Proceedings of Evolution and Statistical Physics conference (pp. 165-185). Berlin / Heidelberg: Springer.http://hdl.handle.net/10092/592We describe some discrete structural properties of evolutionary trees generated under simple null models of speciation, such as the Yule model. These models have been used as priors in Bayesian approaches to phylogenetic analysis, and also to test hypotheses concerning the speciation process.enChaptersFields of Research::230000 Mathematical Sciences::239900 Other Mathematical Sciences::239901 Biological Mathematics
