Phys.org / Algae may have launched coral reefs by hijacking coral cells, genetic experiments suggest

The reefs scattered throughout the tropics arose only after algae took up full-time residence in coral cells, supplying corals with abundant food and enabling them to build extensive shallow-water communities. But with warming ...
