“…The brown rat (R. norvegicus), one of the most common commensal rats, draws substantial public health interest, acting as a reservoir for a number of zoonotic pathogens such as Hantavirus, and disseminating many diseases (Meerburg et al 2009;Kosoy et al 2015). It is well-recognized that the brown rat spread out of Asia to Europe (Silver 1941;Southern 1964;Freye and Thenius 1968;Amori and Cristaldi 1999;Kosoy et al 2015). This conclusion is supported by historical records (Suckow et al 2006) and genetic evidences from mitochondrial and nuclear markers (Song et al 2014;Puckett et al 2016).…”

The geographic origin and migration of the brown rat (Rattus norvegicus) remain subjects of considerable debate. In this study, we sequenced whole genomes of 110 wild brown rats with a diverse world-wide representation. We reveal that brown rats migrated out of southern East Asia, rather than northern Asia as formerly suggested, into the Middle East and then to Europe and Africa, thousands of years ago. Comparison of genomes from different geographical populations reveals that many genes involved in the immune system experienced positive selection in the wild brown rat.

“…Ancestral populations of R. tanezumi were distributed from Southeast Asia to Yunnan of China (Guo et al, 2019), whereas ancestral populations of R. norvegicus were distributed from Inner Mongolia to northern China (Allen, 1940; Puckett et al, 2020; Silver, 1941; Wilson & Reeder, 2005). Before large‐scale expansion with human shipping transportations, the demographic histories of the two species were closely related to climate changes.…”

“…In addition, R. norvegicus is another dominant house rat species in China (Wang, 2003). Some studies proposed that R. norvegicus originated in southeast Asia (Zeng et al, 2017), but a recent investigation using genome data (Puckett & Munshi-South, 2019) supported the long-time consideration that R. norvegicus originated in northern China and Mongolia (Allen, 1940;Silver, 1941;Wilson & Reeder, 2005). From its natal range, this species migrated to southeast Asia and coastal ports and then expanded into the Middle East and Europe, and subsequently invaded western Africa, eastern North America, South America, and New Zealand; furthermore, this species also expanded eastward into Russia and finally to western North America (Puckett et al, 2016(Puckett et al, , 2020Puckett & Munshi-South, 2019;Russell et al, 2019).…”

Rattus norvegicus and Rattus tanezumi are dominant species of Chinese house rats, but the colonization and demographic history of two species in China have not been thoroughly explored. Phylogenetic analyses with mitochondrial DNA including 486 individuals from 31 localities revealed that R. norvegicus is widely distributed in China, R. tanezumi is mainly distributed in southern China with currently invading northward; northeast China was the natal region of R. norvegicus , while the spread of R. tanezumi in China most likely started from the southeast coast. A total of 123 individuals from 18 localities were subjected to 2b‐RAD analyses. In neighbor‐joining tree, individuals of R. tanezumi grouped into geographic‐specific branches, and populations from southeast coast were ancestral groups, which confirmed the colonization route from southeast coast to central and western China. However, individuals of R. norvegicus were generally grouped into two clusters instead of geographic‐specific branches. One cluster comprised inland populations, and another cluster included both southeast coast and inland populations, which indicated that spread history of R. norvegicus in China was complex; in addition to on‐land colonization, shipping transportation also have played great roles. ADMIXTURE and principal component analyses provided further supports for the colonization history. Demographic analyses revealed that climate changes at ~40,000 to 18,000 years ago and ~4000 years ago had led to population declines of both species; the R. norvegicus declined rapidly while the population of R. tanezumi continuously expanded since ~1500 years ago, indicating the importance of interspecies' competition in their population size changes. Our study provided a valuable framework for further investigation on phylogeography of two species in China.

The brown rat (Rattus norvegicus) is found wherever humans live and transmits many diseases, and its breeding produced the laboratory rat used widely in medical research.Here, we sequenced whole genomes from 118 rats to explore the origin and dispersal routes of the brown rat and the domestication of the laboratory rat. We showed that brown rats migrated about 3600 years ago from southern East Asia, rather than Northern Asia as formerly suggested, to the Middle East and then to Europe and Africa. Many genes involved in the immune system experienced positive selection in the wild brown rat, while genes involved in the nervous system and energy metabolism showed evidence of artificial selection during the domestication of laboratory strains. Our findings demystify the puzzling origin and migration of brown rats and reveal the impact of evolution and domestication on this animal.
