Totally agree, thanks for a great post.
As to how or why God might intervene in any "natural" selection, if we simply remember that God's Plan (word) was with God from the beginning, indeed, the Plan itself IS God, then it seems to me irrelevant whether God Himself makes "natural" selections, or whether the eventual outcome of those selections is predetermined by God's original Plan.
Does that help?
It's not irrelevant, if our desire is to fully understand the entire process by which the Almighty's grand biological "experiment" is being conducted.
And I disagree the out come is predetermined. It's apparent both in word and in nature that it isn't. God wasn't satisfied with his previous results and wiped out many species according to the word. Likewise, physical evidence of mass extinctions is fact.
Summarizing Einstein: our understanding is only what we are able to perceive with our frail and feeble minds." It does all make for interesting study and lively debate and the rest I pretty much agree with you on. :-)
