Argentina Returns Artifacts to Peru
LIMA, PERU—Andina, Peru’s news agency, reports that more than 4,000 artifacts recovered in Argentina were returned to Peru last week, when the two countries signed an Agreement for the Protection, Conservation, Recovery and Return of Stolen or Illegally Exported or Transferred Cultural, Archaeological, Artistic and Historical Property. Most of the objects were seized by the government of Argentina from art collectors and traffickers in 2000. The artifacts cover a range of historic periods and include items made from metal, textiles, wood, pottery, organic fibers, and human remains. This is the largest group of artifacts repatriated to Peru to date. To read more about archaeology in Peru, go to "A Wari Matriarchy?"
Britain’s “Lost” Roman Roads Found With Lidar
LONDON, ENGLAND—Archaeologists have used Lidar images produced by Britain’s Environment Agency for flood modeling and monitoring coastlines to look for roads that the Romans built in the first century during the conquest of northern England. David Ratledge has been looking for Roman roads in Lancashire for the past 45 years. Using Lidar data, he’s found a road that stretches from Ribchester to Lancaster, a distance of more than ten miles. “Previously in Lancashire we only had aerial photographs from the 1940s and 1960s to go on, but with photographs features only show up after a drought and we don’t get many of those! With Lidar, once you know what to look for, it’s blindingly obvious—you just know you’ve found a road,” he said in a press release. Four more Roman roads have been found by Hugh Toller and Bryn Gethin, including a missing part of the “Maiden Way” in Cumbria that connects the fort at Low Borrowbridge to a cavalry camp at Kirkby Thore, before it continues on to Whitely Castle and Carvoran Roman Fort, near Hadrian’s Wall in Northumbria. “These were the county’s most important Roman sites so good communications between them must have been essential,” said Ratledge.

Roman Pottery Examined With High-Tech Tools
FAYETTEVILLE, ARKANSAS—Rachel Opitz of the University of Arkansas’ Center for Advanced Spatial Technologies (CAST) is working with Rome’s Capitoline Museum and the University of Missouri to study ancient ceramics of unknown provenance. The objects, which range in age from 2,000 to 2,400 years old, have been stored at the museum for more than a century. Neutron activation analysis at the Missouri University Research Reactor will help scholars identify the clay in the ceramic vessels and perhaps pinpoint where they originated. Opitz was called in by the team to scan the vessels with high-resolution structured-light technology. The 3-D images can show traces of wear that are invisible to the naked eye and distinguish between marks made from regular usage in the past and more recent scratches. “The production of a bowl or plate is interesting, but how it is used day to day, how it is lifted, washed, cooked in, chipped, and eventually thrown out is just as important,” Opitz said in a press release.

Maori Storage Pits Point to Large Settlement
TAURANGA, NEW ZEALAND—A road-widening project has uncovered more than 20 food storage pits and a pataka, or food storage building, on the Otumoetai peninsula of New Zealand’s North Island. Their size suggest that there was a large Maori settlement in the area between 200 and 400 years ago. “Kumara pits similar to those found on Maxwells Road are apparently found quite frequently in the Bay of Plenty, however we understand none have been found in the area of Tauranga to date,” Marcel Currin, Tauranga City Council communications adviser, told the Bay of Plenty Times. “Artifacts including obsidian (volcanic glass) and fragments of stone adzes have been found in the area,” he added.

Early Christian Church Discovered in Cappadocia
NEVŞEHIR, TURKEY—Excavation of an ancient underground city in Turkey’s Cappadocia region has revealed a Christian church that could date to the fifth century A.D. “This place is even bigger than the other historical churches in Cappadocia. It was built underground and has original frescoes that have survived to this day,” the mayor of Nevşehir, Hasan Ünver, told Hürriyet Daily News. Archaeologists say that the church walls collapsed, but they will be slowly dried out and restored. “We have stopped work in order to protect the wall paintings and the church. When the weather gets warmer in the spring, we will wait for humidity to evaporate and then we will start removing the earth,” said archaeologist Ali Aydin. Some of the paintings uncovered so far are said to be unique. “There are exciting depictions like fish falling from the hand of Jesus Christ, him rising up into the sky, and the bad souls being killed. When the church is completely revealed, Cappadocia could become an even bigger pilgrimage center of Orthodoxy,” the mayor added.

