Dog family tree reveals hidden history of canine diversity

Genetic map showing how dog breeds are related provides a wealth of information about their origins.

A new family tree of dogs containing more than 160 breeds reveals the hidden history of man’s best friend, and even shows how studying canine genomes might help with research into human disease.

In a study published on 25 April in Cell Reports, scientists examined the genomes of 1,346 dogs to create one of the most diverse maps produced so far tracing the relationship between breeds¹. The map shows the types of dog that people crossed to create modern breeds and reveals that canines bred to perform similar functions, such as working and herding dogs, don't necessarily share the same origins. The analysis even hints at an ancient type of dog that could have come over to the Americas with people thousands of years before Christopher Columbus arrived in the New World.

The new work could come as a surprise to owners and breeders who are familiar with how dogs are grouped into categories. “You would think that all working dogs or all herding dogs are related, but that isn’t the case,” says Heidi Parker, a biologist at the US National Institutes of Health (NIH) in Bethesda, Maryland, and a study author.

International scientists have uncovered prehistoric human DNA of two extinct human relatives - the Neanderthals, and the Denisovans- from caves without bones, an advance that could shed new light on human history and evolution.

The technique could be valuable for reconstructing human evolutionary history, according to the study published on Thursday in the journal Science.

That's because fossilised bones, currently the main source of ancient DNA, are scarce even at sites where circumstantial evidence points to a prehistoric human presence.

"There are many caves where stone tools are found but no bones," said Matthias Meyer, a geneticist at the Max Planck Institute for Evolutionary Anthropology in Leipzig, Germany, who co-authored the study.

Listen to the experts on the Stonehenge tunnel

Helen Ghosh, Kate Mavor and Duncan Wilson’s response to John Harris’s article about the Stonehenge tunnel (Letters, 27 April) entirely misses the point. The Stonehenge world heritage site landscape is unutterably precious and you tamper with it at your peril – you cannot make it come back. There should be perpetual inquiry here and the UK government, the National Trust and English Heritage either value that or they don’t. The tunnel scheme will clearly compromise the archaeology. Whose interest would that be in? It would be better to trust the experts. The joint statement from 21 archaeological specialists working at the Stonehenge site from 14 UK universities and the international Icomos-Unesco team report recently provided detailed and empirically based rebuttals of the tunnel plans and clearly highlight various dangers it poses to the area’s archaeology and sense of place.

Iron-age Viking longhouses were burned and buried in funerals

From the Bronze Age until the Viking Age, burial mounds could be placed on top of the remains of three-aisled longhouses. The internal posts that served as roof-supporting beams were sometimes removed before the house was set on fire. Once the house had burned to the ground, one or more burial mounds were placed on top of its remains.

Marianne Hem Eriksen is a postdoc at the Department of Archaeology, Conservation and History. In an article in the European Journal of Archaeology, she investigates the causes of this practice.

'I studied seven different house burials from the Iron Age in Scandinavia, in five different locations: Högom in Sweden; Ullandhaug in Rogaland; Brista in Uppland, Sweden; Jarlsberg in Vestfold; and Engelaug in Hedmark,' Eriksen tells us.

The custom of setting houses on fire and placing burial mounds over of the house remains may be reminiscent of a cremation. Eriksen argues that the burial mounds may equally well mark the cremation and burial of a house – not necessarily a human being.

'In some cases we have been unable to find human remains, even in places where we could expect such remains to have been preserved. Nevertheless, archaeologists have more or less implicitly assumed that somewhere or other, there must be a deceased individual.'

Digital App Brings To Life One Of Scotland's Key Prehistoric Settlement Sites

A new online digital resource has been launched to bring to life one of Scotland's most important prehistoric settlement landscapes.

Led by the University of Glasgow the new digital resource aims to widen public engagement with the ongoing archaeological research in Perthshire.

Supported by a grant from Historic Environment Scotland, the SERF Project app was developed in collaboration with the 3DVisLab at the University of Dundee. It incorporates 3D images, enabling the user to grab, rotate and closely examine some of the artefacts which have been unearthed at the hillfort sites. It also features drone aerial footage of the hillforts, superimposed with artist’s reconstructions of what the sites may have looked like.

Dr Tessa Poller, Director of the SERF hillforts project and an archaeologist at the University of Glasgow, said: "This app is about wider public engagement surrounding the work we are doing, to not only show people the geographical area where these hillforts lie but to also explain how, throughout the various discoveries we have already made, we are able to challenge perceptions about what life must have been like back then.

