Biblical Creationism Requires Evolution

I'd just like to say that this is my first post and while I haven't been in on the whole discussion thus far, I have tried to catch up on what has been discussed already.That having been said, I don't see how this supports macro-evolution for two reasons.One: The traits that are emerging WERE in the original population. The animals were bred specifically for their lack of agression and what came from that was a less agressive fox.Two: While the changes in phyical appearance may lead some to think that this is macro-evolution, it unfortunately does not prove that the foxes 'evolved' into dogs. They just became less agressive foxes, but as far as I can tell, they still retained the characteristics of a fox.
