The Scotsman reports some surprising results from recent Scottish DNA research.

ScotlandsDNA, the groundbreaking research project that probes far beyond the ink stains of family trees by analysing the genetic make-up of Scottish men and women, has unveiled its interim results, which show that 1 per cent of all Scots are descended from the Berber and Tuareg tribesmen of the Sahara.

My own patrilineal DNA results (Excel file) are very similar to the DNA of Somerled, the 12th century Lord of the Isles, from whom descend the various septs of Clan Donald.

It has become possible recently to identify Napoleon’s dna from samples taken from male descendants of his brothers. Napoleon’s dna is unusual and distinctive, and—interestingly—turns out to be an example of Haplogroup E1b1b1c1, a group of Levantine origin, which suggest that Napoleon Bonaparte’s ultimate male descent was from ancient Phoenecian traders, or Sephardic Jews, or possibly even from the Moors, which did not keep him having blond hair as young man (which later darkened) and grey-blue eyes.

If your Y-dna is from Haplogroup E1b1b1c1, you will want to drop by the Napoleon DNA Project to compare your own results.

The discovery of a new mitochondrial DNA (mtDNA) subclade (C1e) in Iceland of Haplogroup C, characteristic of population groups found in Northeast Asia and of Amerindians is identified in a new paper in the American Journal of Physical Anthropology as likely evidence of the presence in Iceland of matrilineal descent from American Indians encountered by Viking explorers of North America around the year 1000 A.D.

Abstract

Although most mtDNA lineages observed in contemporary Icelanders can be traced to neighboring populations in the British Isles and Scandinavia, one may have a more distant origin. This lineage belongs to haplogroup C1, one of a handful that was involved in the settlement of the Americas around 14,000 years ago. Contrary to an initial assumption that this lineage was a recent arrival, preliminary genealogical analyses revealed that the C1 lineage was present in the Icelandic mtDNA pool at least 300 years ago. This raised the intriguing possibility that the Icelandic C1 lineage could be traced to Viking voyages to the Americas that commenced in the 10th century. In an attempt to shed further light on the entry date of the C1 lineage into the Icelandic mtDNA pool and its geographical origin, we used the deCODE Genetics genealogical database to identify additional matrilineal ancestors that carry the C1 lineage and then sequenced the complete mtDNA genome of 11 contemporary C1 carriers from four different matrilines. Our results indicate a latest possible arrival date in Iceland of just prior to 1700 and a likely arrival date centuries earlier. Most surprisingly, we demonstrate that the Icelandic C1 lineage does not belong to any of the four known Native American (C1b, C1c, and C1d) or Asian (C1a) subclades of haplogroup C1. Rather, it is presently the only known member of a new subclade, C1e. While a Native American origin seems most likely for C1e, an Asian or European origin cannot be ruled out.

The last confirmed (until now) mountain lion resident in the Northeastern United States was killed by a trapper in Somerset County, Maine in 1938.

Mountain lions are thought by the wildlife experts to have a habitat range of 50 to 350 square miles.

DNA tests demonstrate that a mountain lion which was struck and killed by a 2006 Hyundai Tucson SUV around 1:00 a.m. on June 11 on Wilbur Cross Parkway in the area of Exit 55 in Milford, Connecticut came from far away and seems to have set something of a record for mountain lion roaming.

Middletown (CT) Press:

The Connecticut Department of Energy and Environmental Protection said today that results of genetic tests show that the mountain lion killed in Milford in June made its way to the state from the Black Hills region of South Dakota and is an animal whose movements were actually tracked and recorded as it made its way through Minnesota and Wisconsin.

Genetic tests also show that it is likely that the mountain lion killed when it was hit by a car June 11 on the Wilbur Cross Parkway in Milford was the same one that had been seen earlier that month in Greenwich.

Science quotes, from a lecture given at the 7th World Congress on Mummy Studies, the latest findings concerning Europe’s oldest natural human mummy, found in September 1991 in the Ötztal Alps, near Hauslabjoch on the border between Austria and Italy and usually referred to as Ötzi or the Iceman.

Less than 2 hours before he hiked his last steps in the Tyrolean Alps 5000 years ago, Ötzi the Iceman fueled up on a last meal of ibex meat. That was the conclusion of a talk here last week at the 7th World Congress on Mummy Studies, during which researchers—armed with Ötzi’s newly sequenced genome and a detailed dental analysis—also concluded that the Iceman had brown eyes and probably wasn’t much of a tooth brusher.

The Iceman, discovered in the Italian Alps in 1991 some 5200 years after his death, has been a gold mine of information about Neolithic life, as researchers have extensively studied his gear—copper ax, hide and leather clothing, and accessories—and his body. Previous research on the Iceman’s meals focused on fecal material removed from his bowels. The contents showed that he dined on red deer meat and possibly cereal some 4 hours before his death.

But a team led by microbiologist Frank Maixner of the Institute for Mummies and the Iceman in Bolzano, Italy, recently reexamined computed tomography scans taken in 2005 and spotted, for the first time, the Iceman’s stomach. As the researchers reported at the meeting, the organ had moved upward to an unusual position, and it looked full. When they took a sample of the stomach contents and sequenced the DNA of the animal fibers they found, they discovered that Ötzi, just 30 to 120 minutes before his death, had dined on the meat of an Alpine ibex, an animal that frequents high elevations and whose body parts were once thought to possess medicinal qualities.

