The sciences that deal with living organisms and life processes, including biology, biochemistry, genetics, and related fields. These disciplines study the structure, function, growth, origin, evolution, and distribution of living things.
Compound of Greek 'bios' (life) and Latin 'scientia' (knowledge). The term emerged in the mid-20th century as biological sciences became increasingly specialized and interdisciplinary, requiring a broader umbrella term to encompass the growing field.
