It is necessary to predict them based on divergence estimates of different species. Here, there are some fragmentary samples from closely related species that difficult to be identified only using comparative morphology for divergence analyzing directly. Hence, both the standard COI barcode and Cytb gene are applied to calculate the K2P genetic distances and neighbor-joining (NJ) trees to distinguish species, and to execute maximum likelihood (ML) and Bayesian inferences for estimating recent divergence of extant Glires species constrained with a set of eight fossils in Xinjiang, China. The results show that DNA barcoding has identified these samples, with the exceptions of several sequenced species. Moreover, cryptic species may exist in Allactaga and Dipus, and the massive speciation events emerged during the Middle and the Late Miocene. This study infers that the evolutionary trends and faunal exchanges may be associated with the final India-Asia continental collisions and Tethys Sea retreated from the Tarim Basin around the Eocene-the Oligocene boundary as well as global climate fluctuations during the Miocene. Furthermore, the aridification and the changes of Taklimakan and Gurbantunggut Deserts might drive the diversification of subspecies, divergences of geographical populations and the emergences of cryptic species since the Late Pleistocene.} }
