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")
Dog type the written standard and awards are based on how closely the dog resembles the standard. Note 2. Many modern breeds of dogs still use the names of early types, although they may or may not resemble the old types. Note 3. Early attempts to categorize dogs as species of "Canis" are described by Carl Linnaeus in Systema naturae, 1758, Gmelin in 1788, Kerr in 1792. Dog type Dog types are broad categories of dogs based on form, function or style of work, lineage, or appearance. In contrast, modern "dog breeds" are particular breed standards, sharing a common set of heritable
