Hurford of the University of Edinburgh and Professor Frederick J. Newmeyer of the University of Washington. Preface My fascination with language origins goes back at least to the 1980s when some students and faculty members from the Department of Anthropology at the University of Michigan used to get together periodically for very informal evening seminars on topics of human evolution. More than once, archeologists turned to me, the only linguist in the group, and asked ‘‘When did language begin?’’ I could do nothing except look blank and say ‘‘I dunno,’’ but the question prodded me into thinking about how it all might have started. This book is the result of that thinking. Over the years, many friends, colleagues, and correspondents oVered their wise counsel as I worked on various articles on the subject (some of which form the basis of sections in the book and are listed in the Acknowledgements below) and I must again give my thanks to A. L. Becker, Derek Bickerton, Paul Bloom, Loring Brace, William Croft, Iain Davidson, Penelope Eckert, Mark V. Flinn, Allan Gibbard, Virginia Guilford, Barbara King, Chris Knight, Frank Livingstone, Bruce Mann- heim, John Mitani, Thomas Moylan, Emanuel Polioudakis, Ernst Pulgram, Roy Rappaport, Robert Seyfarth, Michael Tomasello, Vir- ginia Vitzthum, Ron Wallace, and Richard Wrangham. Some of these same people, and many others as well, have helped in one way or another with the book itself. I will never overcome my astonishment at the generosity of scholars, several of whom I know only through e-mail, who have responded to my pleas for help. Simon Kirby and Jim Hurford have on several occasions done their best to help me understand work on the computer simulation of language evolution. Judy Kegl not only answered my questions and sent me papers, but sent me a stunning tape about young Nicaraguan signers. Another stunning tape, this one about bonobos, was sent by Sue Savage-Rumbaugh. Adam Kendon helped me to understand the diVer- ences between various kinds of gestures. William Irons brought me up to date on the relation between status and reproductive success, and Judith Irvine did the same for the relation between status and valued vii Preface forms of language. Ruth Lesser educated me about aphasia. Karin Schmidt helped me with the relationship between human and animal gestures. Simon Frasier did his best to untangle my confusion about the FOXP2 gene. Bruce Richman guided my reading on music. Judith Becker instructed me about the rhythm and metrics of both music and language. Paula Berwanger guided my reading on sign language. Over the years, Barbara King has cheerfully responded to numerous queries on matters primatological. Iain Davidson has sent me countless e-mail messages, hoping to straighten out my notions of prehistory and much else. For two decades, Milford WolpoV has never stopped arguing with me, always hoping to educate me. Among many other acts of gener- osity, he supplied the data from which Illustration 7 was constructed. Anne Hvenekilde was able to read early drafts of two chapters and, as always, she made sharp criticism even while encouraging me to continue. Allan Gibbard and Robert Whallon read and oVered helpful comments about parts of the manuscript at later stages. Three good friends read the whole thing. Thomas Trautmann was the Wrst of these and, along with numerous astute criticisms and suggestions, he gave me the conWdence to continue. Sheila Procter and Derek Brereton read later drafts and both helped me in all sorts of ways toward both good sense and clarity. Recruited by OUP, Frederick Newmeyer reviewed the penultimate draft. He not only saved me from several embarrassing errors but pushed me to clear up some of my more murky prose. These thoughtful friends did their best to set me straight. Where I have failed to learn from them, blame me. Robbins Burling Ann Arbor, Michigan March 2005 viii Acknowledgements Several of the chapters in the book grew, in part, from earlier articles. I Wrst suggested that we should pay more attention to comprehension in an article called ‘‘Comprehension, Production and Conventionali- zation in the Origins of Language’’ in The Evolutionary Emergence of Language, edited by Chris Knight, Michael Studdert-Kennedy, and James R. Hurford and published by Cambridge University Press in 2000. This is reXected most closely in Chapter 1, but this entire book is, in a sense, an expansion of that article. Parts of Chapters 2 and 3 appeared in a rather diVerent form in ‘‘Primate Calls, Human Lan- guage, and Nonverbal Communication’’ in 1993 in volume 14 of Cur- rent Anthropology, pages 25–37, and published by The Wenner-Gren Foundation for Anthropological Research. A Wrst attempt to organize the ideas in Chapter 4 appeared in 1999 in volume 10, section 32 of the electronic journal Psycoloquy as ‘‘The cognitive prerequisites for lan- guage’’. Parts of Chapters 5 and 6 are adapted from ‘‘Motivation, Arbitrariness, and Conventionality’’ that appeared in 1999 in The Origins of Language: What Nonhuman Primates Can Tell Us, edited by Barbara J. King and published by the School of American Research, Santa Fe. The Wrst half of Chapter 10, is based on ‘‘The selective advantage of complex language,’’ which appeared in 1986 in pages 1–16 of volume 7 of Ethology and Sociobiology, published by Elsevier Science Publishing Co. Inc. ix This page intentionally left blank 1 In the beginning Few topics about which scholars have puzzled can be quite so intri- guing and so tantalizing, but at the same time so frustrating, as the evolution of the human capacity for language. Nothing so decisively sets us apart from our primate cousins as our constant chatter. It is no exaggeration to credit language for the very humanity that distin- guishes us from the beasts from which we sprang. If we are even a tiny bit curious about our own origins, we have to be curious about the origins of language. This is why it so frustrating to have no direct evidence for the lan- guage of our early ancestors. Fading as soon as it is uttered, spoken language leaves no trace. A few of our remote forebears left their bones in places where we could Wnd them, and as more and more of these bones have been moved to museums, we have gained a clearer under- standing of the several million years of evolution during which our bodies diverged from those of chimpanzees. The tools that early humans knocked from stones have survived in their thousands, and they tell us a good deal about early technology. But it was only after writing was invented, a mere Wve or six thousand years ago, that earlier languages could leave any trace. By then, the human capacity for spoken language had already had a very long history. Not even the earliest writing can tell us anything about the far more ancient periods when people Wrst began to talk. The lack of direct evidence for such a crucial part of our heritage has left the topic open to speculation, some of it reasonable, some that might be called ‘‘imaginative,’’ and some downright crazy, and this has 1 In the beginning brought the subject a certain disrepute.
