When a new species is discovered, it's tempting to imagine an adventure novel, said Chan Kin Onn of Michigan State University. "Most people have this image of an intrepid explorer braving an isolated mountain or some other remote place, and stumbling across a creature that no one has ever seen before," Chan said. Sure, that still happens occasionally. "But most of the time it's far less glamorous," he added.
