And regardless of exactly how intelligent they were, their creation of these kinds of cultural artefacts is one of the defining traits of humanity.
They may even have been producing art. In one surprising discovery, the Finlaysons found a marking on the wall of Gorham's cave, dubbed the "Neanderthal hash tag". This was the first evidence of Neanderthal art, Geraldine says. Despite its crudity, Geraldine assures me that lots of preparation would have gone into it. When archaeologists tried to re-make the design themselves, they found that the deepest groove required 60 strokes of a sharp stone tool.
Further discoveries of decorative shells and the use of red ochre pigment at Neanderthal sites also points to the possibility they used objects for art. Again, if this is the case, it shows Neanderthals had symbolic abilities once thought to be uniquely human. In in Spain, more cave paintings of animals and geometric shapes were attributed to Neanderthals. This time they dated even earlier — to 64, years ago.

If they were capable of producing symbols like art and jewellery, it might not surprise you that recent studies indicate they also had sophisticated language abilities. At the time of his discovery, he said : "Many would argue that our capacity for speech and language is among the most fundamental of characteristics that makes us human. If Neanderthals also had language then they were truly human, too. If they could speak, then they could efficiently transmit information to each other, such as how to make tools.
They may even have taught us modern humans a thing or two. Finlayson says the steep cliffs on Gibraltar have helped to preserve Neanderthal remains Credit: Getty Images. There is now evidence that suggests this is exactly what happened when Neanderthals and modern humans came into contact. A type of bone tool, discovered at a known Neanderthal site, later was also found where only modern humans lived. The team, led by Marie Soressi of the University of Leiden in the Netherlands, analysed known Neanderthal sites from about , years ago.
The tools they found were actually fragments of rib bones from deer and were most likely used to help make animal hide softer, possibly for clothes. This points to one thing, she says: the modern humans who had met Neanderthals copied their use of bone tools.
Neanderthals, on the other hand, had lived in the colder European climates for many years before modern humans arrived. Learning how Neanderthals dealt with the cold would have been of great benefit to us.
Many researchers, including Soressi, now argue that meeting other early humans may therefore have been crucial for us to become the successful species we are today. Credit: BBC. That Neanderthals used many different tools again reveals how similar they were to us.
Like us, they were able to successfully adapt and exploit their environment. But there were also clear differences between Neanderthals and modern humans. It is telling that we are here today and they are not. The latter, he says, did not exploit smaller game, such as rabbits, as much as modern humans did. Though there is some evidence from Gorham's cave that Neandertals hunted rabbits, Stewart says they hunted less of them than we did.
Their close-combat hunting tactics, which had served them well for larger game, may have made it much more difficult to catch enough rabbits to sustain them when other food was in short supply.
Certainly when times got tough modern humans always had more at their disposal," he says. Climatic evidence shows that Neanderthals also were existing in an increasingly hostile environment. Extreme cold periods in other parts of Europe pushed them further south until they arrived in areas like Gibraltar.
This means that by the time the last Neanderthals reached their final place on Earth they were very inbred — bad news for a population that was already dwindling. At the same time, a finding also proposes that their fertility was declining , perhaps due to a lack of food, as infertility can be a result of decreasing body fat.
The first Neanderthal fossil was found in , but it was not recognised as a possible human ancestor until more fossils were discovered during the second half of the 19th century. Since then, thousands of fossils representing the remains of many hundreds of Neanderthal individuals have been recovered from sites across Europe and the Middle East. These include babies, children and adults up to about 40 years of age. As a result, more is known about this human ancestor than about any other.
The word neanderthalensis is based on the location where the first major specimen was discovered in — the Neander Valley in Germany. Some people refer to this species as the Neandertals with no 'h' to reflect the modern German spelling rather than the original spelling, Neanderthal, used to define the species.
Remains of this species have been found scattered across Europe and the Middle East. A study published in confirms the presence of three separate sub-groups of Neanderthals, between which slight differences could be observed, and suggests the existence of a fourth group in western Asia.
The study analysed the genetic variability, and modelled different scenarios, based on the genetic structure of the maternally transmitted mitochondrial DNA mtDNA. The study was possible thanks to the publication, since , of 15 mtDNA sequences from 12 Neanderthals.
According to the study, the size of the Neanderthal population was not constant over time and a certain amount of migration occurred among the sub-groups.
While we are closely related to the Neanderthals, they are not our direct ancestors. Evidence from the fossil record and genetic data shows they are a distinct species that developed as a side branch in our family tree. 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.
