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 on Wednesday announced plans that could hold undocumented families detained together indefinitely, replacing the agreement that set a 20-day limit for holding children.The rule unveiled by acting Homeland Security Secretary Kevin McAleenan is part of the administration's aggressive effort to revamp immigration laws as the number of families and unaccompanied minors crossing the US-Mexico border has increased.In recent months, the administration has proposed rules that could make it more difficult for immigrants to get green cards, worked to end temporary protected status for migrants from certain countries and limit avenues to declare asylum.Under what is known as the Flores settlement, the government is required to release a minor from a non-licensed facility as expeditiously as possible, which has been set at 20 days.McAleenan said the rule is meant to reduce the number of families trying to enter the US."By closing this key loophole in Flores, the new rule will restore integrity to our immigration system and eliminate the major pull factor fueling the crisis," he said at a news conference Wednesday.The proposal would give the government new licensing authority, allowing the use of either a state license or Immigration and Customs Enforcement detention standards, according to a DHS official, meaning families can be kept longer than 20 days.The regulation is certain to face legal challenges and must also be examined by the judge who oversees the Flores settlement. It will take effect 60 days after it is formally published later this week."This is yet another cruel attack on children, who the Trump administration has targeted again and again with its anti-immigrant policies," said Madhuri Grewal, policy counsel for the American Civil Liberties Union. "The government should not be jailing kids, and certainly shouldn't be seeking to put more kids in jail for longer."There has been a major influx of families and children apprehended at the southern border in recent months. Already this year, more than 430,000 family members have been arrested for crossing the southern border illegally, compared to around 100,000 for all of last year. 2205
