Karyotypic fissioning and canid phylogeny.
TLDR
This theory accounts for the wide variation in diploid number among the Mammalia and relates the presumed episodes of karyotypic fissioning with known periods of explosive speciation and adaptive radiation and the traditional evolutionary concept of mutant allele substitution through gene frequency shift under the influence of natural selection is placed in a new perspective.About:

Journal ArticleDOI
Building large trees by combining phylogenetic information: a complete phylogeny of the extant Carnivora (Mammalia).
TL;DR: A complete phylogeny for all 271 extant species of the Garnivora is derived, providing a ‘consensus’ estimate of carnivore phylogeny and showing that some lineages within the Mustelinae and Canidae contain significantly more species than expected for their age, illustrating the tree's utility for studies of macroevolution.

Reconstructing contiguous regions of an ancestral genome
Webb Miller,Jian Ma +1 more
TL;DR: A new method is described for predicting the ancestral order and orientation of those intervals from their observed adjacencies in modern species, and a map of an early mammalian genome is produced that accounts for 96.8% of the available human genome sequence data.
Journal ArticleDOI
Emerging Patterns of Comparative Genome Organization in Some Mammalian Species as Revealed by Zoo-FISH
TL;DR: 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.
Journal ArticleDOI
Karyotype evolution in Australian ants
TL;DR: The data provide little support for the ancestral chromosome number in ants having been high with subsequent reduction, but suggest that the ancestral number was either very low with subsequent increase or coincident with the present mode (“modal hypothesis”).
Journal ArticleDOI
A phylogenetic study of bird karyotypes.
Nobuo Takagi,Motomichi Sasaki +1 more
TL;DR: A major role had been played by centric fission as well as fusion, translocation, and pericentric inversion in birds to elucidate mechanisms involved in certain structural changes of macrochromosomes observed in birds.

Autosomal polymorphism in laboratory bred and wild Norway rats, Rattus norvegicus, found in Misima
Tosihide H. Yosida,Kôhachi Amano +1 more
TL;DR: Polymorphism in chromosome pair no. 3 of Rattus norvegicus was found in laboratory strains and wild rats, and in inbred strains were classified into two types concerning the pairNo.
Journal ArticleDOI
Comparative DNA values and chromosome complements of eight species of fishes.
TL;DR: The present study appears to indicate that a series of polyploidization of the original vertebrate genome took place while vertebrates were still aquatic forms, and the polyphyletic evolution of terrestrial vertebrates is suggested.
