“…Fifty-seven different auto- Nguyen et al [2008], in their phylogenetic analysis of chromosomal data, suggest that the placement of the saola (Pseudoryx nghetinhensis) should be within the subtribe Bubalina, which contains the species of the Bubalus and Syncerus genera. Chromosome homologies between Damaliscus lunatus and M. reevesi have been established by cross-species painting with Chinese muntjac chromosome paints [Huang et al, 2011]. The chromosomal rearrangements were consistent with published phylogenies based on morphology.…”

Cetartiodactyla comprises Artiodactyla (even-toed ungulates) and Cetacea (whales, dolphins and porpoises). Artiodactyla is a large taxon represented by about 200 living species ranked in 10 families. Cetacea are classified into 13 families with almost 80 species. Many publications concerning karyotypic relationships in Cetartiodactyla have been published in previous decades. Formerly, the karyotypes of closely related species were compared by chromosome banding. Introduction of molecular cytogenetic methods facilitated comparative mapping between species with highly rearranged karyotypes and distantly related species. Such information is a prerequisite for the understanding of karyotypic phylogeny and the reconstruction of the karyotypes of common ancestors. This study summarizes the data on chromosome evolution in Cetartiodactyla, mainly derived from molecular cytogenetic studies. Traditionally, phylogenetic relationships of most groups have been estimated using morphological data. However, the results of some molecular studies of mammalian phylogeny are discordant with traditional conceptions of phylogeny. Cetartiodactyls provide several examples of incongruence between traditional morphological and molecular data. Such cases of conflict include the relationships of the major clades of artiodactyls, the relationships among the extant families of the suborder Ruminantia or the phylogeny of the family Bovidae. The most unexpected aspect of the molecular phylogeny was the recognition that Cetacea is a deeply nested member of Artiodactyla. The largest living order of terrestrial hoofed mammals is the even-toed hoofed mammals, or Artiodactyla. The artiodactyls are composed of over 190 living species including pigs, peccaries, hippos, camels, llamas, deer, pronghorns, giraffes, sheep, goats, cattle and antelopes. Cetacea is an order of wholly aquatic mammals, which include whales, dolphins and porpoises. Cetartiodactyla has become the generally accepted name for the clade containing both of these orders.

Robertsonian (Rb) translocations, in particular centric fusions, are thought to play a primary role in evolution and speciation of the Bovidae family. However, Rb fusions are often polymorphic within species, being suggested as phylogenetically uninformative characters. This work studies chromosome variation in 72 captive individuals of 6 species of Alcelaphini (Antilopinae): The hartebeest (genus Alcelaphus), hirola (Beatragus), black and blue wildebeests (Connochaetes), and the topi and bontebok (Damaliscus). We infer the phylogenic relationships among Alcelaphini species and determine patterns of chromosomal evolution using G-banded karyotypes and complete mitochondrial genome sequences. The molecular phylogeny showed an early divergence of Connochaetes, followed by the split of Alcelaphus plus Beatragus + Damaliscus as sister taxa. Mitochondrial and chromosomal phylogenies only differed in the position of the critically endangered Beatragus, likely due to homoplasic chromosome characters. Patterns of chromosome evolution, reconstructed using a probabilistic approach, suggest that chromosome changes leading to speciation in Alcelaphini do not exclusively involve consecutive reduction of diploid number through centric fusion but also the losses and reversions of Rb translocations in Beatragus and Damaliscus lineages. Our results provide evidence that complex scenarios of chromosomal rearrangements can be detected in relatively recent-diverged bovids, as in this group of antelopes.
