L.S.,
Perhaps a very simple question, but why did (color) vision evolve?
Much is known and speculated on how from a rudimentary eye, vision and
color vision might have evolved, but it seems like a big energy
investment. Also the brain would have to adapt or be able to
interpreted the signals.
But still, why did (color) vision evolve? Wouldn't it be enough to see
in black and white?
I got this question from friend of mine and I was not able to answer
it! And on Google (Scolar) there only thing to find on how it evolved.
Can you point me to some articles, books or websites?
Color vision exists in insects, birds, and many fishes, in additional
to many mammals. You will notice that mammals that evolved to live in
nocturnal environments are mostly colorblind, including rodents, cats,
and canines. In dark nocturnal environments, everything looks black
+white, or shades of grey. OTOH, the world of daylight has natural
color everywheres, including blue sky and green foliage and colored
fruits and flowers. That should be a clue.
