Additional Information In lieu of an abstract, here is a brief excerpt of the content: Models and Realities in Modern Human Origins: Claims for the presence of anatomically modern humans in Africa prior to ka and for the transition leading to modern Africans at an even earlier date have been made, partly based on results of these techniques. However, a careful examination of the pertinent record shows that these claims are not unequivocally supported by theavailable fossil and chronological evidence. As recently as , implications arising from these factors also led the eminent Africanist J. Desmond Clark to suggest that archaic humans in southern Africa were suddenly and relatively recently replaced by invading modern humans who had emerged in some other region of the Old World Clark In , a uranium-thoriumdate of ka was derived from Etheria shell associated with a partial human skeleton 1 Department ofAnthropology, Northern Illinois University, DeKalb, Illinois, , U. Therefore, because modern human remains were presumably associated with MSA deposits, particularlyat thesites of Border Cave and Omo KHS, initial arguments began to surface in the late s postulating that the earliest appearance of modern humans was in southern Africa. Thereare no unequivocal regionalor cladefeatures which demonstrate in a cladistic sense an African influence on early modern Eurasians Smith ; Wolpoff , Africa must be shown to have theearliest evidence of a transition in the direction ofthe modernhuman anatomical pattern and,ideally, theearliest evidence of theappearance of that pattern.

See Article History Alternative Titles: Piltdown man, whose fossils were sufficiently convincing to generate a scholarly controversy lasting more than 40 years, was one of the most successful hoaxes in the history of science. In a series of discoveries in —12, Charles Dawson, an English lawyer and amateur geologist, found what appeared to be the fossilized fragments of a cranium, a jawbone, and other specimens in a gravel formation at Barkham Manor on Piltdown Common near Lewes in Sussex.
Woodward claimed that the fossils represented a previously unknown species of extinct hominin Eoanthropus dawsoni that could be the missing evolutionary link between apes and early humans. His claims were eagerly and uncritically endorsed by some prominent English scientists, perhaps because the Piltdown fossils suggested that the British Isles had been an important site of early human evolution.
As long as the remains were accorded a high antiquity, Piltdown man seemed a feasible alternative to Homo erectus then known from scanty remains as Pithecanthropus as an ancestor of modern humans. In , however, the Piltdown gravels were found to be much less ancient than supposed, and, from , more finds of Pithecanthropus, the discoveries of the more primitive Australopithecus , and further examples of Neanderthals left Piltdown man completely isolated in the evolutionary sequence.
In —54, as an outcome of these discoveries, an intensive scientific reexamination of the Piltdown remains showed them to be the skillfully disguised fragments of a quite modern human cranium about years old , the jaw and teeth of an orangutan , and the tooth probably of a chimpanzee , all fraudulently introduced into the shallow gravels.
We are both 55 years of age and thanks to Evening Touch we are happy together and still in love and getting married in August , in Kitwe.

Incidentally, when rich deposits of lead were discovered near Kabwe in the early 19th century, Zambia, then w a British colony of Northern Rhodesia, mining of the precious metal was cardinal than the lives of the inhabitants or those who came and worked at the mine and later live within the surrounding areas. Although the mines or smelting of the lead is no more, the lead levels in Kabwe remain astronomically high and on average, five in every 10 children are exposed to lead pollution daily as they unknowingly get exposed to wind, dust as well as drink water contaminated with lead related material.
However, you could be excused for not knowing the other ecological part of it-the high toxicity and pollution of lead among the local people and the environment, especially in the former mining areas including Makululu Township where residents are victims of chest related problems for being constantly in contact with either wind or water, which carries with it various form of chemical or mineral substances.
Sample surveys undertaken by health experts show that there are and have for a long time now been increased cases of contamination of a multiplicity of lead in the people, causing respiratory problems, in the soil to toxins, in the water and radioactive fallout in the air. The local people like those in Makululu, the victims of the unwanted circumstance, are now used to living with the situation as the matter remains unabated for over five decades now.

R Catalogue of the exhibition, Johannesburg Art Gallery, The thirty-two artists who participated were tasked with creating, in a single day, an 8-page comic based on the work of Petrus Nooi, a sculptor who works in concrete and sells his pieces from his yard next to the road that connects Stellenbosch with the informal settlement of Khayelitsha. Critics, artists, writers, thinkers and academics were invited to bring and share a story, and then to relate it to an image, with the intention of exploring parallel experiences, memories and relationships to places.
