The centre of origin of coconut extends from Southwest Asia to Melanesia. Nevertheless, its pre-Columbian existence on the Pacific coast of America is attested. This raises questions about how, when and from where coconut reached America. Our molecular marker study relates the pre-Columbian coconuts to coconuts from the Philippines rather than to those of any other Pacific region, especially Polynesia. Such an origin rules out the possibility of natural dissemination by the sea currents. Our… 

Coconuts in the Americas

It has been clearly established that the Portuguese introduced coconuts to the Cape Verde islands in 1499, and these supplied the Atlantic coasts and the Caribbean in the 1500s. By contrast, early

Tracing the origin of the coconut (Cocos nucifera L.)

The coconut palm (Cocos nucifera) and its fruit represent an important food and oil crop in tropical regions around the world; additionally, the entire plant provides myriad functions in the daily

Independent Origins of Cultivated Coconut (Cocos nucifera L.) in the Old World Tropics

TLDR
The coconut's domestication history and its population genetic structure as it relates to human dispersal patterns are investigated and two geographical origins of coconut cultivation are proposed: island Southeast Asia and southern margins of the Indian subcontinent.

Genome-wide diversity of northern South America cultivated Coconut (Cocus nucifera L.) uncovers diversification times and targets of domestication of coconut globally

TLDR
A dated evolutionary hypothesis for the independent origins of cultivated coconut globally were diversification between coconut populations has happened very recently and within few generations is proposed.

Genome-wide diversity of coconut from northern South America uncovers genotypes present in Colombia and strong population structure

TLDR
The results suggest that the Pacific coconuts of Colombia belong to the pre-Columbian population found on the Pacific coast of Panama and Peru, which has a lower genetic diversity and a higher rate of inbreeding than the Atlantic group.

Global Expansion of the Australian Biting Louse Heterodoxus spiniger Facilitated by Human Transport of Dog (Canis familiaris), and Implications for Prehistoric Cultural Interaction in Australasia

TLDR
An updated distribution of this notable ectoparasite is defined, and the evidence for transport of its hosts that may be responsible for its dispersal is explored, and a genomic approach is pursued in further investigation of this species’ history.

Genetic diversity and differentiation of the Hainan Tall coconut (Cocos nucifera L.) as revealed by inter-simple sequence repeat markers

TLDR
The phylogenetic clustering results indicated that the Hainan Tall population is domesticated separately from (and earlier than) other coconut accessions, and the differentiation existed within the Haitian Tall population.

The presence of coconut in southern Panama in pre-Columbian times: clearing up the confusion.

TLDR
This previously overlooked evidence confirms the pre-historical presence of coconut in Panama and Genetic data indicate that it must have been brought there directly or indirectly from the Philippines.

Phylogenetic Analysis of Seven WRKY Genes across the Palm Subtribe Attaleinae (Arecaceae) Identifies Syagrus as Sister Group of the Coconut

TLDR
A well-resolved and supported phylogeny of the Cocoseae subtribe is presented that robustly indicates a sister relationship between Cocos and Syagrus, and suggests that WRKY loci are informative markers for investigating the phylogenetic relationships of the palm family.

Genome Studies for Effective Management and Utilization of Coconut Genetic Resources

TLDR
This large genome was recently assembled into 16 pseudomolecules by anchoring it on a linkage map, allowing to identify key genes involved in the metabolism of the endosperm and in somatic embryogenesis.

History of coconut (Cocos nucifera L.) in Mexico: 1539–1810

TLDR
Historical knowledge has enabled the investigation of sites, dates and origins of the introductions, the initial areas of production, the economic importance of the cultivation and its diffusion during the colonial era to select key sites to gather samples to establish germplasm collections.

Genetic diversity in coconut (Cocos nucifera L.) revealed by restriction fragment length polymorphism (RFLP) markers

TLDR
A study of the genetic diversity in coconut by RFLP analysis was performed in 100 individuals representing 10 Tall and seven Dwarf local populations or 'ecotypes' from various geographical origins and the legitimacy of two hybrids between ecotypes was confirmed and maternal inheritance of mitochondrial genome was observed.

The dispersal of the coconut: did it float or was it carried to Panama?

TLDR
A stochastic simula- tion model of the winds, currents and islands of the Pacific Ocean tests the hypothesis of trans-Pacific drift dispersal and suggests that the probability of coconuts drifting unaided to the west coast of Panama while remaining viable is extremely low.

The evolution, dissemination and classification ofCocos nucifera L.

TLDR
A classification system in which the varieties are identified by the degree of introgression (based in the first place on fruit component analysis) is described, which allows a suggestion to be made concerning the location of the much-debated centre of origin for cocos nucifera.

Radiocarbon and DNA evidence for a pre-Columbian introduction of Polynesian chickens to Chile

TLDR
A radiocarbon date and an ancient DNA sequence from a single chicken bone recovered from the archaeological site of El Arenal-1, on the Arauco Peninsula, Chile, provide firm evidence for the pre-Columbian introduction of chickens to the Americas, and strongly suggest that it was a Polynesian introduction.
