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 view holds that domestication as a process that is difficult to define. The term was developed by anthropologists with a human-centric view in which humans took wild animals (ungulates) and bred them to be "domestic", usually in order to provide improved food or materials for human consumption. That term may not be appropriate for a large carnivore such as the dog. This alternate view regards dogs as being either socialized and able to live among humans, or unsocialized. There exists today dogs that live with their human families but are unsocialized and will threaten strangers defensively and aggressively no different
