Naia: 12,500-Year-Old Skeleton Sheds Light on First Americans In an underwater cave chamber in Mexico, the 12,000-year-old bones of a girl named Naia have preserved clues to the origins of the First Americans. Was it a spectacular celestial discoveryor just a fluke? She has the physical characteristics we expect to see in Paleoamericans, and the genetics say she and modern Native Americans share ancestry, says James Chatters, an archaeologist who has studied both Naia and Kennewick Man. The genetic verdict was the clincher: Mitochondrial DNA extracted from one of Naia's teeth confirmed a common genetic lineage with the ancient Beringians and modern-day Native Americans. But paleontologists still know very little about this massive interchange, since fossils are notoriously hard to come by in the tropical forests that cover the region. Facial reconstruction resulted in someone who looked a bit like the actor Patrick Stewart ("Star Trek: The Next Generation," "X-Men"). Learn how your comment data is processed. But therein lies a puzzle: "Modern Native Americans closely resemble people of China, Korea, and Japan but the oldest American skeletons do not," says archaeologist and paleontologist James Chatters, lead author on the study and the owner of Applied Paleoscience, a research consulting service based in Bothell, Washington. Was this prehistoric killer shrimp as fierce as it looked? The . The radiocarbon dating of the DNA tooth enamel yielded a maximum age for Naia of 12,900 years ago. As the cave divers drifted down through the dark waters of the Mexican sinkhole, they first spotted large boulders piled on the floor. Three-fifths of a mile from the cave entrance, having penetrated a narrow tunnel, the divers came upon an astonishing sight: a massive pit, at least 150-feet deep.
Mexican skeleton gives clue to American ancestry A team of science divers led by Alberto Nava Blank from Proyecto de Espeleologia de Tulum discovered the skeleton along with remains of giant ground sloths, gomphotheres, saber-toothed cats and many other extinct animals deep inside a submerged chamber in the Sac Actun cave system in the eastern Yucatan Peninsula, Mexico, in 2007. The shape of Naia's skull and the DNA in her bones have led researchers to the conclusion that there was only one major migration to the Americas, over an ancient land bridge that spanned what is now the Bering Strait. How can we keep homes cool in extreme heat without air conditioning? [2], The remains have been described as the "oldest, most complete and genetically intact human skeleton in the New World".
Mexico to extract 13,000-year-old 'Naia' skeleton from cave (2014)Cite this article. For more than 12,000 years, the adolescent girl's bones lay deep in a Mexican cave. Researchers focused especially on haplotypes, which are sequences of genes that mutate more slowly than the rest of the mtDNA. Heres what you need to know. but also has created an image of Naia, the 15-year-old girl whose remains were discovered by scuba divers. Scientists examined material scraped from the surface of the bones, and used multiple techniques to probe one of Naias molars. But for Naia, who may have been seeking fresh water in the cavern and accidentally plunged into the sinkhole and could find no escape, it must have been a terrifying experience, he said. At that early period of time, the caves of that region, about five miles from the Caribbean Sea, were not yet filled with water. Female skeletons from the Americas have been frustratingly incomplete, says Chatters. Why did Naia go into the cave? Tooth enamel also contains trace amounts of uranium and thorium, radioactive minerals that decay at known rates. He and his two fellow divers gave the girl a name: Naia. They called her Naia, after the naiads, the. A diver examines stones stacked into a pile by ancient miners who extracted ocher pigment at La Mina, a site deep inside a . Copyright 1996-2015 National Geographic Society, Copyright 2015-2023 National Geographic Partners, LLC. It ultimately resulted in a victory for the people of Mexico. In a race against time and the enemy, J. Robert Oppenheimer helped lead the U.S. effort to build the atomic bomb. "You can imagine a young woman either lost in the dark in a cave [or] she may have been looking for water, even with a group looking for water, and getting water out of the little puddle that was in the bottom of Hoyo Negro periodically, and fallen in.
