Dogs Domesticated for Food?

Man’s best friend is best served fried: A new study from the Royal Institute of Technology at Stockholm found that dogs in all regions of the world can be traced back to a single lineage, suggesting a single domestication event in southern China about 11,000 to 14,000 years ago. Dogs have long been on the menu in this part of China and, in fact, bones have been found with cut marks on them. Though this may have been their origin, they must have spread for other reasons, since most people do not eat them—likely, their work as guard and sled dogs.
