Just pondering that evolutionary adaptation is fascinating. I wonder if it came
about from the fact that we descended from tree-or-forest-dwelling animals,
where the predominant color was green? Not that the *entire* earth was
forested, but a good portion of it.  Does it also mean that we humans can now
see subtle gradations of green better than subtle gradations of red or blue?
