Coral reefs provide shelter, sustenance and stability to a range of organisms, but these vital ecosystems would not exist if not for the skeletal structure created by stony corals.
Coral reefs provide shelter, sustenance and stability to a range of organisms, but these vital ecosystems would not exist if not for the skeletal structure created by stony corals. Now, KAUST scientists together with an international team have revealed the underlying genetic story of how corals evolved from soft-bodied organisms to build the myriad calcified structures we see today.
“While the processes involved in coral calcification are well understood, it is less clear how corals’ ability to grow calcium carbonate skeletons actually evolved,” says Xin Wang, a former KAUST Ph.D. student who worked on the project under the supervision of Manual Aranda.
“How did a squishy anemone-like organism begin to build reefs?” asks Aranda. “Did the ‘tools’ already exist in their genetic code?”
