@marduk: "Please share a model and/or theory that explains how phenomenal consciousness might emerge from non-preexisting, phenomenally conscious natural phenomena."
Does this rephrasing ask what you want it to? How phenomenal consciousness might emerge from an existing phenomenally conscious natural phenomena? I don't think so because it doesn't make sense.
Perhaps we could ask how a
mind might emerge from a phenomenally conscious natural substrate. Here you go. However, it's more a hypothesis than a model or theory.

Goes without saying, read the entire answers before forming conclusions. I'd be happy to discuss.
