Bayesian Molecular Clock Dating Using Genome-Scale Datasets.
(2019)Bayesian methods for molecular clock dating of species divergences have been greatly developed during the past decade. Advantages of the methods include the use of relaxed-clock models to describe evolutionary rate variation ... -
Characterization of the uncertainty of divergence time estimation under relaxed molecular clock models using multiple loci.
(2015-03)Genetic sequence data provide information about the distances between species or branch lengths in a phylogeny, but not about the absolute divergence times or the evolutionary rates directly. Bayesian methods for dating ... -
Comparison of different strategies for using fossil calibrations to generate the time prior in Bayesian molecular clock dating.
(2017-09)Fossil calibrations are the utmost source of information for resolving the distances between molecular sequences into estimates of absolute times and absolute rates in molecular clock dating analysis. The quality of ... -
Dating Microbial Evolution with MCMCtree.
(2022)This protocol explains how to use the program MCMCtree to estimate divergence times in microbial phylogenies. The main advantage of MCMCtree is the implementation of an approximation to the molecular data likelihood that ... -
RelTime Rates Collapse to a Strict Clock When Estimating the Timeline of Animal Diversification.
(2017-05-01)Establishing an accurate timescale for the history of life is crucial to understand evolutionary processes. For this purpose, relaxed molecular clock models implemented in a Bayesian MCMC framework are generally used. ... -
Using Phylogenomic Data to Explore the Effects of Relaxed Clocks and Calibration Strategies on Divergence Time Estimation: Primates as a Test Case.
(2018-07-01)Primates have long been a test case for the development of phylogenetic methods for divergence time estimation. Despite a large number of studies, however, the timing of origination of crown Primates relative to the ...
