Originally published in 1976, this title deals with the problem of how we tell left from right. The authors argue that the ability to tell left from right depends ultimately on a bodily asymmetry, such as preference for one or the other hand, or dominance of one side of the brain. This has implications for child development, reading disability, navigation, art, and culture.

Evolutionary science has long viewed language as, basically, a fortunate accident a crossing of wires that happened to be extraordinarily useful, setting humans apart from other animals and onto a trajectory that would see their brains (and the products of those brains) become increasingly complex. But as Michael C. Corballis shows in The Truth about Language, it's time to reconsider those assumptions. Language, he argues, is not the product of some "big bang" 60,000 years ago, but rather the result of a typically slow process of evolution with roots in elements of grammatical language found much farther back in our evolutionary history. Language, Corballis explains, evolved as a way to share thoughts and, crucially for human development, to connect our own "mental time travel," our imagining of events and people that are not right in front of us, to that of other people. We share that ability with other animals, but it was the development of language that made it powerful: it led to our ability to imagine other perspectives, to imagine ourselves in the minds of others, a development that, by easing social interaction, proved to be an extraordinary evolutionary advantage. Even as his thesis challenges such giants as Chomsky and Stephen Jay Gould, Corballis writes accessibly and wittily, filling his account with unforgettable anecdotes and fascinating historical examples. The result is a book that's perfect both for deep engagement and as brilliant fodder for that lightest of all forms of language, cocktail party chatter.

"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 own minds and the minds of others. It also gives us the power of mental "time travel"--the ability to insert past experiences, or imagined future ones, into present consciousness.

Drawing on neuroscience, psychology, animal behavior, anthropology, and archaeology, Corballis demonstrates how these recursive structures led to the emergence of language and speech, which ultimately enabled us to share our thoughts, plan with others, and reshape our environment to better reflect our creative imaginations. He shows how the recursive mind was critical to survival in the harsh conditions of the Pleistocene epoch, and how it evolved to foster social cohesion. He traces how language itself adapted to recursive thinking, first through manual gestures, then later, with the emergence of "Homo sapiens," vocally. Toolmaking and manufacture arose, and the application of recursive principles to these activities in turn led to the complexities of human civilization, the extinction of fellow large-brained hominins like the Neandertals, and our species' supremacy over the physical world.

It is often said that speech is what distinguishes us from other animals. But are we all talk? What if language was bequeathed to us not by word of mouth, but as a hand-me-down?

The notion that language evolved not from animal cries but from manual and facial gestures--that, for most of human history, actions have spoken louder than words--has been around since Condillac. But never before has anyone developed a full-fledged theory of how, why, and with what effects language evolved from a gestural system to the spoken word. Marshaling far-flung evidence from anthropology, animal behavior, neurology, molecular biology, anatomy, linguistics, and evolutionary psychology, Michael Corballis makes the case that language developed, with the emergence of Homo sapiens, from primate gestures to a true signed language, complete with grammar and syntax and at best punctuated with grunts and other vocalizations. While vocal utterance played an increasingly important complementary role, autonomous speech did not appear until about 50,000 years ago--much later than generally believed.

Bringing in significant new evidence to bolster what has been a minority view, Corballis goes beyond earlier supporters of a gestural theory by suggesting why speech eventually (but not completely ) supplanted gesture. He then uses this milestone to account for the artistic explosion and demographic triumph of the particular group of Homo sapiens from whom we are descended. And he asserts that speech, like written language, was a cultural invention and not a biological fait accompli.

Writing with wit and eloquence, Corballis makes nimble reference to literature, mythology, natural history, sports, and contemporary politics as he explains in fascinating detail what we now know about such varied subjects as early hominid evolution, modern signed languages, and the causes of left-handedness. "From Hand to Mouth" will have scholars and laymen alike talking--and sometimes gesturing--for years to come.

If we've done our job well and, let's be honest, if we're lucky you'll read to the end of this description. Most likely, however, you won't. Somewhere in the middle of the next paragraph, your mind will wander off. Minds wander. That's just how it is. That may be bad news for me, but is it bad news for people in general? Does the fact that as much as fifty percent of our waking hours find us failing to focus on the task at hand represent a problem? Michael Corballis doesn't think so, and with The Wandering Mind, he shows us why, rehabilitating woolgathering and revealing its incredibly useful effects. Drawing on the latest research from cognitive science and evolutionary biology, Corballis shows us how mind-wandering not only frees us from moment-to-moment drudgery, but also from the limitations of our immediate selves. Mind-wandering strengthens our imagination, fueling the flights of invention, storytelling, and empathy that underlie our shared humanity; furthermore, he explains, our tendency to wander back and forth through the timeline of our lives is fundamental to our very sense of ourselves as coherent, continuing personalities. Full of unusual examples and surprising discoveries, The Wandering Mind mounts a vigorous defense of inattention even as it never fails to hold the reader's.

What is it that allows human beings to think the way we do? What enables us to communicate with one another through the use of speech? Is the difference between Homo sapiens and other apes simply a matter of degree or are we unique and discontinuous from other species? Michael C. Corballis argues that this century-old debate lies in the fact that humans are the only primates that are predominantly right-handed, a sign of the specialization of the left hemisphere of the brain for language.

Surveying the current views of evolution using evidence from archaeology, linguistics, neurology, and genetics, Corballis takes us on a fascinating tour of the origins and implications of the structure of the human brain, accounting for the dominance of humanity over all species.
