Course learning outcomes
Students will be able to 1) Describe the four fundamental processes of evolution: mutation, migration (gene flow), genetic drift, and selection. 2) Predict the evolutionary response to selection on quantitative traits using the concept of heritability. 3) Interpret phylogenetic trees and use phylogenetic and other methods for inferring the history of biological evolution with genetic and morphological data. 4) Apply analytical methods covered in the course to questions related to population management, forensics, epidemiology, and adaptation. 5) describe why accepting the truth of biological evolution is not the issue compared to valuing "the principles of reasoning and educated discourse that now make belief in evolution obligatory" (Sam Harris, The Moral Landscape).
The expertise of your instructors is organismal biology whereas research that addresses the ultimate origins of life involves cosmology and biochemistry. If interested in such research, a Google search of abiogenesis provides a Wikipedia starting point for the history and recent advances into research on the origin of life. Intelligent Design is also not addressed in this course because it represents a sociological rather than scientific issue (e.g., Kitzmiller v. Dover Area School District).

Course grading policies
Formative assessments – 20% of your final grade
- These assessments are graded based only on you completing them. You are not graded on getting the correct answer(s). These are designed to help you identify which topics/content areas you are strong versus weak on so you can target areas that need work for your studying. And, formative assessments help us identify content areas to focus more or less time on.
- Examples of formative assessments are in-class discussions and problem sets, iClicker questions, online quizzes.
Summative assessments – 80% of your final grade
- These assessments are graded based on whether you get them correct. Summative assessments evaluate student learning at the end of an instructional unit.
- Summative assessments will come in the form of four exams scores. Each exam score will contribute 20% to your final grade.
iCLICKERS - iClickers are required for this class, and we will use them for formative assessments. Be sure you have purchased an iClicker at the bookstore, and bring them to every class session. Please register your clicker right away. You will need your NetID username and password to register. It is critical that you continue to use the SAME clicker every day, and it is a good idea to put your name on your clicker in case you lose them of confuse them with other identical-looking clickers. Formative assessments using iClicker questions will continue as quizzes administered via D2L. Please check the Quizzes tab in D2L.
