I want to know the answer to the following question:
What year was Canis familiaris listed under Canis lupus?
All the background I'm provided with is that "In 1982, the first edition of Mammal Species of the World listed Canis familiaris under Canis lupus with the comment: "Probably ancestor of and conspecific with the domestic dog, familiaris.". Is that enough to answer the question?
