CANBERRA – Scientists have found what they say is the oldest biological color in the world. The color comes from ancient rocks under the Sahara Desert.
The pigment of 1.1 billion years ago has a bright pink color, but their concentrations range from blood red to purple.
Australian scientists say the pigment derived from fossil chlorophyll molecules produced by marine organisms. The researchers crushed shale rock powder to extract the pigment.
"Imagine that you can find dinosaur skin fossils of original color, green or blue … that's the kind of invention we do," says Professor Jochen Brocks. ANU) was cited from BBC Tuesday (10/7/2018).
"It's the real molecule, the oldest colored molecule in the world, when they are held in the sunlight, they become fluorescent pink," he says.
A doctoral student, Dr. Nur Gueneli, found the pigment after using an organic stone powder remover. Brocks says that the extraction process is similar to a coffee machine.
"I heard him screaming in the lab when they were out and running to my office," said Professor Brocks' badistant. It is amazing that it is amazing with the long lasting biological color. "
A mining company has found rocks in the Taoudeni Basin marine shale deposits in Mauritania, West Africa over the last 10 years.," He said.
L & # 39; Pigment badysis revealed that they had produced cyanobacteria in the ocean.According to Professor Brocks, these discoveries contributed to the understanding of the evolution of life forms on Earth
" Cyanobacteria dominated the base of the food chain a billion years ago, which is why animals are not. "" Life is only a whopping 600 million years that will only be probably not enough food sources, "he added.
This study, which involves American and Japanese scientists, was published in the Proceedings of the National Academy of Science, United States.
