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

Thousands of pro-gun rights activists converged around the Virginia Capitol on Monday to voice opposition to gun control legislation proposed by the Democratic-held legislature.Among the vocal critics of the bills were members of law enforcement, who used their official office to advocate against some of the proposals. The Grayson County Sheriff’s Office posted on its Facebook page its support for the protest. The sheriff’s office also posted photos of deputies in uniform holding a sign saying, “we support the second amendment.”“Great turnout for 2A rally in Richmond today! Standing room only!!” the post read. Culpeper County Sheriff Scott Jenkins also attended the rally to show his support. He said he would deputize gun owners if Virginia lawmakers move forward with gun legislation. It is unclear if said deputies would have arrest power.“My intent was to swear in thousands of auxiliary deputy sheriffs and make it legal for them to possess the weapons that they're trying to ban and restrict,” Jenkins said. Dozens of sheriffs in Virginia have stated that their departments would not enforce gun laws they feel are unconstitutional. Jenkins suggested, but would not directly answer, whether his department would enforce state laws involving gun control if Democrats move forward with legislation.“I'll have to make a determination if these laws they pass or a violation of that,” Jenkins said. Although thousands gathered in Richmond to protest gun legislation, Gov. Ralph Northam said there was a reason why Democrats were elected in Virginia. In his State of the Commonwealth address earlier this week, Northam referenced the legislature’s response to a mass shooting at a Virginia Beach municipal complex last year as a reason why Democrats gained a majority in the Virginia House for the first time in nearly three decades. “Virginians watched. They saw what happened, and they were appalled. So they changed the legislature. And here we are,” Northam said. While a bill to ban assault weapons was dropped earlier last week, other bills are still being considered. One is limiting the purchases of firearms to one a month.Earlier this month, Northam signed legislation to prohibit firearms inside of the Capitol building and an adjacent legislative office building. Another one of the more controversial bills is a so called “red flag” law, which would allow for law enforcement to take away firearms from gun owners who are considered a danger to themselves or others. Northam defended this legislation as “constitutional.” “If you have demonstrated extreme risk of violence, or there’s a protective order against you, you shouldn’t have a firearm. This means universal background checks. If there’s nothing in your record, you have nothing to worry about,” the governor said. Jenkins isn’t convinced. “Right now, it's hard to say that we're going to disarm our citizens who often have a 10- or 15-minute response time in rural areas for an officer to arrive and say we're going to disarm the homeowner and restrict their rights to defend themselves,” the sheriff said.

The U.S. Department of State issued a travel advisory on Monday for those planning trips to South Korea. The advisory is considered a "Level 2" advisory, on a scale from Level 1 to Level 4. A Level 2 advisory encourages travelers to "exercise increased caution" before going to the region."Many cases of COVID-19 have been associated with travel to or from mainland China or close contact with a travel-related case, but sustained community spread has been reported in South Korea," the State Department said. "Sustained community spread means that people in South Korea have been infected with the virus, but how or where they became infected is not known, and the spread is ongoing."The Associated Press has reported a total of 893 cases of coronavirus in South Korea. Last month, the State Department issued a Level 4, or "do not travel" advisory for those making trips to China. 895

  

The United States Postal Service (USPS) and their unions continue to raise an alarm about their dire financial situation. According to the USPS officials, they are losing around billion per month amid the COVID-19 pandemic. A recent release said the financial situation is “threatening their ability to operate.”The problemWhile package deliveries are up, business mailings are down, which is how USPS makes most of its money. "It is a dire situation, Mark Dimondstein, president of the American Postal Workers Union, said. "The post office does not run on any tax dollars; it runs on the revenue generated by postage and postal products."Dimonstein says the postal service could run out of money by fall. Bailout? USPS has asked Congress for a billion bailout. While a billion funding package has passed the House, it has so far not passed the US Senate. The American Postal Workers Union has launched a rare television advertisement asking Americans to call Congress. 993
