without directly saying it, the report suggests (a) domestication of canines occurred earlier in Europe than elsewhere and (b) possibly very very much earlier, and (c) which MAY explain the cultural roots in some Asian societies where eating canines STILL has some adherents today (and was even more common in the past we modern humans know about)
And even some adherents in today's White House.
Eating dog was also practiced among precolumbian tribes, as a convenient meat supplement, since dogs were kept around to keep the coyotes and probably where applicable the wolves away, particularly in the night. They also served as a warning system for human intruders, which is still a major entry on the dog job description. :’)
