    The gray wolf isn't the origin of them, though. You wouldn't say C evolved from D or B or A.

    If Canis lupus is defined as all descendants of the last common ancestor of extant wolf lineages (defined in my example as B, C and D), and the domestic dog (defined in my example as A) is *also* a descendant of this last common ancestor then the only way to maintain C. lupus as a monophyletic taxon is to include the domestic dog within this species.

    The alternative is to reclassify every single lineage descending from this last common ancestor as a distinct species - this being the model which gives us C. lupus, C. chanco, C. pallipes, C. familiaris etc.

    Being included within a species and evolving from a species aren't the same thing, though.

    I think you are confusing wolf populations with wolf species.
