Phylogenies reveal new interpretation of speciation and the Red Queen

By Chris Venditti, Andrew Meade and Mark Pagel

Abstract

The Red Queen metaphor has species accumulating small changes to keep up with a continually changing environment, with speciation occurring at a constant rate. This constant-rate claim is now tested against four competing models, using 101 phylogenies of animal, plant and fungal taxa. The results provide a new interpretation of the Red Queen; a view linking speciation to rare stochastic events that cause reproductive isolation
