Resolution of the Early Placental Mammal Radiation Using Bayesian Phylogenetics
TLDR
Crown-group Eutheria may have their most recent common ancestry in the Southern Hemisphere (Gondwana), and placental phylogeny is investigated using Bayesian and maximum-likelihood methods and a 16.4-kilobase molecular data set. Expand
Parallel adaptive radiations in two major clades of placental mammals
TLDR
Two independent molecular data sets, having aligned lengths of DNA of 5,708 and 2,947 base pairs, respectively, are analysed for all orders of placental mammals to resolve placental orders into four groups: Xenarthra, Afrotheria, Laurasiatheria, and Euarchonta plus Glires. Expand
Linnaeus was right all along: Ulva and Enteromorpha are not distinct genera
TLDR
Preliminary results provide strong evidence that Ulva, Enteromorpha and Chloropelta are not distinct evolutionary entities and should not be recognized as separate genera. Expand
Molecular evidence for multiple origins of Insectivora and for a new order of endemic African insectivore mammals.
The traditional views regarding the mammalian order Insectivora are that the group descended from a single common ancestor and that it is comprised of the following families: Soricidae (shrews),Expand
Molecules consolidate the placental mammal tree.
TLDR
The emerging tree has revealed numerous instances of convergent evolution and suggests a role for plate tectonics in the early evolutionary history of placental mammals. Expand
Molecular phylogenetic evidence refuting the hypothesis of Batoidea (rays and skates) as derived sharks.
TLDR
The phylogenetic placement of batoids as a basal elasmobranch lineage means that much of the current thinking regarding the evolution of morphological and life history characteristics in elasmOBranchs needs to be re-evaluated. Expand
Evolution of the core and pan-genome of Streptococcus: positive selection, recombination, and genome composition
TLDR
Recombination is an important evolutionary force in shaping Streptococcus genomes, not only in the acquisition of significant portions of the genome as lineage specific loci, but also in facilitating rapid evolution of the core-genome. Expand
Independent adaptation to riverine habitats allowed survival of ancient cetacean lineages.
TLDR
Using phylogenetic analyses of nucleotide sequences from three mitochondrial and two nuclear genes, it is demonstrated with statistical significance that extant river dolphins are not monophyletic and suggested that they are relict species whose adaptation to riverine habitats incidentally insured their survival against major environmental changes in the marine ecosystem or the emergence of Delphinidae. Expand
Molecular evidence regarding the origin of echolocation and flight in bats
TLDR
A phylogenetic analysis of bat relationships using DNA sequence data from four nuclear genes and three mitochondrial genes indicates that microbat families in the superfamily Rhinolophoidea are more closely related to megabats than they are to other microbats, which implies that echolocation systems either evolved independently in rhinlophoids and otherMicrobat monophyly is uncorroborated by molecular data. Expand
Microbat paraphyly and the convergent evolution of a key innovation in Old World rhinolophoid microbats
Molecular phylogenies challenge the view that bats belong to the superordinal group Archonta, which also includes primates, tree shrews, and flying lemurs. Some molecular studies also challengeExpand