The new findings are “cutting edge” says Niels Lynnerup, a specialist in forensic medicine at the University of Copenhagen. “We are now inching our way to the last minutes of the Iceman.”

In a separate presentation, dentist Roger Seiler and anatomist Frank Rühli of the Centre for Evolutionary Medicine at the University of Zürich, examined the dental health of the Iceman, who probably died between the age of 35 and 40. Previously, researchers examining radiological images of his teeth discerned no trace of cavities or other dental problems. But the Swiss team created new three-dimensional images of the ancient traveler’s dentition. These showed that the Iceman suffered a blunt force trauma to two teeth—possibly a blow to the mouth—at least several days before his death and was plagued by both periodontal disease and cavities. The cavities, Seiler said in his talk, confirm that the Iceman ate a diet abounding in carbohydrates, such as bread or cereal, and reveal that he possessed a “heavy bacterial dose on these teeth.”

Newspaper reports are sketchy. They never mention the specifics of the testing or identify the alleged results, and they do not offer a mention of the names of the scientists doing the testing or refer to any papers. They just tell the story.

Telegraph:

Genetic testing of villagers in a remote part of China has shown that nearly two thirds of their DNA is of Caucasian origin, lending support to the theory that they may be descended from a “lost legion” of Roman soldiers.

Tests found that the DNA of some villagers in Liqian, on the fringes of the Gobi Desert in north-western China, was 56 per cent Caucasian in origin. Many of the villagers have blue or green eyes, long noses and even fair hair, prompting speculation that they have European blood.

A local man, Cai Junnian, is nicknamed Cai Luoma, or “Cai the Roman”, and is one of many villagers convinced that he is descended from the lost legion.

————————————-

English.news.cn:

Chinese and Italian anthropologists this week established an Italian studies center at a leading university in northwest China to determine whether some Western-looking Chinese in the area are the descendants of a lost Roman army of ancient times.

Experts at the Italian Studies Center at Lanzhou University in Gansu Province will conduct excavations on a section of the Silk Road, a 7,000-km-long trade route that linked Asia and Europe more than 2,000 years ago, to see if it can be proved a legion of lost Roman soldiers settled in China, said Prof. Yuan Honggeng, head of the center.

“We hope to prove the legend by digging and discovering more evidence of China’s early contact with the Roman Empire,” said Yuan.

Before Marco Polo’s travels to China in the 13th century, the only known contact between the two empires was a visit by Roman diplomats in 166 A.D.

Chinese archeologists were therefore surprised in the 1990s to find the remains of an ancient fortification in Liqian, a remote town in Yongchang County on the edge of the Gobi desert, which was strikingly similar to Roman defence structures.

They were even more astonished to find western-looking people with green, deep-set eyes, long and hooked noses and blonde hair in the area.

Though the villagers said they had never traveled outside the county, they worshipped bulls and their favorite game was similar to the ancient Romans’ bull-fighting dance.

DNA tests in 2005 confirmed some of the villagers were indeed of foreign origin, leading many experts to conclude they are the descendants of the ancient Roman army headed by general Marcus Crassus.

In 53 B.C., Crassus was defeated and beheaded by the Parthians, a tribe occupying what is now Iran, putting an end to Rome’s eastward expansion.

But a 6,000-strong army led by Crassus’s eldest son apparently escaped and were never found again.

————————————-

And here we see why. The science actually debunked the legend, but the press published the legend and misreported the DNA test results.

An article in the Journal of Human Genetics 52 (7): 584–91, titled: Testing the hypothesis of an ancient Roman soldier origin of the Liqian people in northwest China: a Y-chromosome perspective. seems to explain that DNA testing proved the exact opposite of the accounts in the newspapers.

ABSTRACT:

The Liqian people in north China are well known because of the controversial hypothesis of an ancient Roman mercenary origin. To test this hypothesis, 227 male individuals representing four Chinese populations were analyzed at 12 short tandem repeat (STR) loci and 12 single nucleotide polymorphisms (SNP). At the haplogroup levels, 77% Liqian Y chromosomes were restricted to East Asia. Principal component (PC) and multidimensional scaling (MDS) analysis suggests that the Liqians are closely related to Chinese populations, especially Han Chinese populations, whereas they greatly deviate from Central Asian and Western Eurasian populations. Further phylogenetic and admixture analysis confirmed that the Han Chinese contributed greatly to the Liqian gene pool. The Liqian and the Yugur people, regarded as kindred populations with common origins, present an underlying genetic difference in a median-joining network. Overall, a Roman mercenary origin could not be accepted as true according to paternal genetic variation, and the current Liqian population is more likely to be a subgroup of the Chinese majority Han.

This example illustrates why it is inadvisable to base one’s views on Anthropogenic Global Warming or the existence of Bigfoot on newspaper accounts.

A new paper in Forensic Science International: Genetics by Carles Lalueza-Fox, Elena Gigli, Carla Bini, Francesc Calafella, Donata Luiselli, Susi Pelotti, and Davide Pettener details the results of DNA analysis of the unfortunate King Louis XVI of France executed by the Revolutionary convention 21 January 1793.