Uffington hill carving was worshipped as 'sun horse' in prehistoric Britain

A huge prehistoric geoglyph depicting a galloping horse is traditionally thought to have been a symbol of ownership, territory or group identity for the prehistoric humans living on the Berkshire Downs. But now scholars are taking a second look at the 110-metre-long hillside carving. A new archaeological interpretation argues that it is a representation of a sun horse, a mythical beast that pulled the sun across the sky like a chariot.

The Uffington White Horse in the south of England is one of the oldest giant carved hill figures, or geoglyphs, in the world. The elongated, stylised horse is best visible from the sky, but was built millennia before a human would see it from that vantage point. It is thought to have been carved into the hillside, exposing the white chalk bedrock, in the late Second Millennium BCE or the early First Millennium BCE.

Indonesian ‘Hobbits’ Not Related To Homo Erectus

The most comprehensive study on the bones of Homo floresiensis, a species of tiny human discovered on the Indonesian island of Flores in 2003, has found that they most likely evolved from an ancestor in Africa and not from Homo erectus as has been widely believed.

The study by The Australian National University (ANU) found Homo floresiensis, dubbed "the hobbits" due to their small stature, were most likely a sister species of Homo habilis -- one of the earliest known species of human found in Africa 1.75 million years ago.

Data from the study concluded there was no evidence for the popular theory that Homo floresiensis evolved from the much larger Homo erectus, the only other early hominid known to have lived in the region with fossils discovered on the Indonesian mainland of Java.

Study leader Dr Debbie Argue of the ANU School of Archaeology & Anthropology, said the results should help put to rest a debate that has been hotly contested ever since Homo floresiensis was discovered.

Primitive human 'lived much more recently'

A primitive type of human, once thought to be up to three million years old, actually lived much more recently, a study suggests.

The remains of 15 partial skeletons belonging to the species Homo naledi were described in 2015.

They were found deep in a cave system in South Africa by a team led by Lee Berger from Wits University.

In an interview, he now says the remains are probably just 200,000 to 300,000 years old.

Why you should take your kids to Britain's smelliest attraction

Scent is the most underrated element of travel. Consider: lavender-infused Provencal fields or sulphuric water in Iceland. Each smell evokes a fundamental aspect of its place of origin. And, if you are under the age of 12, or know someone who is, consider this particular whiff: rotting flesh, with more than a hint of human excrement.

Nothing brings history alive like the scent of a turd, particularly when accompanied by a fossilised version, which you will find on display in a new case at Jorvik Viking Centre, which re-opens this weekend, 17 months after floods destroyed one of York’s most memorable attractions.

Vikings are heroes for my children’s generation thanks, in part, to How to Train Your Dragon, the historical drama Vikings and the Scandi clothing invasion, which features cheerful bearded Nordic faces on just about anything.

Divers search lake for Roman Emperor Caligula's pleasure barge, site of wild orgies

Today, the serene waters of Lake Nemi make it a quaint getaway, one that is best known for its peaceful landscapes and the area's delicious wild strawberries.

But in ancient Roman times, the volcanic lake southeast of Rome was the anchor point for Emperor Caligula's pleasure ships - massive and ornate barges that were rumored to be the sites of wild orgies and other excessive indulgences.

For nearly 2,000 years, the sunken remains of Caligula's pleasure ships tantalized divers, who launched expeditions to recover them, with little success.

It wasn't until 1927, when Italian dictator Benito Mussolini ordered Lake Nemi drained, that two of the ships began to be fully revealed. Measuring 230 and 240 feet long, the "Nemi ships" recovered over the next several years astounded researchers with their advanced technology.

A Lost Roman City Has Been Discovered in Southern France

For the first time in over a thousand years, archeologists have laid eyes on the ancient Roman town of Ucetia, which is decked out with some surprisingly well-preserved mosaics.

The discovery by the French National Institute for Preventive Archaeological Research (INRAP) was made near modern-day Uzès in the south of France during the construction of a school. The 4,000-square-meter (43,056-square-foot) site contains artifacts ranging from the Roman Republic era (1st century BCE) to the late antiquity (7th century), right through to the Middle Ages.

The town’s existence was first hinted at when researchers found an inscription saying Ucetia on a stone slab in nearby Nîmes. A few isolated fragments and mosaic pieces suggested the site of the mysterious Roman town, but it remained hidden until INRAP started to dig beneath the surface.

Prehistoric cannibalism not just driven by hunger, study reveals

Humans are less nutritious than other forms of meat, findings show, indicating complex social motivations may be behind our ancestors’ cannibalism

Evidence of cannibalism found at a number of prehistoric sites indicate our ancestors as well as other hominins such as Neanderthals sometimes ate each other.

