Evolution of Robustness in Growing Random Networks
Entropy, 2023 Networks are widely used to model the interaction between individual dynamic systems. In many instances, the total number of units and interaction coupling are not fixed in time, and instead constantly evolve.

Evolution of robustness in digital organisms [PDF]
Artificial Life, 2004 We study the evolution of robustness in digital organisms adapting to a high mutation rate. As genomes adjust to the harsh mutational environment, the mean effect of single Imitations decreases, up until the point where a sizable fraction (up to 30% in ...

Evolution of drift robustness in small populations [PDF]
Nature Communications, 2017 Genetic drift can reduce fitness in small populations by counteracting selection against deleterious mutations. Here, LaBar and Adami demonstrate through a mathematical model and simulations that small populations tend to evolve to drift-robust fitness ...

Evolution of Robust Developmental Neural Networks [PDF]
, 2004 We present the first evolved solutions to a computational task within the Neuronal Organism Evolution model (Norgev) of artificial neural network development. These networks display a remarkable robustness to external noise sources, and can regrow to functionality when severely damaged. In this framework, we evolved a doubling of network functionality (

Pangenome Evolution Reconciles Robustness and Instability of Rhizobial Symbiosis
mBio, 2022 Root nodulating rhizobia are nearly ubiquitous in soils and provide the critical service of nitrogen fixation to thousands of legume species, including staple crops.

Evolution under fluctuating environments explains observed robustness in metabolic networks. [PDF]
PLoS Computational Biology, 2010 A high level of robustness against gene deletion is observed in many organisms. However, it is still not clear which biochemical features underline this robustness and how these are acquired during evolution.

Does mutational robustness inhibit extinction by lethal mutagenesis in viral populations? [PDF]
PLoS Computational Biology, 2010 Lethal mutagenesis is a promising new antiviral therapy that kills a virus by raising its mutation rate. One potential shortcoming of lethal mutagenesis is that viruses may resist the treatment by evolving genomes with increased robustness to mutations ...

Revisiting robustness and evolvability: evolution in weighted genotype spaces. [PDF]
PLoS ONE, 2014 Robustness and evolvability are highly intertwined properties of biological systems. The relationship between these properties determines how biological systems are able to withstand mutations and show variation in response to them. Computational studies

Evolution of robustness and cellular stochasticity of gene expression. [PDF]
PLoS Biology, 2013 Gene expression varies widely in cells with the same genotype and environment. Predicting the patterns of stochastic cellular fluctuations remains an unsolved challenge.
