Fossils, Molecules, Divergence Times, and the Origin of Lissamphibians [PDF]
Systematic Biology, 2007 A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians from temnospondyls, contrary to recent claims. A supertree is assembled using new Mesquite modules that allow extinct taxa to be incorporated into a time-calibrated ...

Genome-wide tests for introgression between cactophilic Drosophila implicate a role of inversions during speciation [PDF]
, 2015 K.L. was funded by a junior research fellowship from the National Environmental Research Council, UK (NE/I020288/1, NBAF659).Models of speciation-with-gene-flow have shown that the reduction in recombination between alternative chromosome arrangements ...

Divergence Time Estimation of Aloes and Allies (Xanthorrhoeaceae) Based on Three Marker Genes
Diversity, 2018 Aloes and allies are prominent members of African succulent vegetation and especially of the highly diverse Cape Flora. The main goal of this study was to obtain age estimates for alooids by calibrating a Bayesian phylogenetic analysis based on two ...

Unusual lizard fossil from the Miocene of Nebraska and a minimum age for cnemidophorine teiids [PDF]
Royal Society Open Science, 2020 Teiid lizards are well represented in the fossil record and are common components of modern ecosystems in North and South America. Many fossils were referred to the cnemidophorine teiid group (whiptails, racerunners and relatives), particularly from ...
