“Traits” are central units of biological analysis—but how should they be individuated, and relative to which ontogenetic frame of reference? In my new paper, I argue that answering this isn’t easy—and matters more than it seems. 📃👇 link.springer.com/article/10.1... #philsci #HPBio #evosky #evodevo
Screenshot of a journal article titled "Two ontogenetic challenges to trait individuation" by Alejandro Fábregas-Tejeda, published in Synthese (2025) 205:219.  The abstract reads: "Trait individuation is an epistemically indispensable and heuristically fruitful practice in biological science. However, important ontological issues transcend an epistemology-only reading of what trait individuation entails (e.g., adaptation and homology), prompting scholars to advance models and frameworks to grapple with this problem. Here, I articulate two challenges that arise when advancing theories and frameworks to tackle trait individuation: the synchronicity and the diachronicity challenges. The synchronicity challenge involves specifying the traits an organism has at a given moment in ontogeny, whereas the diachronicity challenge involves understanding the causal processes that drive trait individuation in development and tracing these units across time. To delve deeper, I introduce extant functionalist and structuralist perspectives on trait individuation and evaluate how they address both challenges. Overcoming these challenges is necessary for such accounts to fulfill their theoretical promise of individuating the traits that organisms have in an ontologically sound way."

The BBC’s The Great Philosophers series with Bryan Magee is some of the best television ever made. It’s brilliant - no bells & whistles, no flashy gimmicks to hide a lack of substance. Just two people talking and thinking carefully. It’s being re-run on BBC4, but it’s also available online.
