Researchers found the oldest identified coloration produced by a residing organism. It’s over one billion years outdated, and coloured vibrant pink. Researchers found the colour in cyanobacteria fossils preserved in rocks within the Sahara Desert. When scientists extracted pigment from the micro organism, they discovered darkish pink and deep purple spots in concentrated type. Distilled, it turned vibrant pink.

“The bright pink pigments are the molecular fossils of chlorophyll that were produced by ancient photosynthetic organisms inhabiting an ancient ocean that has long since vanished,” defined Dr. Gueneli, a researcher from the ANU Research School of Earth Sciences. It’s doubtless that the micro organism dominated historical oceans for a whole lot of tens of millions of years, maybe casting a pink tint to the ocean itself. The pink-producing cyanobacteria are so outdated that even algae, one of many oldest types of life on earth, was hardly ever discovered. “This was actually an alien world,” research co-author Jochen Brocks told LiveScience.
A couple of hundred million years later, algae would begin to multiply, and begin to type the start of a meals net that may finally result in the evolution of animals. Until then, pink cyanobacteria dominated the oceans.
It took a really fortunate collection of occasions to protect the chlorophyll: after lifeless natural matter sunk to the seafloor, it needed to settle in a spot the place it stays remoted from publicity to oxygen. Not solely that, however the rock that preserved in needed to survive a billion years in a single piece.
