Tireless, controversial, and hugely inspirational to those who knew her or encountered her work, Lynn Margulis was a scientist whose intellectual energy and interests knew no bounds. Best known for her work on the origins of eukaryotic cells, the Gaia hypothesis, and symbiogenesis as a driving force in evolution, her work has forever changed the way we understand life on Earth. When Margulis passed away in 2011, she left behind a groundbreaking scientific legacy that spanned decades. In this collection, Dorion Sagan, Margulis's son and longtime collaborator, gathers together the voices of friends and colleagues to remark on her life and legacy, in essays that cover her early collaboration with James Lovelock, her fearless face-off with Richard Dawkins during the so-called "Battle of Balliol" at Oxford, the intrepid application of her scientific mind to the insistence that 9/11 was a false-flag operation, her affinity for Emily Dickinson, and more. Margulis was elected to the National Academy of Sciences in 1983, received the prestigious National Medal of Science in 1999, and her papers are permanently archived at the Library of Congress. Less than a month before her untimely death, Margulis was named one of the twenty most influential scientists alive - one of only two women on this list, which include such scientists as Stephen Hawking, James Watson, and Jane Goodall.

How do new species evolve? Although Darwin identified inherited variation as the creative force in evolution, he never formally speculated where it comes from. His successors thought that new species arise from the gradual accumulation of random mutations of DNA. But despite its acceptance in every major textbook, there is no documented instance of it. Lynn Margulis and Dorion Sagan take a radically new approach to this question. They show that speciation events are not, in fact, rare or hard to observe. Genomes are acquired by infection, by feeding, and by other ecological associations, and then inherited. Acquiring Genomes is the first work to integrate and analyze the overwhelming mass of evidence for the role of bacterial and other symbioses in the creation of plant and animal diversity. It provides the most powerful explanation of speciation yet given.

A distinguished microbiologist explains the importance of symbiosis - where different organisms contribute to each other's support - and how this is changing our view of life on Earth Lynn Margulis is an ardent supporter of the Gaia hypothesis: the idea that due to the finely balanced interdependence of all life forms, the planet functions as a single, giant cell. She argues that no organism is an island, and that all are linked to each other. Written with tremendous zest and authority The Symbiotic Planet traces the evolution of Earth from the origins of life and sex to the emergence of 'hyperseas' and an eerie future she describes for humanity.

A fascinating and detailed examination of the evolution--and occasional devolution--of sexuality in microorganisms and more complex forms of life. Margulis and Sagan trace sex from its inauspicious beginnings in bacteria threatened by ultraviolet radiation to its intimate relation with the origin of mitotic division of nucleated cells. The origin of meiotic sex through cannibalism followed by centriole reproductive tardiness and the connection of cell symbiosis to sex and differentiation are explored. "The authors have not only given us a new and exiting scenario for the evolution of sex, but have also provided us with critical ways in which we can test their hypotheses. . . . This is a stimulating book that is sure to invoke criticism and discussion; I strongly recommend it."--Symbiosis "The book is well organized and well written, leading the reader from one thought to another almost effortlessly. Background information is presented to aid those of us who are not experts in this field, and a glossary is appended. The book could be used at all levels of study, from interested undergraduates in general biology though postdoctoral students of genetics and evolution. I recommend this thought-provoking book to you for both your enjoyment and your enlightenment."--Richard W. Cheney, Jr., Journal of College Science Teaching "This book, undoubtedly controversial, is a thoughtful and original contribution to an important aspect of cellular biology."--John Langridge

In the first story, "Conceits (Howard)," Ren studies chemistry and dates the monumentally self-absorbed Howard Fein, a medical student whose selfishness results in lifelong repercussions for Ren. Later, in "Gases (Raoul)," Ren has a toxic affair with fellow atmospheric chemist Raoul Gautier, who alternately accepts and rejects her advances. In "The Estimator (Georges)," readers meet Georges Standon, a space scientist haunted by the long-ago disappearance of his wife, Odile.
