The domestic dog fulfills many functions for their human companions, such as hauling, guarding, and protection. Consequently, humans have taken dogs to nearly every corner of the globe. Recent translocations of Western dogs stemming from the Victorian era dog fancy have erased some of the ancient genetic signatures of these earlier migrations. Here we used DNA of ancient and modern dogs from the North American Arctic of Alaska and Greenland to assess their genetic continuity in time and space. We successfully sequenced 23 archaeological (ca. AD 1250–1910) and recent (ca. AD 1930–1990) surface-collected Canis bone and tooth samples and compared them to 51 modern Inuit Sled Dogs and to published sequences of modern Alaskan Malamutes (and additional Inuit Sled Dogs) to test for evidence of lineage replacement or genetic continuity through time. Ancient samples from Alaska and Greenland and modern sequences from Greenland all contained a high frequency of haplotype A31, which was previously described only in modern North American Arctic dogs. Thus, A31 was a common thread tying the entire North American Arctic together prior to European colonization and, in the Eastern Arctic, indicates genetic continuity between past and present dogs as well. However, A31 is rare in modern Alaskan dogs, consistent with post-colonization replacement by Eurasian matrilines. 相似文献

My essay focuses on the relation between consciousness and reality. I argue, following Georg Cantor, that consciousness is a potential infinite driven by care to invest itself in the world historically. As human beings develop an authentic sense of self they are driven by good faith to postulate an Absolute infinite, which, following Spinoza, we may call God. Thus God, as the Absolute infinite, constitutes our reality, which I characterize as implicate information explicating itself through time. To live authentically is to recognize the nature of God and commit to Him through faith. Faith means to understand one’s self as a potentially infinite consciousness attempting to authentically participate in, and understand, the Absolute of God. 相似文献

Matthew G Hannah 《Social & Cultural Geography》2016,17(1):71-80
This commentary will coalesce around two main points. First, the articles by Markus Hesse on urban geography, by Annika Mattissek and Georg Glasze on recent developments in discourse-analytic approaches, and by Ulrich Best on the genealogy of radical–Marxist or critical German-language geography all support the contention that key features of Germanophone human geography still mark it out as a ‘Cold War’ human geography. As will become clear, this contention goes well beyond noting the marginality (until recently) of radical–Marxist positions (Belina, B., Best, U., & Naumann, M. (2009). Critical geography in Germany: From exclusion to inclusion via internationalization. Social Geography, 4, 47–58). Second, I will argue that although this configuration has had real costs, including both analytic and ‘civic’ deficits, it has also allowed the development of distinctive strengths and innovative emphases in human geographic research that can and should be engaged by other sub-communities in the international discourse. 相似文献
