Recent investigations of a limestone solution cave on the Queen Charlotte Islands (Haida Gwaii) have yielded skeletal remains of fauna including late Pleistocene and early Holocene bears, one specimen of which dates to ca. 14,400 14C yr B.P. This new fossil evidence sheds light on early postglacial environmental conditions in this archipelago, with implications for the timing of early human migration into the Americas.

<p>East Asia is a key area for early human migration and evolution in the Old World. During the early Pleistocene, humans began to spread out of Africa. Detailed magnetostratigraphic dating coupled with high-precision isotopic chronology of early humans in mainland East Asia, western and southeastern Asia has provided insights into our understanding of early human adaptability to a variety of environments in the eastern Old World. Before the Middle Pleistocene, early humans occupied over a broad latitudinal range, from temperate northern China (e.g., the Nihewan Basin and the Loess Plateau) to subtropical southern China (e.g., the Yuanmou Basin). Thus oldest recorded human dispersal to East Asia apparently culminated in the ability to adapt diverse environments. Around the Middle Pleistocene Climate Transition, when the climate of Earth underwent profound changes in the length and intensity of its glacial-interglacial cycles with the dominant periodicity of high-latitude climate oscillations changing from 41 kyr to 100 kyr, there is a prominent early human flourishing in the high northern latitudes of East Asia and geographic expansion from low, through middle, to high northern latitudes of the area. The improved ability to adjust to diverse environments for early humans could have benefited from the increasing variability of global, regional and local paleoclimates and paleoenvironments and from the innovation of diet, e.g., the use of animal tissues.</p>

Students of twentieth-century migration generally agree that in any analysis of human migration two essential questions must be answered: Who are the migrants? And why did they leave? The questions seem obvious, but as they relate to seventeenth-century emigration to the American colonies, they are difficult to answer with precision. The records cannot be expected to reveal much about the emigrants as persons because they were ordinary people. If they could write—and most could not—the seventeenth-century emigrants left few diaries or letters to aid those who would study their movements. In fact, it is a rather fortunate researcher who uncovers even the few basic facts of their lives in the parish registers of christenings, burials, and marriages.The task of identifying and reconstructing the thoughts and motives of such an anonymous body of people is therefore a formidable one. Those who have pursued the task, first in regard to the so-called “Puritan Hegira” of the 1630s to New England, have concerned themselves almost exclusively with the question of motivation, and have failed to consider who the emigrants were. Only in a recent study of East Anglian and Kentish emigration to Massachusetts Bay in 1637 has there been a systematic analysis of the ordinary settlers. Yet, no attempt has been made either to identify emigrants or to investigate motives behind several considerable movements to America from areas outside East Anglia and southeastern England, thereby to test the various emigration theses based exclusively on those models.

<p>The dynamic interaction between synoptic systems across the Iranian Plateau in West Asia has made this region highly sensitive to climate change.   Early human migration routes in the region from Africa to Eurasia are marked by Paleolithic sites and provide a unique opportunity to study the impact of climate variability on early human mobility and settlement. Preliminary results are based on δ<sup>18</sup>O and elemental time series from three stalagmites in central-northwest Iran with robust U-Th chronology over the last 450,00 years The data raise the possibility that the Iranian Plateau experienced several episodes of wet conditions during the Paleolithic period. This is in line with findings from a compilation of independent proxy records of lake sediment in northwest Iran and loess deposits in northeast Iran. The fluctuation of Mn abundance and δ<sup>18</sup>O values in these stalagmites correlate with the Greenland ice core record (NGRIP) and coincide with periods of high solar intensity in the northern hemisphere. These early results indicate wet conditions may have prevailed over the Iranian Plateau during marine isotope stages MIS5a,b, MIS5c, MIS5e, MIS6b, MIS6d-e and most likely also during stages MIS3-4 and MIS7a. Early human occupation of the Southern Caucasus, Zagros, and the Near East regions coincides with the upper Pleistocene wet periods. The co-variability between the proxy data from these speleothems and solar insolation at 30°N suggests that early human settlements/occupations may have been more prevalent along coastal regions of the Near East during dry climate episodes.</p>
