Many animals can see a much broader range of colors than we
can, which helped them to survive. They can see other colors because they have
more cones in their eyes then we do. We only have three, short medium and long,
and other organisms can have many more and see a wide variety of colors that we
can even imagine. Seeing other colors is an important adaptation for most
animals. For example the bumble bee has coevolved with flowers to form a mutual
symbiotic relationship where the bees pollinate the flowers and the flowers
feed the bees nectar. This occurred because bees have compound eyes that allow
them to see ultraviolet light and so the flowers adapted by using ultraviolet
pigments to lure the bees in. Flowers use unique patterns that act as “landing
strips” to direct them to the center of the flower and show the bees where the
pollen and nectar are so they will come and pollinate them. So every flower has
a hidden pattern that we cannot see.
