Helping Students Make Connections Across Biology
Campbell BIOLOGY is the unsurpassed leader in introductory biology. The text’s hallmark values–accuracy, currency, and passion for teaching and learning–have made it the most successful college introductory biology book for eight consecutive editions.
Building on the Key Concepts chapter framework of previous editions, Campbell BIOLOGY, Ninth Edition helps students keep sight of the “big picture” by encouraging them to:
- Make connections across chapters in the text, from molecules to ecosystems, with new Make Connections Questions
- Make connections between classroom learning, research breakthroughs, and the real world with new Impact Figures
- Make connections to the overarching theme of evolution in every chapter with new Evolution sections
- Make connections at a higher cognitive level through new Summary of Key Concepts Questions and Write About a Theme Questions
- Make connections outside of class with MasteringBiology®, the most widely-used online assessment and tutorial program for biology
Each chapter is organized around a framework of three to six Key Concepts that provide the context for supporting details, helping students to distinguish the forest from the trees.
- The Key Concepts are presented at the beginning of the chapter to orient students to the main ideas of the chapter. The Overview and chapter opening question engage students and set the stage for the chapter content.
- Numbered Concept Heads remind students of the main ideas as they begin each section of the chapter and make it easy for instructors to assign selected sections.
- Concept Check Questions at the end of each section provide a hierarchical framework for self-assessment that builds students’ confidence and then challenges them to push the limits of their understanding with two types of critical thinking questions: What if? Questions, which ask students to apply what they’ve learned, and new Make Connections Questions, which ask students to relate material to what they learned in an earlier chapter.
- The end-of-chapter Summary of Key Concepts refocuses students on the main points, emphasizing the chapter’s organizational structure. Summary diagrams provide a visual review of the material and new Summary of Key Concepts Questions enable students to check their understanding of a key learning goal for each Key Concept.
The text engages students in scientific inquiry, revealing “how we know what we know” and helping students develop their critical thinking and inquiry skills.
- New Impact Figures motivate and inspire students by demonstrating the impact of biology research on their daily lives, the field of biology, and global problems. Each Impact Figure includes a discussion of Why It Matters, suggests articles for Further Reading, and concludes with a What if? or Make Connections Question.
- Inquiry Figures help students understand the experimental basis of biological knowledge and provide a model of how to think like a scientist:
- Each Inquiry Figure begins with a research question and then explores how researchers designed an experiment, interpreted their results, and drew conclusions.
- Each Inquiry Figure references the source article for the experiment, encouraging students to extend their learning by exploring the primary literature.
- Each Inquiry Figure concludes with a What if? Question that asks students to consider an alternative scenario. These questions can serve as discussion starters for active learning in lecture, discussion sections, or student study groups.
- Selected Inquiry Figures invite students to read and analyze the original research article in the supplement Inquiry in Action: Interpreting Scientific Papers.
- Research Method Figures illustrate important techniques in biology.
- Scientific Inquiry Questions at the end of each chapter give students more opportunities to practice critical thinking by developing hypotheses, designing experiments, and analyzing real research data.
- Eight interviews with renowned researchers inspire students and show them the human side of science. The new Ninth Edition interviews feature Susan Solomon, National Oceanic and Atmospheric Administration, Boulder, Colorado; Bonnie Bassler, Princeton University; Joan Steitz, Yale University; Geerat J. Vermeij, University of California, Davis; W. Ford Doolittle, Dalhousie University, Canada; Luis Herrera-Estrella, National Polytechnic Institute, Mexico; Baldomero M. Olivera, University of Utah; and Camille Parmesan, University of Texas, Austin.
Carefully crafted figures help visual learners understand complex structures and processes and organize material into a clear hierarchy of ideas.
- New Visual Organizers highlight the hierarchy of information in multipart figures to help students understand and study the material.
- Exploring Figures help students access information efficiently by integrating text and visuals.
- Guided Tour diagrams walk students through a figure like an instructor would, pointing out key structures, functions, and steps of processes.
- In selected figures, a three-dimensional art style helps students visualize biological structures.
- Figure legend questions prompt students to delve into a figure’s content and assess their understanding.

