It was found the oldest color in the world. Do you know what it is?

The world's oldest color is more than a billion years old and is the color of flamingos, the color of cotton candy or the color that one badociates with chewing gum. gum – pink. Researchers from the University of Australia (ANU) found pigments of this color in the subsoil of Mauritania, glued to rocks buried under the sands of the Sahara

Nur Gueneli, who found the color after crushing the rock and isolated the pigments, is based on chlorophyll molecular fossils, produced by photosynthetic organisms that inhabited an ocean disappeared for millions of years. The ANU scientist claims that prior to this discovery, the first known color was still less than 500 million years old than this pink, which acquires a blood-red color when it is more concentrated .

interesting is that this discovery allows us to know more about a period of life on the planet during which there were no animals. Jochen Brocks, one of the investigators involved in the project, told the BBC that the discovery of this color is the equivalent of "finding a piece of fossilized dinosaur skin that had retained its color. ;origin". The teacher was particularly enthusiastic about what this discovery means. "We find that they are molecules – not a huge creature but microscopic organisms because there were no animals at that time yet."

Although the Earth At 4.6 billion years ago, the species we call today "animals" only appeared 600 million years ago. By badyzing the color fragments in more detail, it became clear to researchers that it was cyanobacteria, such photosynthetic organisms. "Cyanobacteria dominated the base of the food chain in the oceans a billion years ago and that 's why we did not find animals, it' s There was not enough nutritious food that could lead to their evolution. "

disappeared 650 million years ago, and it is at this time that the algae began to spread very rapidly. "Algae were the injection of energy that was necessary for the evolution of more complex ecosystems, where huge creatures, including, could take revenge," he said. Explain.
