The Prehistory Of Human Existence

Homo erectus was first found in Africa and the fossilized remains dated 1.8 and 1.0 million years old. The Homo erectus traits are very similar toward the modern human traits. Homo erectus brain size was smaller than the Homo sapiens. Homo erectus had a brain size of approximately 650 cc and Homo sapiens had a brain size of approximately 1251

In the quest to explain human origins it is necessary to find a species that bridges modern man (Homo sapiens) with the apes. To fill this gap evolutionists have set forth Homo erectus, who lived approximately 400,000 to 1.6 million years ago (Johanson and Shreeve1989). Although the distinctions are somewhat vague, below the neck, Homo sapiens and Homo erectus are practically Identical and Homo erectus was responsible for pioneering the use of standard tools (such as the hand axe), big-game hunting, and the use of fire (Johanson and Shreeve1989).

This chapter does argue about the human history before civilization. It mentions how history courses and books leave out information about the human journey. Historians leave out Paleolithic and Neolithic eras.

In the Article “Redrawing Humanity’s Family Tree” by John Noble Wilford, describes how two different skulls challenge the theories of human origins and migrations. The Central African skull, that dates back to nearly 7 million years ago, was assigned to a whole new genus and species because of its apelike and evolved hominid species. The 1.75-million-year-old Georgian skull shows evidence that the first hominids may have been intercontinental travelers who set motion the migrations that occupied the whole planet. Finally a third skull was found that is the same age and shares a resemblance but, the size of the skull suggests that the brain was smaller than expected for H. erectus.

“Despite intense research efforts, no consensus has been reached about the genetic relationship between early modern humans and archaic human forms such as the Neanderthals” (Serre, 16 March 2004). It is a

If Neanderthals did in fact comport themselves in ways once thought to distinguish anatomically modern humans and enable the latter’s rise to world domination, that similarity makes the Neanderthals’ decline and eventual extinction all the more mystifying. One theory is that H. sapiens had a broader variety of tools that may have enhanced their ability to forage. When they brought their superior technology with them out of Africa and into Eurasia, they were thus better able to exploit the environment more effectively than the resident Neanderthals could. Still, the arrival of H. sapiens did not equal an instant demise for Neanderthals. The latest attempt to track their decline, carried out by Thomas Higham of Oxford and his colleagues, applied

timeline of modern humans, Homo sapiens, and how long they have been in existence. According to mainstream science, popular belief holds that the history of our species is confirmed to be confined to the past 12,000 years. This figure is a culmination based on what we know about evolution and what we have been able to gather through fossil analyzation and dating of artifacts as well as human remains. Although the subject of human antiquity, also referred to as human origins, does not prompt a great deal of debate there may actually be the need for some. A reexamination of the notion that humans have only existed a mere 12,000 years should be considered as there may be evidence to support a much greater antiquity of modern human life. Alternative researchers have offered up evidence of “forbidden archeology” that contradicts the mainstream beliefs of human origins, however these discoveries seem to have been swept under the scientific rug.

“How old is the oldest human fossil?,” If you had said about 700,000 years, you would probably have been right until just recently that is, “The September 1998 issue of Discover magazine”, reports that Ernesto Abbate, a geology professor from Florence, Italy, has just discovered the fossilized skull and teeth of a humanlike creature who might have lived, as far back as, one million years ago. Calling this creature Buia Man after the city in northeastern Africa where the remains were found. Prof. Abbate thinks he has discovered the earliest fossil that displays physical features associated with Homo sapiens, the species to which modern humans belong. Moreover, Buia Man says, Prof. Abbate also shows physical

According to Diamond, Human ancestors moved to Eurasia around 1 to 2 million years ago and after human fossils began to resemble modern Homo sapiens and archaeologists called that period the Great Leap Forward. According to “Human Evolution and the Great Leap Forward - By Advocate De Waal Lubbe,” Scientists have estimated that humans branched off from their common ancestor, with chimpanzees, about 5-7 million years ago. Several species and subspecies of Homo evolved and are now extinct. These include Homo erectus, which inhabited Asia, and Homo Sapiens Neanderthalensis, which inhabited Europe. Archaic Homo sapiens evolved between 400,000 and 250,000 years ago.

