This unit introduces learners to systematics and classification as well as the history and diversity of life on Earth. The core concepts of phylogeny, the history of life, and the defining features of the domains and kingdoms of organisms are discussed through examples. The diversity and importance of life are reinforced through media and special call-out features on sweetgrass and salmon to make connections between Western Science and Indigenous ways of knowing.
Unit 3 Course Learning Outcomes
By the end of this Unit, you will be able to:
- Explain our changing view of the evolutionary history of biological diversity;
- Classify living organisms;
- Understand and articulate the principles and processes of scientific inquiry; and
- Think critically about the principles of biology studied and communicate your thinking clearly and concisely in speaking and in writing.