Naia (skeleton) This year, scientists announced what Naias remains revealed. Scientists believe that the teenage girl was probably hunting for water when she must have fallen into a pit within the cave system. This is a long way from the big game hunters at least successful ones we expect to see in this early time.. In the darkness she must not have seen the enormous pit looming in front of her. To many, that conclusion comes as no surprise. Late Pleistocene Human Skeleton and mtDNA Link Paleoamericans and Modern Native Americans.
Mexico's 12,000-Year-Old Skeleton Analyzed - Archaeology Haplogroup D (mtDNA) is believed to have arisen in Asia. Expeditions through the years have mapped at least 28 animal skeletons within the pit, only a handful of which have been fully excavated. It helped that the cave she was found ina submerged chamber called Hoyo Negro (Spanish for black hole) of the Sac Atuncave system, accessible only by divers climbing down a 30-foot ladder in a nearby sinkhole, swimming along a 200-foot tunnel, then making a final 100-foot dropwas littered with fossils of saber-toothed tigers, giant ground sloths, cave bears and even an elephant-like creature called a gomphothere. It helps support the consensus view, from archaeological, genetic and linguistic evidence, that the Americas were initially peopled 15,00020,000 years ago from Siberia, says human geneticist Chris Tyler-Smith from the Wellcome Trust Sanger Institute near Cambridge, UK. More than 12,000 years later, in 2007, after the seas had risen and the cave system had filled with water, her skull upside down, teeth remarkably intact caught the eye of a man in scuba gear.
Divers Find Ice Age Megafauna Remains in Underwater Mexican Cave Without sufficient knowledge, preparation, and equipment, cave exploring can lead to serious injury or death. and JavaScript. Its only the fourth known deep-sea octopus nursery in the worldand may harbor a species never before identified. Archaeologist Pilar . A team of science divers led by Alberto Nava Blank from Proyecto de Espeleologia de Tulum discovered the skeleton along with remains of giant ground sloths, gomphotheres, saber-toothed cats and many other extinct animals deep inside a submerged chamber in the Sac Actun cave system in the eastern Yucatan Peninsula, Mexico, in 2007. [2] Nabia was worshipped in many places on the Iberian Peninsula, sometimes in very different ways, leading some historians to suggest that "Nabia" was just a common word . But the researchers needed to get more specific than that.
Cave rescue: Key questions answered - BBC News Late Pleistocene Human Skeleton and mtDNA Link Paleoamericans and Modern Native Americans. Naia's remains were found in an underwater cave so huge, deep, and dark that researchers named it Hoyo Negro or Black Hole. Our graphics team has done a great job putting together not only a diagram of the cave and illustrations of what has been found there saber-toothed cats, lots of bears, etc.
DNA From 12,000-Year-Old Skeleton Helps Answer the Question: Who Were When you start out with a little bit of data, its easy to spin a simple scenario, says Greg McDonald, a U.S. Bureau of Land Management paleontologist and a member of the Hoyo Negro team. A tunnel runs 20 metres below ground and opens into the top of the chamber, 30 metres above the floor. The rescue. All Rights Reserved. Unlike previous skeletons of early Americans, Naias included her teeth. The migration is thought to have started during the Pleistocene ice age which ended around 14,000 years ago and continued over the next several thousand years as these populations moved south. Big roll-out in Science, with a teleconference highlighted by a couple of questions from the legendary science journalist David Perlman (look him up thats the guy I want to be in my 90s!). Why did these shark hunters bury their dead with extra limbs? The project will be featured in National Geographic magazine and on a National Geographic Television program airing as part of PBS' "Nova" documentary series in 2015. Naia is important, however, because her DNA does, in fact, have much in common with those Bering Sea travelers demonstrating that the differences in appearance in early skeletons do not necessarily support theories of alternative entries into the Americas. Google Scholar, You can also search for this author in Analysis of these florets agreed with other readingsNaia fell into cave no earlier than 12,000 years ago. Nabia (or Navia) was a goddess of the Pre-Roman peoples of the Iberian Peninsula, although she also had an extended cult during the Roman occupation of the peninsula.

