On his voyages across the Pacific, Captain James Cook encountered geographically disparate Polynesian societies, including those living on Easter Island, Hawai’i, and the north island of New Zealand. These far-flung communities cultivated a South American domesticate, the sweet potato (Ipomoea batatas). Subsequent debates concerning the timing and nature of the dispersals of sweet potato into and across the Pacific have proven contentious, including Thor Heyerdahl’s famous Kon Tiki voyage from… 

Origins, Divergence, and Contrasting Invasion History of the Sweet Potato Weevil Pests Cylas formicarius (Coleoptera: Brentidae) and Euscepes batatae (Coleoptera: Curculionidae) in the Asia-Pacific

Cylas formicarius has divergent mitochondrial lineages that indicate a more complex biogeographic and invasive history than is presently assumed for this insect, suggesting it was widespread across the Asia-Pacific before the arrival of sweet potato.

European and Asian contribution to the genetic diversity of mainland South American chickens

It is demonstrated that modern-day genetic diversity of mainland South American chickens appear to have clear European and Asian contributions, and less so from Island Southeast Asia and the Pacific Islands, and there is also some indication that South Asia has more genetic contribution to European chickens than any other Asian chicken populations.

Human translocation as an alternative hypothesis to explain the presence of giant tortoises on remote islands in the south‐western Indian Ocean

It is proposed that giant tortoises were introduced to the IO islands by early Austronesian sailors, possibly to establish provisioning stations for their journeys, just as European sailors did in more recent historical times.

The Human Landscape: Population Origins, Settlement and Impact of Human Arrival in Aotearoa/New Zealand

The settlement of the Polynesian Triangle, culminating with the settlement of Aotearoa/New Zealand within the last 750 years, represents the last major migration event of humans as they dispersed

Indigenous Polynesian Agriculture in Hawaiʻi

Agriculture in Hawaiʻi was developed in response to the high spatial heterogeneity of climate and landscape of the archipelago, resulting in a broad range of agricultural strategies. Over time,

‘Polynesians’ in the Brazilian hinterland? Sociohistorical perspectives on skulls, genomics, identity, and nationhood

In 1876, Brazilian physical anthropologists De Lacerda and Peixoto published findings of detailed anatomical and osteometric investigation of the new human skull collection of Rio de Janeiro’s Museu

Breeding Sweet potato [Ipomoeaebatatas (L.) Lam] For Low Moisture Stress Tolerance

Sweet potato is important sources of carbohydrates, vitamins A and C, fiber, iron, potassium, and protein, potato is also used as animal feed. Increasing recognition of the great potential of the

A Vavilovian approach to discovering crop-associated microbes with potential to enhance plant immunity

Considering the processes and consequences of crop evolution and domestication, it is asserted that the judicious integration of in situ crop wild relatives into phytobiome research efforts presents a singularly powerful tool for separating signal from noise, thereby facilitating a more efficient means of identifying candidate plant-associated microbes with the potential for enhancing the immunity and fitness of crop species.



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.

Combining chloroplast and nuclear microsatellites to investigate origin and dispersal of New World sweet potato landraces

Comparison of nuclear and chloroplast data suggests that exchanges of clones and sexual reproduction were both important processes in landrace diversification in this clonally propagated crop, and suggests at least two independent domestications in Central/Caribbean America and in the north‐western part of South America.

Phylogeny and ancient DNA of Sus provides insights into neolithic expansion in Island Southeast Asia and Oceania

Archeological and genetic evidence shows these pigs were certainly introduced to islands east of the Wallace Line, including New Guinea, and that so-called “wild” pigs within this region are most likely feral descendants of domestic pigs introduced by early agriculturalists.

An Asian origin for a 10,000-year-old domesticated plant in the Americas.

It is suggested that the bottle gourd and the dog, two "utility" species, were domesticated long before any food crops or livestock species, and that both were brought to the Americas by Paleoindian populations as they colonized the New World.

The Introduction of Sweet Potato In Polynesia: Early Remains In Hawai'i.

With regard to introduction of sweet potato in Polynesia, Roger Green (2005) reviewed the evidence for sweet potato before and at the time of early European contact and proposed that it was secondary

The Sweet Potato in Oceania: a reappraisal

Although he originally intended to write a history of corn in Mexico, Arturo Warman's research and interests culminated in a broader global, social, and economic history with sparse attention to the Mexican roots of maize.

Beyond Kon-Tiki: did Polynesians sail to South America?

An ambitious drive is under way to settle a long-standing controversy among archaeologists and anthropologists. Considered the realm of crackpot theorists until recently, the idea of prehistoric

Agriculture and Sociopolitical Organization in New Guinea Highlands Prehistory

By the New Guinea Highlands we mean the high valleys within the central cordillera of the island between about 1300 and 2500 m, which are the home of relatively large populations living in deforested

Early Allelic Selection in Maize as Revealed by Ancient DNA

This work has analyzed three genes involved in the control of plant architecture, storage protein synthesis, and starch production from archaeological maize samples from Mexico and the southwestern United States to reveal that the alleles typical of contemporary maize were present in Mexican maize by 4400 years ago.
