The Theory of Options: A New Theory of the Evolution of Human Behavior
Sean Gould Manufacturer: Universal Publishers ProductGroup: Book Binding: Paperback ASIN: 1581127006 |
Book Description
Here is an innovative theory of the evolution of human behavior. The theory allows that evolution can account for many behaviors, but points out there are still no viable methods of counseling or therapy based on how humans evolved. And while genes do mold behavior, few human genes are different from those of chimps.The theory also allows that DNA is "selfish", but over the history of life DNA selected in ways that highly conserved genes could express a variety of organisms for little change to themselves. In a similar way, over millions of years neurology evolved towards increasing generalization, where learning neurology could adapt many needs for the same genetic design. These effects, concatenating at an advanced stage of life, restrict the available fitness pathways along which any species can evolve. Human ancestors evolved along a pathway in which fit adaptations were those that maximized the options of behavior, against a cost to evolve. This can account for many complexities of human behavior, such as why humans have morals, or experience religious awe. There is even a theory of psychology, derived from evolution, but viable in its own terms.
This is not just criticism of current evolutionary explanations of human behavior, but a fresh approach to enduring problems, with original mechanisms and insights.

Solid and Insightful.......2002-03-20
Gould's theory of options addresses this problem head on. Current theories try to connect each attribute of intelligence (culture, language, religion, courting habits) to specific environmental factors but that misses the point. Intelligence had to evolve, in its first instance, as a generalized resource. This book offers one of the most original ways to reconcile the many puzzling facts of this topic, that I have seen.

Morality as a solution to navigating life's choices ?.......2002-02-07
Poorly Articulated, Interesting Theory of Human Evolution.......2001-12-11
At the same time, I would be remiss if I did not point out that The Theory of Options is the worst written popular science book that I have ever read. Mr. Gould needs to meet an editor who understands his material. The writing is redundant, repetitious, and poorly grounded in many cases.
The Beak of the Finch is a book that greatly influenced my own perceptions of evolution. Under conditions which can vastly vary from year to year, species of finches in the Galapagos Islands rapidly evolved in terms of their beaks to fit the new feeding conditions over the space of just a few years. This often occurred by the premature death of most of the population that had the least appropriate beak sizes and types for that environment. The genes of the survivors reinforced these changes in beaks, as disciplined by competition for scarce food supplies that favored those with the most appropriate beaks.
Opening this book, I expected a strong argument based on the variability of living conditions that would favor Homo Sapiens developing flexible brains, learning, and decision processes that would speed and ease adaptation without requiring the death of most individuals. Although there was a bit of this approach as it related to migrating into different climate zones (and a too-often repeated example of humans using animals furs rather than their own fur to keep warm, as needed), too little was made of the idea that handling short-term variability in food and climate is critical to establishing a large population on Earth's land.
Instead, the Theory of Options builds from Mr. Gould's observation of the human psychological preference for having more freedom, in the form of choices (or options). The book also makes the point that a large brain that is mostly not hard-wired in stimulus-response ways (like fight or flight instincts) is only worthwhile if being aware of more options provides survival advantages. Now, if a larger, flexible brain provides the ability to find more and better survival solutions, that can be the basis of a new theory of evolution . . . regardless of whether or not Homo Sapiens always prefer to have more choices (something that can be disproven in many situations -- for example, auto dealers who offer fewer choices like Saturn outsell those who offer more like Chevrolet).
My reaction is that what Mr. Gold has articulated is a Theory of Rapid Flexibility, rather than a Theory of Options.
The most interesting parts of the book for me were the discussions of how phylogenies stabilize and become a platform for further evolution in new areas. I had often marveled that Homo Sapiens and chimpanzees have very small genetic differences (1-2%) yet are so different in their capabilities. The more phylogenies that exist, the less it will take for a new genetic difference to create vast advantages in survival performance assuming that the difference fits the environment.
I have often also wondered why we have such large brains, when we apparently use so little of them. From reading this book, I realized that evolutionary changes that work must bring in large, untapped capacity long before it is needed. For example, lions have the speed to catch many of the antelopes in a herd. Yet, they will usually focus on just catching the slowest antelopes. Under harder conditions, lions can chase faster antelopes and survive. More pressed for survival, humans could begin to use more of their brains. Perhaps in the past, more of brains were used as part of the environmental survival challenges faced then. Sexual selection will probably favor this approach, since the attribute will have obvious survival benefits. Until the 20th century, for example, many people thought that the shape of the head determined a great deal about a person's intelligence and character. Those beliefs could have been leftovers of sexual selection preferences that helped create people with larger brains.
One clever device in the book that I liked was the way that the primary schools of thought in these subjects were encapsulated into a brief quote at the beginning of each chapter and section of a chapter. This was a highly condensed way to express a broad perspective of the thought on these subjects, without wasting much of the reader's time and attention.
Mr. Gould suggests in the book that more editions will be coming. I hope he will do so, think about the observations that people have made, improve the arguments and exposition, and encourage people to reread the book in its newest form.

