DOI: 10.1002/ece3.4921
Abstract: Abstract Bayesian estimates of divergence times based on the molecular clock yield uncertainty of parameter estimates measured by the width of posterior distributions of node ages. For the relaxed molecular clock, previous works have reported… read more here.

Evolutionary history and divergence times of Odonata (dragonflies and damselflies) revealed through transcriptomics
Sign Up to like & getrecommendations! Published in 2021 at "iScience"
DOI: 10.1016/j.isci.2021.103324
Abstract: Summary Dragonflies and damselflies are among the earliest flying insects with extant representatives. However, unraveling details of their long evolutionary history, such as egg laying (oviposition) strategies, is impeded by unresolved phylogenetic relationships, particularly in… read more here.

DOI: 10.1016/j.ympev.2019.106646
Abstract: Incomplete lineage sorting (ILS) can lead to biased divergence time estimates. To explore if and how ILS has influenced the results of a recent study of worldwide phylogeny of three-spined sticklebacks (Gasterosteus aculeatus), we estimated… read more here.

DOI: 10.1093/sysbio/syab021
Abstract: Phylogenies are increasingly being used as a basis to provide insight into macroevolutionary history. Here, we use simulation experiments and empirical analyses to evaluate methods that use phylogenies as a basis to make estimates of… read more here.

DOI: 10.1093/sysbio/syad015
Abstract: Cross-species introgression can have significant impacts on phylogenomic reconstruction of species divergence events. Here, we used simulations to show how the presence of even a small amount of introgression can bias divergence time estimates when… read more here.

DOI: 10.1093/sysbio/syz015
Abstract: Discrete morphological data have been widely used to study species evolution, but the use of quantitative (or continuous) morphological characters is less common. Here, we implement a Bayesian method to estimate species divergence times using… read more here.

DOI: 10.1093/zoolinnean/zlz006
Abstract: The chiton genus Tonicia is composed of 12 species, 11 of which are found in the eastern Pacific, but the taxonomic status and geographical distribution of these species have long been controversial. In this study,… read more here.

Diversification dynamics of total-, stem-, and crown-groups are compatible with molecular clock estimates of divergence times

DOI: 10.1126/sciadv.abf2257
Abstract: A wide range of divergence times is supported by birth-death models under constant rates of speciation and extinction. Molecular evolutionary time scales are expected to predate the fossil evidence, but, particularly for major evolutionary radiations,… read more here.

DOI: 10.1186/s12862-017-0941-z
Abstract: BackgroundThe taxonomy of pines (genus Pinus) is widely accepted and a robust gene tree based on entire plastome sequences exists. However, there is a large discrepancy in estimated divergence times of major pine clades among… read more here.

Empirical and Bayesian approaches to fossil-only divergence times: A study across three reptile clades

DOI: 10.1371/journal.pone.0169885
Abstract: Estimating divergence times on phylogenies is critical in paleontological and neontological studies. Chronostratigraphically-constrained fossils are the only direct evidence of absolute timing of species divergence. Strict temporal calibration of fossil-only phylogenies provides minimum divergence estimates,… read more here.
