Chasing Doctor Dolittle: Learning the Language of Animals is a book that shows that a number of animals have either language or something close to language. We humans no longer can make the claim that we are the only ones with language, that language is a unique human trait.
In the book, I present my Discourse System theory, that suggests that language is like many organ systems, like the skeletal and circulatory systems, for example, and the system consists of all of the physiological and anatomical structures necessary for the reception, interpretation, and production of the signals that we think of as language.
On this page, I posted pictures of animals that I talk about in Chasing Doctor Dolittle, along with the page numbers in the book where I talk about them.
Because the book does not have any pictures, I want my readers to experience visually the magic and beauty of the animals that I discuss in the book.
