The domestication of swamp buffalo (Bubalus bubalis carabanesis) has been discussed for years and still remained unclear. To obtain a better understanding of where, when and how the swamp buffaloes were domesticated, the complete mitochondrial DNA D-loop sequences of 1,788 individuals from China, Vietnam, Laos, Thailand, Burma, Bangladesh and India were investigated. Our results revealed swamp buffalo with abundant genetic diversity. The lineage SA of swamp buffalo may be first domesticated in Lower Yangtze and then migrated following two different routes: one migrated along the Upper Yangtze to Southwest China (L1); the other migrated to Southeast China to Southeast Asia through Guangxi province (L2). During the migration process several later domestication events may be inspired in the Upper Yangtze (SB3), Southwest China and North of Southeast Asia (SB1 and SB2). In this study, we proposed a non-independent multiple domestication pattern in swamp buffalo.
