Product Information

Biology: The Essentials epitomizes what the market has come to recognize as Mariëlle Hoefnagels’s distinct and student-friendly writing style. Mariëlle presents up-to-date information through What's the Point?, Why We Care, Burning Questions, Get the Picture, and Scientific Literacy features, which are pedagogical tools designed to demonstrate to readers that biology is everywhere. Survey the Landscape and Pull It Together concept maps illustrate the connections within each unit and chapter. Biology: The Essentials offers a broader and more conceptual introduction to biology, simplifying the more complex biological content to the essential elements that introductory students need.
