The evolution of characters (measurements, observations) among
taxa (species, genes) can be studied both to infer history and
interpret processes of change.
History: Reconstruction of
ancestral states (Parsimony methods for molecular, categorical
and continuous data; Likelihood methods for categorical data;
Stochastic character mapping)
Processes of character evolution:
parameters and correlations (Estimating parameters of one
and two parameter models for categorical characters; Pagel's
1994 correlation test; Felsenstein's Independent Contrasts;
Pairwise comparisons tests of character correlation; Visualizations
to explore character correlations)
