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.Abstract:
Molecular phylogenetic studies have resolved placental mammals into four major groups, but have not established the full hierarchy of interordinal relationships, including the position of the root. The latter is critical for understanding the early biogeographic history of placentals. We investigated placental phylogeny using Bayesian and maximum-likelihood methods and a 16.4-kilobase molecular data set. Interordinal relationships are almost entirely resolved. The basal split is between Afrotheria and other placentals, at about 103 million years, and may be accounted for by the separation of South America and Africa in the Cretaceous. Crown-group Eutheria may have their most recent common ancestry in the Southern Hemisphere (Gondwana).read more

Enamel microstructure evolution in anthracotheres (Mammalia, Cetartiodactyla) and new insights on hippopotamoid phylogeny

TL;DR: Investigations on enamel microstructure provided new data for the debate on hippopotamid origin, and showed a diversity of patterns relevant to phylogenetic inferences within Hippopotamoidea that prove to be particularly relevant for future phylogenetic analysis of the superfamily.

The evolution of echolocation in bats: a comparative approach
TL;DR: It was found that early divergences and subsequent constraints in evolutionary history have resulted in a greater variety of bat call structures than appear to be functionally necessary, suggesting that the proto-bat was a slow and manoeuvrable flier with an opportunistic and omnivorous diet.

Adaptive Evolution in the Glucose Transporter 4 Gene Slc2a4 in Old World Fruit Bats (Family: Pteropodidae)
TL;DR: Preliminary evidence that the Slc2a4 gene has undergone adaptive changes in Old World fruit bats in relation to their ability to meet the demands of a high sugar diet is presented.

TL;DR: Functional variation in the color vision of nocturnal mammals and a distinctive visual ecology of early primates, perhaps one that demanded greater spatial resolution under light levels that could support cone-mediated color discrimination are suggested.

Pavel Hulva,Ivan Horáček +1 more
TL;DR: The results suggest close proximity of Craseonycteris to Hipposideridae rather than to Rhinopomatidae, close relationships between Megadermatidae and Rhinolophidae, sister group position of Pteropodidae to RhInolophoidea, and closer affiliation of Nycteridae with the infraorder Yangochiroptera.

An Empirical Test of Bootstrapping as a Method for Assessing Confidence in Phylogenetic Analysis
David M. Hillis,James J. Bull +1 more
TL;DR: This work uses computer simulations and a laboratory-generated phylogeny to test bootstrapping results of parsimony analyses, and indicates that any given bootstrap proportion provides an unbiased but highly imprecise measure of repeatability, unless the actual probability of replicating the relevant result is nearly one.

A molecular timescale for vertebrate evolution
Sudhir Kumar,S. Blair Hedges +1 more
TL;DR: The clock-like accumulation of sequence differences in some genes provides an alternative method by which the mean divergence time can be estimated, and the molecular times agree with most early and late fossil-based times, but indicate major gaps in the Mesozoic fossil record.

Markov Chasin Monte Carlo Algorithms for the Bayesian Analysis of Phylogenetic Trees

TL;DR: The Bayesian framework for analyzing aligned nucleotide sequence data to reconstruct phylogenies, assess uncertainty in the reconstructions, and perform other statistical inferences is developed and a Markov chain Monte Carlo sampler is employed to sample trees and model parameter values from their joint posterior distribution.
