Header and abstract page of an original research article in History and Philosophy of the Life Sciences (2026, volume 48, article 12) titled "Modeling versatility as the hallmark of model organisms," authored by Guido I. Prieto and Alejandro Fábregas-Tejeda. Abstract In recent years, discussions on the epistemology of model organism-based research have emerged in the philosophy of science. A key topic of discussion is how the epistemic insights gained from model organisms differ from those gained through other experimental organisms used in laboratory and field research. Here, we argue that model organisms are epistemically special due to their nature as ontogenetically changeable, standardized, and evolved material model carriers. These characteristics afford six important kinds of modeling versatility that biologists marshal in their investigations: (i) synchronic target versatility; (ii) synchronic scope versatility; (iii) diachronic target versatility; (iv) diachronic scope versatility; (v) manipulation versatility; and (vi) discovery versatility. In presenting these dimensions of modeling versatility, we also clarify key notions such as ‘representational target,’ ‘representational scope,’ and ‘representational power’ as these apply to modeling practices that involve model organisms.

It has been argued that what sets model organisms apart from other experimental 🐋🌱 is their high representational power. In our latest 📃, we argue otherwise: the hallmark of MOs lies in the dimensions of modeling versatility they afford to scientists 👇 link.springer.com/article/10.1... #philsci #HPS

Each dyad (a, b) moves through four discrete states over time, represented by coloured circles. The dyad remains in a given state for a certain duration, or "holding time", before transitioning to a new state according to state-specific transition probabilities, indicated by arrows showing all possible (non-zero) transitions.

We propose a framework to empirically study animal social relationships by modelling social network (SN) data as time-series—that is, without the need to aggregate them over time.
