Biology is a natural science that involves the study of living organisms with a focus on their structure, formation, growth, distribution, taxonomy and evolution. Biology is used in a variety of fields and industries, and as expected, numerous college majors involve the study of biology. If you have a passion for biological science and a desire to secure a career rooted in this subject, you may want to learn about the various degrees that involve biology.

Marine Biology

Just as the name suggests, marine biology is the study of life in oceans and seas. All animal and plant forms ranging from microscopic plankton to great white sharks concern the field. Several marine biology schools offer the major, and one of the more famous is the Scripps Institution of Oceanography in La Jolla, California. The institute offers over 45 undergraduate courses including a major in marine biology that can easily lead to completing the Bachelor of Science in marine biology. The Scripps Institution places an emphasis on contemporary environmental issues and teaches the accoutrements of marine biology with the goal to help future scientists understand earth-system evolutions, climate, dynamics and sustainability in order to help protect the oceans.

Forensic Science

Forensic scientists use biology to identify living organisms; they can examine dirt and plant matter clinging to dead bodies and determine where a body was located before it was dumped. They can also examine bite marks and tell what animal caused it. When students major in forensic science, they must take several biology classes. Some forensic science programs even offer a concentration in biology, such as the B.S. offered through San Jose State University. Their four-year biology road map includes a variety of biology classes that educate the top biological forensic scientists in the industry.


A zoology major focuses on the scientific study of the structure, behavior, physiology, classification and distribution of all animals. Wildlife biology is a science used by zoologists to help study animals and classify them according to their physiology and molecular makeup. Zoologists collect biological data and specimens for further analysis in order to help preserve species, prevent diseases and to store for future research. Some zoologists take veterinary courses in order to provide health care to sick or wounded animals. Many schools, including the University of Florida, offer courses in physiology and molecular biology of animals to students going after the zoology major and to those in degree programs with an emphasis on veterinary medicine.


If you want to go to medical school to become a doctor, you will need to declare a premed major in college. As doctors must be fluent in the physical and molecular makeup of the human anatomy, biology is a subject heavily focused on in the premed curriculum. Georgetown College offers a premed major that requires students to take a solid year of biology classes in their freshman year. Some of these classes include organismal diversity, general microbiology, pathenogenic bacteriology and immunology, vertebrate anatomy and embryology, genetics and molecular biology, cell biology and many other biological subjects.
