After that point they appear to have gone physically extinct, although part of them lives on in the DNA of humans alive today. The extinction of Homo neanderthalensis is a well-known fact, but why did this species disappear after having survived for more than , years? We don't yet know. One view is that we are the reason. Early modern humans started to arrive in Europe more than 40, years ago. Perhaps Neanderthals were unable to cope with competition for resources from incoming groups of Homo sapiens.
Ancient DNA began to be recovered from Neanderthal fossils in , and this has led on to the reconstruction of several complete genomes. These indicate that Neanderthals ranging from Spain to Siberia were relatively low in numbers and diversity during their last 20, years. The genome of one female individual from the Altai Mountains also shows signs of long-term inbreeding in her population, a further indication of low numbers and isolation.
It seems that regular and sometimes extreme climatic fluctuations continually fragmented Neanderthal groups during the last , years, preventing them from building up large populations and continuous distributions across their range. Palaeoanthropologists - including Prof Chris Stringer right - search for evidence of Neanderthals at an excavation in Gibraltar.
Neanderthals did not all become extinct at the same time. Their disappearance may have been staggered, suggesting that they were replaced by early modern humans as a result of local population extinctions, rather than being quickly overrun. Rapid and dramatic climate change may have been another major factor that contributed to Neanderthals' extinction.
When severe changes in temperature happened rapidly, the plants and animals Neanderthals relied on were also affected. Faced with such conditions, only the most resourceful and adaptable could survive. Although the first Neanderthal remains were found at sites in Belgium and Gibraltar in and respectively, they weren't recognised as such until decades later.
It was the partial skeleton of a male Neanderthal unearthed during quarrying operations in the Neander Valley in Germany in that was first recognised as a distinct form of human. It was named as a new human species, Homo neanderthalensis , eight years later in It was the first ancient human species ever identified and is now known as Neanderthal 1 or Feldhofer 1, after the original name of the cave where it was found.

There's more to learn in Our Human Story. Over the past 25 years there has been an explosion of species' names in the story of human evolution. Drawing on their considerable expertise, Prof Chris Stringer and Dr Louise Humphrey have brought us an essential guide to our fossil relatives. Embark on a seven-million-year journey of evolution and see fossil and artefact discoveries in the Human Evolution gallery.
Many of us carry around two per cent Neanderthal DNA in our genes. Prof Chris Stringer discusses why and what it means. Breeding with Neanderthals allowed our ancestors to better cope with European winters, but also passed on diseases we suffer today. Unearth the one-million-year story of humans in Britain and their struggle to survive in a changing land.

By Lisa Hendry. Neanderthal facts Species: Homo neanderthalensis Lived: from about , to 40, years ago Where: across Europe and southwest and central Asia Appearance: large nose, strong double-arched brow ridge, relatively short and stocky bodies Brain size: at least 1,cm 3 to 1,cm 3 Height: about 1.
Our closest ancient human relatives Neanderthals were humans like us, but they were a distinct species called Homo neanderthalensis. When did Neanderthals live? Where did Neanderthals live? What did Neanderthals look like? Neanderthal intelligence and behaviour Despite their reputation as being primitive 'cavemen', Neanderthals were actually very intelligent and accomplished humans.

Neanderthals vs Homo sapiens Because many Neanderthal fossils and artefacts have been found in caves, the species became synonymous with the idea of cavemen. Did Neanderthals make art? What did Neanderthals eat? Could Neanderthals speak? Why did Neanderthals go extinct? When were Neanderthals discovered? Cast of the cranium of Neanderthal 1, the first fossil recognised as Neanderthal.
Some European Homo heidelbergensis fossils were showing early Neanderthal-like features by about , years ago and it is likely that Neanderthals evolved in Europe from this species. The name Homo sapiens neanderthalensis was once common when Neanderthals were considered to be members of our own species, Homo sapiens. This view and name are no-longer favoured. Groundbreaking analysis of the Neanderthal genome nuclear DNA and genes published in shows that modern humans and Neanderthals did interbreed, although on a very limited scale.
