The Teeth of Non-Mammalian Vertebrates: Dentitions for Form, Function, and Feeding, Second Edition is devoted to the teeth and dentitions of living fishes, amphibians, and reptiles. This book presents a comprehensive survey of the wide variety of tooth forms among non-mammalian vertebrates, based on descriptions of approximately 450 species belonging to about 170 families.This latest edition discusses the functional morphology of feeding, the attachment of teeth, and the relationship of tooth form to function, with each chapter accompanied by a comprehensive, up-to-date reference list. Following the descriptions of the teeth and dentitions in each class, four chapters review current topics with considerable research activity: tooth development; tooth replacement; and the structure, formation, and evolution of the dental hard tissues. The Teeth of Non-Mammalian Vertebrates: Dentitions for Form, Function, and Feeding, Second Edition is authored by internationally recognized teachers and researchers in the field. This new edition reflects the resurgence of interest in the dentitions of non-mammalian vertebrates as experimental systems to help understand genetic changes in evolution of teeth and jaws.

Told through an examination of animal and plant life, this is an astonishing celebration of the evolution of life on earth, with a cast of characters drawn from the whole range of organisms that have ever lived on this planet. Attenborough's perceptive, dynamic approach to the evolution of millions of species of living organisms takes the reader on an unforgettable journey of discovery from the very first spark of life to the blue and green wonder we know today. To celebrate the 40th anniversary of the book's first publication, David Attenborough revisited Life on Earth, completely updating and adding to the original text, taking account of modern scientific discoveries from around the globe. This paperback edition also includes more than 60 full colour photographs, chosen by the author to help illustrate the book in a much greater way than was possible forty years ago. This updated edition provides a fitting tribute to an enduring wildlife classic, destined to enthral the generation who saw it when first published and bring it alive for a whole new generation.

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.

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.

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.

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.

This volume of Advances in Microbial Physiology continues the long tradition of topical and important reviews in microbiology

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.