Recent locally acquired cases in Florida and Texas have raised concerns about a rise in mosquito-borne diseases. Now it is entirely flooded, the water mostly fresh. Prevailing ideas point to all Native Americans descending from ancient Siberians who moved across theBeringia land bridgebetween Asia and North America between 26,000 and 18,000 years ago. More than 12,000 years later, in 2007, after the seas had risen and the cave system had filled with water, her skull upside down, teeth remarkably intact caught the eye of a man in scuba gear. Whether you arrive by caravan. mtDNA is more abundant than DNA found in a cells nucleus, so its easier to study. Researchers add that she was about 5 feet (1.5 meters .

For more than 12,000 years, the adolescent girl's bones lay deep in a Mexican cave. Naia, as she's known today, likely fell to her death in a deep, dark pit. How vulnerable are we? In the meantime, to ensure continued support, we are displaying the site without styles | READ MORE. He compared the cave, known as Hoyo Negro (black hole), to the Awash Valley of Ethiopia the site of the 1974 discovery of Lucy, an early human ancestor. Some are found in cliffs at the edge of the coastline, chipped away by the relentless pounding of waves. This is a long way from being a settled matter, as youd expect with such a hot scientific topic. [4], The report concluded that "HN5/48 shows that the distinctive craniofacial morphology and generalized dentition of Paleoamericans can co-occur with a Beringian derived mtDNA haplogroup.

Thus, according to the new report, the Native Americans and the Paleoamericans are the same people; they just look different because of evolutionary changes. Revelations made this past spring about her DNA make this 13,000-year-old girl (name "Naia" by those who discovered her) one of the most extraordinary archeological finds in Mexico. She lies in a collapsed chamber together with the remains of 26 other large mammals, including a sabre-toothed tiger, 600 metres from the nearest sinkhole. Health & Science Girl's 12,000-year-old skeleton may solve a mystery Divers exploring the waters off of Mexico's eastern Yucatn Peninsula recently discovered a near-complete,. Now some of those bones have been recovered, and the latest fossil examinations are giving paleontologists crucial new insight into the Great American Interchange, a dizzying migration of ancient animals between North and South America. Her bones were part of a 2007 discovery of a cache of animal bones in an underwater chamber called Hoyo Negro (Spanish for "Black Hole") in the Sistema Sac Actun. There were 26 in total, some of which are extinct but others, like the puma and white-nosed coati, are still around today. Most scientists have assumed that the first humans to come to the Americas traveled from Eurasia across the Bering land bridge that existed before the oceans rose after the Ice Ages. Or perhaps she was following an animal. Poachers have taken notice. Because these drip water deposits formed on top of Naias bones, their date must occur after she fell in the cave.
Ancient bones reveal girl's tough life in early Americas These facial differences have prompted some researchers to argue that Native American tribes may belong to a separate lineage from the early Americans, perhaps the result of multiple migrations, not all from Beringia. Revelations made this past spring about her DNA make this 13,000-year-old girl (name Naia by those who discovered her) one of the most extraordinary archeological finds in Mexico.

Divers also found the skull of a stocky, coyote-like canid previously only known from South America. Ribs and a broken pelvis lay nearby. As the divers explored the vast chamber, they found that it was littered with the bones of now-extinct animals, including ground sloths and elephantlike creatures known as gomphotheres. The morphology of the later people is so different from the early ones that they dont appear to be part of the same population., He went on: Do they come from different parts of the world? She promises to reveal a lot about the physical characteristics of the earliest Americans. 344, no. Chatters acknowledged that much more work still has to be done. But his teams data, he points out, are consistent with the idea that Native Americans evolved from Siberian ancestors. ), At the paleontology meeting, Schubert revealed that bears also entered these cavesand, in the case of Hoyo Negro, sometimes never exited. It was a small cranium lying upside down with a perfect set of teeth and dark eye sockets looking back at us, Nava said.
