[Taxacom] domesticates as subspecies?

Hi Fred and Jan,

        Well, the most recent study (published in Science last month) indicates that dogs were domesticated from a wild subspecies of European wolf.  There are presumably no longer any wild descendants of this population in existence.                        

        I see no problem using the trinomen, Canis lupus familiaris, for that subspecies (and its domesticated descendants).  Although humans have introduced domesticated dogs throughout the world, it still seems likely that it began as a geographical partition (which this latest study now indicates lived in Europe).  A weblink to one news story is given below.
