Whether it is polar bears, primates or parkland, the belief that all living things deserve equality of rights is heating up. In fact, a group of scientists now believe dolphins should have the same rights as humans based on their intelligence. Lori Marino, a zoologist at Emory University in Atlanta, made international headlines for her recent work on dolphin intelligence. Using MRI scans, Marino compared the brains of dolphins to primates revealing that dolphins are the second most intelligent creatures on earth after the human.
