Why is neanderthal important

Abnormal wear in his right knee, ankle and foot shows that he suffered from injury-induced arthritis that would have made walking painful, if not impossible. Neanderthals inhabited a vast area roughly from present-day England east to Uzbekistan and south nearly to the Red Sea. Their time spanned periods in which glaciers advanced and retreated again and again.

But the Neanderthals adjusted. When the glaciers moved in and edible plants became scarcer, they relied more heavily on large, hoofed animals for food, hunting the reindeer and wild horses that grazed the steppes and tundra. Paleoanthropologists have no idea how many Neanderthals existed crude estimates are in the many thousands , but archaeologists have found more fossils from Neanderthals than from any extinct human species.

The first Neanderthal fossil was uncovered in Belgium in , though nobody accurately identified it for more than a century. In , the Forbes Quarry in Gibraltar yielded one of the most complete Neanderthal skulls ever found, but it, too, went unidentified, for 15 years. Over the years, France, the Iberian Peninsula, southern Italy and the Levant have yielded abundances of Neanderthal remains, and those finds are being supplemented by newly opened excavations in Ukraine and Georgia.

Clues to some Neanderthal ways of life come from chemical analyses of fossilized bones, which confirm that Neanderthals were meat eaters. Microscopic studies hint at cannibalism; fossilized deer and Neanderthal bones found at the same site bear identical scrape marks, as though the same tool removed the muscle from both animals.

The arrangement of fossilized Neanderthal skeletons in the ground demonstrates to many archaeologists that Neanderthals buried their dead. Paleoanthropologists generally agree that Neanderthals lived in groups of 10 to 15, counting children.

That assessment is based on a few lines of evidence, including the limited remains at burial sites and the modest size of rock shelters. Also, Neanderthals were top predators, and some top predators, such as lions and wolves, live in small groups.

The typical Neanderthal tool kit contained a variety of implements, including large spear points and knives that would have been hafted, or set in wooden handles. Other tools were suitable for cutting meat, cracking open bones to get at fatrich marrow or scraping hides useful for clothing, blankets or shelter. Yet other stone tools were used for woodworking; among the very few wooden artifacts associated with Neanderthal sites are objects that resemble spears, plates and pegs.

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. For the last years, then, it was a numbers game. Their population may have become so small that eventually they reached "a point of no return".

Unfortunately, this means that although the last Neanderthals were living in much the same way as their ancestors had done for many years before them, climatic changes meant that it was not enough to ensure their survival.

If life only becomes a battle for survival, other things like culture may fall by the wayside. In their last years on Earth, it would not have taken much competition from other humans, animals or disease to finish them off. But while their species is said to be extinct, they are not entirely gone. Large parts of their genome still lives on in us today. The last Neanderthals may have died — but their stamp on humanity will be ensured for thousands of years to come.

But four caves in Gibraltar have given an unprecedented insight into what their lives might have been like.

Kissing cousins Like the rest of their species, the Neanderthals who lived here were far from what we once pictured — a brutish, stocky group of primitive humans who could only grunt to communicate and violently wield their clubs before anyone who got too close.

From African hominins of 2 million years The Stone Age marks a period of prehistory in which humans used primitive stone tools. Lasting roughly 2. During the Stone The prehistoric reptiles known as dinosaurs arose during the Middle to Late Triassic Period of the Mesozoic Era, some million years ago.

The Fertile Crescent is the boomerang-shaped region of the Middle East that was home to some of the earliest human civilizations. The Cretaceous-Tertiary extinction event, or the K-T event, is the name given to the die-off of the dinosaurs and other species that took place some For many years, paleontologists believed this event was caused by climate and geological changes that The Neolithic Revolution, also called the Agricultural Revolution, marked the transition in human history from small, nomadic bands of hunter-gatherers to larger, agricultural settlements and early civilization.

The Neolithic Revolution started around 10, B. An ice age is a period of colder global temperatures and recurring glacial expansion capable of lasting hundreds of millions of years. Thanks to the efforts of geologist Louis Agassiz and mathematician Milutin Milankovitch, scientists have determined that variations in the The Bronze Age marked the first time humans started to work with metal.

Bronze tools and weapons soon replaced earlier stone versions. Humans made many technological advances during the Live TV. This Day In History. History Vault. There is evidence that Neanderthals deliberately buried their dead and occasionally even marked their graves with offerings, such as flowers.

No other primates, and no earlier human species, had ever practiced this sophisticated and symbolic behavior. DNA has been recovered from more than a dozen Neanderthal fossils, all from Europe; the Neanderthal Genome Project is one of the exciting new areas of human origins research. Neanderthal 1 was the first specimen to be recognized as an early human fossil. When it was discovered in in Germany, scientists had never seen a specimen like it: the oval shaped skull with a low, receding forehead and distinct browridges, the thick, strong bones.

In , it became the first fossil hominin species to be named. Several years after Neanderthal 1 was discovered, scientists realized that prior fossil discoveries—in at Engis, Belgium, and in at Forbes Quarry, Gibraltar—were also Neanderthals. Compared to early humans living in tropical Africa, with more abundant edible plant foods available year-round, the number of plant foods Neanderthals could eat would have dropped significantly during the winter of colder climates, forcing Neanderthals to exploit other food options like meat more heavily.

There is evidence that Neanderthals were specialized seasonal hunters, eating animals were available at the time i. Scientists have clear evidence of Neanderthal hunting from uncovering sharp wooden spears and large numbers of big game animal remains were hunted and butchered by Neanderthals. There is also evidence from Gibraltar that when they lived in coastal areas, they exploited marine resources such as mollusks, seals, dolphins and fish. Scientists have also found plaque on the remains of molar teeth containing starch grains—concrete evidence that Neanderthals ate plants.

The Mousterian stone tool industry of Neanderthals is characterized by sophisticated flake tools that were detached from a prepared stone core. This innovative technique allowed flakes of predetermined shape to be removed and fashioned into tools from a single suitable stone. Acheulean tools worked from a suitable stone that was chipped down to tool form by the removal of flakes off the surface. Neanderthals used tools for activities like hunting and sewing. Left-right arm asymmetry indicates that they hunted with thrusting rather than throwing spears that allowed them to kill large animals from a safe distance.

Neanderthal bones have a high frequency of fractures, which along with their distribution are similar to injuries among professional rodeo riders who regularly interact with large, dangerous animals. Scientists have also recovered scrapers and awls larger stone or bone versions of the sewing needle that modern humans use today associated with animal bones at Neanderthal sites. A Neanderthal would probably have used a scraper to first clean the animal hide, and then used an awl to poke holes in it, and finally use strips of animal tissue to lace together a loose-fitting garment.

Neanderthals were the first early humans to wear clothing, but it is only with modern humans that scientists find evidence of the manufacture and use of bone sewing needles to sew together tighter fitting clothing. Neanderthals also controlled fire, lived in shelters, and occasionally made symbolic or ornamental objects.

This may be one of the reasons that the Neanderthal fossil record is so rich compared to some earlier human species; being buried greatly increases the chance of becoming a fossil!
