Rate heterogeneity, ancestral character state reconstruction, and the evolution of limb morphology in Lerista (Scincidae, Squamata).
Rates of phenotypic evolution derive from numerous interrelated processes acting at varying spatial and temporal scales and frequently differ substantially among lineages. Although current models employed in reconstructing ancestral character states permit independent rates for distinct types of transition (forward and reverse transitions and transitions between different states), these rates a...
متن کاملWARACS: Wrappers to Automate the Reconstruction of Ancestral Character States1
PREMISE OF THE STUDY Reconstructions of ancestral character states are among the most widely used analyses for evaluating the morphological, cytological, or ecological evolution of an organismic lineage. The software application Mesquite remains the most popular application for such reconstructions among plant scientists, even though its support for automating complex analyses is limited. A sof...
متن کاملUncertainty in the reconstruction of ancestral character states and limitations on the use of phylogenetic comparative methods.
Phylogenetic approaches to the study of comparative data have a long history in the field of animal behaviour (e.g. Lorenz 1941; Greene & Burghardt 1978; Gittleman 1981). However, since the publication in 1991 of Brooks & McLennan’s Phylogeny, Ecology and Behavior and Harvey & Pagel’s The Comparative Method in Evolutionary Biology, there has been a huge increase in the use of phylogenetic metho...
متن کاملEvolutionary History of Assassin Bugs (Insecta: Hemiptera: Reduviidae): Insights from Divergence Dating and Ancestral State Reconstruction
Assassin bugs are one of the most successful clades of predatory animals based on their species numbers (∼6,800 spp.) and wide distribution in terrestrial ecosystems. Various novel prey capture strategies and remarkable prey specializations contribute to their appeal as a model to study evolutionary pathways involved in predation. Here, we reconstruct the most comprehensive reduviid phylogeny (...
متن کاملHistorian: accurate reconstruction of ancestral sequences and evolutionary rates
Motivation Reconstruction of ancestral sequence histories, and estimation of parameters like indel rates, are improved by using explicit evolutionary models and summing over uncertain alignments. The previous best tool for this purpose (according to simulation benchmarks) was ProtPal, but this tool was too slow for practical use. Results Historian combines an efficient reimplementation of the...
