Overview: Most scholarly speculation on the origin of human language has centered around speech. However, the growing understanding of sign languages on human development has transformed the debate on language evolution. David F. Armstrong's new book Show of Hands: A Natural History of Sign Language casts a wide net in history and geography to explain how these visible languages have enriched human culture in general and how their study has expanded...

Language did not evolve only in the distant past. Our shared understanding of the meanings of words is ever-changing, and we make conscious, rational decisions about which words to use and what to mean by them every day. Applying Charles Darwin's theory of "unconscious artificial selection" to the evolution of linguistic conventions, Daniel Cloud suggests a new, evolutionary explanation for the rich, complex, and continually reinvented meanings

There are approximately six thousand languages on Earth today, each a descendant of the tongue first spoken by Homo sapiens some 150,000 years ago.While laying out how languages mix and mutate over time, linguistics professor John McWhorter reminds us of the variety within the species that speaks them, and argues that, contrary to popular perception, language is not immutable and hidebound, but a living, dynamic entity that adapts itself to an ever-changing...

Drawing on "living linguistic fossils" such as "ape talk," the "two-word" stage of small children, and pidgin languages, and on recent discoveries in paleoanthropology, Bickerton shows how a primitive "protolanguage" could have offered Homo erectus a novel ecological niche. He goes on to demonstrate how this protolanguage could have developed into the languages we speak today. --From publisher's description.

A pioneering linguist upends widely held beliefs about the acquisition and use of language by debunking theories on a wide range of disciplines and through citing examples from his four decades of field work with Amazonian hunter-gatherers. -- "Mankind has a distinct advantage over other terrestrial species: we talk to one another. But how did we acquire the most advanced form of communication on Earth? Daniel L. Everett, a "bombshell" linguist and...

The Recursive Mind challenges the commonly held notion that language is what makes us uniquely human. In this compelling book, Michael Corballis argues that what distinguishes us in the animal kingdom is our capacity for recursion: the ability to embed our thoughts within other thoughts. "I think, therefore I am," is an example of recursive thought, because the thinker has inserted himself into his thought. Recursion enables us to conceive of our...
