Introduction
Analyses of character evolution are among the most important and widely-used applications of phylogentic trees. A wide range of methods have been introduced to conduct such analyses. Our tutorials are divided into two major types of analyses: (1) analyses of single character and (2) analyses for testing correlations among multiple characters.
I. Single Character Evolution: Ancestral Reconstruction, Phylogenetic Signal, Rates & Patterns of Evolution
Ancestral Reconstruction and Tests of Phylogenetic Signal with Discretely-Coded Traits Using Mesquite:
Basic ancestral reconstruction with parsimony & maximum likelihood in Mesquite: What did the ancestral Darwin's Finch eat?
Ancestral reconstruction and phylogenetic signal of discrete traits in Mesquite: Reconstructing Ecological Specialization in Adaptive Radiations of Caribbean Anolis lizards and Columbine Flowers
Testing Patterns of Evolution of Discretely-Coded Traits Using BayesTraits:
Testing for Asymetry & Irreversibility in a Binary Trait: Are Floral Anthocyanins are Lost and Gained at Different rates?
Ancestral Reconstruction and Tests of Phylogenetic Signal With Maximum Likelihood Analyses of Discretely- and Continuously-Coded Traits in R:
