A new paper on autocatalytic sets was just published in the journal Ecological Modelling. In this paper, co-authors Roberto Cazzolla Gatti, Wim Hordijk, and Stuart Kauffman argue that biodiversity can be considered a system of autocatalytic sets, and that this view offers a possible answer to the fundamental question of why so many species can coexist in the same ecosystem.
