A Brief History of the Mind: From Apes to Intellect and Beyond

by William H. Calvin

Book Overview

This book looks back at the simpler versions of mental life in apes, Neanderthals, and our ancestors, back before our burst of creativity started 50,000 years ago. When you can't think about the future in much detail, you are trapped in a here-and-now existence with no "What if" and "Why me?" William H. Calvin takes stock of what we have now and then explains why we are nearing a crossroads, where mind shifts gears again.

Savannah spear chucker to Shakespeare

Always a lively and informative read, Calvin has capped his many fine works on the human intellect with this book. Never hesitant to propose novel ideas, he incorporates fresh thinking on the cause of our consciousness. "Stories around the campfire" depicts his theme - the campfire for cooking meat and the narratives exchanged among the diners. The meat implies hunting and the conversation implies speech and complex thinking. Only humans engage in these practices - how did that come to be? In this provocative and compelling book, Calvin answers this and other questions with his usual expressive style. Abetted by explanatory diagrams and photographs, he takes us back to a distant time in searching for our origins. We learn what makes us unique among primates and are given a view of possible future paths. No work in anthropology can ignore our primate relatives. Calvin's opening chapter asks "what is it like to be a chimpazee?" This query raises the point of similarities and differences among primate species. Apes have fair-sized brains and useful "hands". While some hunt, some use tools and all vocalise, only humans developed those capacities fully to create complex societies and learn to write books - or plays and poetry. All fossil evidence, plus genetics, Calvin reminds us, indicate our origins lay close to what chimpanzees exhibit today. How did we change from a forest-dwelling ape to one living in nearly every habitat and babbling expressively? For Calvin, environment shifts are a major driving force in evolution - perhaps none more so than in the case of human evolution. Variations in climate drives adaptation, and our ape-like ancestors were challenged by some severe, and possibly abrupt, shifts. More than simply more or less frequent rainfall, these changes modified whole habitats. Our ancestors had to relocate, shift lifestyles or both. Calvin argues that the shift meant a new existence, a new diet plus gaining some additional skills. The new diet was meat. With the human brain consuming 20 per cent of the body's resources just to "tick over", a high protein source is a necessity. Primates are mostly vegetarian, with chimps adding some termites and the occasional monkey for dinner. Shrinking rainforests reduced available fruits and nuts, leaving meat as a more significant diet item for the new ape. There are two ways of obtaining meat - scavenging it or hunting it. Scavenging means waiting for leftovers or chasing away predators. Either is risky. Active hunting is more direct, but requires complex skill sets involving vision, muscle coordination, memory capacity and predictive skills. The act of spear-throwing, which Calvin calls a "structured suite" had to be a "package deal" of muscle functions directed by a developing cortex. To Calvin, the "package deal" implies a sudden rise in evidence for complex human cognition. With bipedalism a foundation, the new ape could build thinking capacity with tool-makin

NOT READY FOR PRIME TIME

For a short book, (fewer than 200 pages), Dr. Calvin provides a wealth of information from a wide variety of scientific disciplines, and a HUGE bibliography. He approaches evolutionary cognitive development from the standpoint of a neurobiologist. He has excellent, entertaining quotes to begin and finish many chapters, and nice illustrations. He provides brief (one paragraph) chapter summaries in the Table of Contents. I read that first, and reread individual chapter summaries before and after each chapter. In chapter 8, he discussed this structured, obsessive, pattern-seeking behavior of mine. Here is the plot: 7 million yrs ago, we emerged from the apes. Bt 160,000 yrs ago, we were homo sapien. By 50,000 yrs ago, we were homo sapien sapien - same physique, same sized brain, just soft-wired more elegantly. Dr. Calvin says, "It's just in the last 1% of that up-from-the-apes period that human creativity & technological capabilities have really blossomed. It's been called 'The Mind's Big Bang'." How did this happen? On page 153, he listed 5 candidates, all of which he said were probably operative, but he has a favorite. (Interestingly, he leaves out Matt Ridley's favorite from THE RED QUEEN; that it's all about the battle between the sexes.) In Dr. Calvin's theory, "Evo-Devo," he relies on syntax development and spear-throwing skills as catalysts to the "Mind's Big Bang," and spends a lot of of time explaining his thoughts. He is obviously very well informed about language development. I won't try to explain this complex theory here, but I did think it had merit. I thought, however, that for the crown jewel of his book, it was not presented clearly enough. I began to wonder where gene change was going to fit in. As I read, I searched for indications that the current brand of natural selection was in play. In one segment, he suggested what sounded exactly like vertical transmission of memes, although he didn't call them memes. He extrapolated this into the future, saying, "a number of present day human abilities have some potential for future elaboration even without natural selection." I couldn't help but wonder what Richard Dawkins would think about this. It sounded awfully Lamarckian to me. As the plot unfolded, the existing product (our minds) was shown to be jury-rigged and unfinished, in evolution's usual fashion...so, as humans, we have tendencies to misinterpret in our own favor, rationalize, use faulty logic, wage war, etc. In short, we are "NOT READY FOR PRIME TIME." This book is well-written, extensively researched, and entertaining, about a subject in which informed speculation appears to be the state of the art. Too bad we don't have hard evidence for the "how" of evolutionary cognitive function such as what mitochondrial DNA is to geneology. I recommend this book highly, and am inspired to read more on the subject, probably from books he mentions. Because his chart

