Neanderthal Evolution

Research speculates that the modern humans and Neanderthals coexisted in Europe for around 5,000 years. To put that into perspective, 5,000 years is around 250 generations in “human-time.” Sharing about 99.5% DNA with the Neanderthals, the largest bone in the foot may be one of the biggest differences that set the modern humans apart to out-live the Neanderthals. Both Neanderthals and modern humans have arched feet, but the height of heal differs. Dr David Raichlen found that because the heal of the Neanderthal was taller, it proved less spring during running and also stabilized the ankle. This made the Neanderthals known for walking, and to which why the lower heal increased the ability for modern humans to out run its closest cousin.

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

Traditionally, Neanderthals have been viewed as large, hulking ape like beings that survived by aggression and power through the harshest conditions possible on earth. They have been painted as unsophisticated and unable to compete with humans on an intellectual level. These academics theorized that superior human intellect and reasoning gave humans the advantage in hunting game and securing the most valuable natural resource, eventually driving the Homo neanderthalensis to extinction 30,000 years ago. Popular culture describes Neanderthals as first viewed by science as large, hulking ape like beings. However, new evidence suggests that one of the first reconstructed Neanderthal skeletons did not consider that the individual suffered from acute arthritis. Despite unique, this Neanderthal ‘s hunching posture was associated with the entire species, giving one the impression of a “brutish caveman”. This new understanding has reformed research on the Neanderthal and a new understanding of humanity’s earliest ancestor

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

The upbringing of Neanderthal children is believed by some scientists to have been harsh. High activity levels and frequent periods of scarcity form part of the basis for this interpretation. However, such trials in childhood may not be distinctive from the normal experiences of early modern human children, or those of hunter-gatherers in particularly cold environments. There is a crucial distinction to be made between a harsh childhood and a childhood lived in a harsh environment. Anatomical analyses of Neanderthal long bones have revealed that survival depended on adapting to high levels of activity and a rugged terrain. However, there is little to distinguish Neanderthal physical stamina from that of early modern humans. Both populations

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.

“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

comparable to the sun and the moon? What about King Solomon. Sol (soul)(sun) , Mon (moon) (man), so could this equate to the king of the soul of man? New information is emerging about our neanderthal predecessors all the time. For example, their are discussions now about

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

The evolutionary of human living has taken place over millions of years of geological time. It has evolved millions of generations, and billions of individuals. The human evolution is not understandable completely yet. Evolutionary change within a population can take place at different time and different rates, which yield different consequences. This process still taking place in the natural selection and human evolution. One species may be merged to the new species or developed to the next stage of the same species. Homo Habilis, Homo Erectus, Homo Heidelbergensis, and Neanderthals were the close ancestors of modern human, which developed from Australopithecus afarensis.

As mentioned earlier, the Neandertals possessed large, stocky physiques that were built to withstand the frosty weather. This is an example of a biological adaptation in response to their terrain. Without their large builds, the Neandertals would not stand a chance in the wintry weather. Along with their biological adaptation, Neandertals adopted behavioral changes as well. They even began clothing themselves. It is said, Neandertals used animal skins and hides to protect themselves from the cold (Stanton, et al., 2013, p. 405). While they clothed themselves, it was not fully effective protection against hypothermia. Hypothermia is a probable explanation to the extinction of the Neandertals; however, the Neandertals avoided the climate by seasonally migrating over long distances or by moving as overall conditions get colder (or warmer) during all parts of the year (Stanton, et al., 2013, p. 406). With their migration system, they were out in the open and inadequate portable insulation had additional ramifications for Neandertal survival (Gilligan, 2007, p. 507). The Neandertals lived nomadic lifestyles and that contributed to compromises in their hunting and gather activities as well as their fertility rates (Gilligan, 2007, p. 507). There was an evident rise in their adult mortality rates alongside with their even higher infant mortality, in view of the fact that they render infants more prone to hypothermia as

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 Akeer Wars brought an abrupt end to the advancement of the most advanced of the human-like species that were developing from the Homo Heidelbergensis evolutionary path. There are two contenders noted as possible aggressors in this War, the Homo Sapiens, or the Homo Neanderthalensis. Although most modern theories point to Homo Sapiens at the attacking species, it is still quite possible, and even probably, that the horrendous attacks were carried out at the hands of the Homo Neanderthalensis. In fact, Homo Sapiens could very well be entirely innocent in the chaos surrounding the war.

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
