Biology
(Interdepartmental Undergraduate Program)
Iowa State University is a major center for research and education in the biological sciences. With over 200 faculty in the life sciences, students have the opportunity to learn from some of the nation’s leaders in biological research and teaching and to participate in innovative, meaningful research projects that explore frontiers of biology. Few other universities have such a wealth of faculty expertise available to undergraduate students, making Iowa State’s Biology Program the logical choice for those who want to participate in a thriving academic community.
The faculties of the Department of Ecology, Evolution and Organismal Biology and the Department of Genetics, Development and Cell Biology jointly offer the undergraduate biology major. This high quality academic program has the flexibility to accommodate a range of career goals while taking advantage of the university’s strengths in science and technology. A bachelor’s degree in biology provides excellent preparation for graduate study in biological disciplines ranging from the molecular to the ecological levels, and for entrance into various professional schools, such as human medicine, physical therapy, or veterinary medicine. The 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. By working with our professional and faculty advisers, it is possible to design a unique program of study that will meet student needs and objectives.
Students with special interests and aptitudes should consider combining biology with a minor or a second major in another subject, such as chemistry, environmental studies, journalism, mathematics, music, statistics, or many other subjects offered by the university.
Courses offered at other locations
In addition to biological science courses taught on campus, students may take courses at various remote locations and arrange to have the credits count toward the advanced courses required in the biology major. Courses in field and aquatic biology are offered at the Iowa Lakeside Laboratory. Courses in marine biology can be taken at the Gulf Coast Research Laboratory in Mississippi. Iowa State University is a member of the Organization for Tropical Studies, and students may take courses at the organization’s field Station in Costa Rica. Courses taught at field Stations associated with other universities throughout the country may also be applied to the degree. Attending a summer field Station adds an important component to an undergraduate program of study.
Courses Offered at Iowa Lakeside Laboratory at Milford, Iowa
Iowa Lakeside Lab is an Iowa Regents facility located at Lake Okoboji in northwest Iowa where various summer courses in field and aquatic biology are offered. Any of the following courses taken at the lab are directly applicable to the degree program in Biology. See the Iowa Lakeside Laboratory entry elsewhere in the catalog for a full description of the courses.
Courses offered at Gulf Coast Research Laboratory
The Gulf Coast Research Laboratory is affiliated with the University of Southern Mississippi. Iowa State students may register for marine biology courses and transfer credit to their degree programs under the number BIOL 480 Studies in Marine Biology. Written permission of the Biology Program Director is required for this arrangement. Courses that are available each summer may be viewed at www.coms.usm.edu.
Courses offered at Summer Biological Field Stations
Courses taken at summer field Stations may be transferred to Iowa State University as credit in BIOL 481 Summer Field Studies. Such Stations are found throughout the country and often offer courses that emphasize the adaptation of plants and animals to unique environments. See www.biology.iastate.edu for links to field Stations in different biomes, e.g. marine/coastal, Great Lakes, taiga, deciduous forests, deserts, Rocky Mts.
Courses offered by the Organization for Tropical Studies
Iowa State students may register for courses in tropical biology taught in Costa Rica by the Organization for Tropical Studies. Credit is transferred to Iowa State as BIOL 482 Tropical Biology. For further information check www.ots.duke.edu or inquire in the Biology Program Office.
Undergraduate research. Students who have interest in biological research are encouraged to become involved in the research projects of faculty members on campus. Those doing so may receive credit for the experience in BIOL 490 Independent Study. Internship experiences are often available at other universities and at industrial or government laboratories. Students participating in such projects may receive internship credit in BIOL 494 Biology Internship. Making the effort to find a suitable research mentor and engaging in research work can be one of the most valuable experiences of an undergraduate education.
International experience. Because major discoveries in science often result from global efforts, biology majors are encouraged to include an international or study abroad component in their degree programs. This can be done by participating in international field trips originating from the ISU campus in BIOL 394 International Field Trips in Biology or similar courses in other departments. Many students choose to study abroad, attending a university in another country for up to a year as an exchange student. Minors in related disciplines or a foreign language can add an international emphasis to a degree in biology.
Supporting course requirements. Understanding the modern biological sciences requires an understanding of the physical and Mathematical sciences. Consequently, a minimum number of credits in general chemistry, organic chemistry, biochemistry, and physics are required. See the Biology Program Web Site for specific supporting science requirements.
The Math requirement is competency based. After demonstrating competency in algebra and trigonometry, biology majors must take: two semesters of calculus; or two semesters of Statistics; or one semester of calculus and one semester of Statistics chosen from a list of approved courses available on the Biology Program Web Site and in the Biology Program Office.
Students in the College of Liberal Arts and Sciences, must fulfill the foreign language and general education requirements listed elsewhere in this catalog for that college. Students in the College of Agriculture and Life Sciences must meet the general education requirements for that college as listed elsewhere in the catalog.
