The impact of the rate prior on Bayesian estimation of divergence times with multiple Loci.
Bayesian methods provide a powerful way to estimate species divergence times by combining information from molecular sequences with information from the fossil record. With the explosive increase of genomic data, divergence ...
RelTime Rates Collapse to a Strict Clock When Estimating the Timeline of Animal Diversification.
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. ...
Bayesian estimation of nonsynonymous/synonymous rate ratios for pairwise sequence comparisons.
The nonsynonymous/synonymous rate ratio (ω = d(N)/d(S)) is an important measure of the mode and strength of natural selection acting on nonsynonymous mutations in protein-coding genes. The simplest such analysis is the ...
Comparison of different strategies for using fossil calibrations to generate the time prior in Bayesian molecular clock dating.
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 ...
Characterization of the uncertainty of divergence time estimation under relaxed molecular clock models using multiple loci.
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 ...
Geogenetic patterns in mouse lemurs (genus Microcebus) reveal the ghosts of Madagascar's forests past.
Phylogeographic analysis can be described as the study of the geological and climatological processes that have produced contemporary geographic distributions of populations and species. Here, we attempt to understand how ...
