The remains of an ancient ape found in a Bavarian clay pit suggest that humans’ ancestors began standing upright millions of years earlier than previously thought, scientists said Wednesday.An international team of researchers says the fossilized partial skeleton of a male ape that lived almost 12 million years ago in the humid forests of what is now southern Germany bears a striking resemblance to modern human bones. In a paper published by the journal Nature, they concluded that the previously unknown species — named Danuvius guggenmosi — could walk on two legs but also climb like an ape.The findings “raise fundamental questions about our previous understanding of the evolution of the great apes and humans,” said Madelaine Boehme of the University of Tuebingen, Germany, who led the research.The question of when apes evolved bipedal motion has fascinated scientists since Charles Darwin first argued that they were the ancestors of humans. Previous fossil records of apes with an upright gait — found in Crete and Kenya — dated only as far back as 6 million years ago.Boehme, along with researchers from Bulgaria, Germany, Canada and the United States, examined more than 15,000 bones recovered from a trove of archaeological remains known as the Hammerschmiede, or Hammer Smithy, about 70 kilometers (44 miles) west of the Germany city of Munich.Among the remains they were able to piece together were primate fossils belonging to four individuals that lived 11.62 million years ago. The most complete, an adult male, likely stood about 1 meter (3 feet, 4 inches) tall, weighed 31 kilograms (68 pounds) and looked similar to modern-day bonobos, a species of chimpanzee.“It was astonishing for us to realize how similar certain bones are to humans, as opposed to great apes,” Boehme said.Thanks to several well-preserved vertebra, limb, finger and toe bones, the scientists were able to reconstruct how Danuvius moved, concluding that while it would have been able to hang from branches by his arms, it could also straighten its legs to walk upright.“This changes our view of early human evolution, which is that it all happened in Africa,” Boehme told The Associated Press in an interview.Like humans, Danuvius had an S-shaped spine to hold its body upright while standing. Unlike humans, though, it had a powerful, opposable big toe that would have allowed it to grab branches with its foot and safely walk through the treetops.Fred Spoor, a paleontologist at the Natural History Museum in London, called the fossil finds “fantastic” but said they would likely be the subject of much debate, not least because they could challenge many existing ideas about evolution.“I can see that there will be a lot of agonizing and re-analysis of what these fossils mean,” said Spoor, who wasn’t involved in the study. 2833

The State Department ordered Wednesday the departure of non-emergency US government employees from Iraq amid increasing tensions with Iran and warned US citizens not to travel to the country, citing a "high risk for violence and kidnapping."The department said in a statement that employees working in the US embassy in Baghdad and the US consulate in Erbil were instructed to leave Iraq, and that "normal visa services will be temporarily suspended at both posts."It added that American Citizens Services employees who were working in the embassy in Baghdad "will continue to provide consular services to U.S. citizens in Basrah."The department said the sudden changes were because the US government's "ability to provide routine and emergency services to US citizens in Iraq is extremely limited" and that as a result, the threat of "terrorism, kidnapping, and armed conflict" aimed at Americans in the country was too great a risk.Secretary of State Mike Pompeo made an unannounced visit to Iraq last week amid escalating tensions with Iran.While there, Pompeo said he spoke to Iraqi officials "about the importance of Iraq ensuring that it's able to adequately protect Americans in their country."US officials have told CNN the US had "specific and credible" intelligence that suggested Iranian forces and proxies were planning to target US forces in locations including Iraq. That intelligence led the Pentagon to recommend a carrier strike group be moved to the region.The State Department also said Wednesday that Americans "should not travel through Iraq to Syria to engage in armed conflict" as they may face similar threats in Syria and face "legal risks" from both the US and Syria.The orders from the State Department come a day after US Central Command, which oversees US military operations in the Middle East, said in a statement that the Pentagon has increased the threat risk for US troops in Iraq and Syria."US Central Command, in coordination with Operation Inherent Resolve, has increased the force posture level for all service members assigned to OIR in Iraq and Syria. As a result, OIR is now at a high level of alert as we continue to closely monitor credible and possibly imminent threats to US forces in Iraq," US Navy Capt. Bill Urban, a spokesman for Central Command, said in a statement Tuesday.Urban's statement also pushed back against comments made earlier Tuesday by the deputy commander of the US-led military coalition against ISIS, UK Major Gen. Chris Ghika, who said "there has been no increased threat from Iranian backed forces in Iraq and Syria." 2598

The violent tornado that hit Jefferson City overnight "felt like an earthquake," says one Missouri woman who lived through it https://t.co/K3tpNua9PH— CNN (@CNN) May 23, 2019 186

Trucker David Bell was hauling nearly 45,000 pounds of soda in his tractor-trailer through Jefferson City, Missouri, when his smart phone sprang to life with a severe weather alert.He pulled over to the side of the road, as a tornado spread mass chaos outside. The windscreen of the truck's cab shattered. The howling winds blew part of a house underneath his trailer and trees snapped as lightning flashed around him.Agape at nature's fury around him, he wondered that Thursday night whether he'd see his family again."It definitely gave me a new outlook on life," 578
