Biology

Biology (from Greek: βίος, bio, “life”; and λόγος, logos, “knowledge”) is the study of life. It is a field of empirical science that examines the structure, function, growth, origin, evolution, and distribution of living things both past and present. It classifies and describes the various forms of organisms, how organisms function, how species come into existence, and the interactions they have with each other and with the natural environment. Biology includes a broad spectrum of fields that address phenomena related to living organisms (biological phenomena), including botany, zoology and physiology.
