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 Trump administration told Congress it intends to dramatically cut the number of refugees it will admit in the next fiscal year, only up to 18,000 refugees, according to the State Department -- marking a historic low and threatening to further erode the nation's refugee resettlement program.Under President Donald Trump, the administration has slowly chipped away at the refugee cap, which dictates how many refugees may be admitted to the United States. The ceiling for fiscal year 2019 stands at 30,000, which, at the time, was the lowest level since 1980.The State Department announced the proposed refugee ceiling as part of a larger number of combined refugee and asylum claims expected for the next fiscal year.In a call with reporters, senior administration officials said the report submitted to Congress allocates admissions by "group of special humanitarian interests to the United States," instead of by region -- including Iraqis who assisted the United States, those who have suffered or feared religious persecution, and nationals of Guatemala, Honduras and El Salvador.The White House also released an executive order Thursday that requires state and local governments to consent to receiving refugees, with some exceptions. Refugee resettlement agencies are charged with placing refugees around the country, but the new executive order could allow states and local jurisdictions to deny refugees entry.The move continues the administration's push to limit the number of people admitted to the US and comes after discussion that some in the White House wanted to let 1597

This year’s Memorial Day weekend at Lake of the Ozarks businesses was “busier than any year,” according to one proprietor.Robin's Resort owner Bill Morgan said that most people at his business “were practicing social distancing,” though the size of the crowds – including those seen in a viral video that circulated over the weekend – were not surprising."What you saw in that video is the norm for those types of places even without what's going on now,” Morgan said.Local health experts, however, see large gatherings as a concern as phased reopenings are underway. They said activities seen in videos from the Lake of the Ozarks are risky, even if you're healthy."Those large groups with strangers, you may never have contact with someone again and know if they get symptoms in a couple of days,” Dr. Sarah Boyd, an infectious disease physician at St. Luke's Health System, said. “Those things all just increase that risk of spread to other parts of our communities.”Experts like Ray Dlugolecki, of the Jackson County Health Department, stressed the need to take proper precautions for oneself and neighbors."It would be disastrous to move backwards because we can't take part in sensible precautions like mask wearing, social distancing, hand washing," Dlugolecki said.Larry Giampa, owner of Blondies Burger Bar, is concerned about those crowds."I'm worried about the virus,” he said. “I'm 68. My wife is 66. And what worried me is all the Chicago, St. Louis and Kansas City and other areas that came in this weekend. I'm worried about it. I'm worried for my employees getting sick."The Camden County Sheriff's Office released a statement on Monday, that said "social distancing is not a crime and there the sheriff's office has no authority to enforce." It also said that the sheriff’s office hopes visitors "exhibit personal responsibility when at the lake.This article was written by Dan Cohen for 1917
