Concept of phylogeny with selected examples from each of the major kingdoms. 2. EVOLUTION a. Ecological equivalents b. Concept of niche c. Natural (and artificial) selection d. Speciation 1. Charles Darwin 2. The fossil record 3. Evidence for evolution 3. FORM AND FUNCTION Basic problems of the living state. Each problem is presented as a common problem to living organisms. Evolution and natural selection are unifying themes throughout the course. Each topic will be developed from the unicellular through higher vertebrates and vascular plants. Topics 1 through 11 are presented in following format: a. Introduction to process. What is the function. Resources needed and waste products created. b. Examples are chosen to show relationship between form and function of organisms. Each topic is covered in a logical evolutionary sequence using examples from the taxa listed below. After covering these topics students are familiar with the anatomy, life cycle, and ecological niches and habitats of each group listed. Anatomy with relevant structure(s) from the following taxa: Fungi: ascomycetes and basidiomycetes Heterotrophic protist: rhizopida, euglenozoa, and ciliophora Sponge Cnidaria Platyhelminth Mollusk Annelid p. 2 of 6 1. a. b. c. d. 2. a. b. c. 3. a. b. c. d. 4.

Approximately 400 pages of assigned reading is required. Students complete written assignments requiring analysis of data and literature reviews to draw conclusions. Students complete thirty laboratory experiments designed to meet the objectives and scope of the course. Laboratory work employs live material and emphasizes experimentation and testing variables and presentation and interpretation of results. Students formulate hypotheses and evaluate their lab data in relation to these hypotheses in written lab reports. Students use computers to calculate and interpret data 9. ASSIGNMENTS: Bi-weekly lab reports requiring analysis of data collected in the lab. Help students develop an understanding of the scientific method and the ability to use appropriate models to solve problems. Term project requiring review of current literature and analysis of data. Examinations requiring analysis of information to promote use the scientific knowledge and skills necessary for active citizenship. 10.
