What Makes Them Smart: Dolphins are the Einsteins of the sea. These creature have the capacity for complex thinking and following commands. As extremely social animals, dolphins have been recorded playing, mourning and racing in their pods. The also have a surprisingly intricate language and understanding of tools.
Recent Discovery: Humans just made a breakthrough in deciphering the way dolphins communicate. A speaker has been created that hopefully can replicate the varying frequencies the animal uses to speak. If this invention works, humans could possibly decode the complex language that dolphins have created.
