Evolution always must begin with a preexisting platform -- so to speak -- and builds on

Yes, I'd heard the story about the purple bacteriodopsin that used the middle part of the
visible spectrum. But the implication is that these bacteria were shading the bacteria or
algae that developed chlorophyll. Which might be true, but they've not been shading them
for the last billion years or so since plants came onto the land. So I don't see it has a
local optimum. There's a big chunk of spectrum right there adjacent to the spectrum being
used. There doesn't seem to be any significant barrier.