Thursday 6 April 2017 14.00 BST Last modified on Thursday 6 April 2017 14.14 BST
Cannibalism among prehistoric humans was more likely to have been driven by social reasons than the need for a hearty meal, research suggests.

Evidence of cannibalism, in the form of cut marks, tooth marks and tell-tale bone breakage has been found at a number of prehistoric sites, including in France, Spain and Belgium, revealing that our ancestors as well as other hominins such as Neanderthals and Homo antecessor at least occasionally ate each other.
But how common cannibalism was and to what extent it was driven by the need for nutrition has been a matter of debate, with remains from some sites showing evidence of ritual treatment.

The latest study adds weight to the idea that cannibalism might have been driven by more than the necessity of hunger.

A 2,300-year-old aqueduct uncovered by workers on Rome's new Metro line has been hailed as "a sensational discovery of enormous importance" by the city's Superintendency for Archaeology.

Archaeologists first stumbled across the impressive ruin at the end of 2016, though it was not publicly announced until Sunday. On Wednesday, the team presented the results of analysis of the structure, along with that of other recent finds, at a conference hosted by Rome's Sapienza university.

Simona Morretta, who led the team of archaeologists, said the 32-metre stretch was likely part of the Aqua Appia - the oldest known Roman aqueduct, which dates back to 312 BC.

Crusader Wreck Tells Tale Of Crusader Holy Land Conquest

Christian knights and Mameluke warriors were fighting on the walls. Now the wreck of a 13th century ship reveals the desperate bid to save the Holy Land.

The port of the city of Acre was a vital lifeline for Crusader knights and settlers alike. Through it streamed European pilgrims, horses, fighting men and manufacturing goods, all vital to sustain Christianity’s tenuous hold in what would later become Palestine, Lebanon, Syria and Israel.

In return, ships carried precious cargoes of sugar, spice and exotic textiles. But, in 1291, it all came crashing down.

The Egyptian Mameluke Sultan Al-Ashraf Khalil — leading an army of 100,000 men and horses — rolled back the Christian defences, weakened by almost two centuries of fighting to maintain control over the Holy Land.

Once attached to the European mainland, a new study shows how catastrophic flooding led to Britain becoming an island about 125,000 years ago

Brexit might be causing political chaos but whatever Theresa May has up her sleeve it is unlikely to be as catastrophic as the first separation of Britain from the continent.

A new study has revealed how giant waterfalls and, later, a megaflood severed our connection to France, resulting in the creation of island Britain and the watery moat of the English Channel.

“A chance series of geological events set the stage for Britain becoming an island,” said Sanjeev Gupta, professor of earth science at Imperial College London and co-author of the research.

“If it weren’t for these events, in a sense the history of Britain would have been completely different,” he added, pointing out that if the ridge had never been breached, Britain would have remained attached to northern France with easy access to the rest of Europe.

Evidence of ancient 'geological Brexit' revealed

The UK has now started the formal process of leaving the EU, but scientists say they have evidence of a much earlier "Brexit".

They have worked out how a thin strip of land that once connected ancient Britain to Europe was destroyed.

The researchers believe a large lake overflowed 450,000 years ago, damaging the land link, then a later flood fully opened the Dover Strait.

The scars of these events can be found on the seabed of the English Channel.

The study is published in the journal Nature Communications.

Tiller the Hun? Farmers in Roman Empire converted to Hun lifestyle -- and vice versa

New archaeological analysis suggests people of Western Roman Empire switched between Hunnic nomadism and settled farming over a lifetime. Findings may be evidence of tribal encroachment that undermined Roman Empire during 5th century AD, contributing to its fall.

Marauding hordes of barbarian Huns, under their ferocious leader Attila, are often credited with triggering the fall of one of history's greatest empires: Rome.

Historians believe Hunnic incursions into Roman provinces bordering the Danube during the 5th century AD opened the floodgates for nomadic tribes to encroach on the empire. This caused a destabilisation that contributed to collapse of Roman power in the West.


According to Roman accounts, the Huns brought only terror and destruction. However, research from the University of Cambridge on gravesite remains in the Roman frontier region of Pannonia (now Hungary) has revealed for the first time how ordinary people may have dealt with the arrival of the Huns.

Rare ‘Coffin Birth' Found At Black Death Burial Site In Northern Italy

Researchers investigating a 14th century burial ground have identified a rare case of "coffin birth" - a gruesome phenomenon in which a deceased pregnant woman's fetus is expelled within the grave.

The event, which has seldom been reported in archaeology, is known as postmortem fetal extrusion. It results from a build-up of gas pressure within the decomposing body.

