The use of stone tools by our ancient ancestors was, until now, thought to have originated with the Homo genus around 2.6 million years ago. But the discovery of a collection of implements in Kenya, which predate this by a staggering 700,000 years, could rewrite what we know about early human history.

Researchers believe the 3.3-million-year-old stones - including anvils, hammers and cores - were made by a undetermined hominin species which had a 'strong grip and good motor control'.

Stone-tool culture associated with Homo has been dated back to around 2.6 million years ago and this was based on evidence found in Ethiopia.

In particular, artefacts were found near the remains of one of the earliest Homo fossils, Homo habilis, also known as 'the handy man', and this culture is described as Oldowan.

WHO MADE THE ANCIENT TOOLS?
While the researchers said they can't currently be sure who made the tools, an earlier find of a skull suggests it may have been Kenyanthropus platytops - a hominin living 3.3 million years ago.

This is because the skull was found in 1999 less than a mile (1km) from the tool site.
The precise family tree of modern humans is contentious, and so far, no one knows exactly how K. platyops relates to other hominin species, although Kenyanthropus predates the earliest known Homo species by a half a million years.

This species could have made the tools, or the toolmaker could have been some other species from the same era, such as Australopithecus afarensis, or an as-yet undiscovered early type of Homo, the researchers say.

The new tools, unearthed from the Lomekwi 3 site next to Lake Turkana in Kenya, predate these Oldowan tools by around 700,000 years, according to lead researcher Sonia Harmand from Stony Brook University in New York.


Professor Harmand and colleagues from Hebrew University in Jerusalem said the collection, which additionally includes worked cobbles, is more primitive than that found in Ethiopia but would have been made by a group with the 'cognitive capabilities of early relatives of humans.' Img credit: Nature

[...]

The finds add to a growing belief that pre-human forms exhibited ‘human’ behaviour and seem to challenge the notion that our most direct ancestors were the first to bang two rocks together to create a new 'technology'.

The tools are the first piece of evidence that an even earlier group of proto-humans may have had the thinking abilities needed to figure out how to make sharp-edged tools and mark ‘a new beginning to the known archaeological record’ according to the study, published in the Nature journal.

‘The whole site’s surprising, it just rewrites the book on a lot of things that we thought were true,’ said Chris Lepre of the Lamont-Doherty Earth Observatory and Rutgers University, a co-author of the paper who precisely dated the artefacts.

Professor Sonia Harmand and her colleagues from Hebrew University in Jerusalem said the collection includes anvils, hammer stones, worked cobbles and cores (two example cores are pictured with a flake)

WHY IS THE FIND IMPORTANT?
The find of more than 100 tools adds to a growing belief that pre-human forms exhibited ‘human’ behaviour and seem to challenge the notion that out most direct ancestors were the first to bang two rocks together to create a new technology.

They were crafted long before modern humans, probably by some sort of human ancestor and push the known date of handheld tools back by 700,000 years.

The tools are the first piece of evidence that an even earlier group of proto-humans may have had the thinking abilities needed to figure out how to make sharp-edged tools and mark ‘a new beginning to the known archaeological record’ according to the study.

Experts claim to find preserved skin tissue on a 2 MILLION-year-old fossil - that would be the oldest in the world folks

Have scientists unearthed the world's oldest human SKIN? Preserved tissue found on a 2 MILLION-year-old fossil, expert claims
-South African anthropologists believe they have found preserved skin that belonged to an early human species known as Australopithecus sediba
-It could be the oldest soft tissue ever found for an early human species
-Scientists say they also discovered food particles in the teeth of the fossils
-The fossils were discovered in Malapa Nature Reserve near Johannesburg

[Fossilized] skin belonging to a prehistoric human ancestor that lived two million years ago is thought to have been discovered among the remains of six skeletons.

