The Neanderthal or Neandertal was a species of genus Homo (Homo neanderthalensis) that inhabited Europe and parts of western Asia from about 230,000 to 29,000 years ago (the Middle Palaeolithic and Lower Paleolithic, in the Pleistocene epoch).

Neanderthals were adapted to cold, as shown by their larger brains, short but robust builds and large nose. These traits are promoted by natural selection in cold climates, and are also observed in modern sub-arctic populations. Their brains were roughly 10 percent larger than those of modern humans. On average, Neanderthals stood about 1.65m tall (just under 5' 6") and were very muscular, comparable to modern weight-lifters.

Their characteristic style of stone tools is called the Mousterian Culture, after a prominent archaeological site where the tools were first found.

Discovery

The first Neanderthal fossils were found in August, 1856, three years before Charles Darwin's Origin of Species was published. The fossils were found in a limestone quarry near D?orf in the Neanderthal, Germany.

The type specimen, dubbed Neanderthal 1, consisted of a skull cap. Other material found were two femora, the three right arm bones, two of the left arm bones, part of the left ilium, and fragments of a scapula and ribs. They were originally thought to be bear remains by the workers who recovered it. The workers gave the material to amateur naturalist Johann Karl Fuhlrott. Fuhlrott turned the fossils over to anatomist Hermann Schaafhausen and in 1857 the discovery was jointly announced.

That discovery is now considered the beginning of paleoanthropology. These and other discoveries ultimately led to the idea that these remains were from ancient Europeans who had played an important role in modern human origins. Over 400 Neanderthals have been found since.

Name and classification

The term "Neanderthal Man" was coined in 1863 by Irish anatomist William King. Neanderthal is now spelled two ways: The spelling of the German word Thal, meaning "valley", was changed to Tal in the early 20th century, but the former spelling is retained in English and in scientific names, while the modern spelling is used in German.

The original German pronunciation (regardless of spelling) is with the sound /t/, rather than the sound /θ/ which is typical of the digraph th in English. When used in English, the term may get an anglicised /θ/ or an original /t/, depending on the speaker.

For many years, there was a vigorous professional debate about whether Neanderthals should be classified as Homo neanderthalensis or Homo sapiens neanderthalensis. The latter places Neanderthals as a subspecies of Homo sapiens; however, recent evidence from mitochondrial DNA studies indicates that Neanderthals were not a subspecies of Homo sapiens.

It is generally accepted that both Neanderthals and Homo sapiens evolved from earlier "archaic" Homo sapiens, but the classification of Neanderthals depends on when in the timeline these modern humans are considered a separate species from the "archaic" forms. This complication is introduced because the "archaic" forms are a chronospecies.

Physical traits

Compared to modern humans, Neanderthals were larger in size and had distinct morphological features, especially of the cranium, which gradually accumulated more derived aspects, particularly in certain relatively isolated geographic regions. Their relatively robust stature is thought to be an adaptation to the cold climate of Europe during the Pleistocene epoch.

The following is a list of physical traits that distinguish Neanderthals from modern humans; however, not all of them can be used to distinguish specific Neanderthal populations, from various geographic areas or periods of evolution, from other extinct humans. Also, many of these traits occasionally manifest in modern humans, particularly among certain ethnic groups. Nothing is known about the skin color, the hair, or the shape of soft parts such as eyes, ears, and lips of Neanderthals.

Language

The theory that Neanderthals lacked complex language was widespread until 1983, when a Neanderthal hyoid bone was found at the Kebara Cave in Israel. The bone that was found is virtually identical to that of modern humans. The hyoid is a small bone that holds the root of the tongue in place, and its presence seems to imply some ability to speak.

Many people believe that even without the hyoid bone evidence, it is obvious that tools as advanced as those of the Mousterian Era, attributed to Neanderthals, could not have been developed without cognitive skills encompassing some form of spoken language.

A recent study conducted on the Neanderthal hyoid found that due to the physical characteristics of Neanderthals and the fact that their Larynx would have been stouter than that of modern man, the average note emitted by Neanderthals would have been high pitched and sharper than that of modern man.

The base of the Neanderthal tongue was positioned higher in the throat, crowding the mouth somewhat. As a result, Neanderthal speech would have been slow-paced and nasalized.

Tools

Neanderthal (Middle Paleolithic) archeological sites show both a smaller and a less flexible toolkit than in the Upper Paleolithic sites, occupied by modern humans that replaced them.

There is little evidence that Neanderthals used antlers, shell, or other bone materials to make tools: their bone industry was relatively simple. However, there is good evidence that they routinely constructed a variety of stone implements. The Neanderthal (Mousterian) tool case consisted of sophisticated stone-flakes, task-specific hand axes, and spears. Many of these tools were very sharp.

Also, while they had weapons, they were not used as projectile weapons. They had spears in the sense of a long wooden shaft with an arrow head firmly attached to it, but spears were first used as projectiles by Homo sapiens.

Although much has been made of the Neanderthal's burial of their dead, their burials were less elaborate than those of anatomically modern humans. The interpretation of the Shandiar IV burials as including flowers, and therefore being a form of ritual burial (Ralph Solecki 1975), has been questioned (Sommer 1999). In some cases Neanderthal burials include grave goods such as bison and aurochs bones, tools, and the pigment ochre.

Neanderthals performed a sophisticated set of tasks normally associated with humans alone. For example, they constructed complex shelters, controlled fire, and skinned animals. Particularly intriguing is a hollowed-out bear femur with four holes in the diatonic scale deliberately bored into it. This flute was found in western Slovenia in 1995 near a Mousterian Era fireplace used by Neanderthals, but its significance is still a matter of dispute. See: prehistoric music.

Popular culture

Popular literature has tended to greatly exaggerate the ape-like gait and related characteristics of the Neanderthals. It has been determined that some of the earliest specimens found in fact suffered from severe arthritis. The Neanderthals were fully bipedal and had a slightly larger average brain capacity than a typical modern human, though it's thought the brain structure was organised differently.

In popular idiom the word Neanderthal is sometimes used as an insult, to suggest that a person combines a deficiency of intelligence and an attachment to brute force. Counterbalancing this are sympathetic literary portrayals of Neanderthals, as in the novel The Inheritors by William Golding and Jean M. Auel's Earth's Children series, or the more serious treatment by palaeontologist [[Bj?Kurt鮝], in several works including Dance of the Tiger.

Science fiction has depicted Neanderthals in several ways:
