Biology

Biology is the scientific study of life and living organisms, encompassing their structure, function, growth, evolution, and interaction with the environment. This discipline is centred on observable phenomena and experimental inquiry, applying principles from chemistry, physics and mathematics to understand the molecular and systemic processes that sustain life. From the cellular mechanisms driving metabolism to the ecological dynamics shaping biodiversity, biology systematically investigates the complexities of life at all scales.

An ever-adapting discipline, modern biology is divided into various specialised fields, each focusing on distinct aspects of life. Molecular biology and biochemistry elucidate the roles of DNA, RNA, and proteins in heredity and cellular function. Genetics explores inheritance patterns and gene expression, using tools like CRISPR for precise genome editing. Physiology studies the mechanical, physical, and biochemical functions of organisms, while ecology examines how organisms interact with one another and their environments. Evolutionary biology provides the framework for understanding the diversification of life through natural selection and adaptation over geological timescales.
