The Species Of Homo Neanderthalensis Essay

The first Neanderthal remains, discovered in Germany in 1856, were presented to the world of science at a meeting of the Lower Rhine Medical and Natural History Society held in Bonn in February 1857 and named a species, Homo neanderthalensis, by William King in 1864. Some Neanderthal fossils and other remains are in excellent condition, giving a good idea of Neanderthal culture. In 1887, two complete skeletons were found in a cave near Spy in Belgium, and more from sites in France in 1887, 1908 and 1911. These and other finds showed that the Neanderthals had populated Europe widely from about 130,000 to 28,000 years ago after which they became extinct. Most of these fossils were found in caves. Usually they are associated with cold

In a skeleton found in Asia, the discovery of a hyoid bone in the the throat raised the question of whether or not Neanderthals had language capabilities. There has been much debate over this and many different theories, but the most widely accepted is that they were capable of producing human speech sounds, but whether or not they used this speech to communicate in any kind of language is still largely up for debate. In height, Neanderthals were roughly about the same size as modern humans, but did not live as long as modern humans. A Neanderthal who lived into his or her 40's was considered to be long lived, which is comparatively short to our much longer lives of roughly double that. Genetically, Neaderthals and humans differ in their DNA structure both in the mitochondrial DNA and in the nuclear DNA. The significance of the DNA evidence is that it is crucial in determining whether remains that are found are truly Neanderthal or an older hominin relative.

According to “Decoding Neanderthals’ they were consider primitive; without language and art or a high level of thinking. These species hunted by brute force with a simple stone tool. Also, that their intellect cannot be associated or compared with modern humans because their behavior was too way primitive. They began to disappear 40,000 years ago as modern humans came on the scene, stated by “Decoding Neanderthals” documentary movie. However, according to the genetic evidence shows a mysterious presence related with the modern humans genes. Neanderthal’s psychical features demonstrate some facts that these Homo species possessed intelligence. For example, big noses, bulky physiques-adaptation to cold, shorter than Homo sapiens, but bones were thicker, oblique forehead and heavy eyebrows. Also, often Neanderthal’s craniums are larger than modern humans. They had larger ankle joint, elbow joint and shorter forearm, broader ribcage and lower cranium. They were the most advanced group of primates, except modern humans. Neanderthals weren’t fewer intelligent than modern people; they had clothes and had some kind of language. Neanderthal living space showed complex use of the instrument, abstract thoughts and speech, burial of their dead and manufactured primitive art objects. Some stereotypes against these species are that they had limited stone tools and no art or personal ornaments; therefore they seemed less advanced than modern humans. Also, stereotyping their intelligence

Neanderthals were a species of archaic humans who migrated out of Africa and into Europe and Asia. However, around 40,000 years ago the large populations of Neanderthals died off and became extinct. The mysterious circumstances that surrounded their extinction drove various research teams to undertake the task of excavating numerous Neanderthal sites to collect fossilized bones, and artifacts in order to learn more about this group of ancestral humans. Over the past years, major technological advances have allowed researches to analyze the fossilized remains of the Neanderthals which led to major discoveries. For example, researchers at the Max Planck Institute for Evolutionary Anthropology found that the ear ossicles of Neanderthals and modern humans had similar functions but differed in terms of structure. In the study, the researchers used high-resolution computer tomography (CT) to scan numerous Neanderthal skulls from different sites in order to determine if there are ossicles present in the middle ear cavity (tympanic membrane). The scans revealed ossicles in fourteen different skulls which came as a surprise to the researchers since the bones of the ossicles are fragile and break down easily in the soil. The researchers then used microcomputed tomography scans and 3D geometric morphometrics in order to virtually reconstruct the bones of the ossicles which are composed of the malleus, incus and stapes. The 3D reconstructions of the ossicles allowed the scientists to

The most recent ancestor to the modern human, Homo neanderthalensis existed between 300,000 and 35,000 years ago. Originating in Africa, ancestors of the early Neanderthals migrated northwards almost 800,000 years ago. These migrants colonized much of the Old World with the majority based in Europe and small groups scattered throughout the Middle East and Asia. Historically, the Neanderthals were among the most resiliant creatures to exist on Earth. As a population, they thrived during the European ice age 40,000 years ago. This ice age enveloped the majority of Northern and Central Europe and due to their physique were the Neanderthals were able to surive. Physcially, the Neanderthals were larger and more muscular than today’s human

It's widely agreed by scientists that Neanderthals and Homo sapiens (modern man) are different species. However, it's thought that 1.5 - 2.1% of DNA from anyone born outside of Africa is Neanderthal which means that they co-existed and interbred with our Homo sapien ancestors approximately 35,000 years ago. Researchers say, the only human ancestors who didn't interbreed with Neanderthals were sub-Saharan Africans. Neanderthals typically lived in Europe and Asia up until approximately 33,000 BC when they are said to have become extinct. They lived during the Ice Age and can be considered as early cave men who are likely to have been covered in hair and had an ape like appearance very similar to the conventional perception of Bigfoot. Their eyes and brains were larger than those of Homo sapiens but they were sophisticated enough to carry tools, make fire and bury their dead. One scientific explanation as to why the Neanderthals died out is climate change, More likely, they were unable to compete with the better adapted early humans who either killed them, took over their land or interbred with them and they were absorbed into our

