BIO-150-20, Principles of Evolution
INSTRUCTOR: Paul Weldon
SCHEDULE/DAY/TIME: SEM/Saturday/12:00 - 2:45 PM, 02/02/2013-05/11/2013
The process of evolution underpins all of biology, from the origin of replicating molecules to the global distribution of plants, animals, and other organisms. This course introduces non-majors to the evidence for evolution and to its basic tenets. The course focuses primarily on modern evidence for evolution following arguments initially presented in Charles Darwin's "The Origin of Species." These include, first, a clarification of the processes and agents of natural selection. Examples of evolutionary phenomena to be examined include domestication by humans as a process analogous to changes induced in animals and plants by natural selection; the fossil record, where the appearance and extinction of major groups of organisms throughout Earth's history are described; homology, where structures, metabolic pathways, behavior, and other features are inherited from common ancestors; transitional forms, where organisms intermediate to more familiar species have been unearthed; convergence, where unrelated organisms display similar adaptations to similar environments; and biogeography, where the distribution of organisms via plate tectonics, oceanic dispersal, and other mechanisms will be examined. The last segment of the course will describe evidence for evolution derived from modern biochemical and molecular biological studies. Topics of practical significance to be covered include the emergence of antibiotic resistance by microorganisms, insecticide resistance by insects, and the evolution of social behavior.

METHODS OF INSTRUCTION: lecture, texts, handouts, films
GRADING/ASSIGNMENTS: The grade in this course will be based, in part, upon 3 exams (100 pts each), each covering the chapters and material as outlined below. The final exam is not cumulative. In addition, students will be required to submit two short reports (50 pts each) and present two oral reports (50 pts each). Details of the style of the short reports will be provided in a guidelines sheet; the oral report expectations will be described in class. The topics of all oral and written reports must be approved by the instructor in advance. Students should have confirmed proposed topics by requesting that the instructor sign off on a hardcopy of the proposal or grant approval by email . Total points = 500 pts. Grade scale -- A (91-100%), B (81-90%), C (71-80%), D (61-70%), F (< 61%).
