Phylogenetic utility of mitochondrial and nuclear genes: a case study in the diptera (true flies)
… groupings in need of further analysis. For divergence time estimation, we show widespread convergence of clade age estimates from both mitochondrial and nuclear gene sources under a wide variety of data preparation and model paradigms. Our results indicate slightly superior performance of …

The Influence of Structural Constraints on Protein Evolution
… models on simulatedand empirical data for divergence time estimation, tree inference, side chain configurationprediction and ancestral sequence reconstruction.Further, encoding observed characters in an alignment as ambiguous representations ofcharacters in a larger state-space allows the …

Multi-locus phylogenetic inference of the howler monkey (Alouatta) radiation in South America.
… from those proposed in previous studies, the divergence time estimation analyses recovered similar dates to other investigations. The age of the genus <em>Alouatta </em>was estimated at ca. 6.1 Mya (95% Highest Posterior Density, or HPD = 5.2 - 6.9 Mya). The Meso-American clade containing …

Biogeography and phylogenetics of grassland auchenorrhyncha
… infer biogeographic patterns and to estimate divergence times. Grass feeding in Deltocephalini was inferred to be Palearctic in origin, and Old World origins were inferred for each target lineage. Hecalini and Paralimnini were inferred to be Palearctic in origin, while Deltocephalini + …

The Last Stand of Angraecum: Biogeographic and Evolutionary History of Darwin's Muses
… only a few of its taxa. Herein, phylogenetic, divergence-time estimation, and historical-biogeographical analyses were conducted using a comprehensive molecular dataset of six loci for Angraecinae with the objective of reconstructing ancestral areas of distribution of the subtribe. The results …

Next generation sequencing technology and phylogenomics enhance the resolution of deep node phylogenies: A study of the Protostomia
… and phylogenomic reconstruction methods and divergence time estimation experiments were implemented to uncover the eventful 520 million year evolutionary history of these ancient carnivores. Results from these experiments show that the chaetognaths are unequivocally protostomes with a …
