Research Abstract |
Origin of the universal statistics those have been found in fossil data, ecosystems, and theoretical models are studied by statistical physics approach. We first examined different theoretical models and found features relevant for the resulting statistics, especially the distribution of species lifespan. Based on those results, we next introduced a simple graph model and analyzed the behaviors of the model.
