Figure 1. A in Evolutionary History of the Subgenus Mus in Eurasia with Special Emphasis on the House Mouse Mus musculus
Figure 1. A sketch of the evolutionary patterns of lineage differentiation among species in the genus Mus based on molecular phylogenetic analysis of nuclear gene sequences (Suzuki et al., 2004; Shimada et al., 2010). The tree shows the four subgenera of the genus Mus and the four species groups (SGs) of the subgenus Mus: M. musculus, M. booduga, M. lepidoides, and M. caroli (previously termed as M. cervicolor SG), representing four geographic regions of the Palaearctic region, Indian subcontinent, Myanmar, and Southeast Asia, respectively. The taxon previously regarded as "M. cervicolor" in Thailand is here referred to as "M. sp.", due to uncertainty regarding the taxonomic status of the sampled specimens (see main text). The estimated divergence times for the subgenera and species groups are approximately 5 and 2.5 million years ago, respectively (Shimada et al., 2010). Specific habitat transitions from grasslands to forests and arid areas are marked for the species lineages of M. cookii and M. lepidoides. Predicted dispersal events between geographic regions are indicated with dotted arrows.
Figures 2–4 in Evolutionary History of the Subgenus Mus in Eurasia with Special Emphasis on the House Mouse Mus musculus
Figures 2–4. Assessment of population genetic structure using concatenated sequences (4302 bp) of seven nuclear genes. (2) Positions of the analysed regions (open triangles) in seven genes on murine chromosome 8 (Nunome et al., 2010; Kodama et al., 2013). (3) Neighbour- Net network based on concatenated sequences from 98 Mus musculus, showing haplogroups representing the subspecies groups Mus musculus domesticus (DOM), Mus musculus castaneus (CAS), and Mus musculus musculus (MUS) as well as recombinant haplotypes (Re) (Kodama et al., 2013). In the network, the level of diversity of CAS is markedly higher than those of DOM and MUS, yielding five distinct phylogroups A–E. Scale bar indicates genetic divergence. (4) Approximate geographic ranges of the five subclusters of CAS. Localities where samples used in this analysis were collected are marked with open and filled circles, representing the mitochondrial haplogroup CAS-1 and all other types, respectively (Kodama et al., 2013). The phylogroups A–E of CAS showed rough geographical distributions and one of them, phylogroup D, comprised the haplotypes recovered from a large geographical area of Southeast Asia, south China, and Indonesia and can be characterized as the lineage dispersed with prehistoric human movement (arrow; Kodama et al., 2015). Note that subcluster D (arrow in Fig. 3) shows a broad distribution range in Southeast Asia and the southern part of East Asia. In the Neighbor-Net network, this subcluster exhibits limited divergence among haplotypes.
House mouse Mus musculus dispersal in East Eurasia inferred from 98 newly determined complete mitochondrial genome sequences
<div> <p><span><span><span><span><span><span><span><span><span><span><span>The Eurasianhouse mouse <i>Mus musculus</i>is useful for tracing prehistorical human movement related to the spread of farming. We determined whole mitochondrial DNA (mtDNA) sequences (ca. 16,000 bp) of 98 wild-derived individuals of two subspecies, <i>M</i>. <i>m</i>. <i>musculus </i>(MUS) and <i>M</i>. <i>m</i>. <i>castaneus </i>(CAS). We revealed directional dispersals reaching as far asthe Japanese Archipelagofrom their homelands. Our phylogenetic analysis indicated that the eastward movement of MUS was characterised by five step-wise regional extension events: 1) broad spatial expansion into eastern Europe and the western part of western China, 2) dispersal to the eastern part of western China, 3) dispersal tonorthern China, 4) dispersal to the Korean Peninsula and 5) colonisation and expansion in the Japanese Archipelago. These events were estimated to have occurred during the last 2,000–18,000 years. The dispersal of CAS was characterised by three events: initial divergences(ca. 7,000–9,000 years ago) of haplogroups in northern most China and the eastern coast of India, followed by two population expansion events that likely originated from the Yangtze River basinto broad areas of South and Southeast Asia, including Sri Lanka, Bangladesh and Indonesia (ca. 4,000–6,000 years ago) and to Yunnan, southern China and the Japanese Archipelago (ca. 2,000–3,500). This study provides a solid framework for the spatiotemporal movementof the human-associated organisms in Holocene Eastern Eurasia using whole mtDNA sequences, reliable evolutionary rates and accurate branching patterns. The information obtained here contributes to the analysis of a variety of animals and plants associated with prehistoric human migration.</span></span></span></span></span></span></span></span></span></span></span></p> </div>

Resolution of the house mouse (Mus musculus) phylogeny by integration over isolation-with-migration histories
The three main subspecies of house mice, Mus musculus castaneus, Mus musculus domesticus , and Mus musculus musculus, are estimated to have diverged ~325-500KYA. Resolution of the details of their evolutionary history is complicated by their relatively recent divergence, ongoing gene flow among the subspecies, and complex demographic histories. Previous studies have been limited to some extent by the number of loci surveyed and/or by the scope of the method used. Here we apply a method (IMa3) that provides an estimate of a population phylogeny while allowing for complex histories of gene exchange. Results strongly support a topology with M. m. domesticus as sister to M. m. castaneus and M. m. musculus . In addition, we find significant evidence of reciprocal gene flow between all pairs of subspecies. Our estimates of another key set of parameters, effective population size ( N e ), support previous results that the N e of M. m. castaneus is larger than that of the other two subspecies.
