Purported remains of "Paleolithic dogs" have been reported from several European archaeological sites dating to over 30,000 years ago. Their status as domesticated is highly controversial, with some authors suggesting them to be the ancestors of the domestic dog or an extinct, morphologically and genetically divergent wolf population.
