Modularity
Modularity is the degree to which a system can be decomposed into independently functioning components with well-defined interfaces, a design principle that dominates software engineering, biology, manufacturing, and cognitive science.
Overview
Modular components can be developed, tested, and replaced independently; interfaces constrain permitted interactions; and modules can be reused across different systems without modification. In software, this underlies object-oriented programming and microservices; in biology, protein domains, organs, and developmental genetic modules each evolve with relative independence because changes to one module need not disrupt others.
Why it matters
The modularity of biological development has critical implications for evolution — modular systems can vary in one part without cascading failures through the whole, making them far more evolvable than tightly integrated designs. In medicine, modular drug targeting at specific molecular pathways is essential to precision oncology and the advance of targeted cancer therapies.
