Mus Musculus castaneus
Brenner's Encyclopedia of Genetics, 2013Co-Authors: François Bonhomme, Annie OrthAbstract:The House Mouse Mus Musculus is now seen as a polytypic species where three main branches have differentiated in isolation within the past 500 000 years and have come to contact again on several occasions. It is almost invariably considered as being constituted of three subspecies, Mus Musculus castaneus being considered as more polymorphic, with a larger effective population size and as having retained more ancestral polymorphisms than the other two. Yet, it is the less, well-studied component, and its geographical origin and genetic makeup disserve more careful attention since a recent reappraisal was indeed shown that the House Mouse populations in the region ranging from Middle-East to Southeast Asia classically assigned to M. m. castaneus are indeed much more diverse than previously thought. Since the House Mouse is often taken as a model species, this may have important bearings on our understanding of the context in which genome evolution and speciation occurs.

The south-eastern house mouse Mus Musculus castaneus (Rodentia: Muridae) is a polytypic subspecies
Biological Journal of the Linnean Society, 2012Co-Authors: Hassan Rajabi-maham, Annie Orth, Pierre Boursot, Roohollah Siahsarvie, Jamshid Darvish, François BonhommeAbstract:Accurate knowledge of the biogeographic history and precise characterization of the genetic make-up of a taxon are essential to investigate speciation processes and achieve sound evolutionary comparisons. A case in point is the house mouse Mus Musculus and its three parapatric subspecies, which have become a model for such studies. However, although Mus Musculus domesticus and Mus Musculus Musculus constitute genetically wellcharacterized homogeneous entities, the case of Mus Musculus castaneus remains poorly documented. Using mtDNA control region variation in a sample of 402 individuals, covering much of the distribution range of this subspecies, we identify four haplogroups that show largely non-overlapping geographic distributions. They appear to have undergone post-Neolithic expansions, presumably through commensalism with humans, but exhibit a much more ancient divergence. These results point towards a strong past subdivision and a vicariant origin of the different haplogroups, with each retaining a subfraction of the total variability. The genomic consequences of this spatial heterogeneity on the present taxonomic partition will have to be appraised, and may challenge the use of this subspecies as a single entity in evolutionary studies.

patterns of morphological evolution in the mandible of the house mouse Mus Musculus rodentia muridae
Biological Journal of The Linnean Society, 2012Co-Authors: François Bonhomme, Roohollah Siahsarvie, Jeanchristophe Auffray, Jamshid Darvish, Hassan Rajabimaham, Sylvie Agret, Julien ClaudeAbstract:The worldwide distributed house mouse, Mus Musculus, is subdivided into at least three lineages, Mus Musculus Musculus, Mus Musculus domesticus, and Mus Musculus castaneus. The subspecies occur parapatrically in a region considered to be the cradle of the species in Southern Asia (‘central region’), as well as in the rest of the world (‘peripheral region’). The morphological evolution of this species in a phylogeographical context is studied using a landmark-based approach on mandible morphology of different populations of the three lineages. The morphological variation increases from central to peripheral regions at the population and subspecific levels, confirming a centrifugal sub-speciation within this species. Furthermore, the outgroup comparison with sister species suggests that M. Musculus Musculus and populations of all subspecies inhabiting the Iranian plateau have retained a more ancestral mandible morphology, suggesting that this region may represent one of the relevant places of the origin of the species. Mus Musculus castaneus, both from central and peripheral regions, is morphologically the most variable and divergent subspecies. Finally, the results obtained in the present study suggest that the independent evolution to commensalism in the three lineages is not accompanied by a convergence detectable on jaw morphology. © 2012 The Linnean Society of London, Biological Journal of the Linnean Society, 2012, 105, 635–647.
