Unlike red algae, whose blooms can damage the ecosystem, green algae form the basis of the food chain, providing food for crustaceans and larger organisms.

Scientists believe the 25 percent loss in genetic material resulted from adaptation by the red algae's ancestor to an extreme environment such as a hot spring or low-nutrient habitat.
