The book examines the originsof language and grammar and also looks at the nature of being human. As a species, we have a long history of trying to find aspects of ourselves that are exclusively human.Some of the features of humanity thought to be solely the realm of the spiritual - for example cognition andemotion -are increasingly being explained in terms of physical effects.Exclusive physical functions are now questioned too - bipedality, dexterity, socialisation, delayed gratification. Couldthe differences between the human and animal kingdombe a matter of degrees rather than absolutes? Language, and language grammar,is one territory that might provide an answer. Martin Edwardes builds a story examining the evolutionary sources of our self-recognition, of human culture and social institutions andof the cognitive forms that lie behind our linguistic grammatical forms.He covers the current thinking in the field of language origins and goes on todevelop an essentialnewtheory of the origins of grammar.
