Biological Sciences

The Department of Biological Sciences offers three distinct four-year curricula that lead to the baccalaureate degree. These are the Bachelor of Science in Biology, the Bachelor of Science in Biomedical Science, and the Bachelor of Science in Biotechnology (Fall 2022 pending THECB approval). In addition, Pre-Health professional programs are offered which include Pre-Medicine, Pre-Dentistry, Pre-Physical Therapy, Pre-Pharmacy, and Pre-Veterinary Medicine. The curricula are designed to maximize career opportunities and to prepare students for various graduate and professional school programs.  The Department of Biological Sciences provides a broad range of courses and learning opportunities designed to prepare students for diverse careers. Particular attention is given to maintaining updated curricula to keep pace with the rapidly changing field of biology. Whenever possible we emphasize hands-on experience with the biological techniques and instrumentation used by biologists world-wide and encourage students to become involved in faculty initiated research experiences.

A Master of Science degree is also offered. For further information, see the graduate section of this catalog.

Important Information Regarding Health Professions Programs

The Pre-Medical/Pre-Dental, Pre-Physical Therapy, Pre-Pharmacy, and Pre-Veterinary Support Areas in Biomedical Science are designed to meet or exceed the entrance requirements for medical, dental, physical therapy, pharmacy, and veterinary medicine programs in Texas. Other health professions programs including, but not limited to Physician Assistant, Optometry, Chiropractic, Occupational Therapy, Podiatry, Radiology Technician, and Dental Hygiene can vary considerably in terms of entrance requirements. Students interested in such programs are encouraged to earn a BS in Biomedical Science by following the General Biomedical Science Support Area. By allowing greater flexibility in elective courses, the General Biomedical Science Support Area can be easily adjusted to meet the entrance requirements of these health professions programs.

A program in Pre-Veterinary Medicine is also offered through the Department of Animal Science and the Department of Wildlife and Natural Resources. Although the Pre-Veterinary programs offered through these departments and the Department of Biological Sciences each meet all the requirements for admission to the Texas colleges of veterinary medicine, a student is typically best suited for one program or the other. It is important that a student discuss with an advisor which program is best suited to his or her interests, skills, and goals.

It is important to know that health profession programs may change entrance requirements without notice. Therefore, it is the responsibility of the student to check these requirements and work closely with an advisor to ensure that all requirements are met. If all of the entrance requirements for a professional program have been met, it is sometimes possible for a student to matriculate to the professional program prior to completing a degree at Tarleton. In this case, a student might meet the requirements of a Bachelor of Science degree at Tarleton by

  1. fulfilling the “Degree Requirements” as stated in the Academic Information section of the catalog and
  2. transferring the necessary hours from an approved professional school to Tarleton for a minimum total of 120 hours.

An advanced course in the fundamentals of vertebrate physiology emphasizing physiologic mechanisms from a basic molecular/cellular level up to the level of organ systems, which include the nervous, endocrine, muscular, cardiovascular, respiratory, digestive and urinary systems. The basic physiologic mechanisms are presented in the context of human physiology, however, how selected animals are adapted to particular environments is addressed. Laboratory exercises involve the use of electronic instrumentation to measure physiologic responses non-invasively in human volunteers or in surgically prepared animals. Prerequisite: 12 hours of BIOL and one semester of organic chemistry with laboratory. Lab fee: $2.

BIOL 4462. Ichthyology. 4 Credit Hours (Lecture: 3 Hours, Lab: 3 Hours).

A study of the anatomy, behavior, ecology, evolution, taxonomy, and zoogeography of fishes. Field and laboratory work provide students with practical experience in collecting, identifying, and studying fishes. Emphasis will be placed on local fauna. Prerequisite: BIOL 1406 and BIOL 1407. Lab fee $2.