Wikipedia notes: “It is agreed that while Louis’s blood dripped to the ground many members of the crowd ran forward to dip their handkerchiefs in it.”

Abstract:

A text on a pyrographically decorated gourd dated to 1793 explains that it contains a handkerchief dipped with the blood of Louis XVI, king of France, after his execution. Biochemical analyses confirmed that the material contained within the gourd was blood. The mitochondrial DNA (mtDNA) hypervariable region 1 (HVR1) and 2 (HVR2), the Y-chromosome STR profile, some autosomal STR markers and a SNP in HERC2 gene associated to blue eyes, were retrieved, and some results independently replicated in two different laboratories. The uncommon mtDNA sequence retrieved can be attributed to a N1b haplotype, while the novel Y-chromosome haplotype belongs to haplogroup G2a. The HERC2 gene showed that the subject analyzed was a heterozygote, which is compatible with a blue-eyed person, as king Louis XVI was. To confirm the identity of the subject, an analysis of the dried heart of his son, Louis XVII, could be undertaken.

The mitochondrial dna haplogroup N1b is a decidedly unusual. Louis XVI’s mother was Princess Maria Josepha of Saxony, the daughter of Maria Josepha of Austria, granddaughter of Wilhelmine Amalia of Brunswick-Lüneburg, ggd of Benedicta Henrietta of the Palatinate, gggd of Anne Gonzaga, ggggd of Catherine of Mayenne, a member of the House of Guise, a junior branch of the royal House of Lorraine.

What little discussion of haplogroup N1b ( named for imaginary female ancestress “Nana” by “Seven Daughter of Eve” author Bryan Sykes) exists on the Internet is here.

His patrilineal Ydna haplogroup G2 is also Pan-Eurasian and also rather unusual. The kings of France ultimately descend in the male line from Robert the Strong.

The old Allied canard that Hitler was really Jewish may actually be true. The Telegraph report is vague and is clearly written by someone who does not really understand genealogical DNA testing or Y-chromosome Haplogroups.

Human gender is genetically determined by two chromosomes, X and Y. A pair of X chromosomes results in a female. X and Y produces a male.

Patrilineal descent can be determined by the specific markers inherited in male Y chromosomal dna. Haplogroups of typical Ydna markers have been identified, of which a little more than a dozen are characteristically found in European populations.

Saliva samples taken from 39 relatives of the Nazi leader show he may have had biological links to the “subhuman” races that he tried to exterminate during the Holocaust.

Jean-Paul Mulders, a Belgian journalist, and Marc Vermeeren, a historian, tracked down the Fuhrer’s relatives, including an Austrian farmer who was his cousin, earlier this year.

A chromosome called Haplogroup E1b1b1 which showed up in their samples is rare in Western Europe and is most commonly found in the Berbers of Morocco, Algeria and Tunisia, as well as among Ashkenazi and Sephardic Jews.

“One can from this postulate that Hitler was related to people whom he despised,” Mr Mulders wrote in the Belgian magazine, Knack.

Haplogroup E1b1b1, which accounts for approximately 18 to 20 per cent of Ashkenazi and 8.6 per cent to 30 per cent of Sephardic Y-chromosomes, appears to be one of the major founding lineages of the Jewish population. ...

“The affair is fascinating if one compares it with the conception of the world of the Nazis, in which race and blood was central.

“Hitler’s concern over his descent was not unjustified. He was apparently not “pure” or ‘Ayran’.”

It is not the first time that historians have suggested Hitler had Jewish ancestry.

His father, Alois, is thought to have been the illegitimate offspring of a maid called Maria Schickelgruber and a 19-year-old Jewish man called Frankenberger.

If the Belgian magazine really tested the Ydna of persons sharing patrilineal descent with Adolph Hitler and found the haplogroup he shared to have been E1b1b1, that means his paternal descent was typically Levantine and he probably really was of Jewish descent in the male line.

There were racial laws during the time he was alive in Germany that could have produced big problems for him.

A New Zealand representative of the Percy family is attempting to claim the earldom and estates of the ancient Percy family of Northumberland on the basis of a supposititious descent from a male-line overlooked at the time of the death of Josceline the 7th Earl in 1670.

No male heir was discovered at that time, and the Percy estates went to his only daughter, Lady Elizabeth, who married three times, becoming by her last marriage Duchess of Somerset.

Her granddaughter, also an Elizabeth, married Sir Hugh Smithson in 1740, causing him to inherit the Earldom of Northumberland upon her father’s death. Smithson obligingly changed his name to Percy, and received the extinct title of Duke of Northumberland via a third creation in 1766.

Kevin Percy of Napier, New Zealand believes that the commonality of the personal name Thomas, Edward, and Francis between his own (formerly) Pursey family and that of Thomas Percy, great grandson of the 4th earl of Northumberland and one of the principals of the Gunpowder Plot suggests the identity of his own ancestry with one of the cadet lines of the famous Percys of Northumberland.

All of this is explained at a web-page devoted to the Percy family of New Zealand and its genealogical theories.

