About the authors

Lynn Margulis, Distinguished University Professor in the Department of Geosciences at the University of Massachusetts at Amherst, received the 1999 National Medal of Science from President Bill Clinton. She has been a member of the U.S. National Academy of Sciences since 1983 and of the Russian Academy of Natural Sciences since 1997. Author, editor, or coauthor of chapters in more than forty books, she has published or been profiled in many journals, magazines, and books, among them Natural History, Science, Nature, New England Watershed, Scientific American, Proceedings of the National Academy of Sciences, Science Firsts, and The Scientific 100. She has made numerous contributions to the primary scientific literature of microbial evolution and cell biology.
Margulis's theory of species evolution by symbiogenesis, put forth in Acquiring Genomes (co-authored with Dorion Sagan, 2002), describes how speciation does not occur by random mutation alone but rather by symbiotic d©tente. Behavioral, chemical, and other interactions often lead to integration among organisms, members of different taxa. In well-documented cases some mergers create new species. Intimacy, physical contact of strangers, becomes part of the engine of life's evolution that accelerates the process of change. Margulis works in the laboratory and field with many other scientists and students to show how specific ancient partnerships, in a given order over a billion years, generated the cells of the species we see with our unaided eyes.The fossil record, in fact, does not show Darwin's predicted gradual changes between closely related species but rather the "punctuated equilibrium" pattern described by Eldredge and Gould: a jump from one to a different species.
She has worked on the "revolution in evolution" since she was a graduate student. Over the past fifteen years, Margulis has cowritten several books with Dorion Sagan, among them What is Sex? (1997), What is Life? (1995), Mystery Dance: On the Evolution of Human Sexuality (1991), Microcosmos: Four Billion Years of Evolution from Our Microbial Ancestors (1986), and Origins of Sex:Three Billion Years of Genetic Recombination (1986).
Her work with K.V. Schwartz provides a consistent formal classification of all life on Earth and has lead to the third edition of Five Kingdoms: An Illustrated Guide to the Phyla of Life on Earth (1998). Their classification scheme was generated from scientific results of myriad colleagues and its logical-genealogical basis is summarized in her single-authored book Symbiosis in Cell Evolution: Microbial Communities in the Archean and Proterozoic Eons (second edition, 1993). The bacterial origins of both chloroplasts and mitochondria are now well established. Currently, with colleagues and students, she explores the possible origin of cilia from spirochetes.
Since the mid-1970s, Margulis has aided James E. Lovelock, FRS, in documenting his Gaia Theory, which posits that the Earth's surface interactions among living beings, rocks and soil, air and water have created a vast, self-regulating system. From the vantage of outer space the Earth looks like an amazing being; from the vantage of biochemistry it behaves in many ways like a giant organism.

