You read it right.
There has been the World’s Oldest Colour discovered.
And the ‘literally’ world’s oldest colour, which is also the oldest biological colour discovered, is found in the rocks beneath the Sahara Desert.
Is’nt this too interesting a thing to read about..??
It obviously is…!!
So, I shall today give a brief detail about the discovery of the world’s oldest colour.
This discovery of the oldest colour is also going to be the oldest geological record. The scientists from Australian National University led out an International research conducted with the scientists from Japan and US. This discovery made the researchers conclude, bright pink to be the oldest biological colour discovered yet.
An oil company in the Taoudeni basin had been drilling holes deep inside the ground while looking for oil. That was when they hit a deep, black, oil shale. The rocks were then sent to ANU. After a deep analysis, the rock turned out to be 1.1billion years old.
The pigments discovered and extracted after crushing the 1.1 billion-year-old rocks found in the marine shale deposit drew the researchers’ attention towards the origin of life on earth. These rocks found beneath the Sahara desert, in the Taoudeni basin, Mauritania, West Africa not just helped the scientists discover the oldest colour but, could also help in the explanation as to why it took an extremely long duration of 4 billion years for the formation of animal life on earth.
These pigments found in the Sahara desert are found to be 500 million years older than the ones that were the oldest before the aforesaid. The reports of the research record the following details:
* molecular fossils were found to be green in colour.
* colours ranging from blood red to deep purple were also found but, majorly in the concentrated form.
* when diluted, the resultant was the colour pink, i.e., bright pink.
* the pigments were 1.1 billion years old.
The molecules were extracted after crushing the rocks to powdery form along with the organic solvents. The oil extracted in the end was found to be pink in colour. Thus, the bright pink, for now, is declared to be the oldest biological colour discovered.
The discovery was made by, Nur Gueneli, a PhD student. In her statement, she said, “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.”
Despite the official conclusion of the discovery of the World’s oldest colour, there are a few questions which need explanation. Some of these are:
# how can this research conclude bright pink to be the oldest colour in the world?
Answer: Be it anything…Everything has its own distinct colour. And this possession of colour has the straight connection towards the origin of the thing that we consider for example. The researchers found the pigments of the rocks mentioned afore has the oldest physical colour and is also the oldest biological pigment.
The molecules of these pigments had possessed a colour billion of years ago and they still do have that colour.
Jochen Brocks, an earth scientist at ANU, to explain this point said, “Imagine you would find fossilized dinosaur skin that after 100 million years was still iridescent green or blue,”# The reports say, that this discovery store the origin of animal life on earth in a completely new direction. But, how does this discovery affect the evolution?
Answer: initially it was believed that the formation of larger animals with complex body mechanism had something to do with the lack of oxygen on the planet. The Associate Professor Brocks from ANU said, “The pigments that we found tell us a different story — they tell us that we are probably lacking food, these pink pigments, their exact structure, and composition tells us there was an efficient energy food source missing at the base of the food web,” So, the shortage of food required could be a reason behind as to why it took so long for the animal formation on earth.
