adaptation in flowers or in the eye's of bees?

Just curious: Did bees (or any other nectar sucking animals) evolve eyes to easier find the flower of desire, or did plants evolve colors to attract the desierd animals for fertilization?

What was first? Egg or chicken? Good question ;)

For the answer you had to look into the genomes, when did these evolve. My guess would be, that plants evolved later, because it's IMHO simpler to get new pigment in plant, than in eye... Just compare, how many pigments in flowers there are, but (at least in mammals, I don't know, how is it in insect) there are only two, rarely three pigments for detection of different lights ;)

Cis or trans? That's what matters.

Imagine a system where flowers that had an overproduction of a certain pigment were easier for food-seeking bees to find, and that stickier pollen variants would spread with the bees. That would start a progression that would favor more "stand-out" flowers as well as bees more attuned to those color variants.
