The Evolutionary Emergence of Intrinsic Regeneration in Artificial Developing Organisms
Inspired upon the development of living systems, many models of artificial embryogeny are being proposed. These are usually aimed at the solution of some know limitations of evolutionary computation; among these scalability, flexibility and, more recently, fault-tolerance. This paper focuses on the latter, proposing an explanation of the intrinsic regenerative capabilities displayed by some mod...
متن کاملEmergence of Multicellular Organisms with Dynamic Differentiation and Spatial Pattern
The origin of multicellular organisms and the mechanism of development in cell societies are studied by choosing a model with intracellular biochemical dynamics allowing for oscillations, cell-cell interaction through diffusive chemicals on a two-dimensional grid, and state-dependent cell adhesion. Cells differentiate due to a dynamical instability, as described by our "isologous diversificatio...
متن کاملEmergence of Multi-Drug-Resistant Organisms (MDROs) Causing Fournier’s Gangrene
BACKGROUND Fournier's gangrene is an uncommon but often devastating infection. There are few contemporary data on the risk factors and evolving microbiologic trends including drug-resistant organisms implicated in these life-threatening infections. METHODS A retrospective study of Fournier's gangrene from 2006 to 2015 at a large academic hospital was conducted. Cases were identified using ICD...
متن کاملEmergence of proto-organisms from bistable stochastic differentiation and adhesion.
The rise of multicellularity in the early evolution of life represents a major challenge for evolutionary biology. Guidance for finding answers has emerged from disparate fields, from phylogenetics to modelling and synthetic biology, but little is known about the potential origins of multicellular aggregates before genetic programmes took full control of developmental processes. Such aggregates...
متن کاملInvestigating the Emergence of Phenotypic Plasticity in Evolving Digital Organisms
In the natural world, individual organisms can adapt as their environment changes. In most in silico evolution, however, individual organisms tend to consist of rigid solutions, with all adaptation occurring at the population level. If we are to use artificial evolving systems as a tool in understanding biology or in engineering robust and intelligent systems, however, they should be able to ge...
