Title: Origin of the domestic dog
Content: the indigenous peoples of Siberia, East Asia, North America, and Australia. The domestic dog was the first species and the only large carnivore to have been domesticated. Over the past 200 years, dogs have undergone rapid phenotypic change and were formed into today's modern dog breeds due to artificial selection imposed by humans. These breeds can vary in size and weight from a teacup poodle to a giant mastiff. The skull, body, and limb proportions vary significantly between breeds, with dogs displaying more phenotypic diversity than can be found within the entire order of carnivores. Some breeds demonstrate outstanding skills

Content: fits the available evidence, which is that an initial wolf population split into East and West Eurasian wolves, these were then domesticated independently before going extinct into two distinct dog populations between 14,000-6,400 years ago, and then the Western Eurasian dog population was partially and gradually replaced by East Asian dogs that were brought by humans at least 6,400 years ago. Domestic dogs have been selectively bred for millennia for various behaviors, sensory capabilities, and physical attributes. Modern dog breeds show more variation in size, appearance, and behavior than any other domestic animal. Dogs are predators and scavengers, and like

Title: Origin of the domestic dog
Content: a direct ancestor). The data from this study indicated a European origin for dogs that was estimated at 18,800–32,100 years ago based on the genetic relationship of 78% of the sampled dogs with ancient canid specimens found in Europe. The data supports the hypothesis that dog domestication preceded the emergence of agriculture and was initiated close to the Last Glacial Maximum when hunter-gatherers preyed on megafauna. The study found that three ancient Belgium canids (the 36,000 YBP "Goyet dog" cataloged as "Canis" species, along with Belgium 30,000 YBP and 26,000 years YBP cataloged as "Canis lupus") formed an ancient clade

Content: at that time. These also include the 36,000-year-old "Goyet dog" and the 33,000-year-old "Altai dog". Later studies suggested that it was possible for multiple primitive forms of the dog to have existed, including in Europe. European dog populations had undergone extensive turnover during the last 15,000 years that has erased the genomic signature of early European dogs, the genetic heritage of the modern breeds has become blurred due to admixture, and there was the possibility of past domestication events that had gone extinct or had been largely replaced by more modern dog populations. In 2016, a study compared the mitochondrial

Title: Origin of the domestic dog
Content: Eurasian groups; these, before going extinct, were domesticated independently into two distinct dog populations between 14,000 and 6,400 years ago. The Western Eurasian dog population was partially and gradually replaced by East Asian dogs introduced by humans at least 6,400 years ago. Six million years ago, towards the close of the Miocene era, the earth's climate was gradually cooling and this led to the glaciations of the Pliocene and the Pleistocene – the Ice Age. In many areas, forests and savannahs were replaced with steppe or grasslands and only those creatures that could adapt survived. In southern North America, small
