Molecular phylogeny and divergence times of deuterostome animals.
The phylogenetic relationships among deuterostome animals have been debated for many years, and a diversity of hypotheses have been proposed based on both morphological and molecular data. Here we have assembled sequences of 217 nuclear-encoded proteins to address specific questions concerning their relationships and times of origin. We recovered significant support for urochordates as the clos...
متن کاملMolecular phylogeny and divergence times of drosophilid species.
The phylogenetic relationships and divergence times of 39 drosophilid species were studied by using the coding region of the Adh gene. Four genera--Scaptodrosophila, Zaprionus, Drosophila, and Scaptomyza (from Hawaii)--and three Drosophila subgenera--Drosophila, Engiscaptomyza, and Sophophora--were included. After conducting statistical analyses of the nucleotide sequences of the Adh, Adhr (Adh...
متن کاملDeciphering deuterostome phylogeny: molecular, morphological and palaeontological perspectives.
Deuterostomes are a monophyletic group of animals that include the vertebrates, invertebrate chordates, ambulacrarians and xenoturbellids. Fossil representatives from most major deuterostome groups, including some phylum-level crown groups, are found in the Lower Cambrian, suggesting that evolutionary divergence occurred in the Late Precambrian, in agreement with some molecular clock estimates....
متن کاملMolecular phylogeny, divergence times and biogeography of spiders of the subfamily Euophryinae (Araneae: Salticidae).
We investigate phylogenetic relationships of the jumping spider subfamily Euophryinae, diverse in species and genera in both the Old World and New World. DNA sequence data of four gene regions (nuclear: 28S, Actin 5C; mitochondrial: 16S-ND1, COI) were collected from 263 jumping spider species. The molecular phylogeny obtained by Bayesian, likelihood and parsimony methods strongly supports the m...
متن کاملPhylogeny and divergence times in Pinaceae: evidence from three genomes.
In Pinaceae, the chloroplast, mitochondrial, and nuclear genomes are paternally, maternally, and biparentally inherited, respectively. Examining congruence and incongruence of gene phylogenies among the three genomes should provide insights into phylogenetic relationships within the family. Here we studied intergeneric relationships of Pinaceae using sequences of the chloroplast matK gene, the ...
