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 (similar to 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 (similar to 20 MYA) and Late Miocene (similar to 9 MYA) and serve as examples counter to out-of-Africa dispersal.

This study aims to present the conditions related to the European Union’s involvement in the Arab Spring, as well as examine the extent of this capability-based involvement in the first months of 2011 against the background of competence disputes between institutions and inter-governmental contentions. These considerations will be the basis for conclusions on the theoretical and practical viability of the European Union’s action in the region of North Africa, in terms of both interests defined in Brussels and representation of a jointly agreed position and undertaking practical actions in the international arena. These assumptions can facilitate a new perspective for the EU’s strategic approach framework in the region of North Africa.
