Sectionalism, in a biological context, refers to the specialization of different parts or regions of an organism or system to perform specific functions. Think of it like an assembly line where each station focuses on a particular task to increase efficiency. In multicellular organisms, sectionalism is evident in the differentiation of cells into tissues and organs, each with a distinct role.
Understanding sectionalism helps us grasp how complexity arises from the coordinated efforts of specialized components. From the tissues in your body to the different departments within a company, sectionalism is a key principle!
