About Biological Principles

About this course

Biological Principles is an active-learning class that will introduce you to basic principles of modern biology, including evolution, ecological relationships, biomacromolecules, bioenergetics, cell structure, and genetics. This course will help you develop critical scientific skills that include hypothesis testing, experimental design, data analysis and interpretation, and scientific communication. Class time will include a variety of team-based activities designed to clarify and apply new ideas by answering questions, drawing diagrams, analyzing primary literature, and explaining medical or ecological phenomena in the context of biological principles. We will spend class time on building your comprehension of the material you find the most difficult, based on pre-class assessments.

What’s the blue text?

This textbook is editorially agile to keep pace with the course as it develops. We craft content for readers carefully, and then seek reader feedback. If you see blue text while you read, that reflects text (or images) changed  in real time during the semester to help you better work with and learn the course material.
