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")
Ticks of domestic animals classification of the Acari, including the two families of ticks of importance to domestic animals is in the article Mites of livestock. "Amblyomma" species are widespread on domestic animals throughout tropical and subtropical regions. Typical "Amblyomma" species are: "Amblyomma americanum", the lone star tick of southern and eastern USA; "Am. cajennense", the Cayenne tick of South America and southern USA; "Amblyomma variegatum", the bont tick of Africa and the Caribbean (see Gallery below for photograph of female and male). A typical "Rhipicephalus" species is "Rhipicephalus sanguineus", the tropical dog tick, specialized to feed only on dogs. It is distributed globally
