4 lis 2020 · A genetic analysis revealed that by the end of the last ice age—around 11,000 years ago—there were a least five distinct lineages that gave rise to dogs in New Guinea, the Americas, northern...
7 lip 2018 · The first appearance of dogs in the North American archaeological record occurs ~6,000 years after the earliest evidence of human activity (4, 11). In addition, our molecular clock analysis indicates that the PCD lineage appeared ~6,500 years after North American human lineages (Fig. 1b) (10).
In 2021, a literature review of the current evidence infers that domestication of the dog began in Siberia 26,000-19,700 years ago by Ancient North Eurasians, then later dispersed eastwards into the Americas and westwards across Eurasia.
2 lut 2021 · The long evolutionary journey that created modern humans began with a single step—or more accurately—with the ability to walk on two legs. One of our earliest-known ancestors, Sahelanthropus,...
18 lip 2017 · Dogs most probably evolved from wolves at a single location about 20,000 to 40,000 years ago, a study suggests.
22 lis 2021 · None of the earliest Americans, who migrated to North America from Siberia across the land mass of Beringia, were associated with canids, either. An 18,000-year-old puppy, dubbed Dogor...
6 lip 2018 · Dogs were present in the Americas before the arrival of European colonists, but the origin and fate of these precontact dogs are largely unknown. We sequenced 71 mitochondrial and 7 nuclear genomes from ancient North American and Siberian dogs from time frames spanning ~9000 years.
