Ciampate Del Diavolo
The Ciampate del Diavolo ( Neapolitan: "Devil's Footprints" or "Devil's Trails") is a locality near the extinct Roccamonfina volcano in northern Campania, Italy. It is named after fossilised footprints preserved in pyroclastic flow deposits that have been dated to around 350,000 years ago. They have been attributed to bipedal hominids, possibly ''Homo heidelbergensis'', which is known to have inhabited the region at the time. The footprints comprise three sets of tracks indicating that three hominids made their way down a steep slope on the flank of the volcano, away from the crater. The tracks were preserved under a layer of volcanic ash and were revealed by erosion, probably in the late 18th to early 19th century. Local people attributed the prints to the Devil as they regarded him as the only being capable of walking on lava without harm. They were identified as hominid footprints after archaeologists examined them in 2002 and are the second oldest set of hominid footprints ...

Lava
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Geography Of Campania
The geography of Campania illustrates the geographical characteristics of Campania, a region of Italy. General data From the gulfs of Gaeta, Naples, Policastro and Salerno to the most notable elevations of the Campania Apennines, Campania extends over a morphologically very varied territory. To the north it borders Lazio and Molise; to the east, Apulia and Basilicata, which it also borders to the south; to the west the Tyrrhenian Sea. Areas From a physical point of view, the Campania region can be divided into two areas: one mountainous and one flat: # The mountainous area includes the Campania Apennines, formed by a series of elevations, acrocores and plateaus (of Sannio, of Irpinia and of Cilento), between which open numerous and easy passes (the most important is the Sella di Ariano) and there flows the river Calore Irpino (left tributary of the Volturno) with its tributaries: Ufita ( in the center of the homonymous valley), Tammaro and Sabato. # The flat area is ...

Laetoli Footprints
Laetoli is a pre-historic site located in Enduleni ward of Ngorongoro District in Arusha Region, Tanzania. The site is dated to the Plio-Pleistocene and famous for its Hominina footprints, preserved in volcanic ash. The site of the Laetoli footprints (Site G) is located 45 km south of Olduvai gorge. The location and tracks were discovered by archaeologist Mary Leakey and her team in 1976, and were excavated by 1978. Based on analysis of the footfall impressions "The Laetoli Footprints" provided convincing evidence for the theory of bipedalism in Pliocene Hominina and received significant recognition by scientists and the public. Since 1998, paleontological expeditions have continued under the leadership of Amandus Kwekason of the National Museum of Tanzania and Terry Harrison of New York University, leading to the recovery of more than a dozen new Hominina finds, as well as a comprehensive reconstruction of the paleoecology. The site is a registered National Historic Sites of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleoanthropology
Paleoanthropology or paleo-anthropology is a branch of paleontology and anthropology which seeks to understand the early development of anatomically modern humans, a process known as hominization, through the reconstruction of evolutionary kinship lines within the family Hominidae, working from biological evidence (such as petrified skeletal remains, bone fragments, footprints) and cultural evidence (such as stone tools, artifacts, and settlement localities). The field draws from and combines primatology, paleontology, biological anthropology, and cultural anthropology. As technologies and methods advance, genetics plays an ever-increasing role, in particular to examine and compare DNA structure as a vital tool of research of the evolutionary kinship lines of related species and genera. Etymology The term paleoanthropology derives from Greek palaiós (παλαιός) "old, ancient", ánthrōpos (ἄνθρωπος) "man, human" and the suffix -logía (-λογία) "study of". Ho ...

University Of Padua
The University of Padua ( it, Università degli Studi di Padova, UNIPD) is an Italian university located in the city of Padua, region of Veneto, northern Italy. The University of Padua was founded in 1222 by a group of students and teachers from Bologna. Padua is the second-oldest university in Italy and the world's fifth-oldest surviving university. In 2010, the university had approximately 65,000 students. In 2021, it was ranked second "best university" among Italian institutions of higher education with more than 40,000 students according to Censis institute, and among the best 200 universities in the world according to ARWU. History The university is conventionally said to have been founded in 1222 when a large group of students and professors left the University of Bologna in search of more academic freedom ('Libertas scholastica'). The first subjects to be taught were law and theology. The curriculum expanded rapidly, and by 1399 the institution had divided in two: a ''Univ ...

