The origin of the domestic dog (''Canis lupus familiaris'' or ''Canis familiaris'') is not clear. Whole genome sequencing indicates that the dog, the gray wolf, and the extinct Taymyr wolf diverged at around the same time 27,000–40,000 years before present.〔 These dates imply that the earliest dogs arose in the time of human hunter-gatherers and not agriculturists.〔 Modern dogs are more closely related to ancient wolf fossils that have been found in Europe than they are to modern gray wolves,〔 with nearly all genetic commonalities with the gray wolf due to admixture,〔 but several Arctic dog breeds have commonalities with the Taymyr wolf of North Asia due to admixture.〔 |2= }} |2= }} }} }} }} }} }} }} }} ==Dog evolution== Dog evolution (from the Latin ''ラテン語:evolutio'': "unrolling")〔 is the biological descent with modification〔 that led to the domestic dog. This process encompasses small-scale evolution (changes in gene frequency in a population from one generation to the next) and large-scale evolution (the descent of different species from a common ancestor over many generations).〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「origin of the domestic dog」の詳細全文を読む スポンサード リンク