This section provides just a few highlights of new content and organizational improvements in Campbell BIOLOGY, Ninth Edition.
Chapter 1 Introduction: Themes in the Study of Life
We have added a separate new theme on energy flow while retaining a theme on environmental interactions. Concept 1.3, on the scientific method, has been reframed to more accurately reflect the scientific process, with a focus on observations and hypotheses. A new Concept 1.4 discusses the value of technology to society while emphasizing the cooperative nature of science and the value of diversity among scientists.
Unit One The Chemistry of Life
For this edition, the basic chemistry is enlivened by new content connecting it to evolution, ecology, and other areas of biology. Examples of new material include omega-3 fatty acids, the isomeric forms of methamphetamine, arsenic contamination of groundwater, and the basis of mad cow disease. The burgeoning importance of nucleic acids throughout biology has prompted us to expand our coverage of DNA and RNA structures in this first unit. In fact, a general aim for the first two units is to infuse the chapters with more detail about nucleic acids, genes, and related topics. Another enhancement, in this and the next two units, is the inclusion of more computer models of important proteins in contexts where they support students’ understanding of molecular function.
Unit Two The CellFor Chapter 6, we developed an Exploring Figure on microscopy, which includes new types of microscopy, and we added micrographs of various cell types to the Exploring Figure on eukaryotic cells. We also expanded our description of chromosome composition, with the goal of preempting some common student misconceptions about chromosomes and DNA. New connections to evolution include an introduction to the endosymbiont theory in Chapter 6 and some interesting evolutionary adaptations of cell membranes in Chapter 7. We’ve added a new section to Chapter 8 on the evolution of enzymes with new functions, which not only strengthens enzyme coverage but also provides an early introduction to the concept that mutations contribute to molecular evolution. In Chapter 9, we simplified the glycolysis figure and emphasized pyruvate oxidation as a separate step to help students focus on the main ideas. In keeping with our increased focus on global issues in the Ninth Edition, Chapter 10 has an Impact Figure on biofuels and a discussion of the possible effect of climate change on the distribution of C3 and C4 plants. In Chapter 11, we have added an Impact Figure to highlight the importance and medical relevance of G protein-coupled receptors.
Unit Three Genetics
In Chapters 13–17, we have added material to stimulate student interest—for example, a new Impact Figure on genetic testing for disease-associated mutations. As done throughout the Ninth Edition, we ask students to make connections between chapters so that they avoid the trap of compartmentalizing the information in each chapter. For instance, Chapter 15 discusses the Philadelphia chromosome associated with chronic myelogenous leukemia and asks students to connect this information to what they learned about signaling in the cell cycle in Chapter 12. Also, we encourage students to connect what they learn about DNA replication and chromosome structure in Chapter 16 to the material on chromosome behavior during the cell cycle in Chapter 12. Chapter 16 has a new figure showing a current 3-D model of the DNA replication complex, with the lagging strand looping back through it.
Chapters 18–21 are extensively updated, with the changes dominated by new genomic sequence data and discoveries about the regulation of gene expression. (The introduction to genes, genomes, and gene expression in Units One and Two should help prepare students for these revisions.) Chapter 18 includes a new section on nuclear architecture, which describes the organization of chromatin in the nucleus in relation to gene expression. The roles of various types of RNA molecules in regulation also receive special attention. In the section on cancer, we describe how technical advances can contribute to personalized cancer treatments based on the molecular characteristics of an individual's tumor. Chapter 19 discusses the 2009 H1N1 flu pandemic. Chapter 20 includes advances in techniques for DNA sequencing and for obtaining induced pluripotent stem (iPS) cells. Finally, the heavily revised Chapter 21 describes what has been learned from the sequencing of many genomes, including those of a number of human individuals.
Unit Four Mechanisms of Evolution
For this edition, we have continued to bolster our presentation of the vast evidence for evolution by adding new examples and figures that illustrate key conceptual points throughout the unit. For example, Chapter 22 now presents research data on adaptive evolution in soapberry bugs, fossil findings that shed light on the origins of cetaceans, and an Impact Figure on the rise of methicillin-resistant Staphylococcus aureus. Chapter 23 examines gene flow and adaptation in songbird populations. Chapter 24 incorporates several new examples of speciation research, including reproductive isolation in mosquitofish, speciation in shrimp, and hybridization of bear species. Other changes strengthen the storyline of the unit, ensuring that the chapters flow smoothly and build to a clear overall picture of what evolution is and how it works. For instance, new connections between Chapters 24 and 25 illustrate how differences in speciation and extinction rates shape the broad patterns in the history of life. We’ve also added earlier and more discussion of “tree thinking,” the interpretation and application of phylogenetic trees, beginning in Chapter 22.
