Abstract： Bayesian tip dating is a recently developed method to estimate divergence times and evolutionary rates. It overcomes several drawbacks in traditional stepwise approach. However, it also requires more knowledge about statistics. This paper hierarchically explains the theory and computation in the Bayesian tip-dating approach, and divides the whole process into prior for the divergence times, prior for the evolutionary rates, model for the character changes and Markov chain Monte Carlo algorithm, which are key components in this method. The aim is to provide a general guidance for paleontologists in empirical data analyses.

Abstract： This paper provides an overview and a protocol of molecular clock dating using MrBayes. Two modern approaches, total-evidence dating and node dating, are demonstrated using a truncated dataset of Hymenoptera with molecular sequences and morphological characters. The similarity and difference of the two methods are compared and discussed. Besides, a non-clock analysis is performed on the same dataset to compare with the molecular clock dating analyses.
