Scientists discover the oldest color on the planet – EnLineaDirecta.info

Scientists from the National University of Australia (ANU) extracted the oldest intact pigment ever recorded, a bright pink color from the Sahara Desert. Samples were taken from Taoudeni Basin rocks in Mauritania, Africa, and date back to 1,100 million years ago.

The research, published in the scientific journal PNAS, confirms the discovery of pigments 500 000 years older than all the others. discovered earlier, according to scientist Nur Gueneli of the School of Earth Sciences of the ANU, who led the study.

"Bright pink pigments are molecular chlorophyll fossils that have been produced by ancient photosynthetic organisms that inhabited an ocean." After crushing the collected stones, the scientists at ANU, with the Support from the Geoscience Australia Institute and other US and Japanese researchers, noted that the pigment is bright pink colrum in its diluted form and shown in red blood or dark purple in its concentrated form.

Why? the animals did not exist?
"Accurate pigment badysis confirmed that small cyanobacteria dominated the base of the food chain in the oceans 1,000 million years ago, which explains why animals did not exist at that time" Gueneli said. his colleagues at ANU, Jochen Brocks, added that large animals, including humans, began to flourish once cyanobacteria were replaced in the oceans by seaweed – "a source of much food richer "- about 650 million years.
