Sure Marty, though I am not quite sure how one can determine whether or not such processes are guided vs. unguided in the same sense that one can’t quite say whether or not God influences hurricanes today.
Ah so that was our main problem. My apologies then for the confusion.
I’d also say that many old earth creationists (which is how I at least first heard the idea of progressive creation where God creates and intervenes sporadically–i.e. Reasons to Believe) would hold to the spontaneous materialization of species.
