Speciational view of macroevolution: are micro and macroevolution decoupled?
V. Schwammle, E. Brigatti
We introduce a simple computational model that, with a microscopic dynamics driven by natural selection and mutation alone, allows the description of true speciation events. A stat…
Evolution of polymorphism and sympatric speciation through competition in a unimodal distribution of resources
E. Brigatti, J. S. Sa' Martins, I. Roditi
A microscopic agent dynamical model for diploid age-structured populations is used to study evolution of polymorphism and sympatric speciation. The underlying ecology is represente…
Sharp gene pool transition in a population affected by phenotype-based selective hunting
E. Brigatti, J. S. Sa' Martins, I. Roditi
We use a microscopic model of population dynamics, a modified version of the well known Penna model, to study some aspects of microevolution. This research is motivated by recent r…
Scaling properties of the Penna model
E. Brigatti, J. S. Sa' Martins, I. Roditi
We investigate the scaling properties of the Penna model, which has become a popular tool for the study of population dynamics and evolutionary problems in recent years. We find th…
