DNA Shows Ancient Siberians Domesticated Dogs, Who Then Helped Settle America February 05, 2021 13:16 GMT Share share Print Scientists have long sought an indisputable link showing when humans first domesticated dogs, steering a few receptive gray wolves descendants toward lives as lapdogs. The origins of their domestic relationship is one of the most hotly debated questions around dogs undying loyalty to their masters and humankind’s unparalleled reliance on dogs to get a leg up on other predators in a frequently hostile environment. Now, a team of interdisciplinary researchers has used DNA and other evidence to assert a tandem movement in and then beyond northeastern Siberia at a key stage of human and canid development late in the last Ice Age. ....
Dogs successfully migrated to the Americas about 10,000 years ago, according to a new study. That s a long time ago but still thousands of years after the first human migrants crossed the land bridge from Siberia to North America. Dogs have been associated with humans in findings from 11,000 to 16,000 years ago. Did humans not bring them at first? Did they die? Ancient dogs split off from wolves likely because they learned to tolerate human company and as part of selective evolution - humans let the ones that protected them and were friendly stick around. Dogs benefited from the association: They gained access to new food sources, enjoyed the safety of human encampments and eventually traveled the world with their two-legged masters. Dogs were also beasts of burden and sometimes food, particularly on special occasions - that meant in times of extreme hunger too. ....
