EARTH — It turns out bright pink is the oldest color in the world.<br /><br />According to a recent study from Australian National University, pink pigment was found in the marine black shales deep beneath the Sahara desert in Africa.<br /><br />The researchers reportedly crushed the rocks into powder then extracted and analysed the molecules of ancient organisms inside those rocks.<br /><br />The bright pink pigment discovered was actually the "molecular fossils" of chlorophyll produced by ancient photosynthetic organisms living in an ancient ocean, which no longer exists.<br /><br />The fossils itself range from "blood red to deep purple" in concentrated form, and turn bright pink when it's diluted.<br /><br />A researcher involved in the study commented saying after analyzing the ancient pigment, confirm tiny cyanobacteria used to live in the ocean a billion years ago.<br /><br />Ancient oceans filled with cyanobacteria started to disappear around 650 million years ago, which is when algae started to spread rapidly which helped the ecosystems to evolve.
