Scientists show that dogs were domesticated twice

The question, ‘Where do domestic dogs come from?’, has vexed scholars for a very long time. Some argue that humans first domesticated wolves in Europe, while others claim this happened in Central Asia or China. A new paper, published in Science, suggests that all these claims may be right. Supported by funding from the European Research Council and the Natural Environment Research Council, a large international team of scientists compared genetic data with existing archaeological evidence and show that man’s best friend may have emerged independently from two separate (possibly now extinct) wolf populations that lived on opposite sides of the Eurasian continent. This means that dogs may have been domesticated not once, as widely believed, but twice.

Dogs domesticated themselves. The wolves just started hanging around the hairless apes who gave them charred bones.

Please do a dachshund-friendly version of this.

He sometimes appears not to have been domesticated at all, let alone twice.

An Oxford tutorial may help...

Fascinating! It is interesting to imagine our human ancestors interacting with the wolf. I imagine the domestication began much like the more than 50 years of selective breeding that Dmitri Belyaev did of wild foxes, which resulted in there being Russian domestic foxes.
I can envision certain wolves had less fear of humans and perhaps more dependence on human camps for scraps of food. These 'camp follower' wolves bred with wolves of similar temperament and there evolved to be wolves that lived symbiotically with humans. All it would take then, would be a litter of orphaned pups adopted by the humans and the human directed breeding of wolves/dogs began. It is not surprising that this relationship began in more than one location.

Given native americans had their own dog breeds (which are no longer in existence) that means dogs evolved at least three times.
Given migration to the new world predates old world dog domestication.

If humans came to the American continent over the land bridge then why is it even crazy that 2 groups of dogs could have been domesticated. The humans could have came over with that knowledge already and just did it with western wolves. Correct me if I'm way off. I may be
