Ancestral character estimation under the threshold model from quantitative genetics
Evolutionary biology is a study of life's history on Earth. In researching this history, biologists are often interested in attempting to reconstruct phenotypes for the long extinct ancestors of living species. Various ...
Two new graphical methods for mapping trait evolution on phylogenies
Modern phylogenetic comparative biology uses data from the relationships between species (phylogeny) combined with comparative information for phenotypic traits to draw model?based statistical inferences about the evolutionary ...
Insights into the influence of priors in posterior mapping of discrete morphological characters: a case study in annonaceae
Background Posterior mapping is an increasingly popular hierarchical Bayesian based method used to infer character histories and reconstruct ancestral states at nodes of molecular phylogenies, notably of morphological ...
The significance of meristic changes in the flowers of Sapotaceae
Sapotaceae belongs to the heterogeneous order Ericales and exhibits extensive diversity in floral morphology. Although pentamery is widespread and probably the ancestral condition, some clades are extremely variable in ...
Underparameterized model of sequence evolution leads to bias in the estimation of diversification rates from molecular phylogenies.
Macroevolutionary inferences from molecular phylogenies are becoming increasingly common (see Harvey et al., 1996; Mooers and Heard, 1997; Pagel, 1999; Barraclough and Nee, 2001). Many methods in which phylogenies are ...
