    The oldest ever recovered DNA samples have been collected from under more than a mile of Greenland ice, and their analysis suggests the island was much warmer during the last Ice Age than previously thought. The DNA is proof that sometime between 450,000 and 800,000 years ago, much of Greenland was especially green and covered in a boreal forest that was home to alder, spruce and pine trees, as well as insects such as butterflies and beetles.

    Source: University of Copenhagen Date: July 5, 2007 Fossil DNA Proves Greenland Once Had Lush Forests; Ice Sheet Is Surprisingly Stable Science Daily ó Ancient Greenland was green. New Danish research has shown that it was covered in conifer forest and, like southern Sweden today, had a relatively mild climate. Eske Willerslev, a professor at Copenhagen University, has analysed the world's oldest DNA, preserved under the kilometre-thick icecap. The DNA is likely close to half a million years old, and the research is painting a picture which is overturning all previous assumptions about biological life and the climate in Greenland....

    Landmark new research that involves analyzing millions of DNA barcodes has debunked much about what we know today about the evolution of species. In a massive genetic study, senior research associate at the Program for the Human Environment at Rockefeller University Mark Stoeckle and University of Basel geneticist David Thaler discovered that virtually 90 percent of all animals on Earth appeared at right around the same time. More specifically, they found out that 9 out of 10 animal species on the planet came to being at the same time as humans did some 100,000 to 200,000 years ago. "This conclusion...

    On a rugged bluff overlooking the Ohio River, known locally as "Devil's Backbone," centuries of overgrowth obscures a secret of history... In 1799, early settlers found six skeletons clad in breastplates bearing a Welsh coat of arms. Indian legends told of "yellow-haired giants" who settled in Kentucky, southern Indiana, southern Ohio and Tennessee -- a region they called "the Dark and Forbidden Land." Archeologists debunk the legend. They say that evidence indicates that the natives of the region once conducted a vigorous trading network nearby and buried their dead on the bluff...

    Ancient DNA recovered from a series of skeletons in central Germany up to 7500 years old has been used to reconstruct the first detailed genetic history of modern Europe. The study, published today in Nature Communications, reveals a dramatic series of events including major migrations from both Western Europe and Eurasia, and signs of an unexplained genetic turnover about 4000-5000 years ago. The research was performed at the University of Adelaide's Australian Centre for Ancient DNA (ACAD). Researchers used DNA extracted from bone and teeth samples from prehistoric human skeletons to sequence a group of maternal genetic lineages that are...

  • Ancient Skeletons Reveal Genetic History Of Central Europe

    In genetics, itís not just the living who advance the field: DNA preserved in the brittle bones of our ancestors can provide significant insight into our genetic history. Such is the case with a new genetic history of Europe, traced by an international team of researchers and published today in Science. By creating a seamless genetic map from 7,500 to 3,500 years ago in one geographic region, scientists discovered that the genetic diversity of modern day Europe canít be explained by a single migration, as previously thought, but by multiple migrations coming from a range of areas in modern day...

    ...In recent years, dental calculus has emerged as an unexpected, but valuable, long-term reservoir of ancient DNA from dietary and microbial sources... Very little dental calculus was required for analysis--fewer than 25 milligrams per individual. This makes it possible to obtain high quality genetic ancestry information from very little starting material, an important consideration for archaeological remains... Although dental calculus preserves alongside skeletal remains, it is not actually a human tissue. Dental calculus, also known as tartar, is a calcified form of dental plaque that acquires human DNA and proteins passively, primarily through the saliva and other host secretions. Once...

    From the paper: In 1808 the Portuguese Crown declared ďJust WarĒ (Bellumiustum) against all Indian tribes that did not accept European laws (23). The fierce Botocudo were targeted in such wars and, in consequence, became virtually extinct by the end of the 19th century (24). Their importance for the history of the peopling of the Americas was revealed by studies reporting that the Botocudo had cranial features that consistently were described as intermediate between the polar Paleoamerican and Mongoloid morphologies (25, 26). Multivariate analyses of the cranial measures of different Amerindian and Paleoamerican groups from Brazil indeed concluded that the...

    DNA evidence lifted from the ancient bones and teeth of people who lived in Europe from the Late Pleistocene to the early Holocene -- spanning almost 30,000 years of European prehistory -- has offered some surprises, according to researchers who report their findings in the Cell Press journal Current Biology on Feb. 4, 2016. Perhaps most notably, the evidence shows a major shift in the population around 14,500 years ago, during a period of severe climatic instability... The researchers pieced this missing history together by reconstructing the mitochondrial genomes of 35 hunter-gatherer individuals who lived in Italy, Germany, Belgium, France,...

