Book Overview

Evolution is not merely the process that ruled the rise and fall of the dinosaurs over hundreds of millions of years. It also happens rapidly, so quickly and so frequently that it changes how all of us live our lives. Drugs fail because diseases like HIV and tuberculosis evolve in a matter of months, neatly sidestepping pharmacology. Insects adapt and render harmless the most powerful pesticides in a matter of years, not centuries. While the ecological...

Science writing that will make creationists cringe.

This excellently-done book explores the human tendency to cause explosive evolution in our environments. Don't believe in evolution? Note how effectively we've caused many disease organisms to evolve resistance to our best antibiotics, in the course of less than 100 years. Or the fact that all of our food and pets have been selectively bred to exacting standards for more than 10,000 years. If we hadn't accelerated the evolution of maize, we'd still be eating cobs less than an inch long, you know. So there. And to counter your arguments: yes, selective breeding is too evolution. It's evolution by artificial selection, which is a perfectly valid mechanism. So there again.Palumbi is both a colorful and informative writer. He spends a lot of time discussing HIV, and why it's so hard to beat (it mutates constantly, overwhelming the immune system). I would have liked a more in-depth discussion about whether humans are still evolving or not -- I think we are -- but he only touched on that subject. Nonetheless, highly recommended.

Why evolution Matters and why you should care.

This is a great read. Steven Palumbi shows everyone why evolution matters today in real and meaning ful ways.Two quotes from the book".. the best education is the one that bites back, the one that shows with clarity of glacial ice that the facts and principles of the scientific world are of crucial importance to every day life.... not through eclectic recourse to scientific theory or historical anecdote. Instead, I need to do it through examples about how evolution in the world around us matters." And why does it matter: " And if antibiotic resistance just happens, then we have no notion of how it comes to be, and no real chance to block the rise of some of the world's deadliest forms of life. But if something evolves, then the science of evolution can chart the answer to why, and perhaps prevent or change it."

Colorful take on how we cause unwanted evolutionary change

It has become clear over the last few decades that evolution can take place much more rapidly than Darwin ever imagined. The evolution of the AIDS virus is a particularly compelling case in point, and one of the focal points of this engaging book about how our efforts to control our world can bring about unwanted evolutionary change over time periods measured not in millennia, but in weeks and months. Mostly it is microbial evolution that Harvard Professor of Biology Stephen Palumbi writes about, the AIDS virus, the bacteria that cause tuberculosis, staph and other infections, but also insects and plants, particularly the insects that eat crops and the plants we call weeds, and even fish. At the center of change is the "evolutionary engine" that is continually at work adjusting organisms to their environments. Change the environment of a creature and the creature changes to keep its fit, a never-ending phenomenon that frustrates our efforts to eradicate harmful pests and deadly diseases.Palumbi shows how it is not enough to spray our fields of amber grain with pesticides because the pests will inevitably evolve to flourish in the new pesticide-filled environment. It is not enough to throw antibiotics at the bacteria that invade our bodies because they too will evolve to flourish. Our efforts to combat the scourges of field and body are now seen as just one half of the prey/predator, parasite/host phenomenon of co-evolution. As Palumbi phrases it, "The disease dance continues, turning to the evolutionary tune, and both players must step smartly." (p. 90) We must take the power of life forms to evolve rapidly into account, and realize that they will react to our efforts. This is the evolutionary arms race, the "Red Queen" hypothesis, that keeps us (if we "step smartly"enough) and our enemies in the same place even though we are both running at full speed. This may be seen as a kind of cosmic joke at those who would find "progress" in evolution.En route on bringing us up to speed on rapid evolutionary change, Palumbi sets some sort of record for the use of colorful language. There is some distraction as metaphors and analogies fly about like confetti at a wedding , but he is so clever that we forgive him. Some examples: p 16: "...as unknown as the dreams of a sleeping infant."p. 56: a trait (a recessive gene) is said to lie "dormant like thoughts on a Saturday morning."p. 102: a virus is compared to a credit card.p. 107: a typical viral attack on the immune system "has more plot twists than a soap opera."p. 137: expressing the too-optimistic hopes of a five-year malaria eradication program: "...by then, surely malaria would be gone like the world's last car payment."p. 240: "bad ideas" are compared to "anchovy daiquiris" that "live on only in a few people with fishy breath."In short, this book colorfully illuminates one of the most significant conundrums of our time: despite our best pesticides, our most powerful antibiotics, our m

