Scientists find the world's oldest color

Scientists have found what they say is the oldest color in the world, namely bright pink. The facts about the history of the pigment were discovered after researchers destroyed 1.1 billion years old rocks in flakes of marine deposits found in the rocky layers of the Sahara Desert, in the Taoudeni basin of Mauritania (western Africa).

"Of course you might say that everything (rocks) has several colors," said Prof. Jochen Brocks, senior researcher leader from the Australian National University. "What we found was the oldest biological color," he continued as quoted by The Guardian on Wednesday, June 11, 2018.

Then, Prof. Brocks compared it to the discovery of a 100 million-year-old T-Rex bone. "It (the T-Rex bone fossil) also has color, but tends to have a gray pigment base, or brown. But that won't tell you what T-Rex's skin is like," Prof Brocks continued.

He explained that the newest pigment molecules found by his team did not come from large creatures, but microscopic organisms that lived in the early era of the formation of the Earth.

The oldest color, was first discovered by a doctoral student named Nur Gueneli, who destroyed fossil rocks into powder. Then, she extracts and analyzes the molecules of ancient organisms from the chemicals they contain.

Gueneli said the pigment was half a billion years older than the discovery of the previous fossil pigment. "Bright pink pigments are molecular fossils of chlorophyll produced by ancient photosynthetic organisms, which inhabit ancient oceans," she said in a statement. *** [EKA | FROM VARIOUS SOURCES | THE GUARDIAN]
