Homo Neanderthalensis- the Neanderthals

Neanderthals were hunter-gatherers who moved across Europe with the advance and retreat of the Ice Age glaciers. Their total population probably never exceeded 100,000. From 180,000 to 130,000years ago large glaciers covered much of Europe and Neanderthal remains are scarce. After 130,000years ago, tool technology developed rapidly to become the classic Neanderthal technology called the

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

To get a sense of what it is to be human, at least in the evolutionary world, we need only to compare our modern selves to our ancestors such as the Neanderthals. The Neanderthals were our closest hominin relative and died out thousands of years ago. Like us, they walked on two legs, hunted , made fire and tools, and lived in shelters (caves). They were more advanced than many of us imagine they were thanks to the way they are portrayed in the media. They had brains similar in size to ours, they stood fully upright (not hunched over), and had a surprisingly complex culture. When asked what it means to be human, you can compare many different aspects of our lives, such as biology, culture, and even religious beliefs. We obviously have

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

The Neanderthals lived in areas ranging from Western Europe through central Asia from about 200,000 to between 36,000 and 24,000 years ago. The Neanderthals lived in groups of 30 to 50 individuals, they invented many of the tool types that were to be perfected by fully sapient peoples, they had weapons adequate to deal with both the cave lion and cave bear, they used body paint, buried their dead. Neanderthal Man survived through the Ice Age. They are thought to have had fire. Neanderthals lived side by side with modern humans for over 10,000 years.

The fossils which passed the amino acid tests were called “transitional” elements between the two species.  They represented a part of Europe where the Neanderthals and early humans would have more than likely encountered each other.  The same DNA sequence was found in Neanderthals and early humans, but also in ancient cave bears from Croatia and Austria.  This made the researchers skeptical of their findings and decided to test for mtDNA stands.  When the fossils were further analyzed, the researchers found that the mtDNA embedded in the Neanderthal fossils was of a different strain than that in the early humans, which was of course, different from that of the ancient cave bears.

There were 24 Neanderthal remains and 40 early modern human remains that were studied. The bimolecular preservation of DNA of five early humans and four Neanderthals was helpful enough for the preservation.

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

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 question of the coexistence and the potential interaction between the last Neanderthal and the earliest intrusive populations of anatomically modern humans in Europe has been a topic of debate. The extinction of the Neanderthals occurred during the latter part of the last glaciation which was characterized by a rapidly changing climate, cold conditions and corresponding vegetation and faunal turnover. However, it coincided with the expansion of modern humans out of Africa during the Late Pleistocene. Thus, it has been an ongoing debate on whether the extinction of the Neanderthals was due to competition with anatomically modern humans or due to climate change. It is argued that the inability for the Neanderthals to adapt to climate

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

The first Neanderthal fossils found in Europe, a fragmented child’s cranium in Belgium in 1830, and an adult cranium in Gibraltar, were not immediately recognized as a divergent kind of human. Only in 1856 after a partial skeleton was found in a cave in the Neander Valley in Germany it became clear that these fossils belonged to an extinct human and our closest evolutionary relative (Hublin and Pääbo, 2006). Since then, questions about their relationship with modern humans have been fiercely debated between anthropologists. But what attracts most interest from scientists and popular media is the possibility of hybridization between Neanderthals and modern humans if, in other words, they were a genetically different specie or a

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).

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
