The fossil record suggests that modern human morphology evolved in Africa between 150,000 and 50,000 years ago, when the sole inhabitants of Eurasia were the Neanderthals and other equally nonmodern people. However, the earliest modern or near-modern Africans were behaviorally (archaeologically) indistinguishable from their nonmodern, Eurasian contemporaries, and it was only around 50,000-40,000 years ago that a major behavioral difference developed. Archaeological indications of this difference include the oldest indisputable ornaments (or art broadly understood); the oldest evidence for routine use of bone, ivory, and shell to produce formal (standardized) artifacts; greatly accelerated variation in stone artifact assemblages through time and space; and hunting-gathering innovations that promoted significantly larger populations. As a complex, the novel traits imply fully modern cognitive and communicative abilities, or more succinctly, the fully modern capacity for Culture. The competitive advantage of this capacity is obvious, and preliminary dates suggest that it appeared in Africa about 50,000 years ago and then successively in western Asia, eastern Europe, and western Europe, in keeping with an African origin. Arguably, the development of modern behavior depended on a neural change broadly like those that accompanied yet earlier archaeologically detectable behavioral advances. This explanation is problematic, however, because the putative change was in brain organization, not size, and fossil skulls provide little or no secure evidence for brain structure. Other potential objections to a neural advance in Africa 50,000-40,000 years ago or to the wider Out-of-Africa hypothesis, include archaeological evidence (1) that some Neanderthals were actually capable of fully modern behavior and (2) that some Africans were behaviorally modern more than 90,000 years ago.  相似文献

It has been amply demonstrated that individuals' reproductive capability is the key explanatory phenomenon for understanding onomastic disappearance during the early modern period. This article analyzes the evolution and consequences of surname extinction in a specific population: Catalonia in the sixteenth and seventeenth centuries. In this article two aspects are examined. First, the observed disappearance of surnames is estimated through historical data collected in the Llibres d'Esposalles (Marriage Books) from 1481 to 1600 at Barcelona Cathedral. Second, the estimated natural extinction of those surnames registered in 1481 is forecast by applying a statistical branching process.  相似文献

ABSTRACT

This research report aims to give detailed information on the pottery from the 1999 and 2013-16 excavation campaigns taking place at the Tell Sufan site in Nablus, Palestine. These were conducted by the Department of Antiquities at An-Najah National University (ANU) in Nablus. It is of note that this ancient pottery has never previously been the subject of research nor has any literature been published on it. Our methodology consists in: analysing the pottery by identifying it, typifying it, and giving it a function; providing chronological information on the site; comparison of the pottery with that from other sites in Palestine, using archaeological information from the site; and contextualising our findings with other historical and archaeological studies. Examination of the functional use of the pottery allows us to demonstrate human activity at the Tell Sufan site, giving information on the most prosperous phases of occupation in regard to economic aspects, through the late Bronze Age, Iron Age and Byzantine-Early Islamic periods.  相似文献

Pan, Z., Zhu, M., Zhu, Y. &; Jia, L., August 2017. A new antiarch placoderm from the Emsian (Early Devonian) of Wuding, Yunnan, China. Alcheringa 42, 10–21. ISSN 0311-5518.

Wufengshania magniforaminis, a new genus and species of the Euantiarcha (Placodermi: Antiarcha), is described from the late Emsian (Early Devonian) of Wuding, Yunnan, southwestern China. The referred specimens were three-dimensionally preserved in black shales, allowing a high-resolution computed tomography reconstruction of anatomical details. The new euantiarch is characterized by a large orbital fenestra, an arched exoskeletal band around the orbital fenestra and a developed obtected nuchal area of the skull roof. Maximum parsimony analysis, using a revised data-set of antiarchs with 44 taxa and 66 characters, resolves Wufengshania gen. nov. as a member of the Bothriolepididae, which is characterized by the presence of the infraorbital sensory canal diverging on the lateral plate, and the nuchal plate with orbital facets. New analysis supports a sister group relationship between Dianolepis and the Bothriolepididae. Luquanolepis, a coeval euantiarch from the neighboring site of the new form, is referred to the Asterolepidoidei and represents the basalmost and earliest member of the Asterolepidoidei.

Plusquellec, Y. &; Wright, A.J., October 2017. Revision of the Early Devonian tabulate coral Pleurodictyum bifidum from New South Wales. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

The tabulate coral Pleurodictyum bifidum Jones, 1944 Jones, O.A., 1944. Tabulata and Heliolitida from the Wellington district, N.S.W. Journal and Proceedings of the Royal Society of New South Wales 77, 3339. [Google Scholar], from the Early Devonian (Pragian or lower Emsian) Garra Formation of central New South Wales, Australia is revised on the basis of the holotype and three other specimens. It is selected as the type species of the new monotypic genus Bifidomeria (Family Roemeriidae), which differs from Roemeria in its strictly cerioid corallum, its bifid septal spines and aspects of its microstructure. Study of the detailed microstructure of two other tabulate corals from the Devonian of New South Wales has led to the following revised generic assignments: Michelinia progenitor Chapman, 1921 Chapman, F., 1921. New or little known fossils in the National Museum. Part XXV—some Silurian tabulate corals. Proceedings of the Royal Society of Victoria 33, 212225. [Google Scholar], previously assigned to Roemeripora, is assigned to Roemeria, and Holacanthopora clarkei Wright &; Flory, 1980 Wright, A.J. &; Flory, R.A., 1980. A new Early Devonian tabulate coral from the Mount Frome Limestone, near Mudgee, New South Wales. Proceedings of the Linnean Society of New South Wales 104, 211219. [Google Scholar] is assigned to Michelinia.

