New to this Edition
Major additions to the sixth edition focus on evolutionary principles and taxonomy. Evolutionary concepts must be presented clearly and convincingly in biology courses. The changes made will help instructors accomplish that goal by providing more evidence of evolution, more examples to illustrate evolutionary principles, and more detail on evolutionary mechanisms. Recent, fast-paced changes in animal taxonomy require constant reevaluation of the presentation of evolutionary relationships between animal taxa. Because the taxonomy of many animal groups is unsettled, we have tried to take a conservative, yet up-to-date, position on taxonomic revisions.
Chapter 4, Evolution: An Historical Perspective, is reorganized and presents new information on the distinction between microevolution and macroevolution. The coverage of the evidence of macroevolution includes an expanded discussion of paleontology, a reorganized and expanded discussion of homology, an analogy from the perspectives of both comparative anatomy and molecular biology, and a new presentation of evidence from developmental biology. A new section on phylogeny and common descent caps this chapter.
Chapter 5, Evolution and Gene Frequencies, begins with an expanded presentation of populations and gene pools. The sections on sources of variation and gene flow are enhanced with more information and new examples.
Chapter 9, Multicellular and Tissue Levels of Organization, presents new information on the evolutionary relationships of the Porifera, Cnidaria, and Ctenophora.
Chapter 13, Annelida: The Metameric Body Form, provides an updated taxonomy of the Annelida, including the presentation of the oligochaetes and leeches as members of a single class Clitellata.
Chapters 14 and 15 include an extensive update on arthropod taxonomy. Arthropods are presented as a monophyletic group, and recent thinking regarding crustacean ancestry for the phylum is discussed. There is expanded coverage of the hemocoel and insect nutrition and digestion.
Chordate taxonomy in chapters 17-22 has been updated. Chapter 18 includes expanded discussion of the evolution of jaws and paired appendages and the fish-to-amphibian transition. Chapter 19 introduces more coverage of the early evolution of the Stegocephalia and Tetrapoda. Chapter 21 has expanded coverage of bird evolution.
To further explain and support evolutionary concepts, this new edition has a second set of themed boxed readings (in addition to "Wildlife Alerts?) entitled "Evolutionary Insights." These boxes provide detailed examples of principles covered in a chapter and provide insight into how evolutionary biology works. For example, Chapter 4 includes a reading on big-cat biogeography that illustrates how a variety of sources of evidence are used to paint a picture of the history of one group of animals. Chapter 5 has a reading on speciation of Darwin's finches that illustrates how and why speciation occurs. Other readings describe ideas regarding animal origins and the debates that occur among taxonomists who try to sort out evolutionary relationships within animal groups.
Instructor's can customize this text using our do-it-yourself website! The Primis Content Center features more than one million items, including this and hundreds of other best-selling McGraw-Hill textbooks, laboratories, case studies, and readings. These materials, along with others including your own notes, can be customized into a black and white, high resolution printed textbook or a full-color Primis eBook that saves your students 1/3 off bookstore prices. Log on to our website, register, and create your own complimentary copy.
Each chapter includes a list of appropriate internet topics with hyperlinks in the OLC.
Emphasis on basic concepts at the most accessible level for students with no science background.
Numerous learning aids such as critical thinking questions, key terms, summaries, and glossary.
Evolutionary concepts are highlighted as they occur on the page.
"Wildlife Alert" boxes increase student awareness of the need to preserve animal habitats and species.
This text features an evolutionary and ecological focus, believing that these perspectives captivate students and are fundamental to understanding the unifying principles of zoology and the remarkable diversity within the animal kingdom.
In response to reviewer suggestions and requests, several chapters that are often treated as optional in courses; can be found on the text's website, including:
The Chemical Basis of Animal Life / Energy and Enzymes: Life's Driving and Controlling Forces / How Animals Harvest Energy Stored In Nutrients / Embryology
