How accelerating evolution could help corals survive future heatwaves – new study

As global warming accelerates, extreme heatwaves are causing widespread death of tropical reef corals. Most corals rely on tiny algae cells living within their tissues that photosynthesise and produce energy. Corals use this energy to build their skeletons that create the reef structure.
