(a) Haplogroup A. (b) Haplogroup B. (c) Haplogroups CD, Y, Z, J, and an unclassified haplotype, Hap_38. (d) Haplogroups H, I, K, X, and W. (e) Haplogroup E. (f) Haplogroup F. Haplotypes that were found in the present study and representative haplotypes reported by Miao et al.5 are shown by magenta and yellow circles, respectively. Black nodes are the inferred intermediate haplotypes. The number of bars on the lines, which link haplotypes, represent the number of nucleotide substitutions that occurred between the haplotypes for comparison (Adopted from Hata et al., 2021) 6 Implications for Evolutionary Biology and Agriculture 6.1 Broader lessons on animal domestication processes The domestication and breed changes of domestic chickens are important examples for studying the mechanisms of animal domestication. Genomic and mitochondrial DNA studies have shown that domestic chickens mainly come from red pheasants (Gallus gallus). However, during the domestication and diffusion process, the grey
