Evolutionary Trait Divergence Between Sister Species and Other
Paired Lineages
Sean A. S. Anderson <seanas.anderson@mail.utoronto.ca>
Compares alternative models of continuous trait differentiation in sister species and other paired lineages. Alternative models include approximations of divergent selection, drift, and stabilizing selection, plus a variety of extensions to facilitate the testing of process-to-pattern hypotheses. Alternative processes are expected to leave unique signatures in the distribution of trait differentiation in datasets comprised of many species pairs. Users supply species pair trait data and divergence times. The fit of alternative models is compared in a likelihood framework.

Compares the fit of alternative models of continuous trait differentiation between sister species and other paired lineages. Differences in trait means between two lineages arise as they diverge from a common ancestor, and alternative processes of evolutionary divergence are expected to leave unique signatures in the distribution of trait differentiation in datasets comprised of many lineage pairs. Models include approximations of divergent selection, drift, and stabilizing selection. A variety of model extensions facilitate the testing of process-to-pattern hypotheses. Users supply trait data and divergence times for each lineage pair. The fit of alternative models is compared in a likelihood framework.

R (>= 2.4), deSolve (>= 1.5), ape, subplex
Contains a number of comparative phylogenetic methods,
mostly focussing on analysing diversification and character
evolution.  Contains implementations of BiSSE (Binary State
Speciation and Extinction; Maddison et al. 2007: Syst. Biol.
56: 701) and its unresolved tree extensions (FitzJohn et al.
2009: Syst. Biol. 58: 595), MuSSE (Multiple State Speciation
and Extinction), QuaSSE (Quantitative State Speciation and
Extinction; FitzJohn 2010: Syst. Biol. in press), and GeoSSE
(Geographic State Speciation and Extinction; Goldberg et al.
2010: Syst. Biol.). Other included methods include Markov
models of discrete and continuous trait evolution and constant
rate speciation and extinction.