"In this case, we have a partial expulsion of a 38- to 40-week-old fetus, which was found to be complete and to lie within the birth canal," Deneb Cesana, at the University of Genova, told Seeker.

The remains of the woman and her unborn baby were originally uncovered in 2006, interred with two other young individuals that scientists say were aged 12 and three years old. Only recently has the discovery been fully investigated.

Archeologists digging at a site in Tiel in the province of Gelderland, have found a rich haul of Roman artefacts, among which a statue of the god Jupiter, a grave stone inscribed DEAE (to the goddess), 2,500 bronze objects and a unique ointment pot. 

The dig is one of a number of archaeological activities taking place on an 80 hectare site which is projected to become part of the adjacent Medel industrial estate. As with any major construction work, archaeologists are invited to investigate what is in the ground before any building is done. 

The area has yielded treasure before. In November last year archaeologists found numerous artefacts dating back some 6,000 years, and a Roman funerary urn with a small glass bottle inside it.

A decorated raven bone discovered in Crimea may provide insight into Neanderthal cognition

The cognitive abilities of Neanderthals are debated, but a raven bone fragment found at the Zaskalnaya VI (ZSK) site in Crimea features two notches that may have been made by Neanderthals intentionally to display a visually consistent pattern, according to a study by Ana Majkic at the Universite de Bordeaux and colleagues, published in the open access journal, PLOS ONE on March 29, 2017.

Majkic and colleagues conducted a mixed-methods study to assess whether the two extra notches on the ZSK raven bone were made by Neanderthals with the intention of making the final series of notches appear to be evenly spaced. First, researchers conducted a multi-phase experiment where recruited volunteers were asked to create evenly spaced notches in domestic turkey bones, which are similar in size to the ZSK raven bone. Morphometric analyses reveal that the equal spacing of the experimental notches was comparable to the spacing of notches in the ZSK raven bone, even when adjusted for errors in human perception. Archeological specimens featuring aligned notches from different sites were also analyzed and compared with the ZSK raven bone specimen.

Iron Age chariot and horse found buried together in Yorkshire

The two Iron Age horses, once used to pull the chariot are examined on site by archaeologists

The Ancient Brits loved their wheels. Indeed they seem to have been so attached to their sports-car-style chariots that they may even have thought they could use them to get to the next world.

Academic knowledge about these elegant high status prehistoric British vehicles is now set to increase significantly, following the discovery of an ancient Briton buried inside his chariot in East Yorkshire.

Although around 20 other similar chariot graves have been found over the past century or so in the UK (mainly in Yorkshire), this new discovery, unearthed on the outskirts of the market town of Pocklington at the foot of the Yorkshire Wolds, is the only example ever excavated by modern archaeologists in which the two horses, used to pull the vehicle, were also interred.

Crete’s Late Minoan Tombs Point Way To Early European Migration

Researchers at the University of Huddersfield have visited Rethymnon in Crete, to collect samples from the late Bronze Age Necropolis of Armenoi, one of the world's finest archaeological sites. DNA analysis of the ancient skeletal remains could provide fresh insights into the origins of European civilisation.

Dr Ceiridwen Edwards and PhD student George Foody were permitted to take bone samples and teeth from over 110 of the more than 600 skeletons discovered in the Necropolis, a rock-hewn burial site from the Late Minoan period dating to more than 4,000 years ago. During their two-week visit, the Huddersfield researchers – part of a team that included colleagues from Oxford University and the Hellenic Archaeological Research Foundation – also took DNA swabs from more than 100 contemporary Cretans. They sought people whose grandmothers were from Crete in order to analyse links to the Minoan period.

When the ancient DNA samples are compared with those of modern Cretans, there is the potential to find solutions to many issues surrounding the ancient migration of people and culture to an island where the Bronze Age Minoans and their successors the Mycenaeans laid foundations for later European civilisation and culture.

Medieval villagers mutilated the dead to stop them rising, study finds

A study by archaeologists has revealed certain people in medieval Yorkshire were so afraid of the dead they chopped, smashed and burned their skeletons to make sure they stayed in their graves.

The research published by Historic England and the University of Southampton may represent the first scientific evidence in England of attempts to prevent the dead from walking and harming the living – still common in folklore in many parts of the world.

The archaeologists who studied a collection of human bones – including the remains of adults, teenagers and children excavated more than half a century ago, and dated back to the period between the 11th and 14th century – rejected gruesome possibilities including cannibalism in times of famine, or the massacre of outsiders. The cut marks were in the wrong place for butchery, and isotope analysis of the teeth showed that the people came from the same area as the villagers of Wharram Percy in North Yorkshire – a once flourishing village which had been completely deserted by the early 16th century.
