What if neanderthals had survived




















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.

Skip to main content Skip to acknowledgement of country Skip to footer Le Moustier Homo neanderthalensis skull side view. The distinctive features of Neanderthals are already apparent in this adolescent individual. This was the first Neanderthal skull ever found. Its significance was not realised until , after the discovery and publication of another Neanderthal skull discovered in the Neander Valley in Germany in Unfortunately, the exact provenance of the Gibraltar skull is uncertain so it has yet to be accurately dated.

The skull is one of the best-preserved Neanderthal crania found and is probably a female. Its age is 45, years old. The features and skull shape — particularly the brow ridge, nose, jaw and back of the skull — of this Middle Eastern Neanderthal are much less robust and the skull bone thinner compared to European specimens such as La Chapelle-aux-Saints. This is probably due to the Middle Eastern Neanderthal population having evolved adaptations to the warmer climate.

Background on discovery. Age This species lived between 28, and , years ago early Homo neanderthalensis from about , years ago classic Homo neanderthalensis from about , years ago late Homo neanderthalensis from about 45, years ago. Important fossil discoveries 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.

Prof Stringer says, 'So far, in my opinion, we don't have representational art from Neanderthal sites. But they did exhibit a degree of symbolism - they made jewellery. Some of this jewellery was apparently fashioned from eagle talons. The oldest examples are about , years old. Pierced animal teeth and worked ivory have been found at Neanderthal sites such as the Grotte du Renne cave in France.

Neanderthals probably also used pigment to decorate or camouflage their bodies. A study published in Science in found evidence that some Palaeolithic artwork in Spain was made by Neanderthals, as they dated to a time long before modern humans were in the region.

Created using red pigment, the Spanish cave paintings included hand stencils and geometric shapes. The Spanish cave art indicates that Neanderthals were in fact capable of symbolic or artistic expression.

Prof Stringer adds, 'They further narrow any perceived behavioural gap between the Neanderthals and us. However, there are still no clear examples of Neanderthals creating representational art copied from real sources such as animals or people. The typical image of Neanderthals is of highly carnivorous, ice-age hunters and scavengers who ate large mammals.

However, food remains preserved in the calculus hardened tartar around their teeth show that the Neanderthal diet also included various plants, either collected directly or from eating the stomach contents of their plant-eating prey. Neanderthals also ate fungi. In Gibraltar, they consumed mussels, young seals and perhaps also dolphin, though that meat may have been sourced from scavenged carcasses.

Part of a seal jaw found in Vanguard cave in Gibraltar. Researchers found evidence - such as cutmarks from tools - that Neanderthals processed marine animals for food. Although Neanderthals were able to use fire, whether they regularly cooked their food is unclear.

It's very difficult to determine whether Neanderthals had spoken language as the tissue associated with the voice box doesn't preserve. However, they did have a similar vocal anatomy and their ear bones suggest they had a similar range of hearing to us. The complexity of their social lives also suggests they must have been able to talk to each other, although their language may have been simpler than ours. The most recent fossil and archaeological evidence of Neanderthals is from about 40, years ago in Europe.

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.

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.

You must be over the age of Privacy notice. But in the modern origin story, evolution, there's no defining moment of creation. Instead, humans emerged gradually, generation by generation, from earlier species. Just like any other complex adaptation — a bird's wing, a whale's fluke, our own fingers — our humanity evolved step by step, over millions of years. Mutations appeared in our DNA, spread through the population, and our ancestors slowly became something more like us and, finally, we appeared.

People are animals, but we're unlike other animals. We have complex languages that let us articulate and communicate ideas. We're creative: we make art, music, tools. Our imaginations let us think up worlds that once existed, dream up worlds that might yet exist, and reorder the external world according to those thoughts.

Our social lives are complex networks of families, friends and tribes, linked by a sense of responsibility towards each other. We also have an awareness of ourselves, and our universe: sentience, sapience, consciousness, whatever you call it. And yet the distinction between ourselves and other animals is, arguably, artificial. Animals are more like humans than we might like to think.

That's especially true of the great apes. Chimps, for example, have simple gestural and verbal communication. They make crude tools, even weapons , and different groups have different suites of tools — distinct cultures.

Chimps also have complex social lives, and cooperate with each other. As Charles Darwin noted in The Descent of Man , almost everything odd about Homo sapiens— emotion, cognition, language, tools, society — exists, in some primitive form, in other animals.

We're different, but less different than we think. In the past, some species were far more like us than other apes — Ardipithecus , Australopithecus , Homo erectus and Neanderthals. Homo sapiens are the only survivors of a once diverse group of humans and human-like apes, collectively known as the hominins.

It is a group that includes around 20 known species and probably dozens of as yet unknown species. The extinction of other hominins, however, has helped to create the impression of a vast, unbridgeable gulf that separates our species from the rest of life on Earth.

But the division would be far less clear if those species still existed. What looks like a bright, sharp dividing line is really an artefact of extinction. The discovery of these extinct species now blurs that line again and shows how the distance between us and other animals was crossed — gradually, over millennia. Our lineage probably split from the chimpanzees around six million years ago.

These first hominins, members of the human line, would barely have seemed human, however. For the first few million years, hominin evolution was slow.

The first big change was walking upright , which let hominins move from forests into more open grassland and bush.

But if they walked like us, nothing else suggests the first hominins were any more human than chimps or gorillas. Ardipithecus , the earliest well-known hominin, had a brain that was slightly smaller than a chimp's , and there's no evidence they used tools. In the next million years, Australopithecus appeared. Australopithecus had a slightly larger brain — larger than a chimp's, but still smaller than a gorilla's. It made slightly more sophisticated tools than chimps, using sharp stones to butcher animals.

Then came Homo habilis. For the first time, hominin brain size exceeded that of other apes. Tools — stone flakes, hammer stones, "choppers" — became much more complex.

After that, around two million years ago, human evolution accelerated, for reasons we're yet to understand. At this point, Homo erectus appeared. Erectus was taller, more like us in stature, and had large brains — several times bigger than a chimp's brain, and up to two-thirds the size of ours. They made sophisticated tools , like stone handaxes. This was a major technological advance. Handaxes needed skill and planning to create, and you probably had to be taught how to make one.

It may have been a metatool — used to fashion other tools , like spears and digging sticks. Like us, Homo erectus had small teeth. That suggests a shift from plant-based diets to eating more meat, probably obtained from hunting. It's here that our evolution seems to accelerate. The big-brained Erectus soon gave rise to even larger-brained species.

These highly intelligent hominins spread through Africa and Eurasia, evolving into Neanderthals , Denisovans , Homo rhodesiensis and archaic Homo sapiens.
