The genus Sylvilagus, which comprises the New World cottontail rabbits, contains several commercially important as well as endangered (or threatened) species. Understanding the evolution of this group is pertinent to their management and conservation. The purpose of this study was to examine the evolutionary history of the cottontails using sequence data from the mitochondrial 12S rRNA gene. The 12S data provide a robust phylogeny which was supported under a variety of phylogenetic approaches…

Illuminating the obscured phylogenetic radiation of South American Sylvilagus Gray, 1867 (Lagomorpha: Leporidae)
TLDR
It is concluded that only a molecular phylogeny based on a broader taxonomic representation will fully resolve leporid phylogeny.
Molecular Phylogeny of Cyprinid Fishes of India Using 12s rRNA Gene Sequences
TLDR
The phylogenetic tree constructed based on these 12S rRNA gene sequences suggests the possible occurrence of three subfamilies, namely, Schizothoracinae, Cyprininae and Rasborinae within the family CyPRinidae.
CHROMOSOMES AND PHYLOGEOGRAPHY OF SYLVILAGUS (MAMMALIA, LEPORIDAE) FROM EASTERN BRAZIL
TLDR
Molecular and karyotypic data suggest that the diversity in the study area may be larger than that reported in the literature on the basis of external characters.
Phylogeny and evolutionary origins of the Leporidae: a review of cytogenetics, molecular analyses and a supermatrix analysis
TLDR
It is held that of the polytypic genera Lepus remains the most problematic, and a working hypothesis is provided that will hopefully encourage future research on the various hare species.
Mitochondrial differentiation, introgression and phylogeny of species in the Tegenaria atrica group (Araneae: Agelenidae)
TLDR
Molecular clock calibrations (CO1) suggest that deeper divisions within the genus Tegenaria may be in excess of 10 million years old, and that the evolutionary history of the T. atrica group has been moulded by Quaternary glacial–interglacial  cycles.
Taxonomic status of the Davis Mountains cottontail, Sylvilagus robustus, revealed by amplified fragment length polymorphism
TLDR
Results from phylogenetic and population genetic analyses suggest a significant lack of gene flow between the 2 species and support recognition of S. robustus as a separate species.
Cytochrome b phylogeny of North American hares and jackrabbits (Lepus, lagomorpha) and the effects of saturation in outgroup taxa.
TLDR
An initial phylogenetic framework for jackrabbits and hares is provided and the trees indicate that the taxonomic status of some species needs to be reassessed and that species of Lepus within North America do not form a monophyletic entity.
Hybridization and polymorphic microsatellite markers for two lagomorph species (Genus Sylvilagus): implications for conservation
TLDR
The mitochondrial 12S gene may be a convenient molecular marker for the resolution of species identity questions and information on microsatellites, occurrence of natural hybridization, and a molecular markers for species resolution will be useful for developing management plans for lagomorphs and focusing further research on factors affecting population status.
ALLOZYME VARIATION OF COTTONTAIL RABBITS (SYLVILAGUS) FROM MEXICO
TLDR
S. floridanus was the most genically variable rabbit as revealed by mean number of alleles per locus and percentage of polymorphic loci, and the fixation index showed genetic differentiation among species.
Low, Complex and Probably Reticulated Chromosome Evolution of Sciuromorpha (Rodentia) and Lagomorpha
TLDR
It is proposed that reticulated evolution occurred during the diversification of Glires, which implies that several pericentric inversions and Robertsonian translocations were conserved in the heterozygous status for an extensive period, and concluded that a reticulation took place early during the evolution of both families and lasted longer in Sciuridae than in Leporidae.

Evolution of chromosomal variation in cottontails, genus Sylvilagus (Mammalia: Lagomorpha): S. aquaticus, S. floridanus, and S. transitionalis.
TLDR
The banding patterns of mitotic chromosome from three cottontail species are presented and compared with those of the proposed leporid ancestral karyotype, the latter being reflected in a species of hare, Lepus saxatilis (2n = 48).
Evolution of chromosomal variation in cottontails, genus Sylvilagus (Mammalia: Lagomorpha). II. Sylvilagus audubonii, S. idahoensis, S. nuttallii, and S. palustris.
TLDR
The evolutionary restructuring of the genomes of these species was traced by comparing their banded chromosomes to those of Lepus saxatilis, a species of hare in which the leporid ancestral karyotype is thought to have been conserved.
Among-site rate variation and phylogenetic analysis of 12S rRNA in sigmodontine rodents.
We analyze sequences from two mitochondrial genes, cytochrome b (cyt b) and 12S rRNA (12S), for a group of sigmodontine rodents among which phylogenetic relationships are well understood based on…
TESTING HYPOTHESES OF CHAETOGNATH ORIGINS: LONG BRANCHES REVEALED BY 18S RIBOSOMAL DNA
TLDR
Testing specific hypotheses of chaetognath affinities to nematodes, mollusks, acanthocephalans, and deuterostomes supported the monophyly of a chaet Cognatha-nematode clade, and an evolutionary scenario for the origin of the Chaetognatha lineage from a vermiform benthic organism was presented.
Compensatory substitutions and the evolution of the mitochondrial 12S rRNA gene in mammals.
TLDR
12S ribosomal RNA (rRNA) gene sequences from a suite of mammalian taxa, for which phylogenetic relationships are well established based on independent criteria, were employed to study the evolution of this gene, producing a phylogeny that agrees with expectations.
Molecular evolution of mitochondrial 12S RNA and cytochrome b sequences in the pantherine lineage of Felidae.
TLDR
DNA sequence comparisons of two mitochondrial DNA genes were used to infer phylogenetic relationships among 17 Felidae species, notably 15 in the previously described pantherine lineage, and suggested the recognition of a recently evolved monophyletic genus Panthera.
Nucleotide sequence variation in the mitochondrial 12S rRNA gene and the phylogeny of African mole-rats (Rodentia: Bathyergidae).
TLDR
The independent origin of the common mole- rat, relative to the naked mole-rat, suggests that complex social systems evolved in parallel along different bathyergid lineages, and Bathyergid rodents appear to fall at the extreme end of the spectrum of mammalian variation, with respect to both transition/transversion ratios and divergence.
Evolution of the cytochrome b gene of mammals.
TLDR
Comparisons of these cytochrome b sequences support current structure-function models for this membrane-spanning protein, which suggests that the outer surface which includes the Qo redox center is more constrained than the remainder of the molecule, namely, the transmembrane segments and the surface that protrudes into the mitochondrial matrix.
Ribosomal RNA secondary structure: compensatory mutations and implications for phylogenetic analysis.
TLDR
This analysis indicates that characters from both base-pairing regions (stems) and non-base-paired regions (loops) contain phylogenetic information, as judged by the level of support of the phylogenetic results compared with a well-established tree based on both morphological and molecular data.
BANDING STUDIES IN THE VOLCANO RABBIT, ROMEROLAGUS DIAZI AND CRAWSHAY'S HARE LEPUS CRAWSHAYI. EVIDENCE OF THE LEPORID ANCESTRAL KARYOTYPE
TLDR
Observations support the hypothesis that the leporid ancestral karyotype has been maintained in the hares and certain of the rabbit taxa and indicate a common evolutionary origin of the two genera.
