The amount of information that can be obtained by using molecular techniques in evolution, systematics and ecology has increased exponentially over the last ten years. The need for more rapid and efficient methods of data acquisition and analysis is growing accordingly. This manual presents some of the most important techniques for data acquisition developed over the last years. The choice and justification of data analysis techniques is also an important and critical aspect of modern phylogenetic and evolutionary analysis and so a considerable part of this volume addresses this important subject. The book is mainly written for students and researchers from evolutionary biology in search for methods to acquire data, but also from molecular biology who might be looking for information on how data are analyzed in an evolutionary context. To aid the user, information on web-located sites is included wherever possible. Approaches that will push the amount of information which systematics will gather in the

Invertebrate Zoology: A Tree of Life Approach is a comprehensive and authoritative textbook adopting an explicitly phylogenetic organization. Most of the classical anatomical and morphological work has not been changed - it established the foundation of Invertebrate Zoology. With the explosion of Next-Generation Sequencing approaches, there has been a sea-change in the recognized phylogenetic relationships among and between invertebrate lineages. In addition, the merger of evolutionary and developmental biology (evo-devo) has dramatically contributed to changes in the understanding of invertebrate biology. Synthesizing these three approaches (classical morphology, sequencing data, and evo-devo studies) offers students an entirely unique perspective of invertebrate diversity. Key Features One of the first textbooks to combine classical morphological approaches and newer evo-devo and Next-Generation Sequencing approaches to address Invertebrate Zoology Organized along taxonomic lines in accord with the latest understanding of invertebrate phylogeny Will provide background in basic systematic analysis useful within any study of biodiversity A wealth of ancillary materials for students and teachers, including downloadable figures, lecture slides, web links, and phylogenetic data matrices

Phylogenomics: A Primer, Second Edition is for advanced undergraduate and graduate biology students studying molecular biology, comparative biology, evolution, genomics, and biodiversity. This book explains the essential concepts underlying the storage and manipulation of genomics level data, construction of phylogenetic trees, population genetics, natural selection, the tree of life, DNA barcoding, and metagenomics. The inclusion of problem-solving exercises in each chapter provides students with a solid grasp of the important molecular and evolutionary questions facing modern biologists as well as the tools needed to answer them.

A star curator at the American Museum of Natural History widens the palette and shows how the physical, natural, and cultural context of color are inextricably tied to what we see right before our eyes. Is color a phenomenon of science or a thing of art? Over the years, color has dazzled, enhanced, and clarified the world we see, embraced through the experimental palettes of painting, the advent of the color photograph, Technicolor pictures, color printing, on and on, a vivid and vibrant celebrated continuum. These turns to represent reality in "living color" echo our evolutionary reliance on and indeed privileging of color as a complex and vital form of consumption, classification, and creation. It's everywhere we look, yet do we really know much of anything about it? Finding color in stars and light, examining the system of classification that determines survival through natural selection, studying the arrival of color in our universe and as a fulcrum for philosophy, DeSalle's brilliant A Natural History of Color establishes that an understanding of color on many different levels is at the heart of learning about nature, neurobiology, individualism, even a philosophy of existence. Color and a fine tuned understanding of it is vital to understanding ourselves and our consciousness.

The human species is very young, but in a short time it has acquired some striking, if biologically superficial, variations across the planet. As this book shows, however, none of those biological variations can be understood in terms of discrete races, which do not actually exist as definable entities. Starting with a consideration of evolution and the mechanisms of diversification in nature, this book moves to an examination of attitudes to human variation throughout history, showing that it was only with the advent of slavery that considerations of human variation became politicized. It then embarks on a consideration of how racial classifications have been applied to genomic studies, demonstrating how individualized genomics is a much more effective approach to clinical treatments. It also shows how racial stratification does nothing to help us understand the phenomenon of human variation, at either the genomic or physical levels.

Tackling one of the most difficult and delicate of the evolutionary questions, this challenging book summarizes the more recent results in phylogenetics and developmental biology that address the evolution of key innovations in metazoans. Divided into three sections, the first considers the phylogenetic issues involving this area of the tree of life and the elucidation of those relationships that continue to trouble taxonomists. The second section considers the developmental biology of metazoan evolution including the development of the nervous system, sensory organs, and physiological maturation. Part three focuses on the evolution of pattern and process in the Metazoa.

"The origin of multicellular animals is one of those difficult and delicate biological problems that have been pondered for centuries. This book summarizes recent results in phylogenetics and developmental biology that address the evolution of key innovations in metazoans. The first section covers phylogenetic issues. Focusing on nervous system and sensory organ development, the second section addresses prominent questions concerning the developmental biology of metazoan evolution. A third section discusses the evolution of pattern and process in the incredible forms of life that we call Metazoa and covers evolution of life histories and the evolution of biogeochemical aspects of metazoans. The book has over 40 illustrations and an up-to-date bibliography of over 500 references. Each chapter concludes with a set of questions for study and discussion."--

It is well established that all humans today, wherever they live, belong to one single species. Yet even many people who claim to abhor racism take for granted that human "races" have a biological reality. In Troublesome Science, Rob DeSalle and Ian Tattersall provide a lucid and forceful critique of how scientific tools have been misused to uphold misguided racial categorizations. DeSalle and Tattersall argue that taxonomy, the scientific classification of organisms, provides an antidote to the myth of race's biological basis. They explain how taxonomists do their science-how to identify a species and to understand the relationships among different species and the variants within them. DeSalle and Tattersall also detail the use of genetic data to trace human origins and look at how scientists have attempted to recognize discrete populations within Homo sapiens. Troublesome Science demonstrates conclusively that modern genetic tools, when applied correctly to the study of human variety, fail to find genuine differences. While the diversity that exists within our species is a real phenomenon, it nevertheless defeats any systematic attempt to recognize discrete units within it. The stark lines that humans insist on drawing between their own groups and others are nothing but a mixture of imagination and ideology. Troublesome Science is an important call for researchers, journalists, and citizens to cast aside the belief that race has a biological meaning, for the sake of social justice and sound science alike.
