I could be wrong in my use of "evolution" in the context of dog breeds. I'm fallible, unlike some here. I'm obviously capable of being sloppy.
Yet dogs may indeed stem from a common ancestor (ie- form a monophyletic
grouping) and evolution may have played a role via *natural* selection in
the early periods of dogs being associated with humans and diverging from
their wild ancestors. If modern breeding techniques, an artificial form of
stabilizing selection (once an AKC standard has been arrived at via
artificial directional selection) aren't evolutionary *per se*, this does
not detract much from my point that "dog" has more merit than "meme". Unlike
memes, we are pretty sure dogs exist.
Now when you are reserving the term "evolution" for natural selection are
you excluding other possiblitities such as genetic drift?
