selectionlike

Selectionlike is an adjective used across several disciplines to describe processes, outcomes, or systems that resemble natural selection in their selective dynamics but do not involve biological organisms. In a selectionlike process, variation arises, some variants achieve differential success, and those successful variants become more prevalent or propagate, albeit through non-biological media such as ideas, software, or cultural practices.

The concept is employed to analyze how non-biological systems converge toward favored solutions or patterns. It emphasizes the iterative generation of variants, the evaluation of their relative fitness or utility, and the propagation of successful traits through replication, transmission, or selection pressure within a given medium. While inspired by evolutionary thinking, selectionlike analyses avoid biological assumptions about genetic inheritance, reproduction, or environment.

In computational contexts, selectionlike dynamics are seen in evolutionary algorithms and optimization methods that use fitness-based selection to guide the search for optimal solutions. In linguistics and cultural studies, selectionlike explanations describe how certain linguistic forms, behaviors, or memes spread because they are more efficient, socially attractive, or better suited to a community’s practices, even though there is no genetic reproduction involved. In these settings, selectionlike processes help explain rapid changes, convergence, or the emergence of dominant variants.

Critiques of the concept warn that labeling a process as selectionlike can obscure other mechanisms, such as coordination, learning, or random drift. Proponents argue that the term provides a useful heuristic for recognizing common pressures that shape systems beyond biology.
