Dolphins Do Argue

I came into this world a devout advocate of a "balanced and healthful ecology." I grew up believing that every creature on earth has the capacity to perceive, communicate, and evaluate its fellow creatures.



Some say dolphins may be the closest mammals to humankind. Others say dolphins are considered to be the most intelligent mammal on earth.



Does it mean that dolphins are capable of argumention and debate? This sounds unbelievable, but I believe it's true. In what way, that I still have to discover yet.
