(2003) Nuclear gene sequences provide evidence for the monophyly of australidelphian marsupials. Ewing G, Nicholls G, Rodrigo A (2004) Using temporally spaced sequences to simultaneously estimate migration rates, mutation rate and population sizes in measurably evolving populations.
In phylogenetics, the unrooted model of phylogeny and the strict molecular clock model are two extremes of a continuum.
The second step is to actually run BEAST using the input file that contains the data, model and settings.
1 The final step is to explore the output of BEAST in order to diagnose problems and to summarize the results.
The goal is to estimate the phylogeny as well as the rate of evolution on each lineage based on dates of divergence of their host species.
You will need the following software at your disposal: • BEAST - this package contains the BEAST program, BEAUti, Tree Annotator and other utility programs.We describe how it can be used to estimate phylogenies and divergence times in the face of uncertainty in evolutionary rates and calibration times.Our approach also provides a means for measuring the clocklikeness of datasets and comparing this measure between different genes and phylogenies.We find no significant rate autocorrelation among branches in three large datasets, suggesting that autocorrelated models are not necessarily suitable for these data.In addition, we place these datasets on the continuum of clocklikeness between a strict molecular clock and the alternative unrooted extreme.