Earliest Triassic shales in the Coal Cliff Sandstone, Caley Formation, Widden Brook Conglomerate and Dooralong Shale (all basal Narrabeen Group) of the Sydney Basin contain a low diversity fossil flora that survived the greatest mass extinction of all time at the Permian-Triassic boundary. Only one species of seed fern is known from this flora and its affinities were unclear until discovery of its reproductive organs and complete large leaves. An ovuliferous reproductive organ, Peltaspermum townrovii sp. nov., can be attributed to the same plant as the leaves because of their identical stomatal apparatus, which is cyclocytic with papillae overhanging the stomatal pit. Polleniferous organs, Permotheca helbyi sp. nov., may have belonged to the same plant, but are only linked by evidence of association on the same bedding plane yielding no other gymnosperms. Pollen masses found within the polleniferous organ include grains identified as Falcisporites australis (de Jersey) Stevens (1981) when found dispersed. The leaves of this plant have long been enigmatic and attributed to ‘Thinnfeldia’ callipteroides or ‘Dicroidium’ callipteroides; however, these genera had very different cuticular structure. Reassessment of the frond architecture of this plant, based on a large, nearcomplete specimen together with information from cuticles and ovuliferous organs, allows reassignment to Lepidopteris callipteroides (Carpentier) comb. nov. The remarkable cuticle thickness, small stomatal size and low stomatal index of these leaves reflect a time of unusually high atmospheric concentrations of carbon dioxide. This plant was an invader of the Sydney Basin from northern Gondwana, spreading southward during the post-apocalyptic earliest Triassic greenhouse.  相似文献

CO2 injected into rock formations for deep geological storage must not leak to surface, since this would be economically and environmentally unfavourable, and could present a human health hazard. In Italy natural CO2 degassing to the surface via seeps is widespread, providing an insight into the various styles of subsurface ‘plumbing’ as well as surface expression of CO2 fluids. Here we investigate surface controls on the distribution of CO2 seep characteristics (type, flux and temperature) using a large geographical and historical data set. When the locations of documented seeps are compared to a synthetic statistically random data set, we find that the nature of the CO2 seeps is most strongly governed by the flow properties of the outcropping rocks, and local topography. Where low‐permeability rocks outcrop, numerous dry seeps occur and have a range of fluxes. Aqueous fluid flow will be limited in these low‐permeability rocks, and so relative permeability effects may enable preferential CO2 flow. CO2 vents typically occur along faults in rocks that are located above the water table or are low permeability. Diffuse seeps develop where CO2 (laterally supplied by these faults) emerges from the vadose zone and where CO2 degassing from groundwater follows a different flow path due to flow differences for water and CO2 gas. Bubbling water seeps (characterized by water bubbling with CO2) arise where CO2 supply enters the phreatic zone or an aquifer. CO2‐rich springs often emerge where valleys erode into CO2 aquifers, and these are typically high flux seeps. Seep type is known to influence human health risk at CO2 seeps in Italy, as well as the topography surrounding the seep which affects the rate of gas dispersion by wind. Identifying the physical controls on potential seep locations and seep type above engineered CO2 storage operations is therefore crucial to targeted site monitoring strategy and risk assessment. The surface geology and topography above a CO2 store must therefore be characterized in order to design the most effective monitoring strategy.  相似文献

Architecture in early modern Sardinia is characterized by a strong continuity with previous practices. In the second half of the 16th century, new models join the Gothic building tradition, linked in particular to trends in military engineering and Classicism of the Catholic Counter-Reformation. The Jesuit church in Sassari offers an interesting example of the intertwining of these architectural modes, which originated with a sudden change of leadership at the site. Giovan Maria Bernardoni, an Italian Jesuit architect, initially modeled the church after the Gesù in Rome, and it was partially built under his direction. After his departure from Sardinia, local master builders finished the construction, following the Gothic tradition and possibly some external influences. This article analyzes the church, particularly focusing on the challenges presented by its articulated vaulting system completed between 1587 and 1609.  相似文献

This article examines the “Jewish Indian” theory — which claimed that American Indians were the ten lost tribes of Israel — in 1650s England and New England. The theory found support in England while failing in New England. This difference in reception can be explained by considering its ecclesiological, political, and eschatological implications. Biblical commentators in both England and New England held to a form of “Judeo‐Centric” eschatology, which looked for a sudden, miraculous conversion of the Jews and their eventual superiority to Gentile believers. Such beliefs undermined crucial elements of New England ecclesiology when applied to Native Americans. Conversely, the New England Company used the theory in its publications as a fund‐raising tool in England. These publications impacted upon debates on Jewish readmission to England in the mid‐1650s, with New England missionary models suggested as a way of evangelising Jews. This article therefore argues for the importance of understanding eschatological beliefs in local contexts, while demonstrating the way in which such beliefs can be maintained and reoriented in the face of apparent disconfirmation.  相似文献
