biologistdefined

Biologistdefined is a term used to characterize definitions or criteria in biology that are proposed or endorsed primarily by biologists based on empirical evidence and standard methods within the discipline. It signals that such definitions reflect current biological knowledge and professional consensus rather than being dictated by external authorities, lay intuition, or legal regulations. The term is not widely standardized and appears mainly in discussions of scientific authority, classification, and boundary drawing.

In practice, biologistdefined criteria are invoked when defining concepts such as species, life, or cellular organization. For instance, the Biological Species Concept, which defines species by reproductive isolation, is often described by biologists as a biologically grounded criterion; discussions about whether to adopt this or alternative concepts may frame the Biological Species Concept as a biologistdefined standard. Similarly, taxonomic thresholds, developmental stages, or measurable phenotypic criteria can be described as biologistdefined when biologists furnish the operational definitions used in research and classification.

Critics argue that overemphasizing biologistdefined definitions can overlook ethical, legal, or socio-cultural dimensions and may reflect disciplinary biases. Supporters contend that biology-based definitions ensure consistency with empirical evidence and experimental practice.
