""How many creatures walking on this earth / Have their first being in another form?" the Roman poet Ovid asked two thousand years ago. He could not have known the full extent of the truth: Today, biologists estimate a stunning three-quarters of all animal species on earth undergo some form of metamorphosis. But why do tadpoles transform into frogs, caterpillars into butterflies, elvers into eels, immortal jellyfish from sea sprigs to medusae and back again, growing younger and younger in frigid ocean depths? Why must creatures go through massive destruction and remodeling to become who they are? Tracing a path from Aristotle--who rejected the possibility of metamorphosis--to Darwin to today, historian of science Oren Harman explores that central mystery. Metamorphosis, however, isn't just a biological puzzle: It takes us to the very heart of questions of being and identity, whatever kind of change we may undergo. Metamorphosis is a new classic of natural history: a book that, by unveiling a mystery of nature, causes us to relearn ourselves"--Publisher's description.

"The newest addition to John Brockman's Edge.org series explores life itself, bringing together the world's leading biologists, geneticists, and evolutionary theorists -- including Richard Dawkins, Edward O. Wilson, J. Craig Venter, and Freeman Dyson. Scientists' understanding of life is progressing more rapidly than at any point in human history, from the extraordinary decoding of DNA to the controversial emergence of biotechnology. Featuring pioneering biologists, geneticists, physicists, and science writers, Life explains just how far we've come -- and takes a brilliantly educated guess at where we're heading. Richard Dawkins and J. Craig Venter compare genes to digital information, and sketch the frontiers of genomic research. Edward O. Wilson reveals what ants can teach us about building a superorganism -- and, in turn, about how cells build an organism. Elsewhere, David Haig reports new findings on how mothers and fathers individually influence the human genome, while Kary Mullis covers cutting edge treatments for dangerous viruses. And there's much more in this fascinating volume. We may never have all the answers. But the thinkers collected in Life are asking questions that will keep us dreaming for generations."--provided by Amazon.com.

Darwin provoked Jews as well as Christians, and this book examines leading nineteenth- and early twentieth-century American progressive Jewish thinkers who wrestled with evolutionary theories. In particular there was a widespread commitment to the application of biological evolutionary theory to history and cosmology, and a fascination with the evolution of ethical systems within human societies, bearing in mind mankind's bestial origins and new challenges for understanding religious traditions. It is argued that Reform Jewish discussions about the nature of God have been more profoundly shaped by engagement with evolutionary theory than has been recognized before and that, in fact, evolutionary thought provides the key conceptual framework for understanding the distinctive development of Reform Judaism in North America. --
