โœฆ Synopsis

Data of a number of different types have been put forward as evidence for self-organized critical behavior in evolution. These include fossil data on extinction rates and taxon lifetimes, evidence of fractal structure in taxonomic trees, and simulation data from experiments on artificial life. Here we present a new and very simple model of species origination and extinction which, although not critical, reproduces all of these data well. We suggest therefore, that data of these kinds should not be taken as evidence of self-organized criticality.

Self-organized criticality (SOC) occurs in systems consisting of a substrate or medium which can be locally stressed to a critical state. When the critical threshold is exceeded, the stress is distributed to the neighborhood around the locale, which can lead to critical states in the neighboring loc

Over the last century, many bird species have been introduced into the Hawaiian islands. The data indicate a scenario in which island communities build up to a critical number of species, above which avalanches of extinction occur. Plotting the distribution of extinction event sizes approximates a p

A new stochastic lattice gas model of ant brood tending is formulated to examine the role played by repulsive ant-ant interactions in the even distribution of care among brood members. The deterministic limit of the model is known to be self-organized critical. Numerical simulations of the model sho