Anthropologists believe they have found the preserved skin tissue of an early human species known as Australopithecus sediba in an ancient cave near Johannesburg, in South Africa. It could be the oldest example of human soft tissue to ever be found and is set to reveal new details about what this now extinct species of human was like.

Scientists who have been leading the excavation, which began with the discovery of the remains of a 4ft 2 inch tall male juvenile in 2008, believe they have also found the remains of the ancient humans' last meals still preserved in their teeth. They say seeds and other food particles that became stuck in the creatures' teeth have been preserved.

Professor Lee Berger, an anthropologist at the University of Witwatersrand in Johannesburg, who has been leading the excavation, said: 'We found out this wasn't just a normal type of rock that they were contained in - it was a rock that was preserving organic material.

'Plant remains are captured in it - seeds, things like that - even food particulates that are captured in the teeth, so we can see what they were eating. 'Maybe more remarkably, we think we've found fossil skin here too.'

Professor Berger, who made his comments in an interview with the Naked Scientists, discovered the first remains of Australopithecus sediba in 2008 after his son Matthew stumbled upon a [sic] fossilised bone in the Malapa Nature Reserve near Johannesburg.

They later excavated an almost complete skull, together with shoulder bones, a hand, wrist bones and ankle bones. Professor Berger announced the discovery to the world in 2010.
He described the early human as a new species that he called Australopithecus sediba and is thought to be a transitional species between earlier Australopithecus species and early Homo species...

AUSTRALOPITHECUS SEDIBA - A PIGEON-TOED CLIMBER
Research on the fossils of Australopithecus sediba have given an unprecidented insight into what these early human ancestors were like.

The fossils, which were studied by scientists across the world, show a mixture of primitive features and of more advanced features typical of later human species.

It has a narrow upper rib cage while the modern human's thorax is uniformly cylindrical. The cone-shaped rib cage allowed the early hominin to move its shoulder blades so it could climb trees. However, this prevented A. sediba from swinging its arms, meaning that walking and running was much more difficult. It had a slim waist similar to modern humans but feet which turned sharply inwards.

A. sediba had the same number of lumbar vertebrae as a modern man and a similar curvature of the lower back. However, its back was longer and more flexible than that of modern humans.
They had longer arms than we do with curved fingers, which would have made them adept at climbing.

The researchers also hope to find out whether, if it is soft tissue, it had been dried or soaked in water as it was preserved in the rock.

The remains of plants and insects have also been found preserved in the cement-like breccia alongside the skeletons.

It is thought that sediment in the bottom of a pool of water may have helped to protect the organic material from bacteria that would have caused them to rot and break down.
Professor Berger and his team are now trying to create a live laboratory on top of the site so they can continue working on the fossils while they are still in the ground without damaging them.

The laboratory will also have a platform that will allow members of the public to look down into the site where the remains are being excavated...

New study suggests the ancient Egyptians cared for domesticated cats as long ago as 5700 years ago

     In brief:
     --Researchers from the Royal Belgian Institute of Natural Sciences said a cat skeleton     
     indicates humans cared for cats in 3,700BC
     --It's long been thought cats were first domesticated by the Egyptians, but a recent study 
     found Chinese farmers also kept them as pets in 3,300BC
     --DNA studies suggest most domestic cats today are descendants of the near eastern 
     wildcat, which still lives in northern Africa and the Middle East
----------------------------------------------------------------------------------------------------------------------------------
Dogs may be known as man’s best friend, but cats have also been enjoying the company of humans for longer than previously thought.

The skeleton of a cat believed to have been cared for by humans indicates that the ancient Egyptians kept felines as pets in 3,700BC. It has long been thought cats were first domesticated by the Egyptians, but a recent study found that Chinese farmers also kept them as pets as long ago as 3,300BC.

