issued from digital libraries, and modeled as lineage relationships between scientific fields. We refer to these dynamic structures as <em>phylomemetic networks<\/em> or <em>phylomemies<\/em>, by analogy with biological evolution; and we show that they exhibit strong regularities, with clearly identifiable phylomemetic patterns. Some structural properties of the scientific fields &#8211; in particular their <em>density<\/em> -, 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 <em>quantitative epistemology<\/em>, 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.<\/p>\n<p><strong>Citation: <\/strong>Chavalarias D, Cointet J-P (2013) Phylomemetic Patterns in Science Evolution\u2014The Rise and Fall of Scientific Fields.
