EvC Forum: Can Domestic Selection cause Macroevolution?

Faith writes:

Domestic breeding makes use of the same principle of selection that Darwin merely applied to nature, only the one is applied intentionally by people, and the other by nature according to principles of survival. This much seems acceptable to both sides.

Faith writes:

all Darwin did was suggest how it might be possible, which was nothing more than observing that the principles of domestic breeding occur haphazardly in nature.
Strange though. All that shows is that Kinds vary in Nature too, only haphazardly. Nothing really terribly illuminating if you think about it. There's no more proof that macroevolution is possible by Natural Selection than by Domestic Selection. And really, that's all the ToE is, a suggestion of a possibility and it's now taken for gospel.
{ABE: In fact, it seems to me that the controlled forced speeded-up conditions of domestic breeding could prove macroevolution if it really occurs, but in fact what is observed to happen is the reverse of anything in the direction of macroevolution. That is, the more you select, the less genetic potential you have for further breeding, as I've pointed out many times before.}

*Words emboldened by me.

This thread occurred to me, while reading the Microevolution Vs Macroevolution thread, in which Faith equivocates the mechanisms of Domestic Selection (DS) and Natural Selection (NS) (See above quotes). She further goes on to say that it would seem that if Macroevolution did occur, then one would more likely observe it in DS than in NS; implying that this is proof against Macroevolution.

Now, it could be argued that DS is a form of NS (albeit corrupted), in that humans act as the “natural” selecting agent. However, could one say that NS is just DS in nature?
I don’t think so. This goes back to me calling DS corrupted. I say this because that, which is selected for in DS, is what humans regard as desirable; this is not the same as naturally advantageous. For this reason, one would not often find a heavily domesticated animal, surviving, uncared for, in the wild. Maybe I’m out of touch but I still haven’t heard of packs of wild Chihuahuas roaming the Mexican desert

. This is not to say that it doesn’t occur, but that it is a rare feat.

It is clear, that the outcomes of DS and NS are often at odds with each other. Why is it then that one would expect to observe Macroevolution emerging from DS?
I would actually think it less likely.
