Abstract

A stochastic branching process model of phylogeny with niche space and interactions among species s considered. For an intermediate interaction range, the time series of diversity has long periods of stasis divided by periods of rapid increase. The concept of monophyletic size is introduced, and it is shown that the size distribution obeys Zipf's law.
