Book Overview

There are over one billion organisms in a pinch of soil, yet we know much more about deep space than about the universe below. In Tales from the Underground, Cornell ecologist David Wolfe takes us on a tour through current scientific knowledge of the subterranean world. We follow the progress of discovery from Charles Darwin's experiments with earthworms, to Lewis and Clark's first encounter with prairie dogs, to the use of new genetic tools that...

Wow!

This book really opened my eyes to the subterranean world and I just fell in love. Wolfe is a fantastic author.

Great introduction to subterranean life

_Tales from the Underground_ by David W. Wolfe is an excellent though rather brief introduction to the organisms that live underground; it is only 188 pages long, 206 if one count's the end notes and bibliography (which are quite worthwhile to at least browse). One of the things I liked about the book was that Wolfe was clearly enthusiastic about his subject and expressed a real sense of wonder for the fascinating organisms that dwell under the earth's surface. He began the book with a nice overall introduction to the subject, more than sufficient to grab my attention. In one just pinch of soil from your backyard, you will be holding close to one billion individual living organisms, including quite a few that are not named, classified, or in any way studied, animals ranging in size from the tiniest of microbes to microscopic threads of fungal hyphae, the total length of which might be best measured in miles, not inches. In a handful of soil there are more creatures than humans currently alive. A typical square yard of soil contains billions of microscopic roundworms called nematodes, a dozen to several hundred earthworms, 100,000 to 500,000 insects and other arthropods, and staggering numbers of single-celled organisms. After reviewing some basics about soil layers and types, he went into more detail about this subterranean world. The first chapter discussed the origins of life on earth, much of which had to do with life in the soil. The complex structure and chemistry of clay crystals may have played a vital role in the development of life, perhaps initially serving as the "infrastructure" of the first, most primitive organisms, this infrastructure eventually being discarded as more and more organic molecules such as those in amino and nucleic acids took over clay's replication and synthesis functions. According to some theorists clay made possible the very first sequencing of simple proteins and genes thanks to its unique properties. Chapter two introduced the "extremophiles," organisms that live in hostile environments, many of which exist in subterranean conditions. Some organisms "breathe in" iron oxide (rust) as a substitute for oxygen, while others are able to incorporate cobalt and even uranium into their biological processes. Much of the chapter gave the history of the study of extremophiles, as biologists continually had to revise their notions of what life could tolerate as they found organisms living at ever higher temperatures and depths (with organism at 9,000 foot depths and at temperatures higher than 160 degrees Fahrenheit having been discovered). Of further interest, these organisms may be the most common in the world, with some calculations showing that their total biomass exceeds that of all surface life. Study of one group, lithotrophic microbes, which live buried in basalt rock deep beneath the surface, has been vital in the search for life on other planets. Chapter three focused primarily on Dr. Carl Woese of the

Examines unexplored terrain

This natural history of subterranean life examines unexplored terrain and its unique and varied habitats, from microscopic life to small water bears. Particularly intriguing are the links made between subterranean life and its potentials for assisting mankind.

Fascinating exploration; very readable

A sea change in our attitude toward life has occurred in recent years owing to the discovery of extremophiles, microorganisms that can live in extreme environments such as the scalding waters of Yellowstone Park or deep under the ocean near vents of molten rock, or simply underground. These life forms, previously unknown, are now believed by some to constitute a majority of the shear weight of life on this planet. That life can exist without oxygen has long been known (indeed the first life forms lived without oxygen), but to exist without the products of photosynthesis, at least the indirect products, was thought impossible. Now we know that some life forms can use purely chemical means for obtaining energy, and do not need sunlight at all.David W. Wolfe, Associate Professor of Plant Ecology at Cornell, fired by his own enthusiasm for things extreme and underground, explores these ideas and findings in a captivating way in this informative book. He begins with the soil, what it is made of, how it was formed. "In a handful of typical healthy soil there are more creatures than there are humans on the entire planet," he advises us on page one. He explores the relationship between mycorrhizal fungi and their above ground symbionts, noting that within that same handful of soil there are "hundreds of miles of fungal threads." There are also within one square yard of soil "billions of microscopic roundworms called nematodes, anywhere from a dozen to several hundred of the much larger earthworms, and 100,000 to 5000,000 insects and other arthropods." He points out that many of these creatures "defy classification; they simply have never been seen before." (p. 2)One of the problems that scientists encounter in trying to study the microorganisms of the soil is that they can't culture them in the lab. "They can't survive when isolated from their neighbors," Wolfe writes. And therein lies perhaps the central tale of this extremely interesting book, namely that we are all of an ecology here on this planet earth, and the interactions and mutualisms and co-dependencies of our existence are as yet only dimly perceived. Remember the biosphere experiment in the Arizona desert some years ago? It failed because the participants had no idea how to create a self-sustaining ecosystem mainly because they were ignorant of the work of the myriad creatures that live in, on, and under the soil.Wolfe explores the relatively new (and very exciting) idea that life on earth did not begin in something like Darwin's warm pond, but instead deep underground, safe and secure from the horrendous activities on the surface. This idea is what is currently firing our excitement about exploring under the surface of Mars and some of the moons of the gas giants in search of the life that we now know might exist there. He looks into clay as the precursor of bio-replication, and as a catalyst, showing how clay crystals "have an organized structure" that is "heritable just as th

