Part of the Introduction to Biology: Ecology, Evolution, and Biodiversity Specialization.
In the biodiversity course we examine the incredible variety of life that inhabits this planet including microorganisms, plants, and animals. For each of the major groups we’ll learn about their characteristics, functions, and how they came into existence as well as some of the roles they play in the natural world, and how they’re relevant to people. We’ll also take a close look at us humans and consider what we know about our origins and what might become of us in the future.
Module 1. What is Life and How Did it Begin?
- Be familiar with the various definitions of species used by biologists.
- Be aware of the different theories for how life began.
