Bats (Chiroptera) represent one of the largest and most diverse radiations of mammals, accounting for one-fifth of extant species. [] Key Result Phylogenetically informed comparisons of the new taxon with other bats and non-flying mammals reveal that critical morphological and functional changes evolved incrementally.
Evolutionary History of Bats: Systematics and paleobiogeography of early bats
TLDR
The term “early bats” is restricted to the species known from the Early and early-middle Middle Eocene (Ypresian and Lutetian, and global equivalents, encompassing European mammalian reference levels MP7 through MP13).
Evolutionary biology: A first for bats
TLDR
New Green River bat fossils — including two near-complete skeletons, a cast of one of which is shown on the cover — looks to have settled the matter in favour of flight first, and a new species is the most primitive bat known.
Phylogeny, Genes, and Hearing: Implications for the Evolution of Echolocation in Bats
TLDR
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.
Making a bat: The developmental basis of bat evolution
TLDR
This review of current and ongoing studies on bat evolution highlights key aspects of studies that have used bats as a model for morphological adaptations, diversification during adaptive radiations, and morphological novelty, and investigates morphological specialization by reviewing current knowledge about wing and face evolution.
Early diversification trend and Asian origin for extent bat lineages

TLDR
The reconstruction of the ancestral distribution suggests an Asian origin for bats, thereby indicating that the current panglobal but disjunct distribution pattern of extant bats may be related to events involving seriate cross‐continental dispersal and local extinction, as well as the influence of geological events and the expansion and contraction of megathermal rainforests during the Tertiary.
Fleas (Siphonaptera) are Cretaceous, and Evolved with Theria
TLDR
A molecular phylogenetic study based on a comprehensive taxon sampling of 259 flea taxa, suggesting that Theria (placental mammals and marsupials) represent the most likely ancestral host group of extant Siphonaptera, with marsupial occupying a more important role than previously assumed.

33 million year old Myotis (Chiroptera, Vespertilionidae) and the rapid global radiation of modern bats
TLDR
Morphological comparison and phylogenetic analysis confirms that the new, large form from the Belgian early Oligocene locality of Boutersem reveals the presence of a relatively large vespertilionid, making this record the earliest known for that taxon and extending the temporal range of this extant genus to over 33 million years.
Integrating Ontogeny of Echolocation and Locomotion Gives Unique Insights into the Origin of Bats
TLDR
It is found clear evidence that the ability to hear high frequency echolocation-like sounds preceded the able to produce it and that a simple eCholocation system was likely inherited from a shrew-like ancestor and was not an in situ evolutionary innovation of bats.

Fossil Evidence and the Origin of Bats
TLDR
A new phylogenetic analysis indicates that several early fossil bats are consecutive sister taxa to the extant crown group (including megabats), and suggests a single origin for the order, at least by the late Paleocene.
The evolution of flight and echolocation in bats: another leap in the dark
TLDR
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.
A nuclear DNA phylogenetic perspective on the evolution of echolocation and historical biogeography of extant bats (chiroptera).
TLDR
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.
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.

Oldest placental mammal from sub-Saharan Africa: Eocene microbat from Tanzania - Evidence for early evolution of sophisticated echolocation
A partial skeleton of a new fossil microbat, Tanzanycteris mannardi, is the oldest placental mammal found in sub-Saharan Africa. It came from early Lutetian (46 Ma) lake sediments in north-central
Cochlea size in extant chiroptera and middle eocene microchiropterans from messel
TLDR
The aim of the present study is to establish the relations of cochlea size of six fossil species of three families from Messel and 298 extant chiropterans of all major higher taxa by comparison with taxa of extant bats with known echolocation and foraging behavior.
Early Eocene Bat from Wyoming
A fossil skeleton of an early Eocene bat, the oldest known flying mammal, was found in southwest Wyoming. The bat is assigned to the new species Icaronycteris index of the suborder Microchiroptera.
