YINCHUAN, CHINA—Nine sections of the Great Wall have been found along the border of northwest China’s Ningxia Hui Autonomous Region and Gansu Province. “Finally, we’re able to see the whole picture of the Qin Great Wall,” Zhou Xinghua, a former curator of the Museum of Ningxia Hui Autonomous Region told China Daily. Six of the sections are on the southern bank of the Yellow River, and stretch between Nanchangtan Village in Ningxia and Jingyuan County in Gansu. The wall would have prevented invaders from crossing the river when it was frozen. The other three sections are in Jingyuan County.

BOULDER, COLORADO—Bronze and obsidian artifacts discovered in a dwelling at Alaska’s Rising Whale site bolster the idea that there had been a trading relationship between the New World and East Asia 1,000 years ago. One of the bronze artifacts, which may have been used as a buckle or fastener, still has a piece of leather attached to it. Preliminary radiocarbon dates indicate that it was made around A.D. 600. The second bronze artifact may have been used as a whistle. Bronze had not yet been developed in Alaska, so the items may have been obtained through trade. “We’re seeing the interactions, indirect as they are, with these so-called ‘high civilizations’ of China, Korea, or Yakutia,” Owen Mason of the University of Colorado told Live Science. The obsidian from the house originated in Russia’s Anadyr River Valley. Scholars think that the people who lived at the Rising Whale site may have been members of the “Birnirk” culture, a group of people who lived on both sides of the Bering Strait.

SAN FRANCISCO, CALIFORNIA—The National Oceanic and Atmospheric Administration (NOAA), the U.S. Navy, and private industry partners have confirmed the location and condition of the USS Independence, a light aircraft carrier that operated in the central and western Pacific from November 1943 through August 1945. The ship was later one of 90 vessels that served as a target fleet for the Bikini Atoll atomic bomb tests in 1946, when it was damaged by shock waves, heat, and radiation from two atomic blasts. Independence then returned to the United States, where it was used by the Navy to study decontamination until it was towed off the coast of California in 1951 and scuttled in 3,000 feet of water. “After 64 years on the seafloor, Independence sits on the bottom as if ready to launch its planes,” James Delgado, maritime heritage director for NOAA’s Office of National Marine Sanctuaries, said in a press release. The survey of the ship determined that it is upright, slightly listing to starboard, and much of its flight deck is intact. There are gaping holes leading to the hangar decks that once housed the carrier’s aircraft. To read more about underwater archaeology, see "History's 10 Greatest Shipwrecks."
EXETER, ENGLAND—Archaeology students at the University of Exeter learned to make stone tools in the Oldowan and Acheulean traditions over an 18-month period, in order to evaluate the cognitive control required to make them successfully. At the beginning, middle, and end of the experiment, they underwent functional magnetic resonance imaging (fMRI) and diffusion tensor imaging (DTI) scans of their brains while they watched videos and were asked questions about tool making. “For the first time, we’ve showed a relationship between the degree of prefrontal brain activity, the ability to make technological judgments, and success in actually making stone tools,” Dietrich Stout of Emory University said in a press release on Phys.org. Oldowan flakes, which date back 2.6 million years, are relatively easy to make, and the students were asked to detach five flakes from a flint core. Late Acheulean hand axes are about 500,000 years old and require the knapper to produce a tool with symmetrical edges from a lens-shaped core. The subjects were give a standardized porcelain core to work with for this task. The researchers, including Bruce Bradley of the University of Exeter, Thierry Chaminade of Aix-Marseille University, and Erin Hecht and Nada Khreisheh of Emory University, found that students who demonstrated greater skill at making tools were more accurate at predicting the correct strategy for making a hand ax while watching the instructional videos. “These data suggest that making an Acheulean hand ax is not simply a rote, auto pilot activity of the brain. It requires you to engage in some complicated thinking,” Stout said. He adds that the modern axes “weren’t up to the high standards of 500,000 years ago.” To read about one of the most significant Acheulean hand ax discoveries of recent times, see "Bon Voyage, Caveman."
BRADFORD, ENGLAND—Julia Beaumont of the University of Bradford and a team of scientists have analyzed the carbon and nitrogen isotopes in the teeth of children and adults who died during the 1845-52 Irish famine. Teeth, which begin to grow before birth, are formed in layers. Each layer of a tooth takes about four months to grow and can be linked to a specific period in a baby’s life. Higher nitrogen levels in bones and teeth are usually associated with good health and a high-protein diet, but the study showed that the babies who had higher nitrogen isotope levels at birth didn’t survive. In fact, older subjects had lower and more stable nitrogen isotope levels throughout early childhood. “At the period we studied, it’s likely that most babies were breastfed, but only some showed the spike in nitrogen isotope levels normally associated with it. Where pregnant and breastfeeding mothers are malnourished however, they can recycle their own tissues in order for the baby to grow and then to produce milk to feed it. We believe this produces higher nitrogen isotope levels and is what we’re seeing in the samples from the nineteenth-century cemeteries. Babies born to and breastfed by malnourished mothers do not receive all the nutrients they need, and this is possibly why these babies didn’t survive,” Beaumont said in a press release.

