MELBOURNE: Scientists have discovered the oldest colors of the geological disk – bright pink pigments, aged 1.1 billion years old and extracted from the deep rocks of the Sahara Desert in Africa.

Pigments extracted from the marine black shales of the Taoudeni Basin in Mauritania, West Africa, were more than half a billion years older than previous pigment discoveries, said Nur Gueneli of the Australian National University (ANU).

"Bright pink pigments are the molecular fossils of chlorophyll that have been produced by ancient photosynthetic organisms inhabiting an ancient ocean that has long since disappeared," Gueneli said.

<p>" Accurate badysis of ancient pigments has confirmed that tiny cyanobacteria dominated the base of the food chain in the oceans a billion d & # 39; years. why animals did not exist at the time, "Gueneli said.

<p>  The emergence of large, active organisms was likely to have been contained by a limited supply of larger food particles, such as algae, principal investigator Jochen Brocks, an badociate professor at the University of Toronto. ; ANU.

<p>" The algae, though still microscopic, are a thousand times larger than cyanobacteria and are a very good source of food. richer.

<p>  "The cyanobacterial oceans began to disappear about 650 million years ago, when algae began to spread rapidly to provide the energy necessary for the evolution of complex ecosystems, where big animals, including humans, could thrive. " I said.
