We investigate heavy-tailed distributions for within-locus selection coefficients, specifically a double-exponential and a Student's t distribution. Using Markov Chain Monte Carlo methods on a set of coding sequences from 91 autosomal ge ...

By selecting a particular class of morphological characters, researchers may also bias the analysis in such a way that groups with certain characteristics cluster with others for reasons other than homology. For instance, if the set of characters were weighted toward those involved in carnivory, car ...