The skeleton of a cat believed to have been cared for by humans indicates that the ancient Egyptians kept felines as pets in 3,700BC. DNA studies suggest that most of the 600million domestic cats today are descendants of the near eastern wildcat (pictured), which still lives in northern Africa and the Middle East

Until recently, it was thought that cats were first domesticated in ancient Egypt in around 1,950BC, but this new research sheds new light on humans’ relationship with cats. ‘It is clear that there was a close relationship with humans that predate the oldest accepted evidence for domestic cat in Egypt by almost two millennia,’ said Wim Van Neer of the Royal Belgian Institute of Natural Sciences, who led the study published in the Journal of Archaeological Science.

The discovery at the crux of their study was a group burial at the cemetery of Hierakonpolis, which was once a large city predating the pyramids, Pacific Standard reported. Skeletons dating from 3,700BC included a small jungle cat, with a healed bone fracture, indicating it had ‘been tended to for several weeks prior to its sacrifice,’ according to the archaeologists.

They believe the find proves that the cat was domestic – at least for the latter part of its life and measurements of the bones strengthen their case. The same cemetery also yielded another six cats, which were apparently killed as part of a religious ritual. The cats came from three or four different litters.

‘If all these animals are supposed to be taken from the wild, four different captures must be accepted. It seems unlikely that sufficient opportunities for successful capture would have occurred in a short period of time prior to the sacrifice. For that reason, it seems that at least some of the cats may have been kept in captivity prior to the burial,’ they wrote.

While there is a chance that the cats were wild but lived nearby the human settlement, the researchers believe that felines still had a close connection with humans over five millennia ago.

It was announced in December that the bodies of cats found at a dig at a village in Shaanxi province in central China dated back 5,300 years – re-writing cats and humans’ joint history.
Dr Fiona Marshall, of Washington University in St Louis said analysis including radiocarbon dating of bones suggested the cats preyed on rodents that lived on farmed millet.

These cat mummies date from the first century AD and are 

associated with the goddess Bastet

The team analysed eight bones from at least two cats excavated from the site. One of the cats had old bones - suggesting it had survived well into old age in the village. Another was shown to have eaten fewer animals and more millet than expected, suggesting it had been fed by the villagers. Dr Marshall, who studied the site with scientists from Chinese universities, suggested that the cats were domesticated to control the villagers’ rat problem.

Our data suggests that cats were attracted to ancient farming villages by small animals, such as rodents that were living on the grain that the farmers grew, ate and stored,' she said. ‘Results of this study show that the village of Quanhucun was a source of food for the cats 5,300 years ago, and the relationship between humans and cats was commensal, or advantageous for the cats.

‘Even if these cats were not yet domesticated, our evidence confirms that they lived in close proximity to farmers, and that the relationship had mutual benefits.’ DNA studies suggest that most of the estimated 600million domestic cats around the world today are descendants of the near eastern wildcat, which still lives in northern Africa and the Middle East.

Our human ancestors made cheese & dairy products over 7,000 years ago

HUMANS MILKED COWS OVER 7,000 YEARS AGO
Milk products may be why the hunter-gatherer lifestyle was given up in favor of a more settled, and yogurt-eating, existence.

THE GIST

• People were processing dairy products in the African Sahara more than 7,000 years ago.
• The first dairy farmers lived in Anatolia, now modern-day Turkey.
• Dairy farming may have pushed people to settle down.

More than 7,000 years ago, prehistoric people in the African Sahara were making dairy products, such as butter, yogurt and cheese.

The discovery, based on the identification of dairy fats on ancient pottery shards found in Libya, is the first to provide a definitive date for early dairy farming in Africa. Adding to findings from Europe and the Middle East, the study points to milk products as a main reason why people in many places may have chosen to give up the hunter-gatherer lifestyle in favor of a more settled existence.

“What we’re really beginning to know is that cattle were incredibly significant to early peoples,” said Julie Dunne, an archaeological scientist at the University of Bristol in the United Kingdom. “They gave a remarkably calorific source of food and allowed populations to expand dramatically. Milk and dairying seem to be so significant in human development, remarkably so.”

