The highly endangered solenodons, endemic to Cuba (Solenodon cubanus) and Hispaniola (S. paradoxus), comprise the only two surviving species of West Indian insectivores. Combined gene sequences (13.9 kilobases) from S. paradoxus established that solenodons diverged from other eulipotyphlan insectivores 76 million years ago in the Cretaceous period, which is consistent with vicariance, though also compatible with dispersal. A sequence of 1.6 kilobases of mitochondrial DNA from S. cubanus… 
An extinct monkey from Haiti and the origins of the Greater Antillean primates
A new extinct Late Quaternary platyrrhine from Haiti, Insulacebus toussaintiana, is described here from the most complete Caribbean subfossil primate dentition yet recorded, demonstrating the likely
Solenodon paradoxus (Soricomorpha: Solenodontidae)
S. paradoxus is 1 of 2 extant species in the genus Solenodon, and 2 subspecies are recognized; the species is one of few venomous mammals with venom delivery through a channel in a modified lower incisor.
Molecular phylogenetic analysis of nuclear genes suggests a Cenozoic over-water dispersal origin for the Cuban solenodon
Molecular phylogenetic analyses of five nuclear genes from 35 species of the mammalian order Eulipotyphla suggest that S. cubanus and its ancestral lineage originated via over-water dispersal rather than vicariance events, as had previously been hypothesised.
Multilocus phylogeny and cryptic diversity in Asian shrew-like moles (Uropsilus, Talpidae): implications for taxonomy and conservation
The cryptic diversity found in this study indicated that the number of species is strongly underestimated under the current taxonomy, and two synonyms of gracilis should be given full species status and the taxonomic status of another three potential species should be evaluated using extensive taxon sampling, comprehensive morphological, and morphometric approaches.
The Earliest Caribbean Rodents: Oligocene Caviomorphs from Puerto Rico
ABSTRACT The Greater Antilles was once home to a diverse array of endemic groups of caviomorph rodents. Many of these became extinct, together with endemic insectivores, sloths, and primates, in
Mitogenomic sequences support a north–south subspecies subdivision within Solenodon paradoxus
A mitogenomic phylogeny confirmed the basal position of solenodons relative to shrews and moles, with solenodon mitogenomes estimated to have diverged from those of other mammals ca.
Major Caribbean and Central American frog faunas originated by ancient oceanic dispersal
Molecular clock analyses reject the prevailing hypothesis that these frogs arose from land connections with North and South America and their subsequent fragmentation in the Late Cretaceous, and suggest Origin by dispersal, probably over water from South America in the early Cenozoic is more likely.
Postcranial Morphology of Apheliscus and Haplomylus (Condylarthra, Apheliscidae): Evidence for a Paleocene Holarctic Origin of Macroscelidea
Evidence for a Paleocene Holarctic Origin of Macroscelidea is found and Ungulata and ungulate refer to the traditional morphological concept of this group, minimally including Artiodactyla, PerissodactylA, Hyracoidea.
Description of a new species of the genus Uropsilus (Eulipotyphla: Talpidae: Uropsilinae) from the Dabie Mountains, Anhui, Eastern China
A new species of shrew mole is described, named Uropsilus dabieshanensis sp.


Molecular estimates of divergence times between island taxa and their mainland counterparts indicate a Cenozoic origin for nearly all groups examined, and data from different sources point to an origin by over 65 million years.
Rafting Mammals or Drifting Islands?: Biogeography of the Greater Antillean Insectivores Nesophontes and Solenodon
Distributional evidence from numerous other elements of the Caribbean biota support the biogeographic hypothesis proposed for Nesophontes and Solenodon, which are island relicts of a once more widespread ancestral distribution of soricomorph insectivores.
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),

Molecular data from diverse West Indian amphibians and reptiles and their mainland relatives support a more recent derivation of the Antillean vertebrate fauna by overwater dispersal.
Classification of mammals : above the species level
Malcolm C. McKenna and Susan K. McKenna inherited the project from Simpson and, with Bell, has constructed a completely updated hierarchical system that reflects the genealogy of Mammalia.
Resolution of the Early Placental Mammal Radiation Using Bayesian Phylogenetics
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.
Phylogenetic Relationships of the Order Insectivora Based on Complete 12S rRNA Sequences from Mitochondria
It is suggested that the 12S rRNA sequences lack the ability to resolve relationships extending into this period, which would explain the polyphyly, unusual affinities, and low support derived in this and other studies employing 12S sRNA sequences to diagnose relationships among eutherian orders.
A phylogenetic analysis of cranial, dental, and postcranial characters of 30 fossil and Recent taxa leads to the conclusion that the Apternodontidae is not monophyletic and should be restricted to seven species of Apternodus.

A Morphological Basis for Assessing the Phylogeny of the “Tenrecoidea” (Mammalia, Lipotyphla)
A phylogenetic analysis of 35 mammalian taxa focusing on the lipotyphlan family Tenrecidae, based on 193 morphological character states across 71 characters, is undertaken to test several hypotheses
