Eve Spoke: Human Language and Human Evolution
Eve Spoke: Human Language and Human Evolution
If we were to summon the first man and woman from their prehistoric graves, what would they--indeed, what could they--say to us? The human imagination never ceases to be captivated by the quest for its own roots. Who were our ancestors? In the evolutionary clash of brains and brawn, what was it that prevailed and made us, Homo sapiens, uniquely human? Today scientists cite language as the distinctively human feature. But what is language--a sign, a grunt? a sound with collective symbolic meaning? This remarkable book seeks to set the record straight with a critical refinement of the language theory, providing us for the first time with a scientific explanation of how Eve came to speak at all. Wrestling with the age-old question of why such a large gulf exists between humans and other animals, Philip Lieberman mines both the fossil record and modern neuroscientific techniques to chart the development of the anatomy and brain mechanisms necessary for human language as we know it. Eschewing any notion of a language gene or instinct, he pursues instead an evolutionary path in which environment acts on a biological capacity to reveal the interconnectedness of systems that make us most human: precise motor skills, speech, language, and complex thought. Eve Spoke challenges the dominant scientific theories of language's origins and forges a new understanding of the role of language in our evolution. Lieberman interweaves his decades of research in anthropology, neuroscience, psychology, and linguistics with fascinating studies and playful discoveries on such disparate matters as the demise of the Neanderthals, the limits of chimp language, the chinchilla's share of the language gene, and Mt. Everest's contribution to language research.Speaking, like breathing, is something we do every day without thinking. And just like breathing, speech is the result of a complicated dance between neural mechanisms and muscle responses. Although everybody makes use of language--in some form or another--little is actually understood about what it is or how it began. In Eve Spoke, Philip Lieberman, a professor of cognitive science and linguistics, outlines his own theories about this mysterious subject. From development of the human vocal tract to the latest models of where language skills occur in the brain, Lieberman covers the physical aspects of producing speech. He then tries to explain just how the brain puts it all together to create meaning from sound.
