The mission of our department and curriculum is to educate students in the field of biology and within the context of a Kalamazoo College liberal arts education. Through our courses, research collaborations, and advising we help each of our students become an intrinsically motivated, self-directed learner who enjoys a biologist's keen awareness of the natural world. Specifically, we foster development of the following attributes in our biology majors: 1) knowledge of the diversity of living organisms and levels - from molecules to ecosystems - at which those organisms can be studied; 2) understanding of how organisms are affected by their evolutionary and developmental trajectories and how these are influenced by environmental contingency; 3) ability to discover new biological knowledge and then communicate it effectively to others; and 4) curiosity about and empathy toward our shared environment.
Requirements for the Major in Biology
Consonant with the experiential-learning focus of the K-Plan and motivated by the biology department mission, our emphasis on an empirical approach to biology creates an environment in which students develop a strong foundation in biology. We encourage our students to ask and seek answers to probing questions, interpret primary literature, design and perform experiments, and make original observations of biological phenomena. The developmental progression from introductory core courses through upper-level electives prepares students well for the challenges of carrying out their Senior Individualized Projects, presenting results of those projects at our annual Diebold Symposium, and then continuing their education or seeking employment after graduation.
Number of Units
- A minimum of nine biology courses (five required and four electives) and four cognates exclusive of lab credit, all at C- or better are required to complete a major in biology.
- Among biology electives, at least three must be at the 300 level or higher, one of which must be a lab course. Other than BIOL 112 and BIOL 123, students may not count 100-level courses towards units required for the major.
- Biology majors are encouraged to complete their Senior Individualized Project in biology.

Biology Courses for Nonmajors
All biology courses at the 100 level are open to nonmajors without prerequisite. Courses we offer for nonmajors have goals consistent with those for the biology curriculum focused on majors. To attain those goals, general education courses directed primarily at students not majoring in biology should help students:
- Appreciate, understand, and engage in the process of doing science.
- Evaluate validity of scientific communications. For example, our students should be able to read, understand, and evaluate any New York Times article, especially those in the Tuesday Science Times.
- Be comfortable with ambiguity and uncertainty.
- Learn that science is a fascinating human endeavor, applicable to everyday life.
BIOL101Biology: Stuff You Need to KnowIn this course for non-science majors, you will learn about contemporary biological issues that affect you - personally, as a citizen of human communities, and as a member of broader biotic communities. While exploring topics including evolution of antibiotic resistance, human reproduction, the human stress response, immunity to disease, and how our genes and surroundings influence who we become, you will learn how our understanding of these important issues develops over time, grow more accustomed to viewing yourself and your environment from the perspective of a biologist, and come to see biology as a fascinating human endeavor. Intended for non-majors.
BIOL102The Darwinian RevolutionEvolution is the unifying theory of biology but its origins and impact extend far beyond this scientific discipline. In this course we will explore the interplay between science, other disciplines, and society by examining the origins and development of evolutionary thought, with special emphasis on Darwin's theory of evolution by means of natural selection, and by discussing the ways in which Darwinism affects how we think about ourselves, our society, and the world in which we live. Topics for discussion include Social Darwinism, race and eugenics, human origins, creationism, and sociobiology. Intended for non-majors.
BIOL112Evolution and Genetics with LabAn introduction to principles of evolution and genetics. Includes a comprehensive overview of genetics from molecular, classical, and population perspectives, as well as in-depth treatment of evolutionary mechanisms, phylogenetic analysis, and the history of life on Earth. Laboratories include the purification and analysis of DNA, Drosophila and bacterial genetics, computer and class simulations of evolutionary processes, and bioinformatics.
BIOL115Environmental ScienceIn this course you will (1) build a basic understanding of the physical and natural systems that make up the biosphere on Earth (land, water, atmosphere, and life) stressing the dynamics of these interconnected systems; (2) develop a scientific understanding of the causes and consequences of several of the major environmental problems facing today's society; (3) acquire the tools to enable you to think critically about other current and future environmental challenges you will face as a member of contemporary society. One weekend field trip is required. Intended for non-majors and as an entry to the Environmental Studies Concentration.
BIOL123Form and Function with LabOrganism-level phylogeny, morphology, and physiology are the major subject areas of this course; organisms interacting with, and adapting or adjusting to, their environments is the underlying theme running through these subject areas. Through this course students will learn how the environment, biotic and abiotic, shapes the form (morphology) and function (physiology and behavior) of organisms over ecological and evolutionary time.
BIOL195Special Topic: Life Is LiquidThe human body is mostly water; the surface of our planet is mostly water; water shapes the Earth, fills our cells, controls our climate, nourishes our crops, limits biodiversity and human populations -- it even plays an important role in politics around the world. In "Life is Liquid" we will explore the role of water in life, all the way from the molecular foundations up to water's importance as a contested and often limiting natural resource (for this reason, this Biology course also counts towards the Environmental Studies concentration). Intended for non-majors.
BIOL200Research Apprenticeship in BiologyApprenticeships intended to provide opportunities for biology majors to become regularly involved in ongoing research projects with faculty, either with the same faculty member for a number of quarters or with different faculty in different quarters. A minimum of 50 hours of work is expected for each quarter. Three apprenticeships earn one full unit toward graduation.
