Flowers with various colors have added to the beauty of the world. But apparently it is not always the case. Existing fossils show flowers in this world were very simple without much pigmentation.
Scientists believe that the flowers were only yellow or pale green in color before they began to evolve, so that the colors were striking more than 100 million years ago.
The evolution of these flowers occurs to attract pollinating animals, namely bees, whose food is nectar and pollen, and a number of birds that eat nectar.
According to Associate Professor Adrian Dyer from RMIT University, bees and birds differ from the way humans see the world. Therefore many flowers that change their color adjust to the visual system of bees and birds.
