New research shows that the second most diverse group of hard corals first evolved in the deep sea, and not in shallow waters. Stylasterids, or lace corals, diversified in deep waters before launching at least three successful invasions of shallow water habitats in the past 30 million years. This finding contradicts a long-established theory that suggests corals and other marine animals all evolved in shallow water before migrating into deeper habitats.
