The complete nucleotide sequence of a snake (Dinodon semicarinatus) mitochondrial genome with two identical control regions.
TLDR
Southern hybridization experiments using mtDNAs purified from multiple akamata individuals showed that the duplicate state of the control region is not a transient or unstable feature found in a particular individual, but that it stably occurs in mitochondrial genomes of the species.

Sequence evolution of mitochondrial tRNA genes and deep-branch animal phylogenetics
TLDR
It is proposed that mitochondrial tRNAs may be useful in resolving deep branches in animal phylogenies with divergences that occurred some hundreds of Myr ago and designed a set of primers with which mtDNA fragments encompassing clustered tRNA genes were successfully amplified from various vertebrates by the polymerase chain reaction.

Gene rearrangements in snake mitochondrial genomes: highly concerted evolution of control-region-like sequences duplicated and inserted into a tRNA gene cluster.
TLDR
The results suggest that the duplicate state of the control-region-like sequences has long persisted in snake mtDNAs, possibly since the original insertion of theControl- Region-like sequence and tRNA(Leu) gene into the tRNA gene cluster, which occurred in the early stage of the divergence of snakes.

Complete mitochondrial DNA sequences of the green turtle and blue-tailed mole skink: statistical evidence for archosaurian affinity of turtles.
TLDR
It is likely that turtles originated from a Permian-Triassic archosauromorph ancestor with two pairs of temporal fenestrae behind the skull orbit that were subsequently lost and the traditional classification of turtles in the Anapsida may need to be reconsidered.

Mitogenomic evaluation of the historical biogeography of cichlids toward reliable dating of teleostean divergences
TLDR
It is proposed to add the biogeographic assumption of cichlid divergences by continental fragmentation as effective time constraints in dating teleostean divergence times to achieve a considerable reduction in credibility intervals in the estimated divergence times.

Complete Mitochondrial DNA Sequences of Six Snakes: Phylogenetic Relationships and Molecular Evolution of Genomic Features
TLDR
A new phylogenetic relationship among the major families of snakes is suggested: ((Viperidae, Colubridae), Acrochordidae), (((Pythonidae, Xenopeltidae), Cylindrophiidae), Boidae)), Leptotyphlopidae).

Molecular phylogeny of osteoglossoids: a new model for Gondwanian origin and plate tectonic transportation of the Asian arowana.
TLDR
This study proposes a new model whereby the Asian arowana vicariantly diverged from the Australasian arowanas in the eastern margin of Gondwanaland and migrated into Eurasia on the Indian subcontinent or smaller continental blocks and implicates the relatively long absence of osteoglossiform fossil records from the Mesozoic.

TLDR
It is likely that the apparent similarity of the tongue structure between snakes and varanoids independently evolved and that the duplication of the control region occurred on a snake lineage after divergence of the blind snake.

Sister group relationship of turtles to the bird-crocodilian clade revealed by nuclear DNA-coded proteins.
TLDR
Cloned and sequenced two nuclear genes encoding the catalytic subunit of DNA polymerase alpha and glycinamide ribonucleotide synthetase-aminoimidazole ribon DNA synthetases from amniotes and an amphibian showed that turtles are the sister group to a monophyletic cluster of archosaurs.
