This website contains a useful collection of lecture notes and lab descriptions from an intermediate Biology course at San Francisco State University (SFSU). The course covers the following main topics: Diversity of Life, Evolutionary Principles, Phylogenetic Inference, and Principles of Ecology. Some of the lectures are also available in portable document format (PDF), and the labs are nicely laid out with great images and hyperlinks. The course website is maintained by Professor Bob Patterson of the SFSU Biology department, and is supported by funding from the Center for the Enhancement of Teaching.