Dorion Sagan is a celebrated writer, ecological philosopher, and author or coauthor of twenty-five books, which have been translated into fifteen languages (French, Italian, Japanese, Chinese, Dutch, German, Danish, Spanish, Hebrew, French, Portuguese, Turkish, Romanian, Catalan, and Basque). As an ecological theorist he has been at the forefront of bringing our growing understanding of symbiosis as a major force in evolution into the intellectual mainstream, both within science and the humanities, and rethinking the human body as a “multispecies organism.” Sagan has recently continued his lifelong efforts to decenter the human by proposing the concept of Cyanocene in response to the Anthropocene debates (e.g., “Coda: Beautiful Monsters: Terra in the Cyanocene," Arts of Living on a Damaged Planet, University of Minnesota, 2017). A serial collaborator on scientific, intellectual, and artistic projects, Sagan's work ethic follows that of evolving life, whose creativity derives largely from symbiotic merger and genetic recombination. With Carl Sagan and Lynn Margulis, his parents, he is coauthor of the entries for both “Life” and “Extraterrestrial Life” in the Encyclopedia Britannica. The international impact and collaborative character of his work is demonstrated, for example, by the fact that his writing is now regularly used in Japan for college preparation exams. Sagan's close collaborations with multiple scientists from different fields including evolution, ecology, and thermodynamics have helped usher in new, more integral and realistic biological approaches which recognize humanity as a very recent part of a four billion year old biosphere, with important implications for both medicine and the long-term viability of the human species as a planetary life form. His coauthored critiques have helped effect a rapprochement between neo-Darwinism and the biochemistry and microbial ecology of group selection, one bearing fruits for example in the new emphasis among health professionals on the importance of the human microbiome. Sagan has published with university presses (e.g., Yale, Harvard, Oxford, MIT, and University of Chicago), including in anthologies edited by E. O. Wilson and Richard Dawkins in the sciences, and alongside luminaries such as John A. Wheeler, Ursula K. Le Guin, and Jean-Paul Sartre in humanities collections. Increasingly referenced and influential within both academia and popular culture, he is regularly cited by feminist theorists, environmentalists, and drug liberation advocates. Deleuzian political theorist William Connolly of John Hopkins University has described Dorion Sagan’s theorization of teleodynamism (explanations of the world that combine natural forces with micro-agency) as “pursu[ing] these theoretical and experimental lines while actively resisting capture by neoliberalism.” His work has appeared in Natural History, Smithsonian, Wired, Cabinet, and The New York Times, among other publications. He is a member of the Lindisfarne Association and the Advisory Network of Psymposia, as well as on the boards of Sputnik Inc and the Pioneer Valley Coral & Natural Science Institute. Nature magazine named the book to which he contributed, Fine Lines: Vladimir Nabokov’s Scientific Art as one of their Top Twenty books for 2016. In 2014 Kevin Kelly, for The Long Now Foundation, listed his book Biospheres: Metamporphosis of Planet Earth, a Selected Book for the Manual for Civilization. Son of astronomer-educator Carl Sagan and renowned American biologist Lynn Margulis, whose complex work he was the first to popularize, Dorion edited and introduced the 2012 collection, Lynn Margulis: The Life and Legacy of a Scientific Rebel, an IndieFab Award Winner in ForeWord Reviews' Adult Nonfiction Biography category. He contributed to software developer Bill Atkinson’s digital photography book, Within the Stone, an American Photo “Best Photo Book of 2004” in the category of “Art and Science.” In 2003 he was Humana scholar at Centre College in Danville, Kentucky; in 1986 he won an Educational Press Association of America Excellence in Educational Journalism Award for the article, “The Riddle of Sex,” and in 1974 he won Blue Ribbon in the youth contest for sleight of hand in Silent Mora Ring 122, the Boston Chapter of the International Brotherhood of Magicians. He was called an “unmissable modern master” by Stephen Young in New Scientist; Nobel laureate Roald Hoffman tagged his book, Into the Cool: Energy Flow, Thermodynamics, and Life with Eric D. Schneider “fascinating”; and Melvin Konner, in The New York Times, wrote of Microcosmos, coauthored with long-time writing partner Lynn Margulis, that "this admiring reader of Lewis Thomas, Carl Sagan and Stephen Jay Gould has seldom, if ever, seen such a luminous prose style in a work of this kind." What is Life?, also coauthored with Margulis, was included on a list of “Mind-Altering Masterpieces” by the Utne Reader, and was called “A masterpiece of science writing” by Orion magazine. Sagan has also collaborated on books with British neuroscientist John Skoyles, biosphere system theorist Tyler Volk of New York University (Death/Sex), and theoretical biologist, Josh Mitteldorf (Cracking the Aging Code; UK, Australia: What Good is Death?). This last book, “the most original popular science book you’re likely to read this year,” according to Peter D. Kramer, Professor Emeritus of Psychiatry and Human Behavior, Brown University, mounts strong evidence that aging, genetically underlain, tends to prevent fast-growing species from overgrowing their ecosystems. Dorion's current interests include fiction writing, literary criticism, philosophy, and the arts.

This is a fabulous, must-read book on the topic of "what is life", but I highly recommend buying only one copy of this paperback version. Then you need to go to Amazon's secondary sellers and find one or more "used, like new" copies of one of the two hardbound editions. Both of these hardcover editions are more impressive than the newer paperback, one being published in 1995 in London (Great Britain), and the second also being published in 1995, but by Simon & Schuster. Both of these hardcover editions were printed in Italy, by the way. The paperback version is printed on "permanent paper" but the quality, size, artisanship and design of the paperback version is not nearly as impressive as are the two hardbound editions.
This is why I recommend buying just one copy of the newer, compromised paperback (only because some of the scientific nomenclature has been updated), keeping in mind that the larger hardbound originals are so much easier to read and so much more "alive" (ironic, huh, given the title has to do with "life"), that I now find the paperback version to be overpriced and unable to match the awesome overall quality of the original hardbound.
In a sense, this difference in the two versions is much like the arguments that float out there about the relative value of e-books versus "real" books! If you ever wanted to understand the importance of typography, font selection, design, and binding of a book, then find a secondary seller here on Amazon (who has a "used/like new" version of one of the 1995 hardbound versions of this book), and buy that in addition to a copy of the "newer", less visually & emotionally impressive paperback.
By the way, Dorian Sagan comments in May of 2013 that he prefers the London hardcover version, the one printed in Italy. However, I can see no difference between this London (white cover) edition and the Simon & Shuster American edition (also printed in Italy, but with a black cover). Both were printed in 1995, and as far as I can tell they are identical.
But this book is far more than a random collection of facts. Margulis and her collaborators do an amazing job of assembling an understandable model of life using parts carefully selected from a vast body of biological knowledge. While a one-sentence definition is still elusive, the reader builds up a picture of life's most pertinent characteristics, as exhibited by the truly astounding diversity of living things on this planet. By the time I finished, I was satisfied that the authors had answered the question.
You don't need to be a biologist to understand and enjoy this book. Its beauty is that the greatest scientific thinking on the most complex topics has been presented in common english, with necessary scientific terms explained as they are introduced. If you are intrigued by the question of life, I doubt there's a more complete, accurate, understandable, and enjoyable answer available than this book.
an appendage. It is filled with awsome facts and enlightenments.
My only disappointment was that I am just an animal like all others on
this earth and nothing was said concerning what happens to me when
fungi take over. I mean "Me". Where do I go? Right now I beleive I just
plain die. It makes life a bit harder to face, to think all this is gone when
I die. Can anyone recommend a book that will help to give me an idea
as to what happens to my consciousness when I die??
