Thou I am honored, I’m pretty sure this is the comment @Art meant to link. 😀

I see Matzke is already co-author with Baker on a paper using that approach to understand how ion-selectivity evolves (how the flagellum can evolve by mutations and selection to switch between sodium ions, or protons, to power movement):
