Traits shaping trees: Detecting character-state dependent diversification.
Although traits are commonly portrayed as evolving along branches of phylogenetic trees, it is clear that many traits actually affect the shape of the tree by changing the probabilility that a lineage will speciate or go extinct. Recently developed likelihood and Bayesian methods now allow rigorous tests of character-state dependent diversification, and have revealed some surprising shifts from previous notions about directionality in trait evolution. I will discuss these empirical examples and the anticipated impact of these new approaches on the field of comparative methods.