Mr. Percy hopes that DNA testing of exhumed Percy bodies will be able to prove his own descent from the Gunpowder Plotter and confirm his own theories making him rightful heir to the Percy family titles and estates.

As the Dominion Post (Wellington, N.Z.) reports, were he to be successful, the rewards would be awfully good.

A Napier antiques dealer has claimed that his family are the rightful heirs to one of Britain’s most famous dynasties, which owns the castle used in the Harry Potter movies.

Kevin Percy, 74, believes his family was cheated out of inheriting the Earl of Northumberland’s massive estate, now conservatively valued at $685m.

He has started a bold bid asking British authorities, including the Queen, to exhume the bodies of two suspected relatives for DNA tests, which he says would prove or disprove his claim. The two men died in 1560 and 1716.

His bid targets one of Britain’s most celebrated noble families, which dominated the Middle Ages. The earldom owns nearly 50,000 hectares of land in Britain.

Are you a genetically a dandelion or an orchid? Both have their place in the evolutionary scheme of things according to a recent article in the Atlantic by David Dobbs.

Most of us have genes that make us as hardy as dandelions: able to take root and survive almost anywhere. A few of us, however, are more like the orchid: fragile and fickle, but capable of blooming spectacularly if given greenhouse care. So holds a provocative new theory of genetics, which asserts that the very genes that give us the most trouble as a species, causing behaviors that are self-destructive and antisocial, also underlie humankind’s phenomenal adaptability and evolutionary success. With a bad environment and poor parenting, orchid children can end up depressed, drug-addicted, or in jail—but with the right environment and good parenting, they can grow up to be society’s most creative, successful, and happy people.

Jonathan Shaw in Harvard Magazine explains that studies of population DNA suggest that an effective policy of sexual apartheid practiced by the newly arrived Anglo-Saxons could have eliminated British male Y chromosomal DNA in as few as five generations. The Spanish conquistadores in Colombia and the Vikings in Scotland and Ireland left similar DNA patterns, in which the male heredity of the modern population is overwhelming traceable to the invaders, but female mitochondrial DNA predominantly descends from the conquered population.

Moral? Successful invaders get the girls. At some level, history amounts to a contest over who gets to reproduce his DNA, and who does not.

There are no signs of a massacre—no mass graves, no piles of bones. Yet more than a million men vanished without a trace. They left no descendants. Historians know that something dramatic happened in England just as the Roman empire was collapsing. When the Anglo-Saxons first arrived in that northern outpost in the fourth century a.d.—whether as immigrants or invaders is debated—they encountered an existing Romano-Celtic population estimated at between 2 million and 3.7 million people. Latin and Celtic were the dominant languages. Yet the ensuing cultural transformation was so complete, says Goelet professor of medieval history Michael McCormick, that by the eighth century, English civilization considered itself completely Anglo-Saxon, spoke only Anglo-Saxon, and thought that everyone had “come over on the Mayflower, as it were.” This extraordinary change has had ramifications down to the present, and is why so many people speak English rather than Latin or Celtic today. But how English culture was completely remade, the historical record does not say.

Then, in 2002, scientists found a genetic signature in the DNA of living British men that hinted at an untold story of Anglo-Saxon conquest. The researchers were sampling Y-chromosomes, the sex chromosome passed down only in males, from men living in market towns named in the Domesday Book of 1086. Working along an east-west transect through central England and Wales, the scientists discovered that the mix of Y-chromosomes characteristic of men in the English towns was very different from that of men in the Welsh towns: Wales was the primary Celtic holdout in Western Britannia during the ascendance of the Anglo-Saxons. Using computer analysis, the researchers explored how such a pattern could have arisen and concluded that a massive replacement of the native fourth-century male Britons had taken place. Between 50 percent and 100 percent of indigenous English men today, the researchers estimate, are descended from Anglo-Saxons who arrived on England’s eastern coast 16 centuries ago. So what happened?

Science Daily:

Scientists at the Centre for Addiction and Mental Health (CAMH) have detected evidence that DNA may not be the only carrier of heritable information; a secondary molecular mechanism called epigenetics may also account for some inherited traits and diseases. These findings challenge the fundamental principles of genetics and inheritance, and potentially provide a new insight into the primary causes of human diseases.

Everyone with blue eyes shares a common matrilineal ancestor who lived between 6000 and 10000 years ago.

The New York Times summarizes an article on European Genetics from Current Biology which arrives the conclusion that it could very likely be possible to identify the nationality of Europeans by genetic testing.

Europe has been colonized three times in the distant past, always from the south. Some 45,000 years ago the first modern humans entered Europe from the south. The glaciers returned around 20,000 years ago and the second colonization occurred about 17,000 years ago by people returning from southern refuges. The third invasion was that of farmers bringing the new agricultural technology from the Near East around 10,000 years ago.

The pattern of genetic differences among present day Europeans probably reflects the impact of these three ancient migrations, Dr. Kayser said.

The map also identifies the existence of two genetic barriers within Europe. One is between the Finns (light blue, upper right) and other Europeans. It arose because the Finnish population was at one time very small and then expanded, bearing the atypical genetics of its few founders.

The other is between Italians (yellow, bottom center) and the rest. This may reflect the role of the Alps in impeding free flow of people between Italy and the rest of Europe.

Results show modern humans, Neandertals diverged 660,000 years ago

An international consortium of researchers reports in the Aug. 8 Cell that for the first time the complete sequence of mitochondrial DNA from a Neandertal has been deciphered. Comparison of the Neandertal sequence with mitochondrial sequences from modern humans confirms that the two groups belong to different branches of humankind’s family tree, diverging 660,000 years ago.

That date is not statistically different from previous estimates of the split between humans and Neandertals, says Erik Trinkaus, a paleoanthropologist at Washington University in St. Louis. The sequence also doesn’t reveal what happened to drive Neandertals to extinction, but it does clear up some discrepancies in earlier studies. ...

At 16,565 bases long, the new sequence is the largest stretch of Neandertal DNA ever examined. The DNA was isolated from a 38,000-year-old bone found in a cave in Croatia.

“It’s a nice accomplishment and the next important step toward completing the Neandertal genome,” says Stephan Schuster of Pennsylvania State University in University Park. Schuster is part of a group that is sequencing the genomes of the mammoth and other extinct animals, but was not involved in the current study. “It’s a nice landmark on the way to saying what makes modern humans so special.”

In order to know exactly how modern humans and Neandertals differ, scientists will need to examine DNA from the Neandertal’s entire genome. The sequence reported in the new study was generated as part of a project to decode Neandertal DNA, but it contains information only about DNA from mitochondria.

Mitochondria are organelles that generate energy for a cell. Inside each mitochondrion is a circular piece of DNA that contains genes encoding some of the key proteins responsible for power generation. Mitochondria are passed down from mothers to their children. Scientists use variations in mitochondrial DNA as a molecular clock to tell how fast species are evolving.

Scientists have previously examined a short piece of Neandertal mitochondrial DNA known as the hypervariable region, but this new complete sequence helps clear up some ambiguities from studies comparing Neandertals and humans, says John Hawks, a biological anthropologist from the University of Wisconsin–Madison.

Some modern humans have several changes in the hypervariable region that made it seem as if Neandertals are more closely related to modern humans than humans are to each other.

“Comparing the complete mitochondrial DNA genomes of a Neandertal and many recent humans presents a very different picture,” Hawks says. “Humans are all more similar to each other, than any human is to a Neandertal. And in fact the Neandertal sequence is three or more times as different, on average, from us as we are from each other. This change from the earlier picture is a purely statistical one, but it makes a clearer picture.”

Human and Neandertal mitochondrial DNAs differ at 206 positions out of the 16,565 examined, while modern humans differ at only about 100 positions when compared with each other.

British newspapers report that living residents of Nienstedt, a village in the foothills of the Harz Mountains in Lower Saxony, have been found by DNA analysis to be relatives of 3000-year-old Bronze Age inhabitants of the same area interred in the nearby Lichtensteinhöhle cave.

———————————————————————————————-

London Times:

The good news for two villagers in the Söse valley of Germany yesterday was that they have discovered their (127th times)-great grandparents.

The bad news is that their long-lost ancestors may have grilled and eaten other members of their clan.

Every family has its skeletons in the cave, though, so Manfred Hucht-hausen, 58, a teacher, and 48-year-old surveyor Uwe Lange remained in celebratory mood. Thanks to DNA testing of remarkably well-preserved Bronze Age bones, they can claim to have the longest proven family tree in the world. “I can trace my family back by name to 1550,” Mr Lange said. “Now I can go back 120 generations.”

Mr Lange comes from the village of Nienstedt, in Lower Saxony, in the foothills of the Harz mountain range. “We used to play in these caves as kids. If I’d known that there were 3,000-year-old relatives buried there I wouldn’t have set foot in the place.”

The cave, the Lichtensteinhöhle, is made up of five interlocked natural chambers. It stayed hidden from view until 1980 and was not researched properly until 1993. The archaeologist Stefan Flindt found 40 skeletons along with what appeared to be cult objects. ...

Analysis showed that all the bones were from the same family and the scientists speculated that it was a living area and a ceremonial burial place.

About 300 locals agreed to giving saliva swabs. Two of the cave family had a very rare genetic pattern – and a match was found.

Telegraph:

The bones of 40 people were shielded from the elements by calcium deposits that formed a protective skin around the skeletons.

All the remains turned out to be from the same family group who had a distinctive – and rare – DNA pattern.

When people in the local area were tested with saliva swabs, two nearby residents turned out to have the same distinctive genetic characteristic.

Manfred Huchthausen, a 58-year-old teacher, and Uwe Lange, a 48-year-old surveyer, now believe they are even more local than either of them thought.

DNA analysis really found that 15 of 22 skeletons were relatives, constituting several generations of a family clan. In 2007, about 300 DNA samples of today’s indigenous population in Osterode-am-Harz were collected and tested for possible affinity. Susann Hummel, a leading anthropologist, has identified eleven living persons as descendants of the cave burials.

Ten lines of mtDNA haplogroup H, four of haplogroup U, two of the haplogroup J and three of the haplogroup T were identified. A further breakdown in the sub-groups succeeded in identifying U5b, T2 and J1b1. In another case, membership in sub-group U2 was considered very likely.

