Fluorescence in situ hybridization (FISH) was used to define homologous segments among representatives of 7 of the 11 recognized leporid genera. Chromosome painting using 22 rabbit chromosome-specific paints derived from flow-sorted chromosomes revealed that at least 18 fusions and six fissions differentiate the extant karyotypes from the presumed ancestral state (2n = 48). The riverine rabbit, Bunolagus monticularis, has the most derived karyotype, differing from the ancestor by seven fusions…

Molecular genetics of Rhabdomys subspecies boundaries : phylogeography of mitochondrial lineages and chromosomal fluorescence in situ hybridization
TLDR
The results suggest that mouse chromosomes 1, 10, and 17 have undergone extensive rearrangements during genome evolution in the murids and may be useful markers for enhancing the understanding of the mode and tempo of chromosome evolution in rodents.
Reconstruction of karyotype evolution in core Glires. I. The genome homology revealed by comparative chromosome painting
TLDR
It is suggested that Lagomorpha and Sciuridae should be considered as core Glires lineages, characterized by cytogenetically conserved karyotypes which contain chromosomal elements inherent to karyotype of common Glires ancestor.
Comparative cytogenetics of rodents
TLDR
Analysis of data on comparative chromosome painting produced using various chromosome-specific libraries for members of different Glires groups shows that the modern rodents can be conventionally classified into two groups with sharply differing directions and tempos of karyotypic evolution.
The Evolution of Human Chromosome 7 Syntenies in Eutheria, with Special Attention to Primates
TLDR
This review critically describes current information concerning the evolution of human chromosome 7 orthologous in several Eutherian groups and proposes a chronologically fossil-tuned dynamic of the synteny.
Phylogenomics of African guenons
TLDR
It is proposed that the Cercopithecini evolution proceeded by either repeated fission events facilitated by peculiar genomic structures or successive reticulate phases, in which heterozygous populations for few rearranged chromosomes were present, allowing the spreading of chromosomal forms in various combinations, before the speciation process.
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.
The telomeric sync model of speciation: species-wide telomere erosion triggers cycles of transposon-mediated genomic rearrangements, which underlie the saltatory appearance of nonadaptive characters
TLDR
Evidence is presented for the existence of a cell biological mechanism that strongly points to the almost forgotten European concept of saltatory evolution of nonadaptive characters, which is in perfect agreement with the gaps in the fossil record.
An Annotated Draft Genome of the Mountain Hare (Lepus timidus)
TLDR
The results validate previous reference-based strategies and suggest that the chromosome-scale hare draft genome should enable chromosome-wide analyses and genome scans on hares.
Conserved although Very Different Karyotypes in Gliridae and Sciuridae and Their Contribution to Chromosomal Signatures in Glires
TLDR
Although both Sciuridae and Gliridae karyotypes are relatively conserved, they display many differences, indicating their early divergence, and it is shown that the speed of chromosomal evolution in Glirids is intermediate between that of Sciur Families and Muridae.
Retroposon insertions provide insights into deep lagomorph evolution.
TLDR
The position of Pronolagus outside of the remaining leporids supports the sequence-based signals of nuclear genes and clearly refutes the misleading signals of mitochondrial genes.

Conservation of human vs. feline genome organization revealed by reciprocal chromosome painting.
TLDR
The results suggest that reciprocal chromosome painting will help reconstruct the history of genomic changes by determining the polarity of chromosomal rearrangements and establishing the ancestral karyotype for each principle branching point in mammalian evolution.
Chromosomal homeologies between human, harbor seal (Phoca vitulina) and the putative ancestral carnivore karyotype revealed by Zoo-FISH
TLDR
Comparison with Zoo-FISH maps of other species reveals that the harbor seal shares a high degree of karyotypic homeology with the human complement and an even higher degree with the conordinal cat complement, suggesting that pinniped, felid and human karyotypes have maintained conserved complements.
Complete homology maps of the rabbit (Oryctolagus cuniculus) and human by reciprocal chromosome painting
TLDR
Many conserved chromosome segments found previously in other mammals (e.g. cat, pig, cattle, Indian muntjac) were also found to be conserved in rabbit chromosomes.
Construction of chromosome-specific paints for meta- and submetacentric autosomes and the sex chromosomes in the horse and their use to detect homologous chromosomal segments in the donkey
TLDR
Examination of the accuracy of the available comparative cytogenetic data between horse and donkey finds that the results not only detected conservation of whole chromosome and/or arm synteny between the two karyotypes, but also highlighted varying degrees of rearrangements.
Emerging patterns of comparative genome organization in some mammalian species as revealed by Zoo-FISH.
TLDR
The use of Zoo-FISH to identify regions of chromosomal homology has allowed the transfer of information from map-rich species such as human and mouse to a wide variety of other species, and provided a basis for developing a picture of the ancestral mammalian karyotype.
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).
Comparative chromosome studies in the family Leporidae (Lagomorpha, Mammalia).
TLDR
Comparative studies with the fusion products of Oryctolagus cuniculus indicate that fusion and not fission is the major factor in chromosomal evolution of these leporids.
Phylogenetic position of the order Lagomorpha (rabbits, hares and allies)
TLDR
It is shown that Lagomorpha is significantly more closely related to Primates and Scandentia (tree shrews) than it is to rodents, which raises the possibility that the ancestral eutherian morphotype may have possessed many rodent-like morphological characters.
Multiple Substitutions Affect the Phylogenetic Utility of Cytochrome b and 12S rDNA Data: Examining a Rapid Radiation in Leporid (Lagomorpha) Evolution
TLDR
Phylogenies reconstructed from the 12S rDNA data support hypotheses based on fossil evidence that African rock rabbits are outside of the main leporid stock and that leporids experienced a rapid radiation, but the molecular data suggest that this radiation event occurred in the mid-Miocene several millions of years earlier than the Pleistocene dates suggested by paleontological evidence.
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.
