Neanderthals may not have been that different from us, after all.New evidence reveals that they created the world's oldest known cave paintings and even wore seashells as body ornaments. Both behaviors suggest that they thought symbolically and had an artistic sensibility like modern humans. Two studies published Thursday in the journal Science detail the latest findings."Undoubtedly it is showing that Neanderthals were thinking and behaving just like modern humans," Alistair Pike, co-author of the studies and professor of archaeological sciences at the University of Southampton, wrote in an email."We should no longer think of them as a different species, just humans in different places," he said.The new findings of symbolic thinking show that Neanderthals and modern humans were cognitively indistinguishable, the researchers said.Cave paintings and artifacts like painted seashells have long been regarded as the work of early modern humans, who were thought to have more advanced cognitive abilities than Neanderthals. Dating cave paintings can be a difficult process, and unreliable techniques never allowed for the possibility that these could be the work of Neanderthals.Until now, that is. A new technique called Uranium-Thorium dating is less destructive, is more accurate and can go back further in time than other methods. U-Th dating looks at the deposits of carbonate on top of the paint, which contain traces of uranium and thorium that indicate when those deposits formed. That allows the researchers to determine an age for what's under the deposits.The researchers applied this technique to paintings in the La Pasiega, Maltravieso and Ardales caves in Spain, which had never received "robust" dating. The paintings include red and black images of animals, dots, lines, disks and other geometric signs. There also are engravings, hand prints and hand stencils.Those hand stencils are particularly significant, and not just because they represent the hand size of a Neanderthal."A red line, a red dot or even a positive hand print could potentially be made 'accidentally,' " wrote Dirk Hoffmann, lead author of the studies and archaeologist with the Max Planck Institute for Evolutionary Anthropology, in an email."Of course, I am sure that this is not the case, since you would still need to bring [in] light and pigment, but one could argue that all you need is some pigment on your hand when you lean against a wall. A hand stencil cannot be explained like that. You have to hold your hand against the wall and the deliberately spray pigment over this. This is why we emphasize the hand stencil."The dating revealed that the cave art was created more than 64,000 years ago -- 20,000 years before modern humans appeared in what is now considered Europe.The shells were found in the Cueva de los Aviones, a sea cave in southeastern Spain. They are unique because they are perforated with holes and colored with red and yellow pigment. Others served as containers for the mineral pigments themselves. The pigments were used on the shells but could have also been used for the cave paintings and even as body paint.The deposit layer containing the shells dated to 115,000 years ago, which is even older than other shells recovered in Africa that were dated to modern humans."The standard archaeological interpretation of such finds is that they are body ornaments," Hoffmann said. "Similar finds were made in Africa or the Levant with similar age. In Africa or the Levant, these were made by modern humans, in Spain Neanderthals made them. So in terms of symbolism, early modern humans and Neanderthals were similar."The researchers are absolutely confident in their dating technique."We have spent 10 years refining the technique and have numerous quality controls," Pike said. "The dates respect the growth axis of the deposits we are dating, the oldest closest to the painting, the youngest at the surface."Once modern humans left Africa and migrated to Europe and other areas, mixing with the Neanderthals would've been inevitable. The researchers believe that the Neanderthals created this artwork on their own, without being influenced by any other population. But it's possible that they exchanged symbolism or that Neanderthals influenced the art and symbolism of modern humans. Modern humans were capable of symbolic behavior, so it "turns the who's copying who debate on its head," Pike said."The idea that culture only evolved with modern humans no longer makes sense," Pike said. Hoffmann suggested that Neanderthals now be referred to as "very close cousins" of modern humans.Is it possible that anyone else may have created the cave paintings?Pike said it is incredibly doubtful that a population of early modern humans migrated to Europe so early without any other evidence to suggest it."We cannot of course rule out that pre-Neanderthal populations made the art," Pike said. "This sounds like a project for the future."Hoffmann, Pike and their colleagues want to use their new dating technique in more caves in Spain, as well as France and Italy -- and anywhere else Neanderthals are known to lived.The findings also raise new questions for researchers."How far back does symbolic behavior go? Can it be traced to the last common ancestor of modern humans and Neanderthals? This is perhaps where we should be looking," Pike said. 5398

