Was the world ever a ‘purple’ color?

What is the color of earth? In the film taken from space, it is seen that most of the earth is blue (water) and some parts are green (soil and plants). But the color of the world was not always there. Rather, the color of the world was violet!

The world was purple, the theory that Molecular Biology Professor Shiladitya Das Sharma and Astrologist Edward Shuterman They claim that there was no existence of green chlorophyll in the world at one time, but there were all the unicellular creatures that could create energy from the light on which the light was showing purple. It was the position of these creatures in the whole world that the world was considered to be purple.

Their research data is published in the International Journal of Astrophysiology. Researchers claim that a chromoprotein called retinal can produce energy in the presence of light and its color is violet. Chlorophyll can produce more energy, it can not be retinal. But before the existence of chlorophyll, the unicellular organisms created the power. But they could not make oxygen or carbohydrates.

Even the one-organisms that use retinal are still on the earth. Especially in different seas it has its existence. It can not be sure that there was a time when this purple unicorn was on the earth. However, only 400 million years ago, after the origin of life on Earth, they are likely to be seen. Then again 230 million years ago, the earth was filled with green-green amounts of chlorophyll, so that the number of purple creatures decreased. Green organisms produce enough oxygen, it is called The Great Oxygenation Event.

At first, violet microorganisms, then green molecule, and at one stage more complex eukaryotic algae and plants originate in the world. At some time the purple and green microbes lie alongside. Researcher Das Sharma thinks that retinal and chlorophylls evolve with the help of this one.
