Bats (order Chiroptera) are one of the few orders of mammals that echolocate and the only group with the capacity for powered flight. [] Key Result Here we present a phylogenetic analysis of bat relationships using DNA sequence data from four nuclear genes and three mitochondrial genes (total of 8,230 base pairs), indicating that microbat families in the superfamily Rhinolophoidea are more closely related to megabats than they are to other microbats.
A nuclear DNA phylogenetic perspective on the evolution of echolocation and historical biogeography of extant bats (chiroptera).
195 morphological characters were evaluated and a morphological synapomorphy characterizing the Rhinolophoidea was identified and is suggestive of a separate origin of echolocation in this clade, as well as the center of origin of modern-day bat families.
The evolution of flight and echolocation in bats: another leap in the dark
A novel hypothesis is advanced, which starts from the assumption that bats are monophyletic and the ancestral pre-bat was arboreal, but diurnal and frugivorous, and overcomes many of the problems identified in previous treatments.
Primitive Early Eocene bat from Wyoming and the evolution of flight and echolocation
A new bat is described from the Early Eocene Green River Formation of Wyoming, USA, with features that are more primitive than seen in any previously known bat, supporting a ‘flight first’ hypothesis for chiropteran evolution.
Phylogeny, Genes, and Hearing: Implications for the Evolution of Echolocation in Bats
In this chapter, the consensus and conflict regarding bat evolutionary relationships is explored based on key phylogenetic studies conducted over the past 15 years, and the potential molecular sensory trade-offs between echolocation, vision, olfaction, and taste are explored.
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 challenge
Molecular evolution of bat color vision genes.
Surprisingly, the S opsin in these bats may be sensitive to UV light, which is relatively more abundant at dawn and at dusk, which may provide insights into the effect of nocturnal life on the evolution of opsin genes in mammals and the Evolution of the life history traits of bats in general.

The adaptive signatures discovered in the genomes of megabats may provide crucial insight into their distinct evolution, including key processes such as virus resistance, loss of echolocation, and frugivorous feeding.
Phylogenomic Analyses Elucidate the Evolutionary Relationships of Bats
Gene structure and evolution of transthyretin in the order Chiroptera
Based on TTR intron 1 sequence, the inferred evolutionary relationship within Chiroptera revealed more closely relatedness of R. affinis to megabats than to microbats, and the paraphyly of microbats was suggested.
Results of the analyses strongly support other recent work indicating that Archonta is not a natural assemblage and that the sister taxon to Chiroptera may include CetartiodactylA, Perissodactyla, Carnivora, and possibly Pholidota.


Endemic African mammals shake the phylogenetic tree
DNA sequences from three mitochondrial genes and two nuclear genes are analysed to examine relationships of insectivores to other mammals and suggest that there was an extensive African radiation from a single common ancestor that gave rise to ecologically divergent adaptive types.
Complete Mitochondrial Genome of a Neotropical Fruit Bat, Artibeus jamaicensis, and a New Hypothesis of the Relationships of Bats to Other Eutherian Mammals
The hypothesis regarding the relationship of bats to other eutherian mammals is concordant with previous molecular studies and contrasts with hypotheses based solely on morphological criteria and an incomplete fossil record.
Origin and Evolution of Gliding in Early Cenozoic Dermoptera (Mammalia, Primatomorpha)
Despite the differences in extant diversity, bats, whales, and colugos are distinctive components of the Earth’s biota primarily because of the suites of diagnostic attributes they possess as a result of the key innovations that occurred earlier in their respective histories.
No cost of echolocation for bats in flight
The energy costs of flight in two species of small echolocating Microchiroptera were measured using a novel combination of respirometry and doubly-labelled water and flight energy expenditure was not significantly different between echoling bats and non-echolocating bats and birds.
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),
Comparison morphology and paleontology offer some compelling hypotheses that comprise a framework for studies of macromolecular traits that support groupings of the Recent orders of eutherian mammals.
Primates and Their Relatives in Phylogenetic Perspective
A molecular view of Primate Supraordinal Relationships from the Analysis of Both Nucleotide and Amino Acide Sequences and the Role of the Neurosciences in Primate Evolutionary Biology is presented.
Evidence for echolocation in the common shrew, Sorex araneus
It is shown that, like four North American soricid shrew species, the European common shrew Sorex araneus L. is able to use echolocation to identify open and closed tubes at a distance of 200 mm.
Relative apparent synapomorphy analysis (RASA). I: The statistical measurement of phylogenetic signal.
The investigation of the utility and limitations of RASA using simulated and bacteriophage T7 data sets indicates that the method has numerous advantages over existing measures of signal and promises to be useful in the development of new techniques that should increase the rigor and reliability of phylogenetic estimates.
Additional support for Afrotheria and Paenungulata, the performance of mitochondrial versus nuclear genes, and the impact of data partitions with heterogeneous base composition.
After eliminating third positions of A2AB, IRBP, and vWF, nuclear data agree with mitochondrial data in supporting cow + horse, and nuclear genes provide stronger support for both Afrotheria and Paenungulata.
