(Phys.org)—For nearly 260 years—since Carl Linnaeus developed his system of naming plants and animals—researchers classified species based on visual attributes like color, shape and size. In the past few decades, researchers found that sequencing DNA can more accurately identify species. A group of single-celled algae—Symbiodinum—that live inside corals and are critical to their survival—are only now being separated into species using DNA analysis, according to biologists.
