Study traces bioluminescence back 540 million years in octocorals
Bioluminescence, the ability of organisms to emit light, originated in marine invertebrates known as octocorals at least 540 million years ago, a study by Smithsonian scientists indicates. This discovery extends the known timeline of bioluminescence's development in animals by about 300 million years. Published in the Proceedings of the Royal Society B on April 23, the study provides new i
