Biological science is one of today's broadest and most important areas of scientific research. In addition to being an exciting and multifaceted discipline for students interested in the study of life, it's also an incredibly popular undergraduate major, conferring one of the largest numbers of degrees.

Earning an online biology degree prepares you to conduct research or tackle the rigors of medical, dental, optometry, or veterinary school; the first- and second-year curricula of most postgraduate institutions have a biological basis. This places biology graduates in high demand for both medical school and employment. Earning an online biology degree is a good first step toward pursuing work in both scientific and nonscientific fields.

Curriculum for an Online Bachelor's in Biology

Students pursuing a biology degree online complete coursework that is a rigorous combination of core areas (including math, chemistry, physics, and principles of biology), major requirements, and related electives. Some schools offer the above concentrations or different niche areas of expertise, but the following classes are ones you're likely to see in most programs:

  • Cell and molecular biology: This field unifies genetics, biochemistry, and biophysics to study cells, their components, and how they interact with living organisms. The ultimate goal is to apply this understanding in beneficial ways, such as correcting disease-causing gene mutations. This knowledge prepares you to work as a molecular biologist, cellular biologist, or laboratory technician.
  • Human physiology: This branch of physiology covers major organ systems, such as the endocrine, nervous, musculoskeletal, and respiratory systems, and how and why they function. This class is useful for students interested in working in fields related to health care, government research, and fitness.
  • Ecology: Ecology is the study of natural ecosystems, including the distributions of and interactions between organisms and how these organisms interact with their environments. Ecological principles are key to solving biological and medical problems, such as disease dynamics and biodiversity preservation. This course is especially pertinent to careers in the great outdoors, such as park naturalists, environmental consultants, or restoration ecologists.

How Long Does it Take to get an Online Bachelor's in Biology?

Most bachelor's degrees in biology require students to complete a minimum of 120 credits, which takes an average of four years. However, several factors affect the length of an online biology program. Many students take advantage of the flexibility and convenience provided by online programing, which allows students to study part-time or at a slower pace; students who go this route can take as many as six years to graduate. Alternatively, individually-paced, asynchronous coursework is great for learners with busy lifestyles or unique educational needs. Self-paced learning also gives you the opportunity to graduate faster.

Another teaching method utilizes cohort learning, where students take classes at set schedules with the rest of their class; this helps students who struggle with time management stay on track. Other factors that can reduce the length of your program include previously-earned college credits, which can be transferred to meet bachelor's degree requirements, and whether or not your program offers accelerated coursework, which can reduce the time investment needed to earn a degree.

To determine the quality of your online biology degree, be sure to check the program's website for accreditation information. Accreditation means a trustworthy authority has recognized a program's merit in terms of its curricula, faculty, student support services, facilities, and financing. You can find lists of schools that meet these criteria on various agencies' websites. However, it is also important to verify the the purpose and legitimacy of the accrediting agency.

Institutions of higher learning can receive two different types of accreditation: regional and national. While national accreditation recognizes particular types of schools (e.g., vocational or religiously-affiliated schools), regional accreditation evaluates institutions based on their geography. Most online schools boast regional accreditation, which is the most widely recognized and prestigious type. It's also worth checking for programmatic accreditation from specialized associations in the biological sciences industry, such as the American Society for Biochemistry and Molecular Biology or the American Institute of Biological Sciences. These are both nonprofit organizations with thousands of members dedicated to advancing biological research and education.

Next, check the accrediting agency's legitimacy by accessing the websites of the U.S. Department of Education (ED) or the Council for Higher Education Accreditation (CHEA). These impartial bodies award stamps of approval to accrediting agencies, ensuring that they are qualified to approve schools' methods and standards. You can find databases of accredited schools on the ED's and CHEA's websites.
