Haarautumisia

Haarautumisia, or haarautuminen (plural), is a Finnish term that refers to branching or bifurcation: the process by which a single line, structure, or system splits into two or more parts. The word derives from haara, "branch," with the suffix -utuminen indicating a process or result. In Finnish, the term is used across natural sciences and mathematics to describe both physical branching and abstract splitting.

In biology and botany, haarautuminen describes growth patterns in stems, roots, and vascular networks. Examples include dichotomous branching in some plants, ramification of tree crowns, and the branching of arteries or airways in animals.

In neuroscience, dendritic arborization and axonal branching describe how neurons extend processes to form networks.

In hydrology and geography, the term is used for river bifurcations or distributaries where a stream splits into separate channels.

In mathematics and probability, haarautuminen corresponds to bifurcation phenomena in dynamical systems and to branching processes, such as Galton–Watson processes, where one entity yields multiple descendants.

In computer science and software development, branching refers to creating separate development lines in version control or to branching structures in control-flow graphs.
