“…Evidences are also controversial as to the timing and places where chicken domestication first occurred (Zeuner, 1963 ; Crawford, 1984 ; West and Zhou, 1988 ; Fumihito et al, 1996 ; Liu et al, 2006 ; Xiang et al, 2014 , 2015 ; Peters et al, 2015 ). A study on mitochondrial DNA suggests multiple centers of chicken domestication (Liu et al, 2006 ) from which chicken dispersed to different parts of the world through humans' influence.…”

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

The red junglefowl Gallus gallus is the main progenitor of domestic chicken, the commonest livestock species, outnumbering humans by an approximate ratio of six to one. The genetic control for production traits have been well studied in commercial chicken, but the selection pressures underlying unique adaptation and production to local environments remain largely unknown in indigenous village chicken. Likewise, the genome regions under positive selection in the wild red junglefowl remain untapped. Here, using the pool heterozygosity approach, we analyzed indigenous village chicken populations from Ethiopia, Saudi Arabia, and Sri Lanka, alongside six red junglefowl, for signatures of positive selection across the autosomes. Two red junglefowl candidate selected regions were shared with all domestic chicken populations. Four candidates sweep regions, unique to and shared among all indigenous domestic chicken, were detected. Only one region includes annotated genes (TSHR and GTF2A1). Candidate regions that were unique to each domestic chicken population with functions relating to adaptation to temperature gradient, production, reproduction and immunity were identified. Our results provide new insights on the consequence of the selection pressures that followed domestication on the genome landscape of the domestic village chicken.

“…In turn, Peters et al (2015) also raised several questions: improper incorporation of the primer sequence, unsuitability of the climatic condition of northern China for red junglefowl, difficulty of ancient DNA sequence amplification based on the thermal age calculation, suspicion on the morphological identification of the analyzed samples, and possibility of contamination from the later cultural deposits. Xiang et al (2015a) contradicted these questions and concluded “further discussions confirm early Holocene chicken domestication in northern China” in the title of their reply letter.…”

“… Xiang et al (2014) analyzed at least two canid bones ( Peters et al, 2015 ), more specifically the right canid metacarpi ( Eda et al, 2016 ), and demonstrated them as “typical ancient chicken bones unearthed in northern China” ( Xiang et al, 2014 ). Although Xiang et al (2015a) insisted that they did not succeed in identifying the species of the canid bones and their identity has no bearing on the conclusions drawn by Xiang et al (2014) , Eda et al (2016) stated that these bones should be considered “typical” and indicative of the reliability of the samples used by Xiang et al (2014) .…”

“…3 A proposed earlier event of domestication around 8000 BCE in northern China, based on mtDNA analysis, 5 remains debated. [4][5][6][7] The main ancestor of domestic chicken is the red junglefowl (Gallus gallus), but a contribution from at least two other Gallus species (Grey junglefowl: Gallus sonneratii and Sri Lankan junglefowl: Gallus lafayetii) has been postulated. [8][9][10] Several "domestication centres" of chicken have been identified in South and South-East Asia.…”

The domestication of the fowl resulted in a large diversity of integumental structures in chicken breeds. Several integumental traits have been investigated from a developmental genetics perspective. However, their distribution among breeds and their developmental morphology remain unexplored. We constructed a discrete trait‐breed matrix and conducted a disparity analysis to investigate the variation of these structures in chicken breeds; 20 integumental traits of 72 chicken breeds and the red junglefowl were assessed. The analyses resulted in slight groupings of breed types comparable to standard breed classification based on artificial selection and chicken type use. The red junglefowl groups together with bantams and European breeds. We provide new data on the red junglefowl and four chicken breeds, demonstrating where and when variation arises during embryonic development. We document variation in developmental timing of the egg tooth and feather formation, as well as other kinds of developmental patterning as in the anlagen of different type of combs. Changes in epithelial‐mesenchymal signaling interactions may drive the highly diverse integument in chickens. Experimental and comparative work has revealed that the cranial neural crest mesenchyme mediates its interactions with the overlying epithelium and is the likely source of patterning that generates diversity in integumental structures.
