The mitochondrial DNA (mtDNA) control region and flanking tRNAs were sequenced from 76 mice collected at 60 localities extending from Egypt through Turkey, Yemen, Iran, Afghanistan, Pakistan, and Nepal to eastern Asia. Segments of the Y chromosome and of a processed p53 pseudogene (Psip53) were amplified from many of these mice and from others collected elsewhere in Eurasia and North Africa. Th...

Engelswies is an early Miocene vertebrate locality in southern Germany with a rich assemblage of terrestrial mammals, invertebrates and fossil plants. It is dated to 16.5-17.0 Ma based on magnetostratigraphy, biostratigraphy and lithostratigraphy, and includes among the faunal remains a hominoid upper molar fragment, the oldest hominoid so far identified from Europe. The evidence from Engelswie...

Although there is a general consensus on African origin of early modern humans, there is disagreement about how and when they dispersed to Eurasia. This paper reviews genetic and Middle Stone Age/Middle Paleolithic archaeological literature from northeast Africa, Arabia, and the Levant to assess the timing and geographic backgrounds of Upper Pleistocene human colonization of Eurasia. At the cen...

Recent hunter-gatherers display much uniformity in the division of labor along the lines of gender and age. The complementary economic roles for men and women typical of ethnographically documented hunter-gatherers did not appear in Eurasia until the beginning of the Upper Paleolithic. The rich archaeological record of Middle Paleolithic cultures in Eurasia suggests that earlier hominins pursue...

Abstract We present two robust and well‐dated paleomagnetic poles from upper Eocene Oligocene volcanics in the Urumieh‐Dokhtar magmatic arc, Central Iran. These place Iran ∼3.7°–3° of latitude south its position between ca. 40 23 Ma. Our new declination data indicate that block may have experienced a ∼11.6° clockwise rotation since Late Eocene. integrated our with retrodeformed margins Zagros c...

China-Russia strategic partnership has evolved into a new stage where the two great powers share increasing overlapping and complementary interests. The Greater Eurasia Partnership (GEP) framework offers an integrated approach to conducting their relations by deepening collaborative partnerships through regional development security cooperation. This article aims analyze evolving nature of GEP ...

We have investigated the performance of a variety of travel time computation methods for application in highly heterogeneous three-dimensional (3-D) velocity structures, such as those found in Central Eurasia. Recent 3-D models of the crust and upper mantle beneath Central Eurasia (e.g., Villaseñor et al., 2000) contain sharp vertical and horizontal velocity contrasts and thin layers which comp...

Resumen.—Muchas especies de playeros tienen distribuciones amplias que incluyen continentes diferentes. Debido a que los playeros son excelentes voladores y tienen la capacidad de migrar largas distancias, muchas veces no está claro si existen barreras reproductivas entre poblaciones o subespecies de diferentes continentes. Charadrius alexandrinus es una especie cosmopolita. Hace mucho tiempo s...
