Partly because their brains are roughly the same size as humans, and are similarly or superiorly complex (although differently evolved in structure), some marine biologists have speculated that dolphins, and other Cetaceans, are at least as intelligent as humans, and could have several unknown communicative abilities, that surpass human understanding.

Critics say that if dolphins were as smart as us there’d be more evidence of it. But what type of evidence would suffice? The fact that Cetaceans are suffering from (rather than creating) the kind of environmental suicide that humans indulge in, offers little proof of inferiority.

Dolphins have long been observed to take great care and exhibit much intelligence in their day to day lives
