New research shows that bioluminescence—a phenomenon in which organisms generate visible light through a chemical reaction—has evolved many more times among marine fishes, and likely throughout the entire tree of life, than previously thought. In a study published in the journal PLOS ONE today, scientists from the American Museum of Natural History, St. Cloud State University, and the University of Kansas reveal that bioluminescence evolved 27 times in marine ray-finned fishes alone.
==============================================
Bioluminescence evolved independently in Nature over 40 times, a sign that being able to emit light is useful in the processes of fitness & evolution.
