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 single specie capable of producing offspring.
The first morphological features that later would become typical of Neanderthals, the projecting middle part of the face and a depression at the back of the skull, have been observed in fossils found in Europe as old as 400,000 years (Stringer & Hublin, 1999). These fossils belonged to Homo heidelbergensis, which in one of the various evolutionary scenarios that ties Neanderthals and modern humans is considered the ancestor of both Homo neanderthalensis and Homo sapiens (Hubmlin, 2009).
Neanderthals lived in Europe and Western Asia between 200,000 and 30,000 years ago. Fossil record shows that around 150,000 years ago (Bar-Yosef, 1998; Grün & Stringer, 2000) their range extended from Europe to Middle East and Asia spreading to Uzbekistan and Russia (Herrera et al., 2009). They were probably the only hominin group living in Europe and Western Asia for a long period of time until the arrival of modern humans. Their extinction is dated at around 30,000 ye...

The skull was given the scientific name: Sahelanthropus tchadensis and was nicknamed Toumai, which is a local name for a child born perilously close to the beginning of the dry season meaning “Hope of Life” (Walton). The skull has a mix of ape and hominid, early humans who are distinctly different from apes by their upright posture, features. The brain case is similar to those of apes, being about the size as a chimp, but the thick tooth enamel and the presence of small canines in the jaw bone are features that are similar to hominids. The most surprising part of the skull is the presence of the large brow ridges found on Toumai (Groves). This is unexpected because the next oldest hominid fossils have a small or non-existent brow ridges but our family, Homo, also has large prominent brow ridges (Gee).
These individuals are portrayed by modern society as brooding, selfish, beasts of nature. Evidence can be pulled from all over Europe to provide a perfect explanation about how Neanderthals were anything but. Neanderthals had the ability to take care and look after those who could not do so for their self. One of the best-known cases of compassion among the Neanderthals was the “Old Man of La Chapelle.” This name was given to a male found in a limestone bedrock found in France in 1908. He was dated to have lived 56,000 years ago and was the first nearly complete Neanderthal specimen ever found. Scientist estimate that he was relatively old by Neanderthal standards and where his teeth used to be have now been grown in with bone. This indicates that the man lost his teeth sometimes long before he died, allowing the gums to heal and bone to takes it place. He was lacking teeth and would have had trouble chewing his food, this combined with his age would have made survival rather difficult. The old man’s skeleton was also riddled with other sorts of ailments, broken bones, which made life difficult to handle unless he had helped. The other members of the community would have worked together to take care of him until his death. Other Neanderthals remains have signs of server damage that could have been potentially life-threatening, but evidence shows that some of the injuries were completely healed. Indicating that those Neanderthals that had suffered grievous injuries were nursed back to health by other members of the

In recent years, the Homo Neanderthalensis were viewed as “subhuman brutes”, but are now seen as a different species from our own (Balter 2001). The Neanderthals were a branch of the Homo genus that evolved in Eurasia at least 200,000 years ago (Fagan 2010). The first Neand...
The Neanderthals are an extinct species of human that lived in ice age Europe between 120,000-35,000 years ago. This species is known for their receding forehead and prominent brow ridges. We know this species as the uncivilized or unintelligent person or group. Neanderthals are often portrayed as “unintelligent cavemen in animal-skin clothing.” Scientists’ first thought the Neanderthals’ were subhuman, but that thought is beginning to change. The original name given to the Neanderthals when they were first discovered was ‘Homo Neanderthalensis’ and they were considered to be an ancestor to modern humans. “Forty-four years after this biased classification, Neanderthals were reclassified as a human subspecies Homo sapiens Neanderthalensis and
Most of their evidence comes from the fossilized bones of Neanderthals and Cro- Magnons, or modern man’s ancestors (Shreeve, 150). There is a definite difference between their bone structures, and it may be a significant enough difference to divide them into species. There is a set of traits that distinguishes Neanderthals. Their general proportions are short, robust, and strong. Males and females of all ages have thick bones, and very pronounced muscle and ligament attachment sites. They also have distinct facial and cranial features. They have a large skull with no chin, a significant brow-ridge, and a large nasal opening (Shreeve, 49-150). They have large brains, around 1400cc, that protrude in the back, causing an occipital bun in the skull (Lecture, 4/19). Cro-Magnons on the other hand look more like humans do today. They are more slender and not as muscular, with chins and rounder skulls with slightly smaller brains among other traits.
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.
with the idea that a species as complex, sophisticated, and unique as humans shared any characteristics with Neanderthals. As the only species that celebrates the limitless quest for intellect, culture, and art, and as the most advanced species that has ever existed on this planet, surely humans dominated over such savage beasts. However, scientific evidence has proved insurmountable in uncovering the commonalties between mankind, the self-proclaimed king of the food chain, and the barbaric Neanderthals, our closest prehistoric relatives. In his article “Last of the Neanderthals” published by National Geographic in October 2008, Stephen S. Hall explores the blurred boundaries between man and Neanderthal. By visiting Neanderthal

In the early nineteenth century, fossilized remains discovered in northern European caves near the cities of Dusseldorf, Germany and Engis, Belgium led to the classification of a new species of hominin; Homo neanderthalensis, which takes its name from the Neander Valley where some of the fossils were discovered. These findings have until recently sparked much debate over its place in the lineage of our common ancestors (Smithsonian). Using information from the current fossil record the graph below illustrates the most likely common ancestor of modern humans and Neanderthals to be Homo heidelbergensis, a species of hominin which lived between 300,000 and 600,000 y.a. Fossilized remains of this species have been found as far east as India’s Narmada Valley (Pearson). A split of ancestral human and Neanderthal populations around 370,000 y.a. suggests that our evolutionary lineage continued unabated

According to Stringer and Andrews, the Out-of-Africa Model suggests that there is a fairly recent common ancestor that shares many of the anatomical characteristics displayed by modern Homo Sapiens (1263). This version is more parsimonious with regard to the fact that it ...
