Publisher Description
How intelligent are dolphins? Is their communication system really as complex as human language? And are they as friendly and peaceful as they are made out to be?
The Western world has had an enduring love affair with dolphins since the early 1960s, with fanciful claims of their 'healing powers' and 'super intelligence'. Myths and pseudoscience abound on the subject. Justin Gregg weighs up the claims made about dolphin intelligence and separates scientific fact from fiction. He puts our knowledge about dolphin behaviour and intelligence into perspective, with comparisons to scientific studies of other animals, especially the crow family and great apes. He gives fascinating accounts of the challenges of testing what an animal with flippers and no facial expressions might be animal behaviour, Gregg challenges many of the widespread beliefs about dolphins, while also inspiring the reader with the remarkable abilities common to many of the less glamorized animals around us - such as chickens.
PUBLISHERS WEEKLY
Gregg, described as a "spokesperson for mainstream science," and co-editor of Aquatic Mammals, analyzes the state of scientific research on dolphin cognition alongside other notable species such as apes, corvids, and bees to address the mystique arising from John Lilly's writings about dolphin intelligence, which inspired some organizations to push for legal cetacean personhood. Gregg argues that defining an animal's intelligence as a single metric is an unscientific attempt to fit behaviors into a human-like model. He prefers operational definitions of specific cognitive tasks, which allow us to acknowledge limited skills, such as facial recognition abilities among sheep. Gregg dismisses brain size or the possession of specific biological structures as indicators of complex cognition, and highlights difficulties in test design for understanding a theory of mind, including the mirror self-recognition test. Defining language in terms of parameters like limitless expression and arbitrariness of symbols, Gregg shows that, like chimpanzees, dolphins have communication systems with some sophisticated characteristics, but which do not approach the complexity of human language. Finally, Gregg addresses the myth of dolphins as gentle creatures, highlighting aggressive behaviors and infanticide in the wild, leaving readers with a sense of dolphins as fascinating creatures, but not ones to put on a pedestal for wisdom, ethics, or nearness to the human experience.
