Course Description

Introduces fundamental biological concepts and theories about diversity, evolution, and ecology, specifically evolutionary relationship, transformation of energy and matter, information flow, and systems at a population level or above.

Course learning outcomes

1. Provide morphological, molecular and developmental evidence for the phylogenetic relationships among and between taxonomic groups illustrating the common ancestry of life.
2. Explain how evolutionary, developmental, and environmental processes influence the evolution of structures, functions, and behaviors that impact fitness.
3. Explain how evolutionary processes impact biodiversity.
4. Use mathematical models to describe how populations change through time in relation to biotic and abiotic factors.
5. Describe the interconnectedness of organisms and their environment at different temporal and spatial scales.
6. Describe how the structure and function of organisms influence ecosystems.
7. Construct models explaining flow of energy and cycling of matter in different ecosystems at human and geologic time scales.
