From Africa to Eurasia * Early Dispersals Ofer Bar-Yosef! *, A
Quaternary International 75 (2001) 19}28 From Africa to Eurasia * early dispersals Ofer Bar-Yosef! *, A. Belfer-Cohen" !Department of Anthropology, Peabody Museum, Harvard University, Cambridge, MA 02138, USA "Institute of Archaeology, Hebrew University, Jerusalem 91905, Israel Abstract The dispersals of early hominins in the late Pliocene or early Pleistocene into Eurasia were essentially sporadic. Little geographic and temporal continuity is observed between the various dated archaeological contexts, and the lithic assemblages do not demonstrate a techno-morphological continuity. The archaeological evidence from 1.8 to 0.7 Ma indicates at least three waves of early migrations. The earliest sortie involved bearers of core-chopper industries sometime around 1.7}1.6 Ma. Early Acheulean producers followed possibly around 1.4 Ma. The third wave occurred sometime around 0.8 Ma, and is represented by Acheulean groups who manufactured numerous #ake cleavers. The geographic scope of each of these waves is not yet well known.The reasons for &why' early humans dispersed from Africa into Eurasia include the &push' of environmental change and relative &demographic pressure', as well as the opening of new niches. Humans may have gained their meat supplies either from carcasses or through active predation. The archaeological and fossil records demonstrate that Homo erectus was a successful species, and like other successful species it enlarged its geographic distribution at all costs. Even if the trigger for the initial dispersal of Homo erectus remains unknown or controversial, the success of the hominid occupation of the Eurasian habitats was not primarily facilitated by the availability of food, or the human #exibility in food procuring techniques, but by the absence of the zoonotic diseases that plagued and constrained hominins in their African &cradle of evolution'. -

The highest crude death rates in the world are found among the transition countries; so too the lowest fertility rates. This study analyzes these trends and attempts to assess some of the underlying health factors behind them. The report also examines the evidence regarding migration patterns, both political aspects (including trends in refugees and internally displaced persons) and economic aspects (including remittances, urbanization, and brain drain). 2 USAID/E&E/PO Working Paper Series on the Transition Countries September 2006 No.1 Demography and Health (June 2005) No.2 Education (October 2005) No.3 Economic Reforms, Democracy, and Growth (November 2005) No.4 Monitoring Country Progress in 2006 (September 2006) No.5 Domestic Disparities (forthcoming) No.6 Labor Markets (forthcoming) No.7 Global Economic Integration (forthcoming) The findings, interpretations, and conclusions expressed in these working papers are entirely those of the authors. -
Russia and Eurasia Steven Pifer
14 Russia and Eurasia Steven Pifer Russia for the past 4 years has been on an economic roll fueled by high energy prices. The Kremlin in parallel has pursued an increasingly assertive foreign policy, raising the prospect of a more contentious Russia that will challenge U.S. interests in the former Soviet space, Europe, and elsewhere. The challenges posed by a more assertive Russia will command greater time and attention from U.S. national security planners. It is not only a resurgent Russia that could test the United States in coming years, however. A frail, unstable Russian state is not in the U.S. interest. Russian weakness raises less obvious, but nevertheless serious, possible challenges. Demographic, societal, and economic trends within Russia have the potential, particularly in combination, to create strategic shocks over the next 10 to 30 years that would have major implications for U.S. national security interests. This chapter examines those trends and potential shocks and outlines implications for U.S. national security. The strategic shocks that trends within Russia could combine to produce include collapse of the Russian state, expansion to take in more ethnic Russians, revolution (leading to a lurch toward democracy or, more likely, to the right), playing the energy card, and a military/technical surprise. While these shocks each have a very low likelihood, any of them would pose critical implications and challenges for key U.S. security interests. This chapter also looks at possible shocks elsewhere in the former Soviet space: Islamic revolution in a Central Asian state and Georgian-Russian military conflict, with the latter being the most likely shock of those addressed. -

From a geographical perspective, it is considered a subcontinent of Asia.[3] It is the largest peninsula in the world, at 3,237,500 km2 (1,250,000 sq mi).[4][5][6][7][8] The peninsula consists of the countries Yemen, Oman, Qatar, Bahrain, Kuwait, Saudi Arabia and the United Arab Emirates.[9] The peninsula formed as a result of the rifting of the Red Sea between 56 and 23 million years ago, and is bordered by the Red Sea to the west and southwest, the Persian Gulf to the northeast, the Levant to the north and the Indian Ocean to the southeast. The peninsula plays a critical geopolitical role in the Arab world due to its vast reserves of oil and natural gas. The most populous cities on the Arabian Peninsula are Riyadh, Dubai, Jeddah, Abu Dhabi, Doha, Kuwait City, Sanaʽa, and Mecca. Before the modern era, it was divided into four distinct regions: Red Sea Coast (Tihamah), Central Plateau (Al-Yamama), Indian Ocean Coast (Hadhramaut) and Persian Gulf Coast (Al-Bahrain). -

The Tectonic History of the Banda Arcs, Eastern Indonesia: a Review
J. geol. Soc. London, Vol. 136, 1979, pp. 519-527,2 figs. Printed inNorthern Ireland. The tectonic history of the Banda Arcs, eastern Indonesia: a review M. S. Norvick SUMMARY: The Banda Sea is underlain by a small marginal oceanic plate, which is believed to have formed during the early Tertiary. Unlike other marginal seas to the N, the spreading of the Banda platelet was restricted by surrounding continental blocks. Its present complexity is a result of late Miocene-earlyPliocene collision and obduction of theBanda Sea island arc system over the leading edge of the Australian-lrian continental plate. Transcurrent faultingon the northern limb of the collision zone may have accentuated curvature of the arc. Subduction and volcanicitv ceased after collision in the Timor and Seram sectors, but are still active at the eastern extremity of the arc.
