One of Britain's foremost astrobiologists offers an accessible and game-changing account of life on Earth. __________________ Why is all life based on carbon rather than silicon? And beyond Earth, would life - if it exists - look like our own? __________________ The puzzles of life astound and confuse us like no other mystery. But in this groundbreaking book, Professor Charles Cockell reveals how nature is far more understandable and predictable than we would think. Breathing new life into Darwin's theory of natural selection, The Equations of Life puts forward an elegant account of why evolution has taken the paths it has. In a captivating journey into the forces that shape living things on Earth, Cockell explains that the fundamental laws of physics constrain nature at every turn. Fusing the latest in scientific research with fascinating accounts of the creatures that surround us, this is a compelling argument about what life can - and can't - be.

On Human Nature: Biology, Psychology, Ethics, Politics, and Religion covers the present state of knowledge on human diversity and its adaptative significance through a broad and eclectic selection of representative chapters. This transdisciplinary work brings together specialists from various fields who rarely interact, including geneticists, evolutionists, physicians, ethologists, psychoanalysts, anthropologists, sociologists, theologians, historians, linguists, and philosophers. Genomic diversity is covered in several chapters dealing with biology, including the differences in men and apes and the genetic diversity of mankind. Top specialists, known for their open mind and broad knowledge have been carefully selected to cover each topic. The book is therefore at the crossroads between biology and human sciences, going beyond classical science in the Popperian sense. The book is accessible not only to specialists, but also to students, professors, and the educated public. Glossaries of specialized terms and general public references help nonspecialists understand complex notions, with contributions avoiding technical jargon.

Genes and Evolution, the latest volume in the Current Topics in Developmental Biology series, covers genes and evolution, with contributions from an international board of authors. The chapters provide a comprehensive set of reviews covering such topics as genes and plant domestication, gene networks, phenotypic loss in vertebrates, reproducible evolutionary changes, and epithelial tissue.

Dramatic advances in computing power enable simulation of DNA sequences generated by complex microevolutionary scenarios that include mutation, population structure, natural selection, meiotic recombination, demographic change, and explicit spatial geographies. Although retrospective, coalescent simulation is computationally efficient-and covered here-the primary focus of this book is forward-in-time simulation, which frees us to simulate a wider variety of realistic microevolutionary models. The book walks the reader through the development of a forward-in-time evolutionary simulator dubbed FORward Time simUlatioN Application (FORTUNA). The capacity of FORTUNA grows with each chapter through the addition of a new evolutionary factor to its code. Each chapter also reviews the relevant theory and links simulation results to key evolutionary insights. The book addresses visualization of results through development of R code and reference to more than 100 figures. All code discussed in the book is freely available, which the reader may use directly or modify to better suit his or her own research needs. Advanced undergraduate students, graduate students, and professional researchers will all benefit from this introduction to the increasingly important skill of population genetic simulation.

Mendel's groundbreaking paper, which laid the foundation for further research upon heritage and genetics, is published here complete with the original illustrations and charts. When Mendel released this paper in 1865, it was after years of rigorous study and comparison in plant specimens and their offspring. His conclusion that variant traits were hereditary and could be determined, with a good degree of accuracy, through probability analysis were revolutionary in natural science at the time. Mendel's assertions regarding acquired characteristics, demonstrated through the comparison of peas and their seeds, would spark great interest in the nature and mechanisms behind heredity between generations of organisms. Seeking to gain high quality results, Mendel prefaces his explanations by noting that he artificially fertilized the plants described in the work.

Our species long lived on the edge of starvation. Now we produce enough food for all 7 billion of us to eat nearly 3,000 calories every day. This is such an astonishing thing in the history of life as to verge on the miraculous. "The Big Ratchet" is the story of how it happened, of the ratchets--the technologies and innovations, big and small--that propelled our species from hunters and gatherers on the savannahs of Africa to shoppers in the aisles of the supermarket.
The Big Ratchet itself came in the twentieth century, when a range of technologies--from fossil fuels to scientific plant breeding to nitrogen fertilizers--combined to nearly quadruple our population in a century, and to grow our food supply even faster. To some, these technologies are a sign of our greatness; to others, of our hubris. MacArthur fellow and Columbia University professor Ruth DeFries argues that the debate is the wrong one to have. Limits do exist, but every limit that has confronted us, we have surpassed. That cycle of crisis and growth is the story of our history; indeed, it is the essence of "The Big Ratchet." Understanding it will reveal not just how we reached this point in our history, but how we might survive it.

The terrestrial organisms of the Galapagos Islands live under conditions unlike those anywhere else. At the edge of a uniquely rich mid-ocean upwelling, their world is also free of mammalian predators and competitors, allowing them to live unbothered, exuberant lives. With its giant tortoises, marine iguanas, flightless cormorants, and forests of giant daisies, there's no question that this is a magnificent place. Long before people traversed the Earth, evolution endowed native species with adaptations to these special conditions and to perturbations like El Nino events and periodic droughts. As the islands have grown ever-more connected with humanity, those same adaptations now make its species vulnerable. Today, the islands are best viewed as one big social-ecological system where the ability of each native organism to survive and reproduce is a product of human activity in addition to ecological circumstances. In this book, William H. Durham takes readers on a tour of Galapagos and the organisms that inhabit these isolated volcanic islands. Exuberant Life offers a contemporary synthesis of what we know about the evolution of its curiously wonderful organisms, how they are faring in the tumultuous changing world around them, and how evolution can guide our efforts today for their conservation. The book highlights the ancestry of a dozen specific organisms in these islands, when and how they made it to the Galapagos, as well as how they have changed in the meantime. Durham traces the strengths and weaknesses of each species, arguing that the mismatch between natural challenges of their habitats and the challenges humans have recently added is the main task facing conservation efforts today. Such analysis often provides surprises and suggestions not yet considered, like the potential benefits to joint conservation efforts between tree finches and tree daisies, or ways in which the peculiar evolved behaviors of Nazca and blue-footed boobies can be used to benefit both species today. In each chapter, a social-ecological systems framework is used to highlight links between human impact, including climate change, and species status today, Historically, the Galapagos have played a central role in our understanding of evolution; what these islands now offer to teach us about conservation may well prove indispensable for the future of the planet.

A wildly fun and scientifically sound exploration of what alien life must be like Scientists are confident that life exists elsewhere in the universe. Yet rather than taking a realistic approach to what aliens might be like, we imagine that life on other planets is the stuff of science fiction. The time has come to abandon our fantasies of space invaders and movie monsters and place our expectations on solid scientific footing. Using his own expert understanding of life on Earth and Darwin's theory of evolution--which applies throughout the universe--Cambridge zoologist Dr. Arik Kershenbaum explains what alien life must be like: how these creatures will move, socialize, and communicate. Might there be an alien planet with supersonic animals? A moon where creatures have a language composed of smells? Will aliens scream with fear, act honestly, or have technology? The Zoologist's Guide to the Galaxy answers these questions using the latest science to tell the story of how life really works, on Earth and in space.