Book Description
The book is aimed at graduate students, researchers, engineers and physicists involved in fluid computations. An up-to-date account is given of the present state of the art of numerical methods employed in computational fluid dynamics. The underlying numerical principles are treated with a fair amount of detail, using elementary methods. Attention is given to the difficulties arising from geometric complexity of the flow domain. Uniform accuracy for singular perturbation problems is studied, pointing the way to accurate computation of flows at high Reynolds number. Unified methods for compressible and incompressible flows are discussed. A treatment of the shallow-water equations is included. A basic introduction is given to efficient iterative solution methods. Many pointers are given to the current literature, facilitating further study.Customer Reviews:

Gilead: A Novel
Marilynne Robinson Manufacturer: Picador ProductGroup: Book Binding: Paperback Similar Items: ASIN: 031242440X Release Date: 2006-01-10 |
Amazon.com
In 1981, Marilynne Robinson wrote Housekeeping, which won the PEN/Hemingway Award and became a modern classic. Since then, she has written two pieces of nonfiction: Mother Country and The Death of Adam. With Gilead, we have, at last, another work of fiction. As with The Great Fire, Shirley Hazzards's return, 22 years after The Transit of Venus, it was worth the long wait. Books such as these take time, and thought, and a certain kind of genius. There are no invidious comparisons to be made. Robinson's books are unalike in every way but one: the same incisive thought and careful prose illuminate both.The narrator, John Ames, is 76, a preacher who has lived almost all of his life in Gilead, Iowa. He is writing a letter to his almost seven-year-old son, the blessing of his second marriage. It is a summing-up, an apologia, a consideration of his life. Robinson takes the story away from being simply the reminiscences of one man and moves it into the realm of a meditation on fathers and children, particularly sons, on faith, and on the imperfectability of man.
The reason for the letter is Ames's failing health. He wants to leave an account of himself for this son who will never really know him. His greatest regret is that he hasn't much to leave them, in worldly terms. "Your mother told you I'm writing your begats, and you seemed very pleased with the idea. Well, then. What should I record for you?" In the course of the narrative, John Ames records himself, inside and out, in a meditative style. Robinson's prose asks the reader to slow down to the pace of an old man in Gilead, Iowa, in 1956. Ames writes of his father and grandfather, estranged over his grandfather's departure for Kansas to march for abolition and his father's lifelong pacifism. The tension between them, their love for each other and their inability to bridge the chasm of their beliefs is a constant source of rumination for John Ames. Fathers and sons.
The other constant in the book is Ames's friendship since childhood with "old Boughton," a Presbyterian minister. Boughton, father of many children, favors his son, named John Ames Boughton, above all others. Ames must constantly monitor his tendency to be envious of Boughton's bounteous family; his first wife died in childbirth and the baby died almost immediately after her. Jack Boughton is a ne'er-do-well, Ames knows it and strives to love him as he knows he should. Jack arrives in Gilead after a long absence, full of charm and mischief, causing Ames to wonder what influence he might have on Ames's young wife and son when Ames dies.
These are the things that Ames tells his son about: his ancestors, the nature of love and friendship, the part that faith and prayer play in every life and an awareness of one's own culpability. There is also reconciliation without resignation, self-awareness without deprecation, abundant good humor, philosophical queries--Jack asks, "'Do you ever wonder why American Christianity seems to wait for the real thinking to be done elsewhere?'"--and an ongoing sense of childlike wonder at the beauty and variety of God's world.
In Marilynne Robinson's hands, there is a balm in Gilead, as the old spiritual tells us. --Valerie Ryan

Product Description
The Stories and art in this volume of whimsey share one important element. All were generously contributed in an effort to aid the victims of terror in northern Israel. Many of these artists are the leading voices of their respective genres-their politics and points of view vary sufficiently to create a stout dialogue. The result of their joining is BALM IN GILEAD, a delicious anthology of artistic speculations and meditations that, despite theological nuances, move beyond the boundaries of culture to join in a single voice of hope.
