This text aims to establish biology as a dynamic discipline - not just a collection of facts - Life develops students' conceptual understanding of biological processes with impeccable scholarship, a smooth narrative, experimental contexts, spectacular art and effective pedagogy. In the streamlined new edition, the reader will find an enhanced art program - with new features that focus on the stages of key, experiments and methodology, and that further clarify complex processes. Also for this edition: a new chapter on cell signalling, expanded coverage of plant and animal diversity, and an expansive medial/supplements package.
