Descripción editorial
Combining the literary sensibility of David Quammen with the scientific rigor of Stephen Jay Gould, Carl Zimmer reveals the power, danger, and beauty of the surprising creatures who dominate the earth: parasites.
For centuries, parasites have lived in nightmares, horror stories, and the darkest shadows of science. In Parasite Rex, Carl Zimmer takes readers on a fantastic voyage into the secret universe of these extraordinary life-forms—which are not only among the most highly evolved on Earth, but make up the majority of life’s diversity. Traveling from the steamy jungles of Costa Rica to the parasite-riddled war zone of southern Sudan, Zimmer introduces an array of amazing creatures that invade their hosts, prey on them from within, and control their behavior. He also vividly describes parasites that can change DNA, rewire the brain, make men more distrustful and women more outgoing, and turn hosts into the living dead. This comprehensive, gracefully written book brings parasites out into the open and uncovers what they can teach us all about the most fundamental survival tactics in the universe—the laws of Parasite Rex.
PUBLISHERS WEEKLY
One of the year's most fascinating works of popular science is also its most disgusting. From tapeworms to isopods to ichneumon wasps, "parasites are complex, highly adapted creatures that are at the heart of the story of life." Zimmer (At the Water's Edge) devotes his second book to the enormous variety of one- and many-celled organisms that live on and inside other animals and plants. The gruesome trypanosomes that cause sleeping sickness had nearly been routed from Sudan when the country's civil war began: now they're back. Costa Rican researcher Daniel Brooks has discovered dozens of parasites, including flies that lay eggs in deer noses: "snot bots." And those are only the creatures from the prologue. Zimmer discusses how the study of parasites began, with 19th-century discoveries about their odd life cycles. (Many take on several forms in several generations, so that a mother worm may resemble her granddaughter, but not her daughter.) He looks at how parasites pass from host to host, and how they defeat immune systems and vice versa. Many parasites alter their hosts' behavior: Toxoplasma makes infected rats fearless, thus more likely to be eaten by cats, who will then pick up the microbe. Quantifiable "laws of virulence" lead parasites to become nasty enough to spread, yet not so nasty as to wipe out all their hosts. And eons of coevolution can affect both partners: howler monkeys may avoid violent fights because screwworms can render the least scratch fatal. Two final chapters address parasites in human medicine and agriculture. Not only are parasites not all bad, Zimmer concludes in this exemplary work of popular science, but we may be parasites, tooDand we have a lot to learn from them about how to manage earth, the host we share.
