About the field of Biology: A graduate degree in biology can take a number of forms. Many degrees are research oriented, and may either cover biology in a more general sense or look at specific aspects of the field. Because biology encompasses anything that falls under the title of the "study of life," it is understandably a broad and varied field. Some specialization areas might include: cancer , cellular/molecular , conservation , developmental , ecology , evolutionary , marine , microbiology/immunology , neurobiology , oral , or structural . Related fields include anatomy , anesthesiology , biochemistry , bioengineering , bioethics , biomedical sciences , biometrics or biostatistics , chemistry , clinical laboratory sciences , epidemiology , health sciences , and human_development . Biology can also provide a good foundation for those interested in becoming medical doctors or pursuing medical research . Some programs also tend to have a business application such as those in the biotechnology or medical informatics .
