NEW! Now in full color! With its distinctive investigative approach to learning, this best-selling laboratory manual is now more engaging than ever, with full-color art and photos throughout. As always, the lab manual encourages students to participate in the process of science and develop creative and critical-reasoning skills. The Eighth Edition includes major revisions that reflect new molecular evidence and the current understanding of phylogenetic relationships for plants, invertebrates, protists, and fungi. The sequence of the lab topics has been reorganized to reflect the closer relationship of the fungi and animal kingdoms. A new lab topic, “Fungi,” has been added, providing expanded coverage of the major fungi groups. The “Protists” lab topic has been revised and expanded with additional examples of all the major clades. Both lab topics include suggestions and exercises for open-inquiry investigations. In the new edition, population genetics is covered in one lab topic with new problems and examples that connect ecology, evolution, and genetics.
