potato in Oceania obscured by modern plant movements and recombination

The results provide strong support for prehistoric transfer(s) of sweet potato from South America (Peru-Ecuador region) into Polynesia and document a temporal shift in the pattern of distribution of genetic variation in sweet potato in Oceania.

Reconstructing the Population Genetic History of the Caribbean

It is demonstrated that the ancestral components in admixed genomes can be traced back to distinct sub-continental source populations with far greater resolution than previously thought, even when limited pre-Columbian Caribbean haplotypes have survived.

Ancient west Eurasian ancestry in southern and eastern Africa

Genome-wide genetic data is used to show that there are at least two admixture events in the history of Khoisan populations (southern African hunter–gatherers and pastoralists who speak non-Bantu languages with click consonants) and that west Eurasian ancestry entered southern Africa indirectly through eastern Africa.

A dual origin for the Polynesian bottle gourd is supported: the chloroplast markers are exclusively of Asian origin, but the nuclear markers show alleles originating in both the Americas and Asia.
