300 | 400 The biological sciences at Iowa State University are organized into 20 departments and programs. These can be grouped into the basic sciences, agricultural sciences, and veterinary sciences. Well over 200 faculty consider themselves life scientists and most teach courses at the undergraduate and graduate levels. Such a large faculty group provides many opportunities for students to learn from some of the national leaders in biological research and teaching and to participate in exciting, meaningful research projects that explore frontiers in the life sciences. Few other universities have such a wealth of faculty expertise available to undergraduate students. Biology is an interdepartmental undergraduate major. Students majoring in Biology are able to integrate knowledge from several life science disciplines into a coherent, broadly based undergraduate program of study. Students who wish to study specific areas of the basic biological sciences should declare majors in animal ecology, biochemistry, botany, entomology, genetics, microbiology, or zoology. Course requirements for these majors are listed elsewhere in this bulletin under the department’s name. Although requirements for biology and related majors differ significantly, the courses taken during the first two years are similar. In particular, all require freshman biology and chemistry, most require calculus and organic chemistry, and all require credits in general education courses. As a result and with proper planning, a student is able to transfer from one basic biological science major to another without serious consequences any time during the first two years. For detailed requirements, see the catalog entries under the particular majors. The biology major is well suited for those who plan to teach biology, who wish to enter government or industrial employment in health or environmental professions, or who prefer educational breadth as an end in itself. A bachelor’s degree in biology provides excellent preparation for graduate study in many biological disciplines and for entrance into various professional schools, such as human medicine, physical therapy, or veterinary medicine. Students with particular interests can combine biology with a minor or a second major in another area, such as chemistry, environmental studies, a foreign language, journalism, mathematics, or other majors offered by the university. Undergraduate Study A unified biology core serves the various majors in the life sciences. This core consists of six integrated courses with labs that explore the basic principles of the biological sciences. The first year (Biol 201, 202) provides a broad introduction to the nature of life. The second year (Biol 301, 302) provides an integrated foundation in the principles of genetics, cell biology, and elementary biochemistry. The third year (Biol 312, 303) provides an ecological and evolutionary perspective. A detailed description of the courses required in the biology major is available in 201 Bessey Hall or is available on the WWW at the site listed above. Biology majors take a minimum of 40 credits in the biological sciences, including the following courses: Biol 102, 201, 201L, 202, 202L, 301, 301L, 302, 302L, 303, and 312 plus 18 additional credits in approved life science courses numbered 300 or above. A partial listing of approved courses by department follows: Animal Ecology Biochemistry, Biophysics and
Molecular Biology Biomedical Sciences Botany Entomology Genetics Zoology Iowa Lakeside Lab Many courses from the departments of Agronomy, Animal
Science, Horticulture and Plant Pathology may also be applied to
the Biology major. The complete list of approved courses may be
obtained in 201 Bessey Hall or viewed on the WWW at www.biology.iastate.edu Courses beyond the core must be chosen from at least
two departments so that the student’s program of study reflects
breadth of preparation. Students are encouraged to participate in
research projects by taking Biol 490 (Independent Study) in order
to gain research experience prior to graduation. A grade of C–
or better is required in all biological science courses applied
to the major and the cumulative average in the major must be at
least a C. Supporting course requirements include: 16 credits
in chemistry to include two semesters of general chemistry with
labs and at least one semester of organic chemistry with lab; after
demonstrating competence in algebra and trigonometry, two semesters
of calculus or two semesters of statistics chosen from a list of
approved courses available in 201 Bessey Hall; and a two-semester
sequence in general physics. Because biology is a major in the College of Liberal
Arts and Sciences, students must fulfill the foreign language and
general education requirements listed in this bulletin for that
college. In addition to courses offered on campus, courses
in field and aquatic biology are offered at the Iowa Lakeside Laboratory.
Courses in marine biology are available at the Gulf Coast Research
Laboratory in Mississippi. Students may also attend summer biological
field stations elsewhere and transfer credits back. Biology majors seeking certification to teach biology
in secondary schools must meet requirements of the College of Education
as well as those of the biology program. In addition they must apply
formally for admission to the teacher education program. See Index,
Teacher Education Program, Teacher Licensure. The program offers a minor in biology which may be
earned by credit in Biol 201, 201L, 202, 202L, 301, and 6 credits
in courses numbered 300 or above from the list included here. A
minor or a double major in biology with a major in Animal Ecology,
Agricultural Biochemistry, Biochemistry, Biochemistry, Botany, Entomology,
Genetics, Microbiology, or Zoology is not permitted. Likewise, a
minor in another basic biological science with a major in biology
is not permitted. Graduate Study A non-thesis master’s degree in interdisciplinary
graduate studies (biological sciences) has been established particularly
for teachers who wish to broaden and update their formal training
in biology. Courses open for nonmajor graduate credit: 374, 403I. Courses Primarily for Undergraduate