Human beings may have had a brush with extinction 70,000 years ago, an extensive genetic study suggests. The human population at that time was reduced to small isolated groups in Africa, apparently because of drought, according to an analysis released Thursday.

The report notes that a separate study by researchers at Stanford University estimated the number of early humans may have shrunk as low as 2,000 before numbers began to expand again in the early Stone Age.

“This study illustrates the extraordinary power of genetics to reveal insights into some of the key events in our species’ history,” Spencer Wells, National Geographic Society explorer in residence, said in a statement. “Tiny bands of early humans, forced apart by harsh environmental conditions, coming back from the brink to reunite and populate the world. Truly an epic drama, written in our DNA.”

Wells is director of the Genographic Project, launched in 2005 to study anthropology using genetics. The report was published in the American Journal of Human Genetics.

Previous studies using mitochondrial DNA — which is passed down through mothers — have traced modern humans to a single “mitochondrial Eve,” who lived in Africa about 200,000 years ago.

The migrations of humans out of Africa to populate the rest of the world appear to have begun about 60,000 years ago, but little has been known about humans between Eve and that dispersal.

The new study looks at the mitochondrial DNA of the Khoi and San people in South Africa which appear to have diverged from other people between 90,000 and 150,000 years ago.

The BBC reports the study’s conclusion that mankind nearly split into two separate species at the same time.

Ancient humans started down the path of evolving into two separate species before merging back into a single population, a genetic study suggests.

The genetic split in Africa resulted in distinct populations that lived in isolation for as much as 100,000 years, the scientists say.

This could have been caused by arid conditions driving a wedge between humans in eastern and southern Africa.

Genetic studies apparently have found a mutation which took place 6-10,000 years ago and is the cause of the eye color of all blue-eyed humans alive on the planet today.

But aren’t the divergences of the predominant European Ydna and mtDNA haplogroups a good deal older than that?

The region around Liverpool was once a major Viking settlement, according to a genetic study of men living in the area.

The research tapped into this Viking ancestry by focusing on people whose surnames were recorded in the area before its population underwent a huge expansion during the industrial revolution. Among men with these “original” surnames, 50% have Norse ancestry.

The find backs up historical evidence from place names and archaeological finds of Viking treasure which suggests significant numbers of Norwegian Vikings settled in the north-west in the 10th century. “[The genetics] is very exciting because it ties in with the other evidence from the area,” said Professor Stephen Harding at the University of Nottingham, who carried out the work with a team at the University of Leicester led by Professor Mark Jobling.

They used historical documents, including a tax register from the time of Henry VIII, to identify surnames common in the region. They then recruited 77 male volunteers with “original” surnames, and looked for a genetic signature of Viking ancestry on the Y chromosome. They report in Molecular Biology and Evolution that a Y chromosome type, R1a, common in Norway, is also very common among men with original surnames.

BBC:

US scientists say an animal found in Texas is not the chupacabra – or goat-sucker – of American myth, but a coyote with a hair loss problem.
DNA tests on the carcass found at a ranch south-east of San Antonio yielded a virtually identical match to coyote DNA, biologist Mike Forstner said.

The coyote was one of three found dead by rancher Phylis Canion this summer.

Central American myth has long spoken of a vampire-like creature that slays livestock by sucking out their blood.

The chupacabra is said to attack its victims at night, leaving a trail of carcasses with their throats torn out.

Mr Forstner said that he himself had assumed the creature brought in for testing at Texas State University was a domestic dog but “the DNA sequence is a virtually identical match to DNA from the coyote”.

Ms Canion and some of her neighbours discovered the 40-pound (18-kg) carcasses of three of the animals over four days in July outside her ranch in Cuero, 90 miles (145km) south-east of San Antonio.

She said she had saved the head of one of them to get it properly tested.

Additional hide samples have been taken to try to determine the cause of the animal’s hair loss, Mr Forstner said.

A yearlong investigation into the genetic makeup of the large animal, initially mistaken for a coyote, found “a substantial amount of wolf ancestry,” according to John Austin of the Vermont Fish and Wildlife Department.

“We’re trying to be cautious in how we interpret these results,” Austin said Tuesday. “What the information tells us is that the genetic composition, the size of animal … suggests it’s largely of wolf ancestry.”

The animal, shot by a farmer in a Vermont town along the Canadian border Oct. 1, 2006, could well have been a wolf. But scientists say it likely wasn’t wild. Genetic tests conducted at four laboratories, including the U.S. Fish and Wildlife Service’s forensics laboratory in Ashland, Ore., traced the ancestry of the animal to two separate and geographically distinct populations of wolves. The animal, according to lab conclusions, was almost certainly bred in captivity.

Peggy Struhsacker, a wolf specialist for the Natural Resources Defense Council, examined the animal after it was shot last October and said Tuesday that laboratory testing supported her initial hunches.

“I looked at all the traits and characteristics of it and believed it was possibly a full wolf or a high-percentage animal because it had all physical characteristics,” Struhsacker said. “That being said, it had too many other characteristics that made me feel it wasn’t a wild wolf.”

The animal’s shoddy coat, uniform nail wear and well-fed gut, she said, all indicated the canine was a domestic pet.

