Thanks for the kind words - however, I have occasionally been given to outbursts of exasperation and sarcasm - especially about the denial of evolution - so I'm not sure I deserve it.
In this discussion though, I really want to try to understand how the emergence of all the different "types" could happen at different points in time if each type were specifically designed by God. And if they did indeed emerge as God's specific creations but at different times, how is this not divine intervention of the same watch-winding variety that Newton thought was necessary to keep the stars and planets in their proper places? (Not being rude - just pointing out that whilst we might not have a perfect scientific explanation of exactly how evolution proceeded at every step, we might be on slippery ground assuming divine machinations just because we lack certain knowledge).
Incidentally, all the different breeds of domestic dog are indeed considered to be one species, with taxonomical classification of either canis familiaris or canis lupus familiaris - canis lupus being the designation for the gray wolf which is (one of) the non-domesticated descendant of the species thought to be the common ancestor of both domestic dogs and wild wolves that exist today (though there is emerging evidence that the evolutionary lineage of the domestic dog is not that clear cut after all). In any case, when man and dog became best friends, in evolutionary terms, they each became a very significant, perhaps the most significant 'other' part (apart from their own species), of the others environment, the proximity of each contributing to the evolutionary success of the other. Their barking might annoy us when it wakes us up in the night, but its entirely possible IMO that the dog's acuity of hearing and territorial nature might have been the very thing that made the human environment secure enough to permit campfire philosophizing to begin. In evolutionary terms, it might even be truer, to some extent, to suggest that 'dog made man' then it is to suggest that 'God made man'. Again, not being rude or sarcastic, just pointing out the implications of an undeniable evolutionary relationship between dog and man that long predates any evidence of the human notion of an Almighty Creator.