Plenty of research has documented the domestication of sheep, goats and cattle, as well as the use of dairy products, beginning around 9,000 years ago in parts of modern-day Turkey, 8,000 years ago in eastern Europe and 6,000 years ago in Britain.

In Africa, details have been murkier. Fossil evidence suggests the arrival of domesticated milk-producers in North Africa by about 8,000 years ago with an increase in animal numbers over the next 1,000 years, but remains are spotty. And even though archaeologists have discovered vivid rock art depicting cattle and even milking scenes in Algeria and other parts of the Sahara, it is impossible to accurately date those paintings.

For the new study, Dunne and colleagues analyzed organic residues on 81 well-dated pieces of pottery taken from the Takarkori rock shelter in the Libyan Sahara. The samples turned out to be incredibly well preserved, containing fat residues at high concentrations, probably because of the region’s dry conditions -- though the climate there was much wetter during the period considered in the new study.

Evidence showed that some pots were used to hold plant oils. But many contained chemical signatures that were unambiguously from animal fats, the researchers report today in the journal Nature. Analyses revealed the remains of dairy products made from cow, goat and sheep’s milk, dating back to between 7,200 and 5,800 years ago.

At that time, Africans had not yet developed the genetic mutations that allow people to digest milk, according to other research. So, the Sahara’s lactose-intolerant dairy farmers were likely making yogurt and cheese rather than drinking straight from the udders of their animals. Only after people learned to process dairy foods did their bodies develop the ability to drink pure milk -- through mutations that appear to have happened independently as many as three or four times in Africa.

It is now becoming clear that dairying was a transformative development in human history, said Joachim Burger, an evolutionary anthropologist at the University of Mainz in Germany. Given their carbohydrate and nutrient profiles, dairy products would have been far superior to what people could get from hunting and gathering alone. And when our ancestors figured that out, society changed forever.

“The general question behind all this is what actually made man to become sedentary and change his lifestyle completely,” Burger said. “Milk is not just a side effect of this change. It may even be a driving force behind it.”

An artist's reconstruction of fossils from two caves in southwest China have revealed a previously unknown Stone Age people and give a rare glimpse of a recent stage of human evolution with startling implications for the early peopling of Asia. The fossils are of a people with a highly unusual mix of archaic and modern anatomical features and are the youngest of their kind ever found in mainland East Asia. Dated to just 14,500 to 11,500 years old, these people would have shared the landscape with modern-looking people at a time when China's earliest farming cultures were beginning, says an international team of scientists led by associate professor Darren Curnoe, of the University of New South Wales, and professor Ji Xueping of the Yunnan Institute of Cultural Relics and Archeology.

Meet 'Red Deer Cave' men, possible a different species of humans discovered

'Red Deer Cave people' may be new species of human
Stone age remains of people with a penchant for home-cooked venison could represent a new human evolutionary line

The fossilised remains of stone age people recovered from two caves in south west China may belong to a new species of human that survived until around the dawn of agriculture.

The partial skulls and other bone fragments, which are from at least four individuals and are between 14,300 and 11,500 years old, have an extraordinary mix of primitive and modern anatomical features that stunned the researchers who found them.

Named the Red Deer Cave people, after their apparent penchant for home-cooked venison, they are the most recent human remains found anywhere in the world that do not closely resemble modern humans.

The individuals differ from modern humans in their jutting jaws, large molar teeth, prominent brows, thick skulls, flat faces and broad noses. Their brains were of average size by ice age standards.

"They could be a new evolutionary line or a previously unknown modern human population that arrived early from Africa and failed to contribute genetically to living east Asians," said Darren Curnoe, who led the research team at the University of New South Wales in Australia.

"While finely balanced, I think the evidence is slightly weighted towards the Red Deer Cave people representing a new evolutionary line. First, their skulls are anatomically unique. They look very different to all modern humans, whether alive today or in Africa 150,000 years ago," Curnoe told the Guardian.

