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 Taliban is claiming responsibility following the death of a US service member in Afghanistan on Monday, even as peace negotiations between the Taliban and US continue.US and Afghan government forces were targeted with IEDs while conducting a raid in the northern province of Kunduz, according to Taliban spokesman Zabiullah Mojahid.The US military early Monday confirmed that a service member was killed in action. The name is being withheld until next of kin is notified.Between 12,000 and 13,000 US troops are currently serving in Afghanistan as part of a US-led NATO mission to train, assist and advise Afghan forces.At least 20 Americans have been killed in combat in Afghanistan in 2019, and there have been more than 2,400 total deaths of US service members since the start of the 18-year war.The Taliban has continued to carry out attacks despite ongoing peace talks with the US.President Donald Trump announced late last month 951

The Trump administration plans to shift at least 5 million from the Federal Emergency Management Agency disaster relief fund to support its policy of returning some migrants to Mexico.The Department of Homeland Security has informed Congress it will reprogram and transfer 1 million in total to its immigration enforcement agency from elsewhere in the department, including the FEMA money, according to documents obtained by CNN.The moves comes as Hurricane Dorian nears a Category 4 status.Last week, the administration announced its intention to hold migrant families indefinitely, aimed at scrapping a settlement that put a 20-day limit on family detention.DHS notified Congress of its plan to reprogram and transfer funds from agencies over to Immigration and Customs Enforcement, DHS' enforcement arm, on July 26, according to a DHS official. The department plans to transfer around 6 million for ICE detention beds, as well as transportation and deportation, the official said.The department will not pull funds for detention beds from the US Secret Service, the Office of the Inspector General, and the Office of Intelligence and Analysis."In this case, this is a must-pay bill that needed to be addressed," said the official."We would not say that this is with no risk," said the official, who added that it was done in ways to "minimize the risk" to agencies that are losing funding.FEMA said in a statement to CNN, "This transfer of funds to support the border emergency will leave a remaining balance of 7 million in the DRF (Disaster Relief Fund) Base account. Based on DHS and FEMA's review of historical emergency spending from the DRF Base account, this amount will be sufficient to support operational needs and will not impact ongoing long-term recovery efforts across the country. The DRF Majors account, which provides funding for ongoing recovery efforts, including those supporting communities impacted by the 2017 disasters, has a current balance of approximately billion and is not impacted by the reprogramming."It's not uncommon for departments, including DHS, to reprogram funds. DHS, in particular, has previously reprogrammed funds for detention beds, for example.The reprogramming of money to Immigration and Customs Enforcement is sure to receive pushback from Democratic lawmakers who've criticized the agency.In a letter to acting Homeland Security Secretary Kevin McAleenan, Democratic Rep. Lucille Roybal-Allard of California, chair of the House Homeland Security Appropriations Subcommittee, opposed the reprogramming of funds, saying she had "significant concerns about the intended use of funds" and the shifting of funds from other components.House Homeland Security Chairman Bennie Thompson said in a statement that the administration is "flouting the law and Congressional intent to fund its extremist indefinite detention immigration policies.""Taking money away from TSA and from FEMA in the middle of hurricane season could have deadly consequences. Congress should work to undo the damage this Administration is continually doing to our homeland security infrastructure," the Mississippi Democrat added.DHS plans to transfer .8 million from the Transportation Security Administration for immigration enforcement, according to a document obtained by CNN.Earlier this year, funds for additional detention beds -- as the administration has repeatedly pushed for -- became a sticking point in appropriations negotiations.Democrats argued that by allowing ICE to up the number of detention beds, the agency would have the capacity to pursue a broader population of undocumented immigrants, including those without criminal records. But Republicans view the number of detention beds as central to limiting the release of detained undocumented immigrants into the US as they await hearings.In the end, the spending bill included funding for an average 45,274 detention beds per day, with the intent to return to 40,520 by the end of the fiscal year, which is the level funded in the last fiscal year, but short of the administration's request of 52,000 detention beds. The reprogramming of funds will up ICE's bed count to roughly 50,000.In recent months, however, the agency has been consistently holding more people in detention: As of August 10, 55,530 people were in immigration detention, according to the agency.Last year, the department was also sharply criticized for shifting around million from the Federal Emergency Management Agency's operating budget to fund immigration detention and deportations. The administration also quietly redirected 0 million from multiple parts of DHS to ICE last summer, according to a congressional document released last fall.The latest shift in funds will also pull more money from FEMA -- .4 million for detention efforts.Additionally, .3 million will be transferred from DHS' cyber agency.DHS resources have been stretched thin amid an influx of migrants at the southern border. So far this fiscal year, more than 760,000 migrants have been arrested for crossing the border illegally. Many of them turn themselves in to agents.In May, the Trump administration asked Congress for .5 billion in emergency funding. The request included additional detention beds. That part of the request was not fulfilled. 5330

The suspected driver in the shooting death of 7-year-old Jazmine Barnes will be held without bail, a Texas judge ruled Monday.Eric Black Jr., 20, did not speak during the five-minute probable cause hearing in Harris County court. Wearing a yellow jail jumpsuit, his hands and feet shackled, he sat in the jurors' box during the proceeding with at least a half-dozen deputies in tactical vests standing before him.The Harris County Sheriff's Office said Saturday it filed capital murder charges against the 20-year-old, but it was not clear if he has been formally charged by the court. Black was not required to enter a plea Monday.His attorney, Alvin Nunnery, entered a motion saying Black invoked his Fifth Amendment rights and should no longer be interviewed by investigators. The motion was granted.Prosecutors said Black has confessed to driving the car from which Jazmine was shot December 30 in Houston, and a gun found at his home was consistent with eight shell casings found at the scene. Black and the suspected shooter mistook the car carrying Jazmine for a car belonging to someone with whom the pair had had an earlier altercation at a club, prosecutors said.Black's mother wept and clutched a family member's hand during the hearing. Black mouthed "I love you" to family members as he left the courtroom.Police: Traffic stop led to confessionBlack was pulled over for failing to use a turn signal Saturday night and was arrested for marijuana possession, Texas authorities said.Thanks to an earlier anonymous tip, police learned Black might have been involved in the drive-by shooting of Jazmine, who was shot in the head while riding in a car with her three sisters and their mother.The anonymous tipster said Black and another person, identified as "L.W.," shot at the vehicle after mistaking it for another one.During questioning, Black acknowledged he drove the vehicle used in the shooting while a man in the passenger seat opened fire, according to an affidavit.Black also said the gun used in the shooting was at his home, the affidavit said. He gave officers permission to search his home, where they found a 9 mm pistol consistent with shell casings recovered from the scene.The fate of "L.W." is not clear.Harris County Sheriff Ed Gonzalez said he believes two suspects were involved in the shooting.The sheriff declined to name the second person, citing the investigation. Prosecutors identified Larry Woodruffe as the second suspect in a court hearing Saturday, the 2505
