The Origin Of Life And Process Of Reproduction In Plants And Animals

Excerpt from The Origin of Life and Process of Reproduction in Plants and Animals: With the Anatomy and Physiology of the Human Generative System, Male and Female, and the Causes, Prevention and Cure of the Special Diseases to Which It Is Liable; A Plain, Practical Treatise, for Popular Use AT the commencement of my medical career circumstances led me into the study of the Generative System, its Anatomy, Physiology, and diseases and this became, subsequently, a specialty with me, both as a matter of scientific pursuit and as a particular subject of medical practice. All my life since has been devoted to the same pursuit, and my practice has been almost exclusively connected with diseases of the Reproductive Organs, in men and women. I have therefore had much opportunity for acquiring knowledge on such matters, and have endeavored, as far as I could, to turn that opportunity to good account. By means of careful Observations, both in human beings and animals, and by dis sections and regular experiments in every practicable way, it has always been an Object with me to, learn as much as possible of the great mystery of Generation! This knowledge I sought not only as a medical man, to enable me to mitigate human suffering, or to fulfill legitimate human hopes, but because it, is intensely interesting m itself, and of Immense importance to the human race in many ways.

Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Although plants comprise more than 90% of all visible life, and land plants and algae collectively make up the most morphologically, physiologically, and ecologically diverse group of organisms on earth, books on evolution instead tend to focus on animals. This organismal bias has led to an incomplete and often erroneous understanding of evolutionary theory. Because plants grow and reproduce differently than animals, they have evolved differently, and generally accepted evolutionary views—as, for example, the standard models of speciation—often fail to hold when applied to them. Tapping such wide-ranging topics as genetics, gene regulatory networks, phenotype mapping, and multicellularity, as well as paleobotany, Karl J. Niklas’s Plant Evolution offers fresh insight into these differences. Following up on his landmark book The Evolutionary Biology of Plants—in which he drew on cutting-edge computer simulations that used plants as models to illuminate key evolutionary theories—Niklas incorporates data from more than a decade of new research in the flourishing field of molecular biology, conveying not only why the study of evolution is so important, but also why the study of plants is essential to our understanding of evolutionary processes. Niklas shows us that investigating the intricacies of plant development, the diversification of early vascular land plants, and larger patterns in plant evolution is not just a botanical pursuit: it is vital to our comprehension of the history of all life on this green planet.