This suggests that modern humans bred with Neanderthals after moderns left Africa but before they spread to Asia and Europe. The most likely location is the Levant, where both species co-existed for thousands of years at various times between , years ago. Interestingly, the data doesn't support wide-scale interbreeding between the species in Europe, where it would have been most likely given their close proximity.
Researchers are now questioning why interbreeding occurred on such a low scale, given that it was biologically possible. The answer may lie in cultural differences. Did the Neanderthals also live alongside another human species in Europe?
An interesting case making headlines in was the discovery of a finger bone and tooth from Denisova cave in Russia. The bones were found in and date to about 30,, years old. Little else could be gleaned from these studies so scientists started work on extracting nuclear DNA. This produced far more information. The 'Denisovians', as they have been nicknamed, were more closely related to Neanderthals than modern humans. This suggests the Neanderthals and 'Denisovans' shared a common ancestor after modern humans and Neanderthals split.
Perhaps this ancestor left Africa half a million years ago with the Neanderthals spreading west to the Near East and Europe while the Denisovans headed east.
However, this does not necessarily mean they are a 'new' species as they may be already known from fossils that have no DNA record to compare, such as Homo heidelbergensis or H. See Nature, December s. Neanderthals are recognisably human but have distinctive facial features and a stocky build that were evolutionary adaptations to cold, dry environments. Evidence shows that Neanderthals had a complex culture although they did not behave in the same ways as the early modern humans who lived at the same time.
Scholars debate the degree of symbolic behaviour shown by Neanderthals as finds of art and adornment are rare, particularly when compared to their modern human contemporaries who were creating significant amounts of cave paintings, portable art and jewellery. Some researchers believe they lacked the cognitive skills to create art and symbols and, in fact, copied from or traded with modern humans rather than create their own artefacts.
However, others suggest the scarcity may have been due to social and demographic factors. The Neanderthals had a reasonably advanced tool kit classified as Mode 3 technology that was also used by early members of our own species, Homo sapiens.
This was also known as the Mousterian, named after the site of Le Moustier. At the end of their long history in Europe, they began manufacturing a more refined toolkit known as the Chatelperronian , similar to the blade tools of Homo sapiens.
This occurred at about the same time as modern humans entered Europe. Many archaeologists think that the Neanderthals were attempting to copy the types of tools that they observed modern humans making.
Alternatively, they may have obtained these tools by trading with the modern humans. The Neanderthals built hearths and were able to control fire for warmth, cooking and protection. They were known to wear animal hides, especially in cooler areas. However, there is no physical evidence that Neanderthal clothing was sewed together, and it may have simply been wrapped around the body and tied. Neanderthals left behind no known symbolic art and only limited evidence for body decoration.
One of few decorative items found at a Neanderthal site is a pendant from Arcy-sur-Cure in France, found amongst bone tools and other artefacts that were attributed to a culture known as Chatelperronian which most researchers consider Neanderthal. However, redating of the site's layers in suggest contamination occurred between layers and that the artefact may have been made by modern humans, as they also occupied this site in later times.
There is only one other undisputed Chatelperronian site that has yielded personal ornaments, and even these may have been obtained by trade with modern humans Homo sapiens , or been made in imitation of artefacts made by modern humans. In researchers uncovered artefacts at two sites in Spain - Anton rock shelter and Aviones cave - that provide indirect evidence of symbolic art.
The former held naturally-perforated scallop shells painted with orange pigments and the latter a cockleshell that may have been used as a paint container as it had residue of red and black pigments. The Avione finds date to between , years ago, which is before modern humans arrived in Europe so could not have been copied from them. The dead were often buried, although there is no conclusive evidence for any ritualistic behaviour. However, at some sites, objects have been uncovered that may represent grave goods.
