Human Biology

Human Biology is the study of both the natural and social sciences pertaining to Homo sapiens. It is a very popular subject to study at University, as it provides an expansive foundation and stepping stone for future careers. Many who study Human Biology can continue their education at a variety of different schools, but are not limited to graduate school, medical school, law school and business school.

Although Human Biology covers both the natural and the social sciences, its major focus is mainly on the natural sciences. This branch of human biology is called Life Sciences, which is another broad category which is comprised of fields which involve the scientific study of humans as living organisms. It looks at physiology, genetics as well as the microbiology involved within our systems. While life sciences remains the centerpiece of Human Biology, other interdisciplinary fields have become relevant due to new and emerging fields such as biotechnology. Thus, by studying Life Sciences, one can better understand the quality and standards of life from a biological stand point. Its applicability extends into many fields such as medicine and pharmaceuticals.
