India–Somalia and North America–Eurasia relative motions since Early Miocene ( 20 Ma) have been recently reconstructed at unprecedented temporal resolution (o1 Myr) from magnetic surveys of the Carlsberg and northern Mid-Atlantic Ridges. These new datasets revamped interest in the convergence of India relative to Eurasia, which is obtained from the India–Somalia–Nubia–North America–Eurasia kine...
Global Positioning System (GPS) measurements in China indicate that crustal shortening accommodates most of India's penetration into Eurasia. Deformation within the Tibetan Plateau and its margins, the Himalaya, the Altyn Tagh, and the Qilian Shan, absorbs more than 90% of the relative motion between the Indian and Eurasian plates. Internal shortening of the Tibetan plateau itself accounts for ...
Observed and reconstructed snow-cover duration data from stat ions covering southern Canada, the Great Plains, the former Soviet Union and China were used to reconstruct spring snow-covered area over North America (NA) and Eurasia from 1915 to 1985. A combination o[nine regions from NA and five from Euras ia were able to explain 81 % and 67%, respectively, of the variance in satellite-derived s...
Mitochondrial DNA (mtDNA) sequences from 686 wild and domestic pig specimens place the origin of wild boar in island Southeast Asia (ISEA), where they dispersed across Eurasia. Previous morphological and genetic evidence suggested pig domestication took place in a limited number of locations (principally the Near East and Far East). In contrast, new genetic data reveal multiple centers of domes...
It has become important to answer the questions of what energy related infrastructure, such as transcontinental natural gas pipelines and international electricity grids, should be constructed in Asia/Eurasia, and how energy demand should be satisfied there securely, economically, and environmentally benignly over the next several decades. The purpose of this study is to investigate the possibl...
The early Pleistocene colonization of temperate Eurasia by Homo erectus was not only a significant biogeographic event but also a major evolutionary threshold. Dmanisi's rich collection of hominin fossils, revealing a population that was small-brained with both primitive and derived skeletal traits, has been dated to the earliest Upper Matuyama chron (ca. 1.77 Ma). Here we present archaeologica...
Africa is commonly marginalized in global social studies, whether of present or past. This essay makes the case for the substantial importance of Africa through a systematic comparison with Eurasia. It documents the large area and the relatively dense population of Africa, in past and present, as compared with Eurasia and also with the Americas. The essay gives particular attention both to sub-...
Currently, the Northern Eurasia Earth Science Partnership Initiative (NEESPI) includes over 120 international projects involving more than 200 scientific institutions from over 30 countries. The program involves national government agencies, academia and private organizations in the U.S., Europe, Japan and Northern Eurasia (Gutman 2007). The NEESPI science is directed at evaluating the role of ...
A key to understanding the complex pattern of hominoid dispersals, origins, and extinction is the fossil evidence from Turkey. Miocene localities in Turkey are known to contain taxa from across Eurasia and Africa, and even North America. Three or four separate hominoid clades are identified in Anatolia, more than in any other place except Kenya. Each of these clades has its closest affinities w...