This species occupied a range of environments across Europe and the Middle East and lived through a period of changing climatic conditions. Ice Ages in Europe were interspersed with warmer periods but by , years ago average temperatures were on the decline and full glacial conditions had appeared by 40, years ago. There is evidence that the Neanderthals hunted big game and chemical analysis of their fossils shows that they ate significant amounts of meat supplemented with vegetation.
Despite this mixed diet, nearly half of the Neanderthal skeletons studied show the effects of a diet deficient in nutrients. Researchers have long debated whether Neanderthals also included human meat in their diets. It is not always easy to determine if cut marks on human bones are due to cannabilism, some other practice or even animal teeth, but in recent years new evidence has emerged that suggests some Neanderthals may indeed have been cannibals on occasions. Neanderthals persisted for hundreds of thousands of years in extremely harsh conditions.
They shared Europe for 10, years with Homo sapiens. Today they no longer exist. Beyond these facts the fate of Neanderthals has generated much debate.
Theory 1: They interbred with Homo sapiens sapiens on a relatively large scale. Followers of this theory believe that although Neanderthals as organisms no longer exist their genes were present in early modern Europeans and may still exist today. Neanderthals were a sub-species of Homo sapiens rather than a separate species and hence their scientific name is Homo sapiens neanderthalensis.
Theory 2: They were essentially replaced by Homo sapiens. In this case, Neanderthals are a separate species from Homo sapiens. This model does allow for peripheral interbreeding but no significant genetic input from Neanderthals to modern Europeans. Today, most theories accept that Neanderthals displayed advanced behaviours and adaptive strategies and were not sluggish brutes that stood no chance against the vastly superior Homo sapiens.
However,the incoming Homo sapiens were doing something that was different enough, and just that little bit more superior, to give them an edge under the circumstances. Exactly what was 'a little bit more superior' is debated. Of particular interest are a number of new studies that focus on the role of climate change and the subtle differences that behaviour and biology play in these conditions. The Australian Museum respects and acknowledges the Gadigal people as the First Peoples and Traditional Custodians of the land and waterways on which the Museum stands.

Like other humans, Neanderthals originated in Africa but migrated to Eurasia long before other humans did. Neanderthals lived across Eurasia, as far north and west as the Britain, through part of the Middle East, to Uzbekistan. Popular estimates put the peak Neanderthal population around 70,, though some scientists put the number drastically lower , at around 3, females. Their short, stocky stature was an evolutionary adaptation for cold weather, since it consolidated heat.
According to the Smithsonian Institution, the wide nose helped humidify and warm cold air, though this assertion is debated. The American Museum of Natural History states that other differences from other humans are a flaring, funnel-shaped chest, a flaring pelvis, and robust fingers and toes. Approximately 1 percent of Neanderthals had red hair , light skin, and maybe even freckles.
Their brains, however, grew at slower rate than the brains of other humans' and became larger, according to research published in the September issue of the journal Science. Neanderthals lived in nuclear families. Discoveries of elderly or deformed Neanderthal skeletons suggest that they took care of their sick and those who could not care for themselves. Neanderthals typically lived to be about 30 years old, though some lived longer. It is accepted that Neanderthals buried their dead, though whether or not they left carved bone shards as grave goods is debated.
It is not known if they had language, though the large size and complex nature of their brains make it a likely possibility. Neanderthals used stone tools similar to the ones used by other early humans, including blades and scrapers made from stone flakes. As time went on, they created tools of greater complexity, utilizing materials like bones and antlers.
Evan Hadingham of PBS's NOVA reported that Neanderthals used a type of glue, and later pitch, to attach stone tips to wooden shafts, creating formidable hunting spears.
Neanderthals had some control of fire, and it is even theorized that they built boats and sailed on the Mediterranean. Neanderthals were primarily carnivorous, and the harsh climate caused them to resort occasionally to cannibalism.
