Dolphins Call One Another By Name?
For centuries, people believed we were the only ones who call each other by unique names, but a new study shows we might not be that special. "Good Morning America" reports scientists say dolphins may be able to call each other by name too. The clicks they make are made in the same way people greet their friends, according to scientists at St. Andrew's University. PNAS.org reports dolphins identify themselves with a "signature whistle" and will mimic their loved ones' whistles when separated.
