The re-analysis of an ancient jawbone reveals humans living in Central America domesticated dogs 12,000 years ago. It was previously believed this happened 9,000 to 10,000 years ago. ....

While many people associate the region that is now in Russia with forbidding cold today, climate data as well as archaeological and DNA evidence show that this was where horses, mammoths and other prey animals found enough to eat, which attracted humans and other carnivores. Hemmed in by worse conditions, the humans, some of them the ancestors of Native Americans, were isolated for thousands of years. So were wolves. It is there and then that dogs were first domesticated, according to a new hypothesis from a group of archaeologists and ancient DNA experts who specialize in the deep history of humans and canines. They published their analysis on Monday in Proceedings of the National Academy of Sciences. ....
