ABSTRACT

The Namib Desert coast is rich in potential food resources, but its extreme aridity imposed severe limits on human settlement in the past. It appears that intensive use of the coast began in the Middle Holocene, although there is evidence of intermittent occupation from the Middle Pleistocene. Coastal sites were closely linked to the desert interior and movement between the two was mainly via the linear oases of ephemeral river systems. Contact was at first sporadic but regular trade with merchant vessels was established in the mid-eighteenth century AD. Coastal geomorphological processes determined the location and accessibility of marine resources used by hunter-gatherer and nomadic pastoral communities. At the same time, marine, fluvial, and aeolian processes have influenced the visibility and survival of archaeological evidence on the coast.  相似文献

Peel, J.S., February 2017. First records from Laurentia of some middle Cambrian (Series 3) sponge spicules. Alcheringa 41, 000–000. ISSN 0311-5518.

Spicules of the sponges Silicunculus Bengtson, Australispongia Dong & Knoll and Thoracospongia Mehl are described from the middle Cambrian (Cambrian Series 3) of North Greenland. The occurrences document the first records from the Cambrian of Laurentia of spicules initially reported from Australia. Obese spicules of Thoracospongia are now known to occur in strata of Cambrian Series 2 (Stage 4, Botoman) to Cambrian Series 3 (Stage 5 and Drumian) age in Australia, northern and southeastern Siberia and in the uppermost Henson Gletscher Formation (Cambrian Series 3, Stage 5) of western Peary Land. Morphologically similar obese spicules from the USA, Jordan, Iran and Sweden suggest an evolutionary trend towards armouring of the outer sponge surface during the middle and late Cambrian. New species described are Silicunculus saaqqutit sp. nov., Thoracospongia lacrimiformis sp. nov.

Writing The History of the Sevarambians in the 1670s, the Huguenot Denis Veiras borrowed many ideas from Garcilaso de la Vega, also known as El Inca, whose Royal Commentaries of the Incas was published in 1609. Both works describe the history of an empire and justify it on the ground that it brought peace and unity. While Garcilaso’s book purported to be a history, his selection of facts reflected his goal of improving the treatment of the Incas by the Spanish. Veiras’s story also claimed to be a history, but it was transparently a fiction, even to the point of lifting many elements from Garcilaso’s book. What both works equally emphasized was that empires could aim at, and could be justified by, the benefits they provided their subjects. Both tell stories of benevolent and paternalistic rulers who founded nearly ideal societies in the countries they conquered. These were models of empire for peace and unity rather than merely promoting toleration of differences or concord among differing parties. Veiras’s utopia thus offers an instructive case study of the effects of cross-cultural borrowings of literary and political ideas.  相似文献

Anthropologists working in the field of Australian native title are required to piece together the early laws and customs of claimant groups and assess the degree to which these have continued since the assumption of British sovereignty. The former task is often difficult in south‐eastern Australia because of a lack of good quality early records. I suggest here that there are general principles of Aboriginal land tenure that can be recovered from elsewhere in Aboriginal Australia, where the ethnography is of a better standard, and these can be used as a guide for working with the patchier materials characteristic of the south‐east. The principles mainly cohere around the organic relationship between patrilineal descent and complementary filiation, and are shown to be relevant to the modelling of contemporary south‐eastern tenure, where people speak of ‘bloodlines’ identified with ancestral lands.  相似文献
