Resolving phylogenetic signal from noise when divergence is rapid: a new look at the old problem of echinoderm class relationships.

Abstract excerpt

Resolving evolutionary relationships in groups that underwent fast radiation in deep time is a problem for molecular phylogeny, as the scant phylogenetic signal that characterises short internal branches is generally swamped by more recent substitutions. We implement an approach, that maps how the support for rival phylogenies changes when analysing subsets of sites with either faster and more heterogeneous rates...
