Book Description
At a glance, most species seem adapted to the environment in which they live. Yet species relentlessly evolve, and populations within species evolve in different ways. Evolution, as it turns out, is much more dynamic than biologists realized just a few decades ago. In Relentless Evolution, John N. Thompson explores why adaptive evolution never ceases and why natural selection acts on species in so many different ways. Thompson presents a view of life in which ongoing evolution is essential and inevitable. Each chapter focuses on one of the major problems in adaptive evolution: How fast is evolution? How strong is natural selection? How do species co-opt the genomes of other species as they adapt? Why does adaptive evolution sometimes lead to more, rather than less, genetic variation within populations? How does the process of adaptation drive the evolution of new species? How does coevolution among species continually reshape the web of life? And, more generally, how are our views of adaptive evolution changing? Relentless Evolution draws on studies of all the major forms of life—from microbes that evolve in microcosms within a few weeks to plants and animals that sometimes evolve in detectable ways within a few decades. It shows evolution not as a slow and stately process, but rather as a continual and sometimes frenetic process that favors yet more evolutionary change.

Book Description
Development and Evolution surveys and illuminates the key themes of rapidly changing fields and areas of controversy that the redefining the theory and philosophy of biology. It continues Stanley Salthe's investigation of evolutionary theory, begun in his influential book Evolving Hierarchical Systems, while negating the implicit philosophical mechanisms of much of that work. Here Salthe attempts to reinitiate a theory of biology from the perspective of development rather than from that of evolution, recognizing the applicability of general systems thinking to biological and social phenomena and pointing towards a non-Darwinian and even a postmodern biology.

Book Description
This book is written as an addition to Darwin's work and that of molecular biologists on evolution so as to include views of it from the point of view of chemistry rather than just from our knowledge of the biology and genes of organisms. By concentrating on a wide range of chemical elements, not just those in traditional organic compounds, we show that there is a close relationship between the geological or environmental chemical changes from the formation of Earth and those of organisms from the time of their origin. These are considerations which Darwin or other scientists could not have explored until very recent times since sufficient analytical data were not available. They lead us to suggest that there is a combined geo- and bio-chemical evolution, that of an ecosystem, which has had a systematic chemical development. In this development the arrival of new very similar species is shown to be by random Darwinian competitive selection processes such that a huge variety of species coexist with only minor differences in chemistry and advantages. This is in agreement with previous studies. On the large scale of evolution of very different organisms, and over greater timescales, by way of contrast, we observe that groups of species have special, different, chemical features and function. It is more difficult to understand how they evolved and therefore we examine their chemical development in detail. Overall there is a cooperative evolution of a chemical system driven by capture of energy, mainly from the sun, and its degradation in which the chemistry of both the environment and organisms are facilitating intermediates. We shall suggest that the overall drive of the whole joint system is to optimise the rate of this energy degradation. Since the environmental changes are inorganic and relatively fast they move inevitably to equilibrium. The living part of the system, the organisms, under the influence of this inevitable environmental change are forced to follow but as they are increasingly energised and their reactions are slow, they move further away from equilibrium. We are able to explore the ways in which this chemical system evolved, recognising that as complexity of the chemistry of organisms increased, they had to be formed from more and more compartments and to become part of a chemically cooperative overall activity. They could not remain as isolated species. Only in the last chapter do we attempt to make a connection between the changing chemistry of organisms with the coded molecules of each cell which have to exist to explain reproduction.

Book Description
There is still widespread disagreement among historical linguists about how, or whether, syntactic reconstruction can be done. This book presents a comprehensive methodology for syntactic reconstruction, grounded in a constructional understanding of language. The author then uses that methodology to reconstruct Proto-Sogeram, the ancestor to ten languages in Papua New Guinea. Chapters are devoted to phonology, lexicon, verbal morphosyntax, nominal morphosyntax, and syntactic constructions. The work culminates in a sketch of Proto-Sogeram grammar. Based largely on the author's original fieldwork, this is an innovative application of a novel methodology to new data, and the most complete reconstruction of a Papuan proto-language to date. It will be of interest to scholars of language change, language reconstruction, typology, and Papuan languages.

Book Description
The epic story of our evolution in seven big steps! How did we become who we are? With trademark wit, acclaimed science writer Pamela S. Turner breaks down human evolution into the seven most important steps leading to Homo sapiens. How, when, and why did we: 1.stand up, 2.smash rocks, 3.get swelled heads, 4.take a hike, 5.invent barbecue, 6.start talking (and never shut up), and 7.become storytellers? This fascinating, wickedly funny account of our evolutionary journey turns science into an irresistible story. Vetted by experts at the Smithsonian's Human Origins Program, the book also features incredibly detailed portraits by celebrated paleo-artist John Gurche that bring our early ancestors to life.

Book Description
This illuminating volume explores the effects of chance on evolution, covering diverse perspectives from scientists, philosophers, and historians. The evolution of species, from single-celled organisms to multicellular animals and plants, is the result of a long and highly chancy history. But how profoundly has chance shaped life on earth? And what, precisely, do we mean by chance? Bringing together biologists, philosophers of science, and historians of science, Chance in Evolution is the first book to untangle the far-reaching effects of chance, contingency, and randomness on the evolution of life. The book begins by placing chance in historical context, starting with the ancients and moving through Darwin to contemporary biology. It documents the shifts in our understanding of chance as Darwin’s theory of evolution developed into the modern synthesis, and how the acceptance of chance in Darwinian theory affected theological resistance to it. Other chapters discuss how chance relates to the concepts of genetic drift, mutation, and parallel evolution—as well as recent work in paleobiology and the experimental evolution of microbes. By engaging in collaboration across biology, history, philosophy, and theology, this book offers a comprehensive overview both of the history of chance in evolution and of our current understanding of the impact of chance on life.

Book Description
Over two dozen Christian leaders describe how they changed their minds about evolution Perhaps no topic appears as potentially threatening to evangelicals as evolution. The very idea seems to exclude God from the creation the book of Genesis celebrates. Yet many evangelicals have come to accept the conclusions of science while still holding to a vigorous belief in God and the Bible. How did they make this journey? How did they come to embrace both evolution and faith? Here are stories from a community of people who love Jesus and honor the authority of the Bible, but who also agree with what science says about the cosmos, our planet and the life that so abundantly fills it. Among the contributors are Scientists such as: Francis Collins Deborah Haarsma Denis Lamoureux Theologians and philosophers such as: James K. A. Smith Amos Yong Oliver Crisp Biblical scholars such as: N. T. Wright Scot McKnight Tremper Longman III Pastors such as: John Ortberg Ken Fong Laura Truax
