Student Learning Outcomes
  1. Develop a vocabulary of biological terms, which will enable communication (reading, writing, and speaking) about evolution, natural selection and ecology.
  2. Explain the process of evolution by natural selection.
  3. Discuss speciation (modes, rates, types), and the necessary steps and conditions required for occurrence their relationship to biodiversity.
  4. Construct and score phylogenetic trees to determine parsimonious pathways.
  5. Determine expected Mendelian ratios, sex-determination.
  6. Recognize and discuss the roles of community members in the transfer of matter and energy through the ecosystem.
  7. Explain the structure of DNA and its role in heredity and evolution.
  8. Recognize and explain species interactions and their roles in population dynamics and natural selection.
  9. Apply the principles of the Scientific method to design and experimental design in addressing a question.
  10. Perform basic statistical operations (T-test, Chi-Square, Hardy-Weinberg, and ANOVA) in application to population genetics and ecology.