NASHVILLE, Tenn. (WTVF) — A Tennessee woman is calling for more oversight on the U.S. Small Business Administration loan program, saying it has made people an easy target for thieves.Pat Golab has been following the trail left behind by the people responsible for stealing her identity back in August. The last time she spoke about what happened, she shared that she was approved for the SBA Economic Injury Disaster Loan (EIDL). Not only did Golab not apply, but she doesn't have a business of her own.In the months that followed, Golab filed three reports with the SBA and the Office of the Attorney General. She finally managed to get her hands on a copy of the application and says what she found should put others on alert.Thieves used her name, address, and social security number to apply for the ,000 loan, but left virtually everything else blank.Simple questions like ethnicity, gender, and veteran status went ignored. Golab says that should have been a red flag, but it only got worse from there.“Things like, how long have you been in business? Nothing,” said Golab.Questions on prior business history and bankruptcies were left blank. These thieves claimed 12 employees were working, but also say they plan to retain none.“The application never should have been approved,” Golab said.So why was a program designed to help businesses keep their employee, paying out thousands of dollars to businesses who don’t plan on retaining anyone? That’s the question Golab has yet to have answered.“I looked on the SBA’s website on how to complete the application and one of the first things it says is every question must be answered. If not, the application will be returned and you’ll come back and you’ll start at the bottom. Which was not what they did at all,” Golab said.The loan in Golab’s name has been deferred, but she still gets letters from the SBA saying they need her to make 0 payments each month to cover the accruing interest.We contacted the SBA once again on Monday and they tell us they can’t speak in detail about individual claims.They issued this statement:“The SBA Office of Inspector General and the agency’s federal partners are working diligently to resolve Economic Injury Disaster Loan and PPP fraud incidents.Additionally, the SBA does not comment on individual borrowers. Evidence of waste, fraud, and abuse with any of SBA’s loan programs is not tolerated and should be reported.”Douglas Schmidt is a professor of computer science at Vanderbilt University and says cybercriminals are expanding their operations around the country. This makes it even more challenging to catch them in the act, and almost impossible if they are beyond the jurisdiction of local and state law enforcement.With how fast federal officials had to roll out money for unemployment programs and the SBA loans, Schmidt says it makes sense why some applications like those filed in Golab’s name could slip through the cracks.“It’s a growing problem. It's a problem that is only solved by education,” Schmidt said.If they haven’t tried already, Schmidt says thieves will send phishing emails and or calls, claiming to be one of these agencies you trust. Whatever you do, do not fall for it.Pay close attention to the email address or phone number. If you’re at all skeptical about who you’re talking to, try calling the agency back yourself to verify if they made the call in the first place.Around the holiday season, thieves will also try and use the names of people close to you. They may give you a story about a relative falling on hard time needing money. The same advice applies again. Try contacting the relative yourself, to avoid sending money to someone you do not know.Thieves may also try and convince you that your Amazon package is delayed and they need more information to verify where to send it. Stop the call, or don’t click on the email and contact Amazon directly.Click here for more information if you suspect you were the victim of SBA loan fraud.This article was written by Levi Ismail for WTVF. 4041

MOSCOW — The Kremlin says Russian President Vladimir Putin won’t congratulate President-elect Joe Biden until legal challenges to the U.S. election are resolved and the result is official.Putin is one of a handful of world leaders who have not commented on Biden’s victory, which was called by major news organizations on Saturday.However, President Donald Trump’s team has promised legal action in the coming days and refused to concede his loss. He has alleged large-scale voter fraud, so far without proof.When Trump won in 2016, Putin was prompt in offering congratulations, but his spokesman Dmitry Peskov told reporters Monday that this year’s election is different.The leaders of China, Mexico, Brazil and Turkey also are holdouts in offering congratulations.China says it has taken note of Biden's declaration of victory in the election but is holding off on sending any message of congratulations.A foreign ministry spokesperson says the result of the election would be determined under U.S. laws and procedures and that China would follow international practices in extending its sentiments.China has had a fractious relationship with Trump, characterized by growing friction over trade, technology and competition for influence in Asia and the world.Analysts say Biden will likely return ties to a less contentious state, although Beijing has stuck throughout the election to a position of not commenting directly on what it says is an internal American political issue. 1489

National leaders are launching an investigation into nursing homes and how they are handling the coronavirus crisis, specifically asking how they spent federal funds during the pandemic and their efforts to prevent further infections.Letters seeking information were sent to the Centers for Medicare and Medicaid Services, the federal agency that oversees nursing homes, as well as the five largest for-profit nursing home companies in the country. Read the letter sent to CMS here.“The Subcommittee is concerned that lax oversight by the Centers for Medicare and Medicaid Services (CMS) and the federal government’s failure to provide testing supplies and personal protective equipment to nursing homes and long-term care facilities may have contributed to the spread of the coronavirus and the deaths of more than 40,000 Americans in these facilities,” wrote Representative James E. Clyburn, the chairman of the committee.CMS Administrator Seema Verma responded to the letter on social media, linking to updated nursing home data. Click here to see the latest information. 1082

More than 200 interviews have been conducted in the investigation into the disappearance of University of Iowa student Mollie Tibbetts, according to the special agent in charge.Tibbetts, 20, disappeared nearly two weeks ago in Brooklyn, a small community an hour east of Des Moines, according to the Poweshiek County Sheriff's Office.The hundreds of interviews are related to tips investigators have received, said Richard Rahn, the special agent in charge with the Iowa Division of Criminal Investigation for the Major Crime Unit. The sheriff's office is scheduled Tuesday to give an update on the investigation."People are concerned and wanting to help," Rahn said. "We welcome the phone calls and are doing everything."Investigators are continuing to evaluate data, going over the leads list, and having agents in the field to locate Tibbetts. Data includes social media and information from a Fitbit that Tibbetts is known to have."We live in a digital world," Rahn told CNN sister network HLN. "We'll look at cell phones, computers, social media sites, and everyone knows there's a Fitbit involved as well. We look at that, try to establish a timeline as best we can. We feel we have done that thus far."Investigators executed search warrants for Tibbetts' Fitbit, which she was known to wear, and her Snapchat, Instagram and Facebook accounts, Mitch Mortvedt, spokesman for the Iowa Division of Criminal Investigation, said last week. 1453
