Majoring and Minoring

The biology curriculum at Lewis & Clark prepares students for the demands and expectations of biological inquiry in the 21st century. Introductory courses explore the breadth and integrative nature of modern biology through immersion in the process of scientific investigation and emphasis on the core concepts that unite different realms of biological inquiry. Advanced courses allow more detailed treatments of the questions, techniques, and intricacies of a diverse array of topics ranging in scale from molecules to ecosystems. With small class sizes that allow direct interaction with our research-active faculty, all of whom share a unified commitment to inquiry-based learning, students report high levels of satisfaction with their education. We are proud that many find future success within top graduate programs and medical schools across the country.

  • Beginning in the 2019-2020 academic year three new introductory courses will be offered for Biology majors. These will replace Biology 141, 151, and 200, which will no longer be taught.

These three core courses are:

  • BIO 110: Biological Investigations - a 4-credit, hands-on, lab-based, introduction to scientific investigation through project-based studies of biological phenomena.  
  • BIO 201: Biological Core Concepts - Systems - a 4-credit, lecture-based introduction to core principles that underlie all of biology, illustrated through evidence-driven examples centered on integrative organismal biology and organisms’ interactions with the biotic and physical environment.
  • BIO 202: Biological Core Concepts - Mechanisms - a 4-credit, lecture-based introduction to core principles that underlie all of biology, illustrated through evidence-driven examples centered on interactions among molecules and cells within organisms.

Biology majors also complete at least a year’s study of chemistry (two years are recommended) and at least one college-level course in calculus, computer programming, or statistics. Students complete the major by choosing, with the help of their faculty advisers, at least six courses in biology that best serve their individual interests. Most of the upper-division biology courses require student teams to carry out student-designed investigations.

Planning your four years of study in Biology


Biology does not offer a minor.  However, students who have taken the necessary prerequisites are welcome to enroll in any of the department’s courses.