    Jean-Marie Loret, who died in 1985 aged 67, never met his father, but went on to fight Nazi forces during the Second World War. His extraordinary story has now been backed up by a range of compelling evidence, both in France and in Germany, which is published in the latest edition of Paris's Le Point magazine. Hitler is said to have had an affair with Mr Loret's mother, Charlotte Lobjoie, 16, as he took a break from the trenches in June 1917. Although he was fighting the French near Seboncourt, in the northern Picardy region, Hitler made his way to...

    Until his death in 1985, Jean-Marie Loret believed that he was the only son of Adolf Hitler. There is now renewed attention to evidence from France and Germany that apparently lends some credence to his claim. Loret collected information from two studies; one conducted by the University of Heidelberg in 1981 and another conducted by a handwriting analyst that showed Loretís blood type and handwriting, respectively, were similar to the Nazi Germany dictator who died childless in 1945 at age 56. The evidence is inconclusive but Loretís story itself was riveting enough to warrant some investigation. The French newspaper Le...

    Today, he believes Germany is doomed. "People there don't get married, and if they do they have one child," he says. "But the Turks and the other foreigners have many children. So it is a question of time that Germany will no longer be German." Why does he think this has happened? "I think it is a punishment for the Holocaust," he says, matter-of-factly. "Germany will leave the stage of history, no doubt about it." But the Jews, by contrast, will never die. This is a neat irony of history that he loves. "All the great cultures have left the...

    Getting to know the Hitlers (Filed: 20/01/2002) FOR more than 50 years, the relatives of Adolf Hitler have hidden under false names in Long Island, New York. They have not spoken publicly since the Second World War. In a revelatory new book to be launched this week, they break their silence. David Gardner tells their story. The faint lilt of German folk music floated through the open window of the dark-wood alpine bungalow as I walked down the short path to the front door. The property straddled two small roads on a forested private estate nestling into one of the ...

    Matias Goering is a direct descendant of Hitler's right-hand man and the commander of the Nazi air force. He also keeps Shabbat, wears a kippa, and identifies with the Greater Israel vision of West Bank settlers If Field Marshall Hermann Goering, commander of the Nazi Air Force and Hitler's right-hand man, knew how his descendant Matias Goering was living today, he'd surely roll over in his grave.

    DNA tests have revealed Adolf Hitler may have been related to both Jews and black people that he earmarked for extermination. Brussels news magazine Knack has claimed that DNA obtained from the Nazi leader's relatives living in America led to the discovery. Journalist Jean-Paul Mulders garnered the DNA from a serviette dropped by one of three known Hitler descendants who live on Long Island, New York. That led earlier this year to the tracking down in Austria of a farmer known only as Norbert H. who was found to be a cousin of the German dictator. Mulders used the services...

    Geneticists from the University of Leicester have discovered that most European men descend from just a handful of Bronze Age forefathers, due to a 'population explosion' several thousand years ago. The project, which was funded by the Wellcome Trust, was led by Professor Mark Jobling from the University of Leicester's Department of Genetics and the study is published in the journal Nature Communications. The research team determined the DNA sequences of a large part of the Y chromosome, passed exclusively from fathers to sons, in 334 men from 17 European and Middle Eastern populations. This research used new methods for...

    Characteristics passed between generations are not decided solely by DNA, but can be brought about by other material in cells, new research shows. Scientists studied proteins found in cells, known as histones, which are not part of the genetic code, but act as spools around which DNA is wound. Histones are known to control whether or not genes are switched on. Researchers found that naturally occurring changes to these proteins, which affect how they control genes, can be sustained from one generation to the next and so influence which traits are passed on. The finding demonstrates for the first time...

    Scientists now know that our DNA is being altered all the time by environment, lifestyle and traumatic events. Genetic faults caused by trauma, poor lifestyle or environmental stress can be passed down to future generations, scientists at the University of Cambridge have discovered. Previously large studies have shown that devastating events such as famine can scar future generations, making them more prone to obesity and diabetes. However it is the first time that the biological mechanism for the effect has been seen. Although the same genes are passed down through generations, scientists now know that our DNA is being altered...

    Graham Williams at the University of Huddersfield, UK, has a different way Ė to look for modifications to the twins' DNA that have come about as a result of their lifestyles. Such epigenetic changes occur when a chemical group known as a methyl group attaches to a gene and modifies the way it is expressed. This happens as a body is influenced by a person's environment, lifestyle and disease. Williams's team took mouth swabs from five pairs of twins. After extracting the DNA from each sample, the group used a chemical to target parts of the DNA that did not...
