Bayesian phylogeny
WebA chronogram is a dated phylogenetic tree whose branch lengths have been scaled to represent time. Such chronograms are computed based on available date estimates (e.g. from dated fossils), which provide absolute time constraints for one or more nodes of an input undated phylogeny, coupled with an appropriate underlying model for evolutionary … WebPrograms for Bayesian inference of phylogeny currently implement a unique and fixed suite of models. Consequently, users of these software packages are simultaneously forced to use a number of programs for a given study, while also lacking the freedom to explore models that have not been implemented by the developers of those programs.

WebFeb 6, 2024 · Bayesian phylogenetic analyses are popular for interpreting nucleotide sequence data, however for such studies one needs to specify a site model and associated substitution model. Often, the parameters of the site model is of no interest and an ad-hoc or additional likelihood based analysis is used to select a single site model. Results WebFeb 2, 2024 · To account for phylogenetic uncertainty in our results, we applied all the analyses of this paper to the tree from Porto et al. (2024) and on two other phylogenies from Nyakatura and Bininda-Emonds (2012) and from Perri et al. (2024).. Time calibration on the tree from Porto et al. (2024) was performed using the “chronopl” function in the ape …
