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.

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.

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

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.

An imaginative natural history survey of the wide world of spirits, from whiskey and gin to grappa and moonshine In this follow-up book to A Natural History of Wine and A Natural History of Beer, authors Rob DeSalle and Ian Tattersall yet again use alcoholic beverages as a lens through which to gain a greater appreciation of natural history. This volume considers highly alcoholic spirits in the context of evolution, ecology, history, primatology, molecular biology, physiology, neurobiology, chemistry, and even astrophysics. With the help of illustrator Patricia Wynne, DeSalle and Tattersall address historical and cultural aspects and ingredients, the distillation process, and spirits and their effects. They also call on an international group of colleagues to contribute chapters on brandy, vodka, tequila, whiskies, gin, rum, eaux-de-vie, schnapps, baiju, grappa, ouzo, and cachaca. Covering beverages from across the globe and including descriptions of the experience of tasting each drink, this book offers an accessible and comprehensive exploration of the scientific dimensions of spirits.

Genome sequencing enables scientists to study genes over time and to test the genetic variability of any form of life, from bacteria to mammals. Thanks to advances in molecular genetics, scientists can now determine an animal's degree of inbreeding or compare genetic variation of a captive species to wild or natural populations. Mapping an organism's genetic makeup recasts such terms as biodiversity and species and enables the conservation of rare or threatened species, populations, and genes. By introducing a new paradigm for studying and preserving life at a variety of levels, genomics offers solutions to previously intractable problems in understanding the biology of complex organisms and creates new tools for preserving the patterns and processes of life on this planet. Featuring a number of high-profile researchers, this volume introduces the use of molecular genetics in conservation biology and provides a historical perspective on the opportunities and challenges presented by new technologies. It discusses zoo-, museum-, and herbarium-based biological collections, which have expanded over the past decade, and covers the promises and problems of genomic and reproductive technology. The collection concludes with the philosophical and legal issues of conservation genetics and their potential effects on public policy.

What evolutionary process could have resulted in the unique and amazing human brain? New research by neuroscientists, paleontologists, and others reveals startling answers. After several million years of jostling for ecological space, only one survivor from a host of hominid species remains standing: us. Human beings are extraordinary creatures, and it is the unprecedented human brain that makes them so. In this delightfully accessible book, the authors present the first full, step-by-step account of the evolution of the brain and nervous system. Tapping the very latest findings in evolutionary biology, neuroscience, and molecular biology, Rob DeSalle and Ian Tattersall explain how the cognitive gulf that separates us from all other living creatures could have occurred. They discuss the development and uniqueness of human consciousness, how human and nonhuman brains work, the roles of different nerve cells, the importance of memory and language in brain functions, and much more. Our brains, they conclude, are the product of a lengthy and supremely untidy history-an evolutionary process of many zigs and zags-that has accidentally resulted in a splendidly eccentric and creative product.

Ever since the recognition of the Neanderthals as an archaic human in the mid-nineteenth century, the fossilized bones of extinct humans have been used by paleoanthropologists to explore human origins. These bones told the story of how the earliest humans—bipedal apes, actually—first emerged in Africa some 6 to 7 million years ago. Starting about 2 million years ago, the bones revealed, as humans became anatomically and behaviorally more modern, they swept out of Africa in waves into Asia, Europe and finally the New World. Even as paleoanthropologists continued to make important discoveries—Mary Leakey’s Nutcracker Man in 1959, Don Johanson’s Lucy in 1974, and most recently Martin Pickford’s Millennium Man, to name just a few—experts in genetics were looking at the human species from a very different angle. In 1953 James Watson and Francis Crick first saw the double helix structure of DNA, the basic building block of all life. In the 1970s it was shown that humans share 98.7% of their genes with the great apes—that in fact genetically we are more closely related to chimpanzees than chimpanzees are to gorillas. And most recently the entire human genome has been mapped—we now know where each of the genes on the chromosomes that make up DNA is located on the double helix. In Human Origins: What Bones and Genomes Tell Us about Ourselves, two of the world’s foremost scientists, geneticist Rob DeSalle and paleoanthropologist Ian Tattersall, show how research into the human genome confirms what fossil bones have told us about human origins. This unprecedented integration of the fossil and genomic records provides the most complete understanding possible of humanity’s place in nature, its emergence from the rest of the living world, and the evolutionary processes that have molded human populations to be what they are today. Human Origins serves as a companion volume to the American Museum of Natural History’s new permanent exhibit, as well as standing alone as an accessible overview of recent insights into what it means to be human.

Race has provided the rationale and excuse for some of the worst atrocities in human history. Yet, according to many biologists, physical anthropologists, and geneticists, there is no valid scientific justification for the concept of race.
To be more precise, although there is clearly some physical basis for the variations that underlie perceptions of race, clear boundaries among "races" remain highly elusive from a purely biological standpoint. Differences among human populations that people intuitively view as "racial" are not only superficial but are also of astonishingly recent origin.
In this intriguing and highly accessible book, physical anthropologist Ian Tattersall and geneticist Rob DeSalle, both senior scholars from the American Museum of Natural History, explain what human races actually are--and are not--and place them within the wider perspective of natural diversity. They explain that the relative isolation of local populations of the newly evolved human species during the last Ice Age--when "Homo sapiens" was spreading across the world from an African point of origin--has now begun to reverse itself, as differentiated human populations come back into contact and interbreed. Indeed, the authors suggest that all of the variety seen outside of Africa seems to have both accumulated and started reintegrating within only the last 50,000 or 60,000 years--the blink of an eye, from an evolutionary perspective.
The overarching message of "Race? Debunking a Scientific Myth" is that scientifically speaking, there is nothing special about racial variation within the human species. These distinctions result from the working of entirely mundane evolutionary processes, such as those encountered in other organisms.
