美国生物学家林恩·马古利斯与她的儿子多里昂·萨根（Dorion Sagan）和合著:《性别的起源：基因重组的30亿年》

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

Lynn Margulis is Distinguished University Professor at the University of Massachusetts, Amherst and a member of the National Academy of Sciences. Dorion Sagan is the author of "Biospheres" and coauthor, with Lynn Margulis, of "What Is Life?" (1996).

Eric D. Schneider served as senior scientist at the National Oceanic and Atmospheric Administration and director of the National Marine Water Quality Laboratory of the Environmental Protection Agency. His work on thermodynamics--a topic he has pursued for more than twenty years--has been widely anthologized and cited. Dorion Sagan is coauthor of "Acquiring Genomes" and "Up from Dragons," Called an "unmissable modern master" of science writing by "New Scientist," Sagan has written for the "New York Times," "Natural History," and "Wired," among other publications.
