On the Origin of Species, published on 24 November 1859, is a work of scientific literature by Charles Darwin which is considered to be the foundation ofevolutionary biology. Its full title was On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution. Darwin included evidence that he had gathered on the Beagle expedition in the 1830s and his subsequent findings from research, correspondence, and experimentation.
This book makes Moore's wisdom available to students in a lively, richly illustrated account of the history and workings of life. Employing rhetoric strategies including case histories, hypotheses and deductions, and chronological narrative, it provides both a cultural history of biology and an introduction to the procedures and values of science.
In this spirited and irreverent critique of Darwin’s long hold over our imagination, a distinguished philosopher of science makes the case that, in culture as well as nature, not only the fittest survive: the world is full of the “good enough” that persist too. Why is the genome of a salamander forty times larger than that of a human? Why does the avocado tree produce a million flowers and only a hundred fruits? Why, in short, is there so much waste in nature? In this lively and wide-ranging meditation on the curious accidents and unexpected detours on the path of life, Daniel Milo argues that we ask these questions because we’ve embraced a faulty conception of how evolution—and human society—really works. Good Enough offers a vigorous critique of the quasi-monopoly that Darwin’s concept of natural selection has on our idea of the natural world. Darwinism excels in accounting for the evolution of traits, but it does not explain their excess in size and number. Many traits far exceed the optimal configuration to do the job, and yet the maintenance of this extra baggage does not prevent species from thriving for millions of years. Milo aims to give the messy side of nature its due—to stand up for the wasteful and inefficient organisms that nevertheless survive and multiply. But he does not stop at the border between evolutionary theory and its social consequences. He argues provocatively that the theory of evolution through natural selection has acquired the trappings of an ethical system. Optimization, competitiveness, and innovation have become the watchwords of Western societies, yet their role in human lives—as in the rest of nature—is dangerously overrated. Imperfection is not just good enough: it may at times be essential to survival.
Charles Darwin's Origin of Species (publ. 1859) is a pivotal work in scientific literature and arguably the pivotal work in evolutionary biology. The book's full title is On the Origin of Species by Means of Natural Selection, or the Preservation of Favoured Races in the Struggle for Life. It introduced the theory that populations evolve over the course of generations through a process of natural selection. It was controversial because it contradicted religious beliefs which underlay the then current theories of biology. Darwin's book was the culmination of evidence he had accumulated on the voyage of the Beagle in the 1830s and added to through continuing investigations and experiments since his return.
DIVReasoned and well-documented in its arguments, this work offers coherent views of natural selection, adaptation, the struggle for existence, survival of the fittest, and other concepts that form the foundation of evolutionary theory. /div

Epigenetics can potentially revolutionize our understanding of the structure and behavior of biological life on Earth. It explains why mapping an organism's genetic code is not enough to determine how it develops or acts and shows how nurture combines with nature to engineer biological diversity. Surveying the twenty-year history of the field while also highlighting its latest findings and innovations, this volume provides a readily understandable introduction to the foundations of epigenetics. Nessa Carey, a leading epigenetics researcher, connects the field's arguments to such diverse phenomena as how ants and queen bees control their colonies; why tortoiseshell cats are always female; why some plants need cold weather before they can flower; and how our bodies age and develop disease. Reaching beyond biology, epigenetics now informs work on drug addiction, the long-term effects of famine, and the physical and psychological consequences of childhood trauma. Carey concludes with a discussion of the future directions for this research and its ability to improve human health and well-being.
"A seminal text in the womenís movement." –Ethel S. Person, author of The Sexual Century "Still the most important work of feminist psychoanalytic exploration, its re-release is a celebratory occasion." –Eli Sagan, author of Freud, Women and Mortality "[The Mermaid and the Minotaur] continues to astonish us with the depth and wisdom of its psychoanalytic approach even as its major ideas have become as unobtrusively essential to psychoanalytic feminism as the atmosphere." –Jessica Benjamin, author of The Bonds of Love
. Renewal of Life by Transmission. The most notable distinction between living and inanimate things is that the former maintain themselves by renewal. A stone when struck resists. If its resistance is greater than the force of the blow struck, it remains outwardly unchanged. Otherwise, it is shattered into smaller bits. Never does the stone attempt to react in such a way that it may maintain itself against the blow, much less so as to render the blow a contributing factor to its own continued action. While the living thing may easily be crushed by superior force, it none the less tries to turn the energies which act upon it into means of its own further existence. If it cannot do so, it does not just split into smaller pieces (at least in the higher forms of life), but loses its identity as a living thing. As long as it endures, it struggles to use surrounding energies in its own behalf. It uses light, air, moisture, and the material of soil. To say that it uses them is to say that it turns them into means of its own conservation. As long as it is growing, the energy it expends in thus turning the environment to account is more than compensated for by the return it gets: it grows. Understanding the word "control" in this sense, it may be said that a living being is one that subjugates and controls for its own continued activity the energies that would otherwise use it up. Life is a self-renewing process through action upon the environment.
