International research led by the Australian National University has resulted in the discovery of the world’s oldest biological colour – and it’s pink.
The 1.1-billion-year-old colour dates back to a time before plants, animals or humans appeared on our planet.
German-born Professor Jochen Brocks, an earth scientist at ANU, tells Wolfgang Mueller that the colour was extracted from rocks that were discovered buried deep beneath the Sahara Desert in Africa.
