Biology is the scientific study of living systems, dealing with the physical and chemical composition, structure, behaviour, and evolution of living organisms. Biology is divided into a series of sub disciplines, according to the subject of study – including Zoology (the study of animals), Microbiology (the study of microorganisms), Botany (the study of plants), Genetics (the study of heredity). Like all Natural Scientists, biologists use a combination of observation, experimentation, and mathematical modelling to develop their understanding. Biology, and its related disciplines, are sometimes referred to as “Life Sciences”. A Masters in Biology (normally an MA or MSc), or one of its sub-disciplines, normally requires an academic background in the Life Sciences, to provide the necessary grounding in scientific principles. With a Masters degree in the subject, students can gain entry to a variety of fields, including medical research, conservation, consultancy, and teaching.
