Biological How did dogs become our best friend?
At some point in our lives, we have all had a friendship with a dog.  So did the generations before us, as well as the generation before them.  When, exactly, did the friendship between dogs and humans take shape?  Research in this paper challenges current theories regarding the original location of wolf domestication. The authors sequenced DNA from mitochondrial genomes of both prehistoric canids and modern...
