By Justin Gregg

How clever are dolphins? Is their conversation approach rather as advanced as human language? And are they as pleasant and peaceable as they're made out to be?

Justin Gregg weighs up the claims made approximately dolphin intelligence and separates clinical truth from fiction. He provides the result of the newest study in animal behaviour, and places our wisdom approximately them into viewpoint with comparisons to medical stories of alternative animals, particularly the crow family members and nice apes. He supplies interesting money owed of the demanding situations of trying out what an animal with flippers and no facial expressions may possibly really be pondering. Gregg's evidence-based process creates a accomplished and up to date research of this interesting animal as a way to attract all these intrigued through dolphin behaviour.

Example text

Not by suggesting that dolphins are stupid, mind you, but by being honest about what the science is, or is not, telling us about dolphin intelligence. Let’s begin by tackling the organ that gives rise to it: the brain. 2 He argued that it is large brain size that leads to the ability to produce and comprehend language, culture, or any of the other intellectual feats made famous by Homo sapiens. By his reckoning, only elephants and a handful of cetacean species had brains large enough to harbor an intelligence that could rival that of humankind (chimpanzees were scratched off his list due to their small brain size).

For humans and other mammals, the cortex, and in particular 31 A R E DOL PHINS R E A L LY SM A RT? the neo-cortex, is the part of the brain most deeply associated with memory, reasoning, creativity, decision making, sense of self, language (in humans), emotion, abstract thinking, etc. In the book Smarter than Man? ”42 In reality, while the dolphin cerebral cortex has a larger surface area than the human brain (3,745 cm2 vs. 44 Regardless of its relation to the size of the human cortex, the dolphin cortex is undeniably large for a nonprimate, or any animal for that matter.

Agency and imitation Moving up from body-awareness we find the concept of agency, which in its most basic form is the sense that one can control one’s movements. There is debate in the literature as to how proprioception, sensory information, and motor movement and feedback combine to create both a sense of agency and of awareness of body, and whether or not agency and body-awareness might be mediated by separate pathways in the brain.
