Likelihood models for inferring the evolution of geographic ranges on phylogenetic trees.
How have the geographic ranges of species and clades evolved through time? This is a fundamental question of historical biogeography, yet analytical methods for its investigation remain poorly developed. We describe how range evolution may be modeled as the stochastic outcome of dispersal, local extinction, and lineage divergence, and how the model can be used to infer various aspects of historical biogeography, such as ancestral ranges, the rate and direction of dispersal, etc. in a likelihood framework. The techniques have been implemented in software and are illustrated with reference to empirical examples.
