Biology is the study of life. It contains such topics as
classifying the various forms of organisms, how species come into existence, and
the interactions they have with each other and with the natural environment.
Biology encompasses a broad spectrum of academic fields that are often viewed as
independent disciplines. However, together they address phenomena related to
living organisms (biological phenomena) over a wide range of disciplines, many
of which, for example, botany, zoology, and medicine are considered ancient
fields of study.
