The evolution of neanderthals essay

The sites from which this speciess is known, which are predominantly cave sites, date from roughly thousand years ago ka to as late as roughly 30 ka. In addition to points, these technique was also used to create other tools—particularly, many different kind of scrapers.

That is, the skeleton is short and wide to minimize surface area thereby minimizing heat loss while maintaining the same mass. The fossil record of Homo neanderthalensis is large and this extensive record has allowed scientists to make interesting inferences about the lifesryle of this species using evidence gleaned from the skeleton.

Some researchers suggestb they may have been part of a mate recognition system. Teeth have also been used to study the growth and development of this species. For example, Neanderthal cave sites often contain hearths and it is likely that this individuals of this species used animal hides to insulate themselves from cold temperatures.

This issue is dealt with in greater detail elsewhere see essay on Homo sapiensbut the general consensus is that Homo neanderthalensis was a separate species from Homo sapiens and that, although some interbreeding may have occurred, Homo neanderthalensis did not make a lasting genetic contribution to Homo sapiens.

Homo neanderthalensis displays many unique features, including features in the skull and postcranial skeleton skeleton minus skullwhich are related to their adaptation to hunting large game in cold environments.

Explore human lineage through time: These features of the postcranial skeleton are similar to those seen in other mammals that live in cold environments. The mandibles lower jaws are also large and bear molar teeth with large pulp chambers the area below the enamel in which nerves and blood vessels reside.

In addition, these tools are almost always produced using the same techniques used by Homo neanderthalensis to make other tools. September 30, Homo neanderthalensis Remains of Homo neanderthalensis have been found at sites throughout Europe, as well as in western Asia.

As with Homo erectus, the general shape of the Homo neanderthalensis skull is long and low with large browridges. This controversy largely involves the relationship of this taxon and Homo sapiens. Researchers suggest that these fractures are related to hunting dangerous prey at close range.

Other scientists have suggested that midfacial prognathism was a mechanism to increase the size of the sinuses in order to warm the air in the cold environments in which Homo neanderthalensis lived. Indeed, the brains of Homo neanderthalensis were bigger than those of Homo sapiens; when judged in relation to body size see belowhowever, the brain of Homo neanderthalensis is slightly smaller than that of Homo sapiens.

The evidence for symbolic artifacts—e. The nasal aperture hole for the nose in Homo neanderthalensis is large, especially when compared to those of Homo sapiens. This evidence suggests that the ranges of Neanderthal populations were intermediate between those of Homo erectus and Homo sapiens.

The Homo neanderthalensis skull is quite large, with brain sizes averaging over cubic centimeters cc. Homo neanderthalensis also had sophisticated stone tool technologies designed to hunt large mammals at close range.

This position is corroborated by the fact that these tools are normally found at Homo neanderthalensis sites that were close to and contemporary with Homo sapiens sites.

This hypothesis is consistent with the large degree of wear on the front teeth, which might also indicate the use of these teeth as tools in hide working or other tasks. The limb bones were short and the distal segments of the limbs the bones of the forearm and lower leg were particularly short.

However, Homo neandethalensis also made non-prepared core tools.

This technique involves removing flakes from a core source rock in order to produce a flake a chip of stone removed from a core of a desired shape. This species is important to human evolution because it was contemporary with Homo sapiens and is therefore crucial to our understanding of the origin of our species.

Because the widest point of the cranium skull minus lower jaw is across the middle of the braincase, the skull of H.

Important inferences can also be drawn from skull fossils of Homo neanderthalensis. Many of the unique features possessed by H. Unlike those of H.

Individuals were short compared to modern humans; their bodies were also wider, with wider shoulders, rib cages, and hips. Consensus regarding the evolutionary relationships between Homo neanderthalensis and other hominin species has not been reached.

Homo neanderthalensis also produced stone tools that closely resemble those made by contemporary Homo sapiens in Europe.

Thus, it seems more likely that these tools are the result of Homo neanderthalensis copying the end-products of Homo sapiens stone tool technology, rather than an independent invention. The Neanderthal postcranial skeleton also exhibits unique features.

Other scientists, however, suggest that these differences are more minor and may overlap with the variation found in modern humans.Proof that Humans Interbred with Neanderthals Essay - Over the last few hundred years, more and more has been added to the world’s fossil collection, fossils from all over the world.

New theories have been created and old theories have almost been proven about the evolution of man. Throughout time man has evolved. Common belief is that Homo sapiens evolved from primates and then, by following the Darwinistic theory of evolution, Neanderthals, when in fact they all evolved alongside each other, sharing common ancestors rather than directly coming from one another.

The Neanderthals were hominids (erect primates) who existed throughout the Middle Paleolithic Age (also called the Mesolithic Period), aboutto 33, B.C.

A number of scientists presently regard Neanderthals as the ancestors of humans. Darwinistic Theory of Evolution: Neanderthals vs. Humans Essay Words | 3 Pages evolved from primates and then, by following the Darwinistic theory of evolution, Neanderthals, when in fact they all evolved alongside each other, sharing common ancestors rather than directly coming from one another.

Darwinistic Theory of Evolution: Neanderthals vs. Humans Essay They also happened to show additional similarities to the Neanderthal than any other modern human DNA sample. However, this was probably due to the fact that once the ancient Homo sapien people travelled to Australia, they were essentially cut off from everyone else given.

This issue is dealt with in greater detail elsewhere (see essay on Homo sapiens), but the general consensus is that Homo neanderthalensis was a separate species from Homo sapiens and that, although some interbreeding may have occurred, Homo neanderthalensis did not make a lasting genetic contribution to Homo sapiens.
