Relaxed phylogenetics and dating with confidence

You will see the panel that allows you to create sets of taxa.Once you have created a taxa set you will be able to add calibration information for its most recent common ancestor (MRCA) later on.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.This is done using the program BEAUti (this stands for Bayesian Evolutionary Analysis Utility).

These models open the gate to a new field of "relaxed phylogenetics." Here we introduce a new approach to performing relaxed phylogenetic analysis.

Press the small “plus” button at the bottom left of the panel. Rename it by double-clicking on the entry that appears (it will initially be called untitled1).

Call it ingroup (it will contain all taxa except the lemur, which will form the outgroup). Since we know that lemur is the outgroup, we will set select the checkbox in the Monophyletic? This will ensure that the ingroup is kept monophyletic during the course of the MCMC analysis.

W.; Phillips, Matthew J.; Rambaut, Andrew In phylogenetics, the unrooted model of phylogeny and the strict molecular clock model are two extremes of a continuum.

Despite their dominance in phylogenetic inference, it is evident that both are biologically unrealistic and that the real evolutionary process lies between these two extremes.