HARYANA, INDIA—Four 5,000-year-old skeletons from the Harappan civilization have been recovered from an ancient cemetery near Rakhigarhi village in northern India. The well-preserved skeletons were discovered in sandy soil, and the joint team of scientists from Deccan College, the Haryana Archaeology Department, and Seoul National University in South Korea will attempt to collect DNA samples from the bones. “The skeletons of two adult males, a female, and a child have been found. With the help of forensic experts, we will try to reconstruct their DNA,” Nilesh Jadhav, co-director of the project, told The Tribune of India. The results could shed light on the identity of the Harappan people. To read about a related civilization in what is now Iran, see "The World In Between."
SAN FRANCISCO, CALIFORNIA—At the annual meeting of the Paleoanthropology Society, Sonia Harmand of Stony Brook University announced the discovery of 3.3 million-year-old tools at the site of Lomekwi 3. In 2011, her team was traveling west of Kenya’s Lake Turkana, near the area where a controversial human relative called Kenyanthropus platyops had been discovered, when they saw stone tools on the surface of the ground. Excavation uncovered nearly 20 anvils, cores, and flakes, including a flake that fits into its original core. “The artifacts were clearly knapped and not the result of accidental fracture of rocks,” Harmand said at the meeting, reported in Science. All of the artifacts, which have their own distinct style, were sealed in sediments that were dated using paleomagnetic techniques. Until now, 2.6-million-year-old Oldowan tools from the site of Gona in Ethiopia were the oldest tools on record. The tools from Lomekwi 3 are too old to have been made by modern humans, and may have been created by australopithecines or by Kenyanthropus.

IOWA CITY, IOWA—Scientists have debated for more than a century why modern humans are the only primates to sport chins. Young modern human children have nearly imperceptible chins, similar to Neanderthals, but they grow chins as they mature. Nathan Holton and colleagues at the University of Iowa measured the faces and crania of nearly 40 people, ranging in age from toddler to adult, and found that mechanical forces such as chewing do not produce enough resistance for new bone to be created in the lower jaw. “In short, we do not find any evidence that chins are tied to mechanical function and in some cases we find that chins are worse at resisting mechanical forces as we grow,” Holton said. Team member Robert Franciscus, an anthropologist, suggests that as modern humans formed increasingly cooperative groups, and were less likely to fight over territory and belongings, reduced levels of hormones such as testosterone resulted in noticeable changes in the male craniofacial region—as the face became smaller, the chin became a bony prominence as a matter of geometry. “What we’re arguing is that modern humans had an advantage at some point to have a well-connected social network, they can exchange information, and mates, more readily, there’s innovation, and for that to happen, males have to tolerate each other. There had to be more curiosity and inquisitiveness than aggression, and the evidence of that lies in facial architecture,” Franciscus explained.