Neanderthals and modern humans coexisted for well over 100,000 years.  Then suddenly Homo neandertalensis began to die out and surrender the earth to Homo sapiens.  Paleontologists and anthropologists have entertained several possibilities to the causes of this event: interbreeding among Neanderthals and humans, competition for natural resources, and Darwin’s theory of “survival of the fittest.”  What the real cause has been has plagued scientists for years. Now, due to an international research team from Germany, those possibilities have been even further deduced, making it easier to pinpoint the exact reason Homo neandertalensis became extinct.

While it is important to understand the significance of each hypothesis, the questions surrounding the Neanderthal extinction takes on assorted factors that are not mutually exclusive. Numerous studies have been conducted focusing exclusively on climate, competition or disease as a function of Neanderthal extinction. However, conflicting conclusion suggest that there are several factors involved that overlap and/ or arising from one another. This paper will attempt to better understand how climate, competition, and disease might operate together to account for Neanderthal extinction. First by summarizing each argument of the three arguments and identifying the potential implications for father research. Secondly, aim to develop a framework that will include the most relevant hypothesis.

The Neanderthals

The next major step in human development is the Neanderthal. In Comparison to the other primates discussed this far, Neanderthals existed very recently and existed alongside Homo Sapiens during their time until they became extinct 40,000 years ago. Humans and Neanderthals share DNA that is 99.7% identical as compared to the next closest genetic relative the Chimpanzee(98.8%). Physically Neanderthals had short legs and long bodies (compared to humans). Neanderthals had a cranial capacity of 1,427 cubic centimeters on average,this is very close to the H. sapiens cranial capacity..

Throughout the documentary “Decoding Neanderthals” there was a push of research to push the human view of Neanderthals. Over the year’s research showed that we coexisted with Neanderthals and out beat their species. Many believed that Neanderthals where like the stereotypical unintelligent and wild caveman. With new technology, enhanced research, and the exposing documentary “Decoding Neanderthals” pushed the boundaries of these past ideologies. Through this we have learned how intelligent, symbolic, and closely related this species is to homo-sapiens species. This research proved that the Neanderthal may have not became extent due to in ability to create weapons but, due to inter breading with humans

During the 1980s, three specialists, Allan Wilson, Rebecca Cann and Mark Stoneking, worked together on another theory that supports Charles Darwin's speculation, the “Mitochondrial Eve” hypothesis. In these tests, the scientists solemnly focused on mitochondrial DNA, human genes that lay within the cell and are passed from mother to child. These genes allow mutation, as they mutate quickly for adaptation, thus allowing those studying to find and track changes during short time periods. By focusing on these genes and comparing their differences, the three scientists were able to create a hypothesis about the time and place when modern humans began to evolve. According to their findings, they believe that modern humans are decentants from a single population, while earlier humans e.g. Neandertals and Homo erectus, had become extinct. Furthermore, the team compared the DNA of numerous people of differerent ethnic backgrounds and concluded that all humans did indeed evolve from 'one mother' in Africa about 150,000 years ago.

Several different hypotheses have been formulated to explain the extinction of Neanderthals, from climate changes to intoxication from cave-associated contaminants like smoke, from cannibalism to diseases (Herrera et al., 2009). It is only certain that Neanderthals disappeared from fossil record after the arrival of modern humans, around 40,000 years in Asia, and 10,000-15,000 years in Europe (Shreeve, 1995). Fossil evidence shows the presence of modern humans in Middle East from 130,000 to 75,000 years ago, in the same areas where Neanderthals retreated between 65,000 and 47,000 years ago (Mellars, 2004).

There is evidence to suggest that Homo neanderthalensis and Homo sapiens had coexisted for approximately 35-40,000 years, (Fagan 2010) from around 60,000 years ago to 25,000 years ago when they finally went extinct (Gibbon 2001). Anthropologists are still uncertain what the cause of their extinction was. This paper will analyze three main theories of Neanderthal extinction. The first theory is the competition theory, which claims that the Homo sapiens and Neanderthals had to compete for resources, ultimately leading to their demise. The second theory I will discuss is the climate change theory, which claims that Homo sapiens lived while Neanderthals died because they were better adapted to the climate. The last theory I will discuss is

There has been a great deal of heated debate for the last few decades about where modern Homo sapiens originated. From the battle grounds, two main theories emerged. One theory, labeled “Out-of-Africa” or “population replacement” explains that all modern Homo sapiens evolved from a common Homo erectus ancestor in Africa 100,000 years ago. The species began to spread and replace all other archaic human-like populations around 35,000 to 89,000 years ago. The rivaling opinion, entitled the “regional continuity” theory or “multiregional evolution” model refutes this theory and states modern humans evolved from various species of Homo erectus who interbred with others that lived in
