Background Hybridisation and introgression play key roles in the evolutionary history of animal species. They are commonly observed within several orders in wild birds. The domestic chicken Gallus gallus domesticus is the most common livestock species. More than 65 billion chickens are raised annually to produce meat and 80 million metric tons of egg for global human consumption by the commercial sector. Unravelling the origin of its genetic diversity has major application for sustainable… 

Whole-Genome Resequencing of Worldwide Wild and Domestic Sheep Elucidates Genetic Diversity, Introgression, and Agronomically Important Loci

A comprehensive genome resource for wild ovine species, landraces and improved breeds of domestic sheep, comprising high-coverage whole genomes of 810 samples from 7 wild species and 158 diverse domestic populations, finds two main waves of migrations across the Eurasian Steppe and the Iranian Plateau in the Early and Late Bronze Ages.

863 genomes reveal the origin and domestication of chicken

This study suggests that domestic chickens were initially derived from the RJF subspecies Gallus gallus spadiceus whose present-day distribution is predominantly in southwestern China, northern Thailand and Myanmar.

Large-scale genomic analysis reveals the genetic cost of chicken domestication

A new landscape of demographic history and genomic changes associated with chicken domestication is revealed and insight is provided into the evolutionary genomic profiles of domesticated animals managed under modern human selection.

Researching on the fine structure and admixture of the worldwide chicken population reveal connections between populations and important events in breeding history

It is found that the genomes of modern chicken stocks used for meat production both in eastern (Asia) and western (Europe/US) agriculture are dominated by contributions from heavy Asian breeds.

Unveiling new perspective of phylogeography, genetic diversity, and population dynamics of Southeast Asian and Pacific chickens

Analysis of mitochondrial DNA control region sequences revealed evidence of a new divergent matrilineage in haplogroup V, which exemplified dispersal patterns to the ISEA, and thereafter the island clade diversified as a distinct group.

The wild ancestors of domestic animals as a neglected and threatened component of biodiversity

Comparative behavioral, ecological, and genetic studies of ancestral‐type, feral, and domestic animals should be prioritized to establish the contemporary status of the former.

Domestic chicken diversity: Origin, distribution, and adaptation.

The role of human and natural selection in shaping the diversity of the species is highlighted and a few examples of knowledge gaps are provided that may be the focus of future research.

Revisit the Development of Native Indonesian Chickens from Red Jungle Fowls (Gallus gallus bankiva) to Commercial Chickens

Kampung chicken which is one of native Indonesian chickens has been domesticated from the ancestor of Red Fowl Jungle, and developed by the village community from generation to generation through an

The Chicken Pan-Genome Reveals Gene Content Variation and a Promoter Region Deletion in IGF2BP1 Affecting Body Size

The first chicken pan-genome constructed using 664 individuals is presented, which identified an additional approximately 66.5-Mb sequences that are absent from the reference genome (GRCg6a), and improves the understanding of chicken genome diversity and provides materials to unveil the evolution history of chicken domestication.



Whole-Genome Resequencing of Red Junglefowl and Indigenous Village Chicken Reveal New Insights on the Genome Dynamics of the Species

This work analyzed indigenous village chicken populations from Ethiopia, Saudi Arabia, and Sri Lanka, alongside six red junglefowl, for signatures of positive selection across the autosomes to provide new insights on the consequence of the selection pressures that followed domestication on the genome landscape of the domestic village chicken.

Molecular evidence for hybridization of species in the genus Gallus except for Gallus varius.

A phylogenetic tree for fowl including chicken in the genus Gallus and based on mitochondrial D-loop analysis further supports the hypothesis developed from morphology and progeny production that red

Multiple maternal origins of chickens: out of the Asian jungles.

Whole-genome resequencing reveals loci under selection during chicken domestication

The use of massively parallel sequencing is described to identify selective sweeps of favourable alleles and candidate mutations that have had a prominent role in the domestication of chickens and their subsequent specialization into broiler (meat- producing) and layer (egg-producing) chickens.

Signatures of selection and introgression in the genus Gallus

The results indicate that the genetic make-up of the domesticChicken is rather complex with multiple species and subspecies influences and future study should consider investigating the genome-wide analysis of introgression from the green junglefowl into the domestic chicken.

Adaptation and possible ancient interspecies introgression in pigs identified by whole-genome sequencing

An exceptionally large (14-Mb) region with a low recombination rate on the X chromosome is found that appears to have two distinct haplotypes in the high- and low-latitude populations, possibly underlying their adaptation to cold and hot environments, respectively.

Genetic analysis of local Vietnamese chickens provides evidence of gene flow from wild to domestic populations

The large number of alleles shared exclusively between Ha Giang chickens and junglefowl, as well as the results of a Bayesian clustering analysis, suggest that gene flow has been taking place from Junglefowl to Ha Giag chickens.

Genetic features of red and green junglefowls and relationship with Indonesian native chickens Sumatera and Kedu Hitam

The data indicate that wild junglefowls have retained their genetic identity, but the Indonesian and American breeds have not, and the Black Sumatra and Black Java are now closely related to each other, suggesting loss of genetic identity after export to the United States.

Comparative mitochondrial genomics and phylogenetic relationships of the Crossoptilon species (Phasianidae, Galliformes)

The mito-phylogenomic analysis supports the monophyly of Crossoptilon and its closer relationship with Lophura, and shows that C. harmani is much more closely related to C. crossoptilon.

A phylogenetic supertree of the fowls (Galloanserae, Aves)

The supertree represents one of the most comprehensive estimates for the Anseriformes and Galliformes to date, including 376 species, and indicated that more than 30% of the polytypic genera examined were not monophyletic, suggesting that results from genus‐level comparative studies using the average of the constituent species’ traits should be interpreted with caution until analogous species‐ level comparative studies are available.