Humans impact evolution

"The Evolution Explosion" by Stephen R. Palumbi, New York: W.W. Norton & Co., Inc., 2001.By David LiscioAnyone seeking an eloquent explanation of recent evolution as it relates to human impact -- from the use of herbicides, pesticides and antibiotics to AIDS treatment and genetic manipulation -- should find "The Evolution Explosion" a worthwhile read. Harvard University biology professor Dr. Stephen R. Palumbi has written what is essentially a text on fast-paced evolution, in a style more akin to travel and adventure books, yet packed with scientific detail. From the start, he explains that the task is "to bring home the equally common impact of evolution on daily life - and not through eclectic recourse to scientific theory or historical anecdote. Instead, I need to do it through examples about how evolution in the world around us matters." To make his point, Palumbi refers to the fertile soils of Kansas that "are part of the everyday life of millions of people - and billions of insects and weeds. And evolution lives among the fields and stalks the checkbooks of struggling farmers - here, like everywhere else, living in the many weed and insect species that have evolved resistance to pesticides." Palumbi notes that as long ago as 1954, a young Paul Ehrlich studied the impact of DDT and evolution of flies that would survive and resist the deadly chemical. As the author explains, Ehrlich's famous work, "The Population Bomb," is partially a result of "the DDT dustings (Ehrlich) and his future wife endured at drive-in movie theaters during Kansas' aborted attempt at mosquito eradication." Consider this: American troops during WWII dusted themselves and civilians with a white powder. In 1944, entire neighborhoods of Italian villages were coated to keep typhus-bearing lice in check. The epidemic was soon declared dead. "But complete victory was short-lived, and only a year later, DDT-resistant insects were reported," Palumbi writes. "By 1946, houseflies in Sweden were resistant, and by 1951, mosquitoes and flies in Italy were resistant not only to DDT but also to a wide range of the new pesticidal chemicals like chlordane, methoxychlor, and heptachlor." The author adds that both Egypt and the U.S. used DDT to control mosquito-borne malaria from 1947-52, even though the disease was already on the decline because of extensive dredging. It is yet another example of attempts by human to intervene and, ultimately, speed up the natural evolutionary process. Palumbi, 44, who in 1996 relocated his laboratory after 11 years from the University of Hawaii to Harvard, articulately lays out the issues surrounding AIDS treatment, the use of antibiotics, and the genetic "tinkering" linked to the fight against crop-destroying diseases, all framed in terms of evolutionary speed. The researcher most recently caused a stir in the scientific community by using molecular genetics to show that the meat of a certain

Key Perspectives on How Technology Accelerates Evolution

Not everyone believes that evolution occurs, even though examples exist all around us (such as antibiotic-resistant strains of bacteria). Recent studies show us that the evolution that took millions in years in the geological record now happens in months or years. What's changed? Basically, human intervention into the biological environment is becoming the driving force for evolution on earth. This outstanding book outlines this process, and argues that the process will only speed up in the future as ideas develop faster and proliferate more rapidly. Learning how to manage evolution to our benefit is our next key challenge. It is even more important than genetic engineering, because that field will trigger much inintended evolution (as it already has).The book begins with a trip to Hawaii to rescue some rare snails for captive breeding. Along the way, many examples of human-driven evolution are observed. From there, Professor Palumbi looks at the rise of antibiotic-resistant bacteria. These strains arise in 1 to 36 years after a new antibiotic is released. Historically, it seems that bacteria tried to kill other bacteria in similar ways, so there are genetic variation escape hatches. He points out that using multiple antiobiotics can be an effective strategy for avoiding this problem. On the other hand, many diseases once thought to be under control {like tuberculosis) are on the rise again. The HIV story is much more complex and interesting. HIV uniquely evolves in each body it invades. A better solution may be to encourage HIV to evolve in harmless ways rather than to kill it.New bioengineered plants try to poison insects with genetic alterations. Unless farmers keep low-yield refuges, this will simply create poison-resistant insects and pests. The potential danger to our food supply is enormous. Overkill with poisons is not a good solution for a variety of obvious reasons.A lot of biotechnology development is not considering the evolution that these innovations will create. That gap needs to be filled.The ocean is then used as an example of how over fishing has created permanently smaller fish who grow more slowly. Without changing our approach, the sea will become a very small source of food. The book then looks at whether humans are still evolving, and points to evidence that some diseases may be related to resistance to other diseases (cystic fibrosis recessive genes may help with avoiding typhoid). The most interesting part of the book is in the final chapter. It talks about the evolution of ideas and their spread. It points out that ideas can evolve faster and be retained longer than evolutionary shifts. This is our key armament in the evolutionary conflicts. The book briefly reviews the thoughts of Richard Dawkins and Stephen Pinker to suggest different approaches to the subject. I suggest that you read more of Dawkins if you have not already. After you finish this book, start to use the metaphor of human-caus