Unit Five The Evolutionary History of Biological Diversity
One of our goals for the diversity unit was to expand the coverage of the scientific evidence underlying the evolutionary story told in the chapters. So, for example, Chapter 27 now presents new findings on the evolutionary origin of bacterial flagella. In keeping with our increased emphasis on big-picture “tree thinking,” we’ve added an “evogram” on tetrapod evolution in Chapter 34. (An evogram is a diagram illustrating the multiple lines of evidence that support the hypothesis shown in an evolutionary tree.) In addition, to help engage students, we’ve included new applications and woven more ecological information into our discussions of groups of organisms. Examples include new material on global growth of photosynthetic protists (Chapter 28), endangered molluscs (Chapter 33), and the impact of a pathogenic chytrid fungus on amphibian population declines (Chapters 31 and 34).
Unit Six Plant Form and Function
Plant biology is in a transitional phase; some professors prefer strong coverage of classical botany while others seek more in-depth coverage of the molecular biology of plants. In developing the Ninth Edition, we have continued to balance the old and the new to provide students with a basic understanding of plant anatomy and function while highlighting dynamic areas of plant research and the many important connections between plants and other organisms. One major revision goal was to provide more explicit discussion of the evolutionary aspects of plant biology, such as the coevolution of insects and animal pollinators (Chapter 38). Updates include new findings in plant development in Concept 35.5 and new material on the dynamism of plant architecture as it relates to resource acquisition in Chapter 36.
Unit Seven Animal Form and Function
In revising this unit, we strove to introduce physiological systems through a comparative approach that underscores how adaptations are linked to shared physiological challenges. In particular, we have highlighted the interrelationship of the endocrine and nervous systems at multiple points in the unit, helping students appreciate how these two forms of communication link tissues, organs, and individuals. Other revisions aim to keep students focused on fundamental concepts amid the details of complex systems. For example, many figures have been reconceived to emphasize key information, including new figures comparing single and double circulation (Chapter 42) and examining the function of antigen receptors (Chapter 43), as well as new Exploring Figures on the vertebrate kidney (Chapter 44) and the structure and function of the eye (Chapter 50). Chapter 43 has been significantly revised to support students’ conceptual understanding of basic immunological responses and the key cellular players. Throughout the unit, new state-of-the-art images and material on current and compelling topics—such as circadian rhythms (Chapter 40), novel strains of influenza (Chapter 43), the effects of climate change on animal reproductive cycles (Chapter 46), and advances in understanding brain plasticity and function (Chapter 49)—will help engage students and encourage them to make connections beyond the text.
Unit Eight Ecology
Our revision was informed by the fact that biologists are increasingly asked to apply their knowledge to help solve global problems, such as climate change, that already are profoundly affecting life on Earth. As part of our increased emphasis on global ecology in this edition, we have made significant changes to Unit Eight’s organization and content. The organizational changes begin with the introductory chapter of the unit (Chapter 52), which includes a new Key Concept 52.1: “Earth’s climate varies by latitude and season and is changing rapidly.” Introducing the global nature of climate and its effects on life at the beginning of the chapter provides a logical foundation for the rest of the material. New content in Chapters 53 and 54 highlights factors that limit population growth, the ecological importance of disease, positive interactions among organisms, and biodiversity. Chapter 55 now explores restoration ecology together with ecosystem ecology because successful restoration efforts depend on understanding ecosystem structure and function. Finally, the new title of the unit’s capstone, Chapter 56, reflects its emphasis on the combined importance of conservation and our changing Earth: “Conservation Biology and Global Change.” Several new Impact Figures in the unit show students how ecologists apply biological knowledge and ecological theory at all scales to understand and solve problems in the world around them.
