Dog domestication happened many times, but most didn’t pan out
From ArsTechnica.com:
Between 8,000 and 12,000 years ago, people in Alaska kept reinventing dogs with mixed results.
The dogs that share our homes today are the descendants of a single group of wolves that lived in Siberia about 23,000 years ago. But for thousands of years after that split, the line between wolf and dog wasn’t quite clear-cut. A recent study shows that long after dogs had spread into Eurasia and the Americas, people living in what is now Alaska still spent time with—and fed—a bizarre mix of dogs, wolves, dog-wolf hybrids, and even some coyotes.
