Abstract The Mkv evolutionary model, based on minor modifications to models of molecular evolution, is being increasingly used to infer phylogenies from discrete morphological data, often producing different results from parsimony. The critical difference between Mkv and parsimony is the assumption of a “common mechanism” in the Mkv model, with branch lengths determining that probability of change for all characters increases or decreases at the same tree branches by the same exponential factor… Expand
Molecular and morphological clocks for estimating evolutionary divergence times
TLDR
The findings suggest that node‐ and tip‐calibration approaches may be better suited for nodes with many taxa, and highlight the importance of evaluating the concordance of intrinsic time structure in morphological and molecular data before any dating analysis using combined datasets. Expand
Scalable total-evidence inference from molecular and continuous characters in a Bayesian framework
TLDR
This work implements, benchmark and validate popular phylogenetic models for the study of paleontological and neontological continuous trait data, incorporating these models into the BEAST2 platform and illustrating and advancing the paradigm of Bayesian, probabilistic total evidence. Expand
Mismatch of the morphology model is mostly unproblematic in total-evidence dating: insights from an extensive simulation study
TLDR
The results suggest that total-evidence dating might work even without a good understanding of morphological evolution and that study design should instead focus on an adequate sampling of all relevant fossils, even those with highly incomplete preservation. Expand
Detecting Mosaic Patterns in Macroevolutionary Disparity
TLDR
A comparative framework that identifies heterogeneity in evolutionary patterns across large data sets of continuous traits is introduced that can supplement existing comparative approaches by inferring the complex, integrated patterns that shape evolution across the body plan from disparate developmental, morphometric, and environmental sources of phenotypic data. Expand
Which morphological characters are influential in a Bayesian phylogenetic analysis? Examples from the earliest osteichthyans
TLDR
Methods to critically appraise character support for conflicting phylogenetic hypotheses, such as that used here, should form an important part of phylogenetic analyses. Expand
A Systematist's Guide to Estimating Bayesian Phylogenies From Morphological Data.

TLDR
This review aims to help systematics researchers understand the biological meaning of common models and assumptions in phylogenetic trees and discusses how researchers can use and understand Bayesian methods for phylogenetic estimation. Expand
Total-evidence phylogeny and divergence times of Vermilingua (Mammalia: Pilosa)
TLDR
The first total-evidence phylogenetic analysis of Vermilingua is performed and it is obtained that the extinct Neotamandua is an ancestor of the extant Myrmecophaga, not a sister taxon as in previous studies that did not incorporate the possibility of anagenetic evolution between fossil and living taxa. Expand
Exploring the impact of unstable terminals on branch support values in paleontological data
TLDR
The results suggest that increasing character sampling and using extended implied weighting decreases the impact of wildcard terminals, and provides insights for designing future research dealing with unstable terminals, a typical problem of paleontological data. Expand
Death is on Our Side: Paleontological Data Drastically Modify Phylogenetic Hypotheses.
TLDR
Predictive models are developed that demonstrate that the possession of distinctive character state combinations is the primary predictor of the degree of induced topological change, and that the relative impact of taxa can be predicted to some extent before any phylogenetic analysis. Expand
Detecting mosaic patterns in phenotypic disparity
TLDR
A new method for the identification of suites, or modules, of continuous traits that display shared patterns in evolutionary disparity across lineages using a greedy hill climbing approach that combines several different strategies to the unsupervised learning of classification and mixture models.

Among-character rate variation distributions in phylogenetic analysis of discrete morphological characters.
TLDR
It is argued that researchers should test and adopt the most appropriate model of rate variation for the data set in question, and that discrete characters are increasingly used in more sophisticated likelihood-based phylogenetic analyses, it is important that these studies be built on the mostappropriate and carefully selected underlying models of evolution. Expand
Uncertain-tree: discriminating among competing approaches to the phylogenetic analysis of phenotype data
TLDR
It is found that all methods struggle to correctly resolve deep clades within asymmetric trees, and when analysing small character matrices, the Bayesian Mk model is the most accurate method for estimating topology, but with lower resolution than other methods. Expand

TLDR
Several new avenues of research are opened by an explicitly model-based approach to phylogenetic analysis of discrete morphological data, including combined-data likelihood analyses (morphology + sequence data), likelihood ratio tests, and Bayesian analyses. Expand
Morphological phylogenetic analysis with inapplicable data
TLDR
This work presents a single-character algorithm for ancestral states reconstruction in datasets that have been coded using reductive coding and shows that, compared to traditional methods, this new method identifies different trees as “optimal”; as such, correcting for inapplicable data may significantly alter the outcome of tree searches.

Performance of maximum parsimony and likelihood phylogenetics when evolution is heterogeneous
TLDR
It is shown that maximum likelihood and BMCMC can become strongly biased and statistically inconsistent when the rates at which sequence sites evolve change non-identically over time. Expand
Weighted parsimony outperforms other methods of phylogenetic inference under models appropriate for morphology
One of the lasting controversies in phylogenetic inference is the degree to which specific evolutionary models should influence the choice of methods. Model‐based approaches to phylogenetic inferenceExpand
An improved method for determining codon variability in a gene and its application to the rate of fixation of mutations in evolution
TLDR
It is found that for 29 species of cytochrome c the data fit the assumption that there is a group of approximately 32 invariant codons and that the remainder compose two Poisson-distributed groups of size 65 and 16 codons, the latter smaller group fixing mutations at about 3.2 times the rate of the larger. Expand
Bayesian methods outperform parsimony but at the expense of precision in the estimation of phylogeny from discrete morphological data
TLDR
Using simulated morphological data, it is demonstrated that the Mk-model outperforms equal-weights parsimony in terms of topological accuracy, and implied-weights performs the most poorly. Expand
Difficulties in testing for covarion-like properties of sequences under the confounding influence of changing proportions of variable sites.
TLDR
Although COV and RAS models provide a great improvement in likelihood scores over a homogeneous model with these simulated data, reconstruction accuracy of tree building is low, suggesting caution when it is suspected that proportions of variable sites differ in different evolutionary lineages.

TLDR
Together, the two carnivore supertrees remain the only complete phylogenetic estimates for all extant species and the new supertree, like the old one, will form a key tool in helping us to further understand the biology of this charismatic group of carnivores. Expand