Many of the features that distinguish Homo erectus from other hominin species—both earlier and later species—are seen in the skull. The average brain size of Homo erectus is estimated to have been roughly 900 cubic centimeters (cc.), which is larger than Homo habilis, but smaller than that of Homo heidelbergensis and other later forms. The size of the Homo erectus brain is negligibly larger than in Homo habilis when it is considered as in relation to body size—i.e., brain size increased substantially in Homo erectus, but, because body size also increased, the relative size of the Homo erectus brain is not considerably larger than that of Homo habilis. The absolute in brain size, however, caused changes in the brain case; for instance, the

By 0.6 Mya, H. heidelbergensis appeared. Likely an ancestor of our own species, their fossils have been found with the remnants of large, butchered animals and hand axes -- suggesting a good degree of tool usage. It is unknown whether or not they actively hunted the large animals that they hunted, but the prolifacy of these butchering sites would suggest that Heidelbergensis was able to have consistent access to these large carcasses. Examination of fossilized hyoid bones in Heidelbergensis indicates that they were also capable of making the nuanced sounds required for speech (Martínez I, et. al.). Their easy access to food and fire probably came in handy during the Kansan glacial period, which lasted from 0.46 to 0.30 Mya. It was during this icy period that the lineages of Homo sapiens and Homo neanderthalensis finally split from that of H. heidelbergensis and begin to truly hunt for their food.

The earliest H. erectus is found in Arica, and one of most spectacular fossil comes from Nariokotome. According to these fossils, the anthologists found that H. erectus share some features with modern human beings. Firstly, the ratio of arm length and leg length of H. erectus is much more like human being. This feature means that H. erectus has adapted the life on the ground. Secondly, H. erectus has a larger brain size. Thirdly, a sets of footprints that are found in Ileret show us the footprints that can be dated to 1.5 may and we notice that H. erectus can walk like modern humans because they have same feet with us. In the process of cleaning the face bone of the Bodo skull, Tim White notice that there are many marks that left on the cheek, and he think these marks were made by stone tool and maybe it is a form of ritual, which may be a evidence that human try to

According to physical evidence, and theories, scholars have concluded upon a whole hypothesis. Based on their knowledge and belief, modern humans diverged from Homo sapiens between 200,000 and 150,000 years ago specifically in Africa, that between 125,000 and 60,000 years ago members of Homo sapiens left Africa, and that these

The earliest inhabitants of Britain for whom there is compelling evidence are bands of hunters living in Southern and Western England during the Hoxnian interglacial (about 380,000 to 400,000 BC). (Some very recent excavations of stone tools on the East Anglian coastline suggest human presence as early as 700,000 years ago). However, as temperatures again dropped, Britain was abandoned. Although there are signs of human habitation during later interglacials, it was not until roughly 14,000 years ago that occupation became permanent. Some of the first things that Mesolithic Britons did, were to wipe out the lion, the elephant, and the hippopotamus, and to domesticate the dog. By about 6000 BC the melting of the ice sheet had created the English

The next species to appear were the Homo erectus which might have descended from Homo habilis. They were the first human whose fossils were found outside of Africa. They also had larger brain than the species before them. Homo sapiens sapiens came after the Homo Neanderthalensis; they are the only human species around. This could have been due to the result of increase brain sizes that allows more cognitive abilities that help them adapt to different environment changes and hence survive. Global evidence have been found of art, music, and culture and advanced tool making. In Mithen’s 3 phase of mind proposes that the shape of the Neanderthals’ frontal lobe was similar to the one of the modern Homo sapiens and this indicated that they were able to cope with complex cognitive functioning. Evidence for this could be explained using the phonological approach by Frank Gall (1758-1828).
