Self-organized Critical Model Of Biological Evolution

Condensed Matter 2015-06-25 v1 q-bio

Abstract

A punctuated equilibrium model of biological evolution with relative fitness between different species being the fundamental driving force of evolution is introduced. Mutation is modeled as a fitness updating cellular automaton process where the change in fitness after mutation follows a Gaussian distribution with mean x>0x>0 and standard deviation σ\sigma. Scaling behaviors are observed in our numerical simulation, indicating that the model is self-organized critical. Besides, the numerical experiment suggests that models with different xx and σ\sigma belong to the same universality class. PACS numbers: 87.10.+e, 05.40.+j