The rise of "beyond the apes" intelligence

The central event in this book is the human mind's so-called "big bang" which occurred some 90,000 to 50,000 years ago. (These are neurobiologist William Calvin's numbers from page 111 where he notes that "it now appears that humans were behaviorally modern before the last great Out of Africa" which is now understood as taking place between 60,000 and 40,000 years ago, as determined by the latest tweaking of the mitochondrial DNA dating data.) Professor Calvin leads up to this event by starting with the proto ape that was our ancestor (and the ancestor of modern apes) that lived some seven million years ago. He takes us from that ape's jungle habitat to the woodlands, where our ancestors learned to walk upright, to the savannahs where they ran down, killed and ate large game animals. Somewhere along the way we got smart. But, Calvin wonders, did we get smart enough? He sees a disconnect between our abilities and the world we have inherited. He asks: "Where does mind go from here, its powers extended by science-enhanced education and new tools--but with its slowly evolving gut instincts still firmly anchored to the ice ages?" Are we just a "rough-around-the-edges prototype, the preliminary version that evolution never got a chance to further improve before the worldwide distribution occurred?" (p. 178) In other words, are we using Stone Age instincts to cope with Information Age problems? It is interesting to note that in psychologist Keith Stanovich's recent book The Robot's Rebellion: Finding Meaning in the Age of Darwin (2004) he is concerned with the same problem from an entirely different point of view. He writes about the "potential mismatches between the cognitive requirements of the Environment of Evolutionary Adaptation and those of the modern world." Of course the problem, as both writers point out, is that cultural evolution out-sprints the biological so that our genotypes are still in the woodlands and on the savannahs as the ice ages come and go while our phenotypes have to deal with traffic jams, weapons of mass destruction, and the paperwork for our HMOs. One of Calvin's more intriguing ideas comes from his dictum that "behavior invents and...New form follows new function." (p. 159) He argues that the higher intellectual functions of humans came from the development of a "structured suite" of brain machinery that "is shared in part with some nonintellectual functions." (p. 94) He sees "accurate throwing" as part of this structured suite, and argues that learning to hit a moving target (say a small animal), because it involved several parts of the body (hand, wrist, arm, shoulder--and eyes and legs for that matter) in close coordination, several parts of the brain were used simultaneously as well. Consequently a "structured suite" developed in the brain that later was used for the development of symbolic language. What he is saying is that, the syntax of language--that is, the "something" does "something" to "someth

Thought provoking yet personable

This is a thought provoking yet personable survey of the evolution of our species' mental abilities. I read it after I'd written my book, "Concept: A ProtoTheist Quest for Science-Minded Skeptics", else I might have used some of his ideas in my chapters eight and nine (I do reference two of his earlier books). He elaborates and illustrates many of the concepts (tho' sometimes he uses `concept' were I'd use `percept'). However he largely ignores the functions of the pre-, sub- and un-conscious, yet speculates on "The Future of the Augmented Mind." Also, while he mentions on pages 171-2 "the evolutionary trajectory we've been on," he doesn't elaborate (as I do in chapter eleven) and thus has difficulty sustaining his optimism about our future.

The Story of the Mind?s Big Bang

"A Brief History of the Mind" is a breezy, readable account of the evolution of modern humans from ancient African primates, starting around 7 million years ago. There have been some interesting new insights in the field during the past few years, and the story is well worth retelling. Indeed, what makes humans so different from other animals is that we would consider telling "our story" at all.The core of the book is the chain of events that could have created our modern minds from those of our ancestor apes. It stresses the concept of humans getting an evolutionary "free ride" from fortuitous changes. For example, the author offers the controversial suggestion that the increased cortical connections that eventually enabled our higher thinking abilities originally benefited pre-humans by helping them coordinate the complicated body movements used in hunting herd animals. Those with more neural connections had a better chance of bringing home lunch. Intelligent thought was simply a happy later by-product.Anthropologists usually look backwards, but this History takes a quick peek at the future. Modern minds are far more than the hardware of cortex and neurons. Human infants start busily "softwiring" language and other skills into their brains as soon as they are born. William Calvin considers this new stage of evolution - one that we actually have some control over - and comes up with some surprising, and disturbing, predictions for our postmodern future.