Viking Adaptation Predisposes Descendants to Disease
LIVERPOOL, ENGLAND—An inherited deficiency in alpha-1-antitrypsin (A1AT) can contribute to the onset of the debilitating illnesses of chronic obstructive pulmonary disease (COPD) and emphysema. A1AT protects the lungs and liver from enzymes produced by the immune system, but those enzymes, called proteases, are also produced by parasitic worms. Richard Pleass of the Liverpool School of Tropical Medicine and a team of scientists say that deviant forms of A1AT evolved in Viking populations more than 2,000 years ago to combat worm infestations. “Vikings would have eaten contaminated food and parasites would have migrated to various organs, including lungs and liver, where the proteases they released would cause disease,” he said in a press release. “Thus these deviant forms of A1AT would have protected Viking populations, who neither smoked tobacco nor lived long lives, from worms. It is only in the last century that modern medicine has allowed human populations to be treated for disease-causing worms. Consequently these deviant forms of A1AT, that once protected people from parasites, are now at liberty to cause emphysema and COPD,” he explained.

Europe’s First Modern Humans May Have Been Replaced
TÜBINGEN, GERMANY—A new genetic study suggests that some 50,000 years ago, all non-Africans dispersed rapidly from a single population, and that around 14,500 years ago, there was a major turnover of the population in Europe. Researchers reconstructed the mitochondrial genomes of 35 hunter-gatherers who lived in Italy, Germany, Belgium, France, the Czech Republic, and Romania between 35,000 and 7,000 years ago. The mitochondrial DNA of three of these individuals, who lived in what is now Belgium and France more than 25,000 years ago, belonged to haplogroup M. Haplogroup M is now very common in Asian, Australasian, and Native American populations, but had not been found in Europe, leading to the argument for multiple migrations. “When the Last Glacial Maximum began around 25,000 years ago, hunter-gatherer populations retreated south to a number of putative refugia, and the consequent genetic bottleneck probably resulted in the loss of this haplogroup,” Cosimo Posth of the University of Tübingen said in a press release. The DNA study also indicates that those who survived the cold of the Last Glacial Maximum were replaced by a population from another source.

New Research Resets the Molecular Clock
NEW YORK CITY, NEW YORK—The rate at which mutations occur helps evolutionary geneticists estimate when events such as the split between the ancestors of humans and chimpanzees occurred. New estimates of the mutation rate, however, put the split between humans and chimpanzees at odds with the fossil record. Scientists at Columbia University have produced a new model, described in a press release, that takes life history traits, such as puberty and reproduction, into account for the number of mutations that are passed on to offspring. Since these life history traits evolve, the mutation rate should evolve as well. Based upon this model, the rate of mutation has slowed down, and the split between humans and other apes may have occurred as recently as 6.6 million years ago.

Cultural Competition May Account for Neanderthal Extinction
STANFORD, CALIFORNIA—Phys.org reports that William Gilpin and Marcus Feldman of Stanford University and Kenichi Aoki of Meiji University adapted a computer model that was developed to mimic interspecies competition to investigate the interaction between modern humans and Neanderthals in Europe some 45,000 years ago. The model took cultural and technical abilities into consideration, and, as the researchers wrote in the Proceedings of the National Academy of Sciences, the results suggest that a group that was culturally more advanced may have been able to displace a group that was culturally less advanced, even if that group was initially much larger. In theory, modern humans would have been able to use their cultural and technological advantages to outcompete Neanderthals for natural resources. The researchers add that it is not clear why Neanderthals did not copy the successful culture and technology. To read more about our extinct cousins, go to "Should We Clone Neanderthals?"
3,500-Year-Old Egyptian Seal Discovered in Israel
KARNEI HATTIN, ISRAEL—A hiker discovered a 3,500-year-old Egyptian seal in the Lower Galilee on the Horns of Hattin, so-called for the twin peaks of an extinct volcano where a fortified citadel stood in the late Bronze Age. Recent rainstorms may have brought the artifact to the surface. The man handed the seal, carved in the shape of a beetle, over to the Israel Antiquities Authority. “The scarab represents Pharaoh Thutmose III (1481-1425 B.C.) sitting on his throne, and before him is a cartouche—an oval shape that contains symbols representing his name in hieroglyphics,” curator of Egyptian archaeology at the Israel museum Daphna Ben-Tor told Haaretz. “Thutmose ruled for many years during the fifteenth century B.C., and during his reign Egypt set up an administrative system of governance in Canaan. There, he waged many campaigns of conquest, of which the most famous was the battle of Megiddo in the Jezreel Valley—a victory documented in giant tablets on the walls of the Karnak Temple in [Luxor}, Egypt,” she explained.
