Origin of the domestic dog haplotype designated as S805 (28,000 YBP) from the Yana River was one mutation away from another haplotype S902 (8,000 YBP) that represents Clade A of the modern wolf and domestic dog lineages. Closely related to this haplotype was one that was found in the recently-extinct Japanese wolf. Several ancient haplotypes were oriented around S805, including "Canis c.f. variabilis" (360,000 YBP), Belgium (36,000 YBP – the "Goyet dog"), Belgium (30,000 YBP), and Konsteki, Russia (22,000 YBP). Given the position of the S805 haplotype on the phylogenetic tree, it may potentially represent a direct link from the progenitor (including "Canis c.f. variabilis")
Origin of the domestic dog dogs in the early stages of domestication might be indistinguishable from wolves. According to indigenous North Americans, over the past 20,000 years the canids living with them were wolves that could not be distinguished as dogs. The problem in attempting to identify when and where domestication occurred is the possibility that the process of domestication occurred in a number of places and at a number of times throughout prehistory. Early dog remains have been found in different parts of the world. This suggests that dog domestication may have taken place in different regions independently by hunter-gatherers, in some cases at