"Second, the very fact they persisted until almost 11,000 years ago, when we know that very modern looking people lived at the same time immediately to the east and south, suggests they must have been isolated from them. We might infer from this isolation that they either didn't interbreed or did so in a limited way."

One partial skeleton, with much of the skull and teeth, and some rib and limb bones, was recovered from Longlin cave in Guangxi province. More than 30 bones, including at least three partial skulls, two lower jaws and some teeth, ribs and limb fragments, were unearthed at nearby Maludong, or Red Deer Cave, near the city of Mengzi in Yunnan province.

At Maludong, fossil hunters also found remnants of various mammals, all of them species still around today, except for giant red deer, the remains of which were found in abundance. "They clearly had a taste for venison, with evidence they cooked these large deer in the cave," Curnoe said.

The findings are reported in the journal PLoS ONE.

The stone age bones are particularly important because scientists have few human fossils from Asia that are well described and reliably dated, making the story of the peopling of Asia hopelessly vague. The latest findings point to a far more complex picture of human evolution than was previously thought.

"The discovery of the Red Deer Cave people shows just how complicated and interesting human evolutionary history was in Asia right at the end of the ice age. We had multiple populations living in the area, probably representing different evolutionary lines: the Red Deer Cave people on the East Asian continent, Homo floresiensis, or the 'Hobbit', on the island of Flores in Indonesia, and modern humans widely dispersed from northeast Asia to Australia. This paints an amazing picture of diversity, one we had no clue about until this last decade," Curnoe said.

Much of Asia was also occupied by Neanderthals and another group of archaic humans called the Denisovans. Scientists learned of the Denisovans after recovering a fossilised little finger from the Denisova cave in the Altai mountains of southern Siberia in 2010.

The fossils from Longlin cave were found in 1979 by a geologist prospecting in the area. At the time, researchers removed only the lower jaw and a few fragments of rib and limb bones from the cave wall. The rest of the skeleton was left encased in a block of rock, which sat in the basement of the Yunnan Institute of Cultural Relics and Archaeology in Kunming, Yunnan, for 30 years. The fossils were rediscovered in 2009 by Ji Xueping, a researcher at the institute, who teamed up with Curnoe to examine the remains.

"It was clear from what we could see that the remains were very primitive and likely to be scientifically important. We had a skilled technician remove the bones from the rock, and they were glued back together. Only then was it clear what we had found: a partial skeleton with a very unusual anatomy," Curnoe said.

The fossils at Maludong were found in 1989 but went unstudied until 2008.

Lumps of charcoal uncovered alongside the Longlin fossils were carbon dated to 11,500 years, a time when modern humans in southern China began to make pottery for food storage and to gather wild rice in some of the first steps towards full-scale farming.

Marta Mirazón Lahr, an evolutionary biologist at Cambridge University, is convinced the remains are from modern humans. The unusual features, she said, suggest the Red Deer Cave people are either "late descendants of an early population of modern humans in Asia" or a very small population that developed the traits through a process known as genetic drift.

Chris Stringer, head of human origins at the Natural History Museum, London, was similarly skeptical.

"The human remains from the Longlin Cave and Maludong are very important, particularly because we do not have much well-described and well-dated material from the late Pleistocene of China.

"The fossils are unlike recent populations of modern humans in several respects, and the mosaic of more archaic features could indicate the dispersal of a poorly known and more primitive form of modern human that left Africa before the main exodus at about 60,000 years. This dispersal could have reached as far as China, surviving there for many millennia, before disappearing in the last 12,000 years."

But he added: "There might be another possible explanation for the more archaic features. Could these alternatively be attributed to gene flow from a more archaic population that survived alongside modern humans? In the case of the Longlin Cave and Maludong fossils, the most likely candidate would be the enigmatic Denisovans who apparently interbred with the ancestors of modern Australasians somewhere in south east Asia. Could these Chinese fossils be further evidence of such hybridisation?"
