About the field of Developmental Biology: The general field of biology encompasses an extremely wide range of fields and specializations since all life can fall under the category of biology. Developmental biology frequently focuses on development from a molecular perspective that traces the development of an organism from a single cell. Consequently developmental biology is frequently linked to studies of cellular/molecular biology . Developmental biology is often closely linked to disease studies such as cancer biology due to the relationship that has been identified between errors in the development process and disease. Developmental biology research can focus on basic or applied methods, and can also involve overlap with a variety of related fields including: conservation biology , ecology , evolutionary biology , marine biology , microbiology/immunology , neurobiology , oral biology , structural biology , anatomy , anesthesiology , biochemistry , bioengineering , bioethics , biomedical sciences , biometrics or biostatistics , chemistry , clinical laboratory sciences , epidemiology , genetics , genetic counseling , health sciences , and human_development . Developmental 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 .
