Little has been known about the impacts of past vicariance events on the phylogeography and population structure of freshwater fishes in East Asia. The aims of this study are to assess the genetic variability with extensive sampling throughout the range of Chinese spiny loach, Cobitis sinensis, and to infer the genetic structure and evolutionary history of populations. Cobitis sinensis in China may have initiated from two ancestral populations, namely Yangtze and Pearl Rivers, which diverged about 7.24 MYA likely due to drainage systems alteration. In the phylogroup I, a southward dispersal event occurred from East China (Yangtze River) to south ZheMin and Hainan subregions, followed by eastward dispersal from ZheMin to south Taiwan. In the phylogroup II, eastward colonization took place from Pearl River to north Taiwan in the late Pliocene, coupled with loss of genetic diversity in the island populations. This study showed that Cenozoic tectonic movements and climatic and sea‐level fluctuations may have shaped the genetic structure of C. sinensis in concert. Highly diverged mtDNA sequences suggest existence of cryptic species in morphospecies C. sinensis.

The rapid development of molecular phylogenetic analysis has provided a new path to investigate the tempo of evolution. In this work, a rather complete molecular phylogeny of the East Asian gobionid fishes was constructed based on mtDNA cytochrome b gene sequences. Molecular clock analysis was then applied to investigate the speciation tempo of this group. The phylogenetic analysis revealed four major groups that were in agreement with previous studies. Lineage numbers plotted over time indicate that gobionid lineages increased in an exponential mode with the equation expressed as y = 87.562×e It is estimated that a total of 3−5 million species exist on the earth [1]. Even more species are now extinct. How do these species evolve on the geological time scale? Do new species appear at a constant rate, or does the speciation rate vary in some regular way? These questions have been the major focuses of evolutionary biology for centuries [2]. Traditionally, the tempo of speciation must be tackled by fossil record, while biological study based on extant species can only deal with the "static" problem. However, recent development of molecular systematics has supplied a new path to analyze the tempo of evolution [3,4]. Calibrated by the fossil record, molecular phylogenetic trees can provide information about the relative timing of reconstructed speciation events [5−8], and can be used to estimate speciation rates [9]. Based on the information from molecular phylogenetic trees, the evolutionary mode, and relationships between evolution and environmental conditions can be postulated. For example, Megens et al.[10] suggested large-scale climatic changes taking place in the Miocene had induced the early acceleration of speciation in the butterfly genus Arhopala.Within the past decade, the dramatic development of molecular systematics allows the use of DNA sequence analysis to hypothesize evolutionary relationships among taxa. Meanwhile, hypotheses, models, and methods for analysis of speciation rates have been proposed by various authors. Particularly different software for this analysis has been developed [11]. It can be anticipated that study on speciation tempo will be conducted in many groups and some general conclusions will be drawn in the near future.East Asia contains several highly biodiverse hotspots. Molecular phylogenetic analysis has been conducted on East Asian plants [12], insects [13], fishes [14,15], amphibians [16] and mammals [17,18], etc. These studies revealed the phylogenetic relationships of these groups, proposed their evolutionary scenarios in geological time scale, and

Multiple in-to-Africa dispersals of labeonin fishes (Teleostei: Cyprinidae) revealed by molecular phylogenetic analysis

An out-of-Africa dispersal route has been proposed for many organisms, including modern man. However, counter examples of in-to-Africa dispersal routes are less common. In the present article, the phylogenetic relationships within the Labeoninae, a subfamily of cyprinid fishes distributed in Asia and Africa, were analyzed to investigate the biogeographic processes governing the modern distribution of these Asian and African cyprinids. The mitochondrial DNA cytochrome b gene was used as a molecular marker. The phylogenetic analysis indicated that the subfamily Labeoninae is a monophyletic group, with some Asian labeonins located at the basal position. Two subclades were found that contained both African and Asian species, which highlighted a need for further biogeographic analysis. Based on this analysis, it is proposed that the centre of origin of the Labeoninae was in East Asia. Molecular clock estimation suggests that the Labeoninae arose by the Early Miocene (*23 MYA) during the period of the second Tibetan uplift.Subsequently, two dispersal events of labeonins from Asia into Africa occured in the Early Miocene (* 20 MYA) and Late Miocene (*9 MYA) and serve as examples counter to out-of-Africa dispersal.