Superior Science Writing For The General Public

Dr. Wolfe has written a book which is at once absolutely fascinating and tremendously fun to read. It begins as a study of how life originally began on Earth (not on the surface of the planet, it now seems clear) and proceeds to examine a series of subteranean topics which although obscure perhaps to most land dwellers, affect us all in critically significant ways.Wolfe develops his tour of subsurface life with both scientific rigor and a highly entertaining ability to relate the human dimension behind the discoveries reported within these pages. Thus, for example, we come to learn that Darwin spent his later years consumed with an interest in the 'lowly' earthworm. And we are informed of the way in which Carl Woese, labouring diligently for decades in isolation in a university laboratory, brilliantly worked out the details of his discovery of an entirely new domain of life. Which perforce led to a radical reformulation of our notion of how all life evolved from the most primitive (microscopic) organisms into the more highly developed forms with which we are all familiar today.Tales From The Underground was compiled in the finest tradition of science writing made accessible and informative for a lay audience. And its subject matter is riveting and timely. Especially given how heavily we humans seem to tread on, and interfere with, the subtle development of organic processes that have taken billions of years to evolve on our planet Earth.

Surprises Down Below

According to David W. Wolfe, you are probably guilty of a form of chauvinism you didn't even know existed, "surface chauvinism." You know there are roots down there, and you have seen earthworms, but other than those, you may not have any appreciation for just how complicated things are beneath your feet. Wolfe, who does research in soil conservation and biodiversity, has set out to increase appreciation for his world, in Tales from the Underground: A Natural History of Subterranean Life (Perseus Publishing). Not only can you stop being a surface chauvinist, but by reading this book you will have a foundation in some radically new biological ideas that are changing foundations of science.In these pages, you will meet Dr. Carl Woese, who in 1976 suspected that the lowly methane-producing soil bacterium he was examining was something entirely different. He started doing analyses on the nucleic acid (specifically, RNA) in the creatures, and confirmed that they were more different from regular bacteria than humans are from redwood trees. He had not found a new species, but an entirely new superkingdom of organisms. You will become acquainted with microbial communities thousands of feet down, who thrive in hot temperatures, dark, high pressure, and lack of oxygen. They feed on oil or other carbon sources, or on hydrogen in the rocks. One of the results of these findings is that they seem to make the possibility of life on other planets more likely; it used to be that we looked for planets that had just about the same sunlight, water, and so on as our own, but this was another example of chauvinism. You will find out just how the lowly fungus has an intimate and essential relation to the roots of almost every plant, and about prairie dogs, and other animals digging around underneath.Of course earthworms get a chapter in this enjoyable book, and the chapter is especially enjoyable because it concentrates on the work of Charles Darwin. Darwin has other claims to fame, but his last published work was on the humble earthworm. He studied them for decades, and even did an experiment of spreading chalk over a field and returning twenty-nine years later to see how much soil and vegetable mould had been brought up by the earthworms (six inches). The mild and tentative Darwin could not avoid controversy even in his ardent work on earthworms. Before his work, earthworms were regarded as garden pests which ate up the roots of plants, and though we now value earthworms, it took a while for their reputation to change.Wolfe shows how soils are generally suppressants of disease (Selman Waksman was a soil biologist who found microbes that produced streptomycin), how bioremediation can be affected by humble bacteria or fungi that tie up heavy metals or clean up oil spills, and how by working with, rather than against, the millions of species within the earth, we might reclaim soil and reduce global warming.
