The ancient Egyptians mummified an abundance of cats during the Late Period (664 - 332 BC). The overlapping morphology and sizes of developing wildcats and domestic cats confounds the identity of mummified cat species. Genetic analyses should support mummy identification and was conducted on two long bones and a mandible of three cats that were mummified by the ancient Egyptians. The mummy DNA was extracted in a dedicated ancient DNA laboratory at the University of California - Davis, then directly sequencing between 246 and 402 bp of the mtDNA control region from each bone. When compared to a dataset of wildcats (Felis silvestris silvestris, F. s. tristrami, and F. chaus) as well as a previously published worldwide dataset of modern domestic cat samples, including Egypt, the DNA evidence suggests the three mummies represent common contemporary domestic cat mitotypes prevalent in modern Egypt and the Middle East. Divergence estimates date the origin of the mummies' mitotypes to between two and 7.5 thousand years prior to their mummification, likely prior to or during Egyptian Predyanstic and Early Dynastic Periods. These data are the first genetic evidence supporting that the ancient Egyptians used domesticated cats, F. s. catus, for votive mummies, and likely implies cats were domesticated prior to extensive mummification of cats.  相似文献

The irreducible complexity and singular unpredictability of the upheavals that have roiled the Middle East since December 2010 challenge analysts—from university students to policymakers—to grapple with irresolvable questions; this, rather than analysts' superimposing their own visions of what might constitute the upheavals' driving forces, and what will, or should be the outcomes of the regional turmoil. Drawing on strategies gleaned from teaching about the Arab uprisings, this article asserts that the uprisings may be collectively read as comprising a text that contains signs of indeterminacy pointing to many possible meanings and sources of meanings. Focus is placed on those signs that embody the differing discourses through which the Middle East upheavals are, have been, or can be represented and assessed; and the fluid, multidimensional forms of political identity that have contributed to the upheavals, and are being further reshaped, in their wake. By reading these signs with intellectual openness and humility, interpreters can achieve greater insight into the profoundly contingent and unforeseeable dynamics at work across the region.  相似文献
