Resumo: Phylogenetic trees are systematic tools to describe relatedness among species and the temporal record of branching from common ancestors. In addition, the topology of nodes and branches of the tree encodes information about the process of speciation that originated those species. Unraveling this information is a major challenge in phylogenetics. In this talk I will show how phylogenetic trees can be computed in individual based models and show results for a particular model of speciation based on assortative mating.
I will show that tree unbalance represents a reliable measure of the number of genes involved in the speciation process. Adding information on geographic and abundance distributions permits the separation between sympatric and parapatric processes, allowing a partial reconstruction of the speciation history.
