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 …

With proliferation of molecular phylogenies and advances in statistical modeling,
phylogeneticists can now address macroevolutionary questions that had traditionally been …

The total-evidence approach to divergence time dating uses molecular and morphological
data from extant and fossil species to infer phylogenetic relationships, species divergence …

Systematic relationships of cervids have been controversial for decades. Despite new input
from molecular systematics, consensus could only be partially reached. The initial, gross …

Hagfish depart so much from other fishes anatomically that they were sometimes considered
not fully vertebrate. They may represent:(i) an anatomically primitive outgroup of vertebrates …

Knowledge of phylogenetic relationships among species is fundamental to understanding
basic patterns in evolution and underpins nearly all research programs in biology and …

To fully understand macroevolutionary patterns and processes, we need to include both
extant and extinct species in our models. This requires phylogenetic trees with both living …

Likelihood-based methods are commonplace in phylogenetic systematics. Although much
effort has been directed toward likelihood-based models for molecular data, comparatively …

Dated phylogenies of fossil taxa allow palaeobiologists to estimate the timing of major
divergences and placement of extinct lineages, and to test macroevolutionary hypotheses …

Estimating divergence times on phylogenies is critical in paleontological and neontological
studies. Chronostratigraphically-constrained fossils are the only direct evidence of absolute …