ESSEX, ENGLAND—It had been thought that the nomadic hunter-gatherers of Britain’s Mesolithic period may have abandoned their dead, but a deposit containing cremated human bone was uncovered by a team from Oxford Archaeology in southeastern England. The bone probably represents at least one adult, whose remains were recovered with a large amount of charcoal, perhaps from a pyre that would have had to have reached a high temperature to achieve the complete combustion of the corpse. “We were expecting this cremation to date to the Bronze Age: we were so surprised when the first radiocarbon date came back as Mesolithic that we did two more to double check!” said Nick Gilmour, excavation leader. Sharp flint blades were found in the same pit, and although they were not finished tools, they could have been used for cutting. Three similar Mesolithic cremations are known in Ireland, and several have been found in continental Europe. For another find dating to this period, see "Beachcombing in the Mesolithic."
LEICESTER, ENGLAND—Mary Ann Lund of the University of Leicester thinks that Richard III may have kept his scoliosis hidden from public view, since no mention of it is known to have been made during his lifetime. “It is highly likely that Richard took care to control his public image. The body of the king was part of the propaganda of power, and even when it was revealed in order to be anointed as part of his coronation ceremony it was simultaneously concealed from the congregation,” she said in a press release. Lund suggests that tailoring kept his condition hidden from those outside the royal household until his corpse was stripped in front of witnesses after the Battle of Bosworth in 1485. Under the Tudor regime, the memory of Richard’s body became more misshapen, and included a withered arm and unequal limbs. “Stage history has reincarnated Richard as monster, villain and clown, but recent events have helped us to re-evaluate these physically defined depictions and strip back the cultural accretions that have surrounded his body,” she said.

MADRID, SPAIN—A new study of 57,600-year-old fossils from the Marillac site in France suggests that Neanderthals beat and fractured the bones of the recently deceased. The bones in the study, including leg and arm bones from two adults and a child, were found among the many bones of Neanderthals, animals, and tools at the site. The bones show cut marks made with flint tools while the bones were still fresh. No signs of carnivores’ teeth were found on these specimens, although signs of gnawing by animals have been found on other bones from the Marillac site. “To date we have been able to demonstrate these manipulations at several Neanderthal sites in Europe, which are of course much more recent, including groups of contemporary humans, but we have not been able to demonstrate the consumption of human meat by Neanderthals (although this has indeed been done in other much more modern populations),” María Dolores Garralda of Complutense University and the University of Bordeaux said in a Plataforma SINC press release. Why Neanderthals manipulated the bones in this way is uncertain. “There might have been rituals—still in the twenty-first century these continue in certain parts of the world—or for food—gastronomic cannibalism or due to need,” Garralda said. Many of the bones from the Marillac site still need to be analyzed. To read more about our extinct cousins, see "Should We Clone Neanderthals?"
CAIRO, EGYPT—Egypt’s Antiquities Minister Mamdouh el-Damaty announced that carved basalt blocks and part of a statue carved with the cartouche of King Merineptah were found by a joint Egyptian-German team of archaeologists. The chapel belonged to King Nectanebo I of the 30th Dynasty, the last royal family to rule before Egypt was conquered by Alexander the Great in 332 B.C. “Historical evidence suggests the pharaoh came to power by overthrowing Nepherites II, his predecessor and the last pharaoh of the 29th Dynasty,” archaeologist Sherif el-Sabban told The Cairo Post. The statue of Merineptah depicts the 19th-Dynasty pharaoh presenting an offering to a deity. The chapel was found within Heliopolis Temple, beneath modern Cairo. Ancient Heliopolis was one of the oldest cities in Egypt; most of its buildings were dismantled to build Cairo. Ground water has to be removed from the site for the excavation to continue.
