Abstract

Models have long been used for understanding changing diversification patterns over time. The rediscovery that models with very different rates through time can fit a phylogeny equally well has led to great concern about the use of these models. We share and add to these concerns: even with time heterogeneous models without these issues, the distribution of the data means that estimates will be very uncertain. However, we argue that congruence issues such as this also occur in models as basic as Brownian motion and coin flipping. Taxon-heterogeneous models such as many SSE models appear not to have this particular issue.