Given the important role of writing in the modern sciences, biology majors must demonstrate communication competency by earning a minimum of C in both ENGL 150 Critical Thinking and Communication and ENGL 250 Written, Oral, Visual, and Electronic Composition or equivalent composition courses and in one advanced writing course numbered ENGL 302 Business Communication through ENGL 316 Creative Writing--Playwriting, or JL MC 347 Science Communication.
Customizing a degree
The advantage of choosing a biology major is the flexibility it allows in customizing a program of study to individual goals. That said, the faculty recognizes that many students studying biology have common goals. Consequently, the faculty has developed specific recommendations for students interested in pursuing the following areas of study:
Teacher Licensure. Biology majors seeking licensure to teach biology in secondary schools must meet requirements of the Teacher Education Program as well as those of the Biology Program. In addition they must apply formally for admission to the teacher education program. See the section on Teacher Education for a list of licensure areas, degree requirements, and other information about this program.
Premedical and Prehealth Professions Studies. Biology majors who will go on to medical or health professional schools are urged to determine the entrance requirements for the institutions where they might study. A list of courses recommended for those who wish to pursue a pre-med curriculum is available in the Biology Program office.
Preveterinary Studies. Many students whose goal is to attend veterinary school choose Biology as their major. The requirements for entrance to the Iowa State Veterinary College are listed elsewhere in this bulletin and should be consulted as programs of study are planned.
Preparation for Graduate Studies. Students who are considering graduate school to further their education in a biological sciences should identify a faculty member who has similar interests. Faculty can mentor students as undergraduates providing a smooth transition to graduate school.
Minor
A minor in Biology is offered by the Biology Program. The minor requires 15 credits in Biology, and includes the completion of the specific courses listed below:
| BIOL 211 | Principles of Biology I | 3 |
| BIOL 211L | Principles of Biology Laboratory I | 1 |
| BIOL 212 | Principles of Biology II | 3 |
| BIOL 212L | Principles of Biology Laboratory II | 1 |
And 7 credits in biology courses numbered 300 or above. Nine (9) credits of the required courses must only apply to the minor. For more information, see the Biology Program Web Site, or contact the Biology and Genetics Student Services Office in 103 Bessey Hall.
Undergraduate Study
Biology majors, start their studies in the biological sciences by taking a unified biology core curriculum consisting of six integrated courses, four with labs. The first year provides a broad introduction to the nature of life.
| BIOL 211 | Principles of Biology I | 3 |
| BIOL 211L | Principles of Biology Laboratory I | 1 |
| BIOL 212 | Principles of Biology II | 3 |
| BIOL 212L | Principles of Biology Laboratory II | 1 |
During the first year, students also take BIOL 110 Introduction to Biology and BIOL 111 Opportunities in Biology, which are half semester courses designed to introduce the student to the discipline of biology and opportunities for careers in biology. The second year explores concepts in ecology in BIOL 312 Ecology and the principles of genetics in BIOL 313 Principles of Genetics and BIOL 313L Genetics Laboratory. The third year includes courses in cell and molecular biology (BIOL 314 Principles of Molecular Cell Biology) and evolutionary biology (BIOL 315 Biological Evolution). Biology majors must take an additional 21 credits of biological science at the 300 level or above from an approved list of courses. Of these, at least 9 credits must be taken as biology courses, and a minimum of two laboratory or field courses must also be included. Students may earn the B.S. degree in Biology from either the College of Liberal Arts and Sciences or from the College of Agriculture and Life Sciences. Contact the Biology Program Office for details regarding differences in general education and course requirements which are specific to these colleges.
Biology majors should carefully consider their selection of upper-level courses to allow them to emphasize one or more of the sub-disciplines of Biology relevant to their post-baccalaureate objectives. The Biology Program has identified areas of special interest for many disciplines within Biology, with supporting 300-, 400-, and 500-level courses, enabling majors to gain substantial experience in these areas prior to graduation. Faculty advisers with experience in these subject areas work with students to provide advice about preparing for a range of Biology-related professions. Consult the Biology Program advising staff for more information.
Most biology courses numbered 300 or above can be used to satisfy the additional credit requirement. Some courses taught in other departments can also be applied to the biology major; advanced students should consider including 500 level courses in their programs. Check the Biology Program’s web site for a complete listing of acceptable upper-level life science courses
Biology majors must demonstrate competency in their understanding of the biological sciences. Thus, grades of C- or better in all biological science courses applied to the major are required. Furthermore, in order to graduate, a student must have a cumulative average in the major of at least 2.00.
Graduate Study
Biology is an undergraduate major only. Persons interested in graduate study in the biological sciences should apply directly to one of the life science graduate programs at Iowa State University. Interdepartmental graduate offerings in Bioinformatics and Computational Biology; Ecology and Evolutionary Biology; Genetics; Molecular, Cellular and Developmental Biology; Neuroscience; Plant Physiology; Toxicology; Immunobiology; and Environmental Science are also available. (See Index.)
A non-thesis master’s degree in Interdisciplinary Graduate Studies (biological sciences) has been established particularly for those who wish to have a more diversified program of advanced study than that generally permitted by specific departments and programs.
