Evolutionary patterns of thoroughbreds are estimated in terms of distribution of life-spans, avalanche size of extinction and lineage size. All of them show power-law distribution with exponent of )2.0, and show the characteristics of a particular evolutionary pattern called punctuated equilibrium.
We consider an individual-based model of evolution. Species emergence as segregation of the population on to discrete positions in a hyper-cubical genotype space. The model emphasises interaction between coexisting genotypes. Although the rate of the micro-dynamics, consisting of reproduction and ki
