Performance of A Priori and A Posteriori Calibration Strategies in Divergence Time Estimation. [PDF]
Genome Biol Evol, 2020 Abstract Relaxed molecular clock methods allow the use of genomic data to estimate divergence times across the tree of life. This is most commonly achieved in Bayesian analyses where the molecular clock is calibrated a priori through the integration of fossil information.

Phylogeny and divergence time estimation of Io moths and relatives (Lepidoptera: Saturniidae: Automeris) [PDF]
PeerJThe saturniid moth genus Automeris includes 145 described species. Their geographic distribution ranges from the eastern half of North America to as far south as Peru. Automeris moths are cryptically colored, with forewings that resemble dead leaves, and

Molecular Phylogeny, Divergence Time Estimation, and Biogeography of Moelleriella (Clavicipitaceae, Hypocreales) with Taxonomic Insights [PDF]
BiologyThe Clavicipitaceae family, including saprobes and insect and myco-pathogens, are widely distributed in nature across various trophic regions, and play important roles in insect population control, plant interactions, and symbiotic evolution.

Bayesian Estimation of Divergence Times from Large Sequence Alignments [PDF]
Molecular Biology and Evolution, 2010 Bayesian estimation of divergence times from molecular sequences relies on sophisticated Markov chain Monte Carlo techniques, and Metropolis-Hastings (MH) samplers have been successfully used in that context. This approach involves heavy computational burdens that can hinder the analysis of large phylogenomic data sets.

The Implications of Incongruence between Gene Tree and Species Tree Topologies for Divergence Time Estimation. [PDF]
Syst Biol, 2022 Phylogenetic analyses are increasingly being performed with data sets that incorporate hundreds of loci. Due to incomplete lineage sorting, hybridization, and horizontal gene transfer, the gene trees for these loci may often have topologies that differ ...

What did the dove sing to Pope Gregory? Ancestral melody reconstruction in Gregorian chant using Bayesian phylogenetics. [PDF]
PLoS ONEAn attractive goal in the study of Gregorian chant melodies is reconstructing unobserved melodies as they may have been transmitted along their history, especially as early chant notation does not capture pitch exactly.

Estimating divergence times from DNA sequences [PDF]
Genetics, 2020 ABSTRACT The patterns of genetic variation within and among individuals and populations can be used to make inferences about the evolutionary forces that generated those patterns. Numerous population genetic approaches have been developed in order to infer evolutionary history.

Estimating Divergence Times in Large Phylogenetic Trees [PDF]
Systematic Biology, 2007 A new method, PATHd8, for estimating ultrametric trees from trees with edge (branch) lengths proportional to the number of substitutions is proposed. The method allows for an arbitrary number of reference nodes for time calibration, each defined either as absolute age, minimum age, or maximum age, and the tree need not be fully resolved.
