Establishing the relationships among modern amphibians (lissamphibians) and their ancient relatives is necessary for our understanding of early tetrapod evolution. However, the phylogeny is still intractable because of the highly specialized anatomy and poor fossil record of lissamphibians. Paleobiologists are still not sure whether lissamphibians are monophyletic or polyphyletic, and which ancient group (temnospondyls or lepospondyls) is most closely related to them. In an attempt to address…

The origin of modern amphibians: a re-evaluation

TLDR
A matrix based on data from all three hypotheses and analysed key taxa phylogenetically using both Bayesian inference and parsimony supported the temnospondyl hypothesis of lissamphibian origins.

Focal Review: The Origin(s) of Modern Amphibians

TLDR
The present paper reviews the impact of this fossil on morphological and molecular phylogenies, and divergence timing estimates based on molecular models and the fossil record, and raises questions over either the validity of morphological analyses that support lissamphibian polyphyly or about the possibility of long branch attraction given the short internal divergences and long subsequent branches.

Phylogeny, evolution, and biogeography of Asiatic Salamanders (Hynobiidae).

TLDR
It is hypothesized that the interior desertification from Mongolia to Western Asia began approximately 50 Mya; the Tibetan plateau experienced rapid uplift approximately 40 Mya and reached an altitude of at least 2,500 m; and the Ailao-Red River shear zone underwent the most intense orogenic movement approximately 24 Mya.

Life-history evolution and mitogenomic phylogeny of caecilian amphibians.

A multilocus timescale for the origin of extant amphibians.

Fossils, molecules, divergence times, and the origin of lissamphibians.

A review of the paleontological literature shows that the early dates of appearance of Lissamphibia recently inferred from molecular data do not favor an origin of extant amphibians from

Testing the impact of miniaturization on phylogeny: Paleozoic dissorophoid amphibians.

TLDR
Understanding of the phylogenetic relationships of small dissorophoid amphibians provides a new framework for the discussion of their evolutionary history and the evolution of characters shared by branchiosaurids and/or amphibamids with modern amphibian taxa.

Archaeobatrachian paraphyly and pangaean diversification of crown-group frogs.

TLDR
To explore central controversies on the phylogeny of Anura, nearly 4000 base pairs of mitochondrial and nuclear DNA for the major frog lineages are analyzed and likelihood-based analyses are congruent with morphological evidence in supporting a paraphyletic arrangement of archaeobatrachian frogs.

Molecular phylogeny of frogs (Amphibia: Anura) based on complete mitochondrial genomes and partial nuclear genes

TLDR
A sequence data set combining complete mitochondrial genomes and nine nuclear loci was used to estimate a molecular phylogeny of frogs and tackle long-standing contentious questions, suggesting that the 5' end of the control region is a hot spot of gene rearrangement in frogs.

The complete mitochondrial genome of the relict frog Leiopelma archeyi: Insights into the root of the frog Tree of Life

TLDR
The complete mitochondrial genome of Leiopelma archeyi was sequenced and used along with previously reported frog mt genomes to infer a robust phylogeny of major anuran lineages and provided evidence that the 5′ end of the control region is a hot spot for gene order rearrangement.

TLDR
Strong support of the Batrachia hypothesis from both molecule- and morphology-based studies provides a robust phylogenetic framework that will be helpful to comparative studies among the three living orders of amphibians and will permit better understanding of the considerably divergent vertebral, brain, and digit developmental patterns found in frogs and salamanders.

Archaeobatrachian paraphyly and pangaean diversification of crown-group frogs.

TLDR
To explore central controversies on the phylogeny of Anura, nearly 4000 base pairs of mitochondrial and nuclear DNA for the major frog lineages are analyzed and likelihood-based analyses are congruent with morphological evidence in supporting a paraphyletic arrangement of archaeobatrachian frogs.

New frog family from India reveals an ancient biogeographical link with the Seychelles

TLDR
A burrowing frog from India that is noticeably distinct from known taxa in all anuran families is found and recognized as a new family because of its very distinct morphology and an inferred origin that is earlier than several neobatrachian families.

Molecular evidence for the early history of living amphibians.

TLDR
Evidence from the DNA sequences of four mitochondrial genes that challenges the conventional hypothesis and supports a salamander-caecilian relationship is presented and suggests a more recent (Mesozoic) origin for salamanders and caecilians directly linked to the initial breakup of the supercontinent Pangaea.

Mitochondrial evidence on the phylogenetic position of caecilians (Amphibia: Gymnophiona).

TLDR
The complete nucleotide sequence of the mitochondrial genome of the caecilian Typhlonectes natans (Gymnophiona, Amphibia) was determined and was used to assess the phylogenetic position of caecilians and to gain insights into the origin of living amphibians.

CHAPTER 2 – A NEW PERSPECTIVE ON TETRAPOD PHYLOGENY

Late Jurassic salamanders from northern China

TLDR
The discovery of an extraordinary sample of salamander fossils from the Upper Jurassic of China is reported, providing compelling evidence for an Asian origin of Recent salamanders, as well as for an extensive and early radiation of several major lineages.

Tetrapod phylogeny inferred from 18S and 28S ribosomal RNA sequences and a review of the evidence for amniote relationships.

TLDR
The 18S ribosomal RNAs of 21 tetrapods were sequenced and aligned with five published tetrapod sequences, showing that three genes unambiguously support a bird-mammal relationship, compared with one gene (histone H2B) that favors aBird-crocodilian clade.

TLDR
Adult anatomy and patterns of development in frogs and salamanders support their origin from different families of dissorophoid labyrinthodonts, and the ancestry of amniotes apparently lies among very early anthracosaurs.
