A methodological approach to biological research that employs controlled experiments to test hypotheses about living systems and their mechanisms.

Experimental Biology

Experimental biology represents the systematic application of the scientific method to understand living systems through controlled manipulation and observation. This fundamental approach has revolutionized our understanding of life processes across all scales, from molecular biology to ecosystem dynamics.

Core Principles

Experimental Design

Formulation of testable hypotheses
Identification of dependent and independent variables
Implementation of proper experimental controls
Statistical design considerations
reproducibility standards

Key Methodologies

Laboratory Techniques

Field Studies

Historical Development

The field emerged from the natural philosophy tradition but gained rigorous framework during the scientific revolution. Pioneering work by scientists like Claude Bernard established the foundations of modern experimental biology through systematic investigation of physiological processes.
