Phylomemetic Patterns in Science Evolution—The Rise and Fall of Scientific Fields

We worked with David Chavalarias on an automated method for the bottom-up reconstruction of the cognitive evolution of science modeled as lineage relationships between scientific fields. We refer to these dynamic structures as phylomemetic networks or phylomemies, by analogy with biological evolution; and we show that they exhibstrong regularities, with clearly identifiable phylomemetic patterns. Some structural properties of the scientific fields – in particular their density -, which are defined independently of the phylomemy reconstruction, are clearly correlated with their status and their fate in the phylomemy (like their age or their short term survival).

Within the framework of a quantitative epistemology, this approach raises the question of predictibility for science evolution, and sketches a prototypical life cycle of the scientific fields: an increase of their cohesion after their emergence, the renewal of their conceptual background through branching or merging events, before decaying when their density is getting too low.
