“…Previous research has suggested that Muntiacus reevesi is the more primitive species within the Muntiacini [79,80]. Chromosome fusion and fusion were considered to be the major chromosomal evolutionary events of Muntiacini [79,81,82]. However, our study found a specific fusion of Muntiacus reevesi (BTA29 and BTA16 → RTA26 and RTA9 → CNI28 and CNI13 → CELY29 and CELY14 → CCA29 and CCA3 → CEL2 and CEL14→ MRE5 → MMU1 and MMU3X) (Table S11).…”

Cervidae represents a family that is not only rich in species diversity but also exhibits a wide range of karyotypes. The controversies regarding the phylogeny and classification of Cervidae still persist. The flourishing development of the genomic era has made it possible to address these issues at the genomic level. Here, the genomes of nine species were used to explore the phylogeny and chromosomal evolutionary events of Cervidae. By conducting whole-genome comparisons, we identified single-copy orthologous genes across the nine species and constructed a phylogenetic tree based on the single-copy orthologous genes sequences, providing new insights into the phylogeny of Cervidae, particularly the phylogenetic relationship among sika deer, red deer, wapiti and Tarim red deer. Gene family analysis revealed contractions in the olfactory receptor gene family and expansions in the histone gene family across eight Cervidae species. Furthermore, synteny analysis was used to explore the chromosomal evolutionary events of Cervidae species, revealing six chromosomal fissions during the evolutionary process from Bovidae to Cervidae. Notably, specific chromosomal fusion events were found in four species of Cervus, and a unique chromosomal fusion event was identified in Muntiacus reevesi. Our study further completed the phylogenetic relationship within the Cervidae and demonstrated the feasibility of inferring species phylogeny at the whole-genome level. Additionally, our findings on gene family evolution and the chromosomal evolutionary events in eight Cervidae species lay a foundation for comprehensive research of the evolution of Cervidae.

“…Despite exceptions at the microlinearity level (often also TE caused) (10), the general phenomenon of synteny is so well established that reliable predictions can be made even for species and genera of a plant or animal family that have not yet been analyzed (34,39,47,117). The chromosomes of man, cattle, and muntjac, even with the many chromosome reshufflings mentioned above, still display extensive homoeologies (46,151). However, in plants as distinct as rice (monocot) and Arabidopsis (dicot), so far synteny appears to be hardly detectable (34,35,88,117).…”

There has been limited corroboration to date for McClintock's vision of gene regulation by transposable elements (TEs), although her proposition on the origin of species by TE-induced complex chromosome reorganizations in combination with gene mutations, i.e., the involvement of both factors in relatively sudden formations of species in many plant and animal genera, has been more promising. Moreover, resolution is in sight for several seemingly contradictory phenomena such as the endless reshuffling of chromosome structures and gene sequences versus synteny and the constancy of living fossils (or stasis in general). Recent wide-ranging investigations have confirmed and enlarged the number of earlier cases of TE target site selection (hot spots for TE integration), implying preestablished rather than accidental chromosome rearrangements for nonhomologous recombination of host DNA. The possibility of a partly predetermined generation of biodiversity and new species is discussed. The views of several leading transposon experts on the rather abrupt origin of new species have not been synthesized into the macroevolutionary theory of the punctuated equilibrium school of paleontology inferred from thoroughly consistent features of the fossil record.
