Multiple topologies in biology and linguistics

Abstract

In this talk we present the multiple tree topologies approach. In the multiple topologies approach, regular MCMC phylogenetic inference is extended using a mixture models approach (Pagel & Meade 2004) in order to estimate two topologies at the same time (Pagel & Meade 2006). This method can identify different evolutionary histories that may be found in subsets of the dataset. We present the model in mathematical detail, as well as applications in biology and linguistics.