Neanderthals
Neanderthals (, also ''Homo neanderthalensis'' and erroneously ''Homo sapiens neanderthalensis''), also written as Neandertals, are an Extinction, extinct species or subspecies of archaic humans who lived in Eurasia until about 40,000 years ago. While the "causes of Neanderthal disappearance about 40,000 years ago remain highly contested," demographic factors such as small population size, inbreeding and genetic drift, are considered probable factors. Other scholars have proposed competitive replacement, assimilation into the modern human genome (bred into extinction), great climate change, climatic change, disease, or a combination of these factors. It is unclear when the line of Neanderthals split from that of Early modern human, modern humans; studies have produced various intervals ranging from 315,000 to more than 800,000 years ago. The date of divergence of Neanderthals from their ancestor ''Homo heidelbergensis, H. heidelbergensis'' is also unclear. The oldest potential ...

Argon–argon Dating
Argon–argon (or 40Ar/39Ar) dating is a radiometric dating method invented to supersede potassiumargon (K/Ar) dating in accuracy. The older method required splitting samples into two for separate potassium and argon measurements, while the newer method requires only one rock fragment or mineral grain and uses a single measurement of argon isotopes. 40Ar/39Ar dating relies on neutron irradiation from a nuclear reactor to convert a stable form of potassium (39K) into the radioactive 39Ar. As long as a standard of known age is co-irradiated with unknown samples, it is possible to use a single measurement of argon isotopes to calculate the 40K/40Ar* ratio, and thus to calculate the age of the unknown sample. 40Ar* refers to the radiogenic 40Ar, i.e. the 40Ar produced from radioactive decay of 40K. 40Ar* does not include atmospheric argon adsorbed to the surface or inherited through diffusion and its calculated value is derived from measuring the 36Ar (which is assumed to be of atmosphe ...

Happisburgh Footprints
The Happisburgh footprints were a set of fossilized hominid footprints that date to the early Pleistocene, over 800,000 years ago. They were discovered in May 2013 in a newly uncovered sediment layer of the Cromer Forest Bed on a beach at Happisburgh in Norfolk, England, and carefully photographed in 3D before being destroyed by the tide shortly afterwards. Results of research on the footprints were announced on 7 February 2014 and identified them as the oldest known hominid footprints outside Africa.Ashton N, Lewis SG, De Groote I, Duffy SM, Bates M, et al. (201"Hominin Footprints from Early Pleistocene Deposits at Happisburgh, UK" ''PLoS ONE'' 9(2): e88329. Before the Happisburgh discovery, the oldest known footprints in Britain were at Uskmouth in South Wales, from the Mesolithic and carbon-dated to 4,600 BCE. The oldest known hominin footprints in Europe were the Ciampate del Diavolo tracks found at the Roccamonfina volcano in Italy, dated to around 350,000 years ago. Wi ...

Devil
A devil is the personification of evil as it is conceived in various cultures and religious traditions. It is seen as the objectification of a hostile and destructive force. Jeffrey Burton Russell states that the different conceptions of the devil can be summed up as 1) a principle of evil independent from God, 2) an aspect of God, 3) a created being turning evil (a ''fallen angel''), and 4) a symbol of human evil. Each tradition, culture, and religion with a devil in its mythos offers a different lens on manifestations of evil.Jeffrey Burton Russell, ''The Devil: Perceptions of Evil from Antiquity to Primitive Christianity'', Cornell University Press 1987 , pp. 41–75 The history of these perspectives intertwines with theology, mythology, psychiatry, art, and literature developing independently within each of the traditions. It occurs historically in many contexts and cultures, and is given many different names— Satan, Lucifer, Beelzebub, Mephistopheles, Iblis—and at ...