The animal’s origins have significant implications for the state. If the animal was indeed a wild wolf migrating from an existing pack in southern Quebec, it would signal the reappearance of an animal extirpated from the state in the 1800s.

“We’re really interested in trying to determine the origin of large canids when they turn up in New England,” said Kim Royar, a wildlife biologist with the Vermont Fish & Wildlife Department. “If it turns out, like the lab suggested, that this animal is of domestic origin, then basically we would assume it had been released into the wild by somebody who had bred it for sale. What we’re interested in is documenting whether there is movement of wolves from wild populations … in eastern Canada down to New England.”

Royar said the state has no evidence that such movement has occurred, though reports of wild wolves in Maine and New Hampshire suggest wolf populations may be crossing into the northeastern United States.

Michael Amaral, endangered species specialist for the U.S. Fish and Wildlife Service, said the discovery should signal a warning to hunters in the state. The wolf is protected by the federal Endangered Species Act and hunters who shoot them, mistakenly or intentionally, he said, face stiff fines.

“Gray wolves, even if they are of captive origin, are a protected species,” Amaral said. “I think the important message for Vermont’s hunters is it’s not beyond the realm of possibility that wolves can get to northern Vermont from existing wolf populations in Canada.”

Charlie Hammond, the man who shot the wolf in Troy, won’t be prosecuted, according to Amaral.

“Because it appears that this animal was of domestic origin … and other circumstances, we are not prosecuting in this case,” Amaral said.

Steve Mcleod is executive director of the Vermont Traditions Coalition, an organization that lobbies on behalf of hunters, farmers and other groups opposed to the reintroduction of the gray wolf to Vermont. He said a resurgence of the animal in the state would signal the decline of deer populations.

“There would be a deer slaughter that would result,” Mcleod said. “The white tail deer is the signature species of Vermont and it would really drastically change the balance of deer in the state over time.”

Austin said the department will have to pinpoint the origin and genetic makeup of the animal before it can fully understand the implications the discovery has for Vermont.

“What we haven’t done is ask an objective wildlife genetics expert … to help us understand what all this information now means to us,” Austin said. “What are the implications of that to wildlife conservation in Vermont? We’re going to work hard to get those answers.”

A 72 lb. (32.66 kg.) canine was shot in Glover, Vermont in 1997. DNA testing found it was of Gray wolf (Canis lupus) mixed with possibly coyote and domestic dog.

Reports of sightings of unfamiliar canines in Androscoggin County, Maine go back to 1991, and just over a year ago a canine thought to fit the descriptions found in previous accounts killed by an automobile on Route 4 in that county was photographed.

New York Times:

Some 10,000 years ago, somewhere in the Near East, an audacious wildcat crept into one of the crude villages of early human settlers, the first to domesticate wheat and barley. There she felt safe from her many predators in the region, such as hyenas and larger cats.

The rodents that infested the settlers’ homes and granaries were sufficient prey. Seeing that she was earning her keep, the settlers tolerated her, and their children greeted her kittens with delight.

At least five females of the wildcat subspecies known as Felis silvestris lybica accomplished this delicate transition from forest to village. And from these five matriarchs all the world’s 600 million house cats are descended.

A scientific basis for this scenario has been established by Carlos A. Driscoll of the National Cancer Institute and his colleagues. He spent more than six years collecting species of wildcat in places as far apart as Scotland, Israel, Namibia and Mongolia. He then analyzed the DNA of the wildcats and of many house cats and fancy cats.

Five subspecies of wildcat are distributed across the Old World. They are known as the European wildcat, the Near Eastern wildcat, the Southern African wildcat, the Central Asian wildcat and the Chinese desert cat. Their patterns of DNA fall into five clusters. The DNA of all house cats and fancy cats falls within the Near Eastern wildcat cluster, making clear that this subspecies is their ancestor, Dr. Driscoll and his colleagues said in a report published Thursday on the Web site of the journal Science.

The wildcat DNA closest to that of house cats came from 15 individuals collected in the deserts of Israel, the United Arab Emirates, Bahrain and Saudi Arabia, the researchers say. The house cats in the study fell into five lineages, based on analysis of their mitochondrial DNA, a type that is passed down through the female line. Since the oldest archaeological site with a cat burial is about 9,500 years old, the geneticists suggest that the founders of the five lineages lived around this time and were the first cats to be domesticated.

Wheat, rye and barley had been domesticated in the Near East by 10,000 years ago, so it seems likely that the granaries of early Neolithic villages harbored mice and rats, and that the settlers welcomed the cats’ help in controlling them.

Unlike other domestic animals, which were tamed by people, cats probably domesticated themselves, which could account for the haughty independence of their descendants. “The cats were adapting themselves to a new environment, so the push for domestication came from the cat side, not the human side,” Dr. Driscoll said.

Cats are “indicators of human cultural adolescence,” he remarked, since they entered human experience as people were making the difficult transition from hunting and gathering, their way of life for millions of years, to settled communities.

