Ecology & Evolutionary Biology

An understanding of the origin and maintenance of diversity − from genomes to ecosystems − underlies all life sciences and is critical to the stewardship of life. Ecology and Evolutionary Biology offers courses in biological diversity, conservation biology, environmental biology, animal behaviour, physiological, population, and community ecology, global change biology, molecular evolution, and population and quantitative genetics. Concepts are taught using a broad array of approaches, including molecular studies, laboratory experiments, computer and mathematical modeling, and field studies. The department also offers opportunities for students to conduct research projects in the laboratory and the field.

First-Year Courses

  • BIO 120H1 – Adaptation and Biodiversity


Advice for First Year

  • The Ecology and Evolutionary Biology specialist and Genome Biology major require these courses in first year: BIO 120H1 – Adaptation and Biodiversity, BIO130H1 – Molecular and Cell Biology, introductory chemistry (CHM 135H1 - Chemistry: Physical Principles and CHM 136H1 - Introductory Organic Chemistry), and introductory math (MAT 135H1 and 136H1 – Calculus I and II).
  • The EEB major requires BIO120H1, BIO130H1, and introductory chemistry.
  • The Biodiversity and Conservation Biology major requires BIO120H1, BIO130H1, and introductory mathematics in first year.
  • The Environmental Biology major requires BIO120H1, introductory chemistry, introductory mathematics, and one of BIO130H1 or introductory physics; minor requires only BIO120H1 in first year.
