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.

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.

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.

An imaginative natural history survey of the wide world of spirits, from whiskey and gin to grappa and moonshineIn 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 cachaça.  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.

A celebration of beer—its science, its history, and its impact on human culture  “Curatorial eminences Rob DeSalle and Ian Tattersall serve up a potent scientific brew. . . .  A marvellous paean to the pint, and to the researchers probing its depths.”—Barbara Kiser, Nature  “Forced to choose between this book and a pint of hazy IPA, I would be at a loss. Better to consume them at the same time—both will go down easily, and leave you in an improved condition.”—Bill McKibben  What can beer teach us about biology, history, and the natural world? From ancient Mesopotamian fermentation practices to the resurgent American craft brewery, Rob DeSalle and Ian Tattersall peruse the historical record and traverse the globe for engaging and often surprising stories about beer. They explain how we came to drink beer, what ingredients combine to give beers their distinctive flavors, how beer’s chemistry works at the molecular level, and how various societies have regulated the production and consumption of beer.  Drawing from such diverse subject areas as animal behavior, ecology, history, archaeology, chemistry, sociology, law, genetics, physiology, neurobiology, and more, DeSalle and Tattersall entertain and inform with    their engaging stories of beer throughout human history and the science behind it all. Readers are invited to grab a beer and explore the fascinating history of its creation.

The definitive story of cannabis, from its evolution and biological quirks to its role in human history  In this entertaining natural history, Rob DeSalle provides a glimpse into the biological world through the lens of the marijuana plant. A close relative of hops with a surprising place in the botanical tree of life, cannabis has a unique life cycle, has evolved pathways for over four hundred compounds, and makes one thousand or so different chemicals that are stored in its tissues—some of which are the basis of its famed psychoactive properties.  With his scientist’s perspective on this well-known and controversial plant, DeSalle considers taxonomy, systematics, evolution, human physiology and neurobiology, and cultural issues. He discusses the plant’s complicated reproductive strategies; considers ancient arthropod-cannabis associations from South Asia; and offers a nuanced cultural history that extends from the first evidence of smoking cannabis more than two thousand years ago to the current debates over legalization. Engaging and extensively researched, with illustrations by Patricia J. Wynne, this is a vital resource for cannabis enthusiasts and anyone curious about the science behind this infamous “weed.”

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.

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 FeaturesOne of the first textbooks to combine classical morphological approaches and newer evo-devo and Next-Generation Sequencing approaches to address Invertebrate ZoologyOrganized along taxonomic lines in accord with the latest understanding of invertebrate phylogenyWill provide background in basic systematic analysis useful within any study of biodiversityA wealth of ancillary materials for students and teachers, including downloadable figures, lecture slides, web links, and phylogenetic data matrices

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.

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.

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 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 next few years by using high throughput methods and access to genomics information are also discussed in the manual.In summary, this book is a comprehensive account of practical vs theoretical and modern vs future achievements of molecular systematics in evolutionary biology.
