Universal Ecology. Understanding Life from Cells to Societies
Ecology is fundamental to understand the phenomenon of life from cells to societies. The origin of life is the origin of an ecology; it is the origin of a biosphere and our way of being in the world. We argue that what unfolded from there can be understood only if we do away with the levels-of-organization paradigm and view from a different perspective: what unfolds for life is a recurrent process guided by the first principles underlying energy, matter, and information flows. The details of this dynamic and its manifestation in different phenomena—from cells to ecosystems and societies—form the core of the research I will undertake at the Wissenschaftskolleg and that will become a book on the subject. This book is foremost a synthesis of works I have done during the last 30 years and also a source of original research ideas. Among the former are the issues of general laws underlying the structure of ecological systems, manifesting in recurrent mathematical objects or relationships, such as scaling laws or invariant distributions characterizing dynamics, and accounting for observables such as the distribution of species richness, species abundances, genes in populations, and gene families in genomes. Among the latter are the fundamental role of neutrality and realized fitness symmetry, the fundamental role of stochasticity and birth and death dynamics, the role of key environmental factors such as temperature in affecting ecological patterns from cells to ecosystems, and the universal character of these effects. The most important new insights provided by the book arise from the blending of ecology, math, physics, economy, philosophy, and sociology that runs through it. Importantly, we mount an organized attack aimed at deconstructing the metaphysics of the level-of-organizations paradigm and propose a different epistemological stance. The end result is a radical philosophical view on how to interpret ecological dynamics, including the human phenomenon, society, and its relation to the rest of the natural world.Recommended Reading
