Scientists discover the world's oldest biological color

The video discusses the discovery of bright pink pigment in marine black shales beneath the Sahara Desert, identified as molecular fossils of chlorophyll from ancient photosynthetic organisms. These organisms, primarily cyanobacteria, thrived in ancient oceans a billion years ago. Around 650 million years ago, these oceans began to disappear, and algae started to spread, significantly contributing to the evolution of ecosystems.
