dhw: And I suggest that constant change runs contrary to the hypothesis that he started out with the sole purpose of creating a single species. But we have been over this a thousand times, and so if you will stop telling us that the higgledy-piggledy bush was God’s method of fulfilling his sole purpose of producing the human brain, I will stop proposing alternative interpretations of the bush and your God’s intentions.

Sorry, your objection has holes. Evolution is change. In the case of the human evolutionary bush, the brain kept growing and developing more advanced functional hominins until humans appeared. Looks like a teleologic plan to me. Perhaps God set a genetic explosion in motion and let it run its course. Just as logical has your stories.
