This development is paralleled by a similar change of direction in evolutionary thinking, and in both cases it seems likely that the impetus is being largely propelled by the discovery of the erectus specimen KNM - WT 15000 in Africa in 1984.This attitudinal shift has connotations for the whole topic of alleged evolution of human beings.TW15000 is the skeleton of an immature boy, about 9-12 years of age, already more than 5 feet in height at the time of death Its height is a significant increase in size over earlier hominids which were about the size of modern chimpanzees.At maturity it might have attained a height of about 6 feet and approximately 150 lbs. Cause of death is unknown but evidence of abscessed teeth may indicate septicemia as the cause.Endocast of the Nariokotome/Turkana boy's brain cavity indicate that Broca's area of the brain (a part of the brain that serves essential functions in speech), showed visible signs development.However, it is unlikely he was able to speak as modern humans do due to anatomical characteristics indicating that differences in breathing would have made complex sound production problematic. Koobi Fora is one of the richest fossil sites on earth. habilis, Paranthropus boisei, Paranthropus aethiopicus and Kenyanthropus platyops. Confounding the debate is the issue of whether or not these are even two different species of the genus Homo. Originally described by Louis Leakey, John Napier, and Philip Tobias from finds at Olduvai Gorge, Tanzania, in 1964, H.Having survived for more than 1.5 million years, it was particularly successful. erectus had a low and rounded braincase, elongated from front to back, a pronounced brow ridge, and a cranial capacity of 800 to 1,250 cc in adults. Neanderthals were extent between about 200,000 and 36,000 years ago and may have persisted as late as 28-24,000 years ago.
In evolutionary circles it is becoming increasingly common to argue that although H.
Turkana Boy, also known as Nariokotome Boy, is a nearly complete skeleton discovered in West Turkana, Kenya, August 22, 1984 by Kamoya Kimeu.
It is one of the most significant finds in paleoanthropology.
With the appearance of the Javan and Peking fossils it seemed that evolutionary theory had been vindicated to a sizeable degree, and Pithecanthropus (ape-man) became a common term in public as well as in palaeoanthropological circles. With the rise of the post-World War II creationist movement, largely sparked by the epic work of Whitcomb and Morris in 1961, one of the most urgent tasks involved was how to respond to this apparent chain of evolutionary progression.
After the Piltdown fraud was exposed, the australopithecines came into favour as a transitional form linking an ape-like common-ancestor to human beings, and this link was further strengthened by later finds of both erectus and australopithecine fossils, mainly in East and South. By the early 1970s, more finds including australopithecus-like material classified as Homo habilis, made it appear that there was now a fairly substantial chain of progressive evolution from a bipedal chimp-like ancestor right through to modern man - A. In the intervening years since then, creation-oriented scientists have made a number of attacks on the validity of most of these forms, some of them being of high technical quality, others a little less well-informed.