Until recently the cat was commonly believed to have been domesticated in ancient Egypt, where it was a cult animal. But three years ago a group of French archaeologists led by Jean-Denis Vigne discovered the remains of an 8-month-old cat buried with its human owner at a Neolithic site in Cyprus. The Mediterranean island was settled by farmers from Turkey who brought their domesticated animals with them, presumably including cats, because there is no evidence of native wildcats in Cyprus.

The date of the burial far precedes Egyptian civilization. Together with the new genetic evidence, it places the domestication of the cat in a different context, the beginnings of agriculture in the Near East, and probably in the villages of the Fertile Crescent, the belt of land that stretches up through the countries of the eastern Mediterranean and down through what is now Iraq.

At issue is whether scientists who need DNA from aboriginal populations to fashion a window on the past are underselling the risks to present-day donors. Geographic origin stories told by DNA can clash with long-held beliefs, threatening a world view some indigenous leaders see as vital to preserving their culture.

They argue that genetic ancestry information could also jeopardize land rights and other benefits that are based on the notion that their people have lived in a place since the beginning of time.

Liberal egalitarianism rates not only naked savagery as equal to modern civilization, it also considers primitive cultures’ self-deluding myths as privileged from the challenge of fact.

Scientists have discovered a dramatic variation in the genetic make-up of humans that could lead to a fundamental reappraisal of what causes incurable diseases and could provide a greater understanding of mankind.

The discovery has astonished scientists studying the human genome – the genetic recipe of man. Until now it was believed the variation between people was due largely to differences in the sequences of the individual ” letters” of the genome.

It now appears much of the variation is explained instead by people having multiple copies of some key genes that make up the human genome.

Until now it was assumed that the human genome, or “book of life”, is largely the same for everyone, save for a few spelling differences in some of the words. Instead, the findings suggest that the book contains entire sentences, paragraphs or even whole pages that are repeated any number of times.

The findings mean that instead of humanity being 99.9 per cent identical, as previously believed, we are at least 10 times more different between one another than once thought – which could explain why some people are prone to serious diseases.

The studies published today have found that instead of having just two copies of each gene – one from each parent – people can carry many copies, but just how many can vary between one person and the next.

The studies suggest variations in the number of copies of genes is normal and healthy. But the scientists also believe many diseases may be triggered by an abnormal loss or gain in the copies of some key genes.

Another implication of the finding is that we are more different to our closest living relative, the chimpanzee, than previously assumed from earlier studies. Instead of being 99 per cent similar, we are more likely to be about 96 per cent similar.

Stephen Oppenheimer, one of the most prominent British autorities on DNA research, is contending that there simply isn’t all that much Norman blood around in Britain anyway, nor Celtic, nor Roman, nor Anglo-Saxon.

According to Oppenheimer,

Everything you know about British and Irish ancestry is wrong. Our ancestors were Basques, not Celts. The Celts were not wiped out by the Anglo-Saxons, in fact neither had much impact on the genetic stock of these islands…

The genetic evidence shows that three quarters of our ancestors came to this corner of Europe as hunter-gatherers, between 15,000 and 7,500 years ago, after the melting of the ice caps but before the land broke away from the mainland and divided into islands. Our subsequent separation from Europe has preserved a genetic time capsule of southwestern Europe during the ice age, which we share most closely with the former ice-age refuge in the Basque country. The first settlers were unlikely to have spoken a Celtic language but possibly a tongue related to the unique Basque language.

Another wave of immigration arrived during the Neolithic period, when farming developed about 6,500 years ago. But the English still derive most of their current gene pool from the same early Basque source as the Irish, Welsh and Scots. These figures are at odds with the modern perceptions of Celtic and Anglo-Saxon ethnicity based on more recent invasions. There were many later invasions, as well as less violent immigrations, and each left a genetic signal, but no individual event contributed much more than 5 per cent to our modern genetic mix…

based on the overall genetic perspective of the British, it seems that Celts, Belgians, Angles, Jutes, Saxons, Vikings and Normans were all immigrant minorities compared with the Basque pioneers, who first ventured into the empty, chilly lands so recently vacated by the great ice sheets.

By “Basque pioneers,” Oppenheimer is referring to female-line mitochondrial DNA haplogroup H1.

mtDNA Haplogroups in general.

Oppenheimer has a new book on all of this, titled The Origins of the British: A Genetic Detective Story.

The BBC reports:

300 volunteers to donate DNA to trace the ancestors of modern-day East Anglians.

The team at the University of East Anglia wants volunteers who were born in the same place as their parents and four grandparents.

As part of the People of the British Isles project they want to trace the influence of invaders from the Celts and Romans to the Angles and Saxons.

Volunteers from Norfolk or Suffolk will be asked to give a small blood sample.

The DNA will be extracted from the sample and used by geneticists to build the Norfolk and Suffolk part of the map.

The only criteria are that volunteers must be over 18 and born in the same part of East Anglia as their parents and all four of their grandparents.

Researchers at the university’s School of Medicine hope a genetic map of the UK will improve understanding the causes and prevalence of inherited diseases such as cancer and heart disease.

Alleged relics of Joan of Arc, burned at the stake in 1431 for witchcraft by the English, preserved by the Catholic Church in a museum owned by the diocese of Tours are to be carbon-dated and DNA-tested to investigate their authenticy by a French team of forensic scientists.
