Secret History
In northwestern Africa, lifestyle transitioned from foraging to farming some 7,400 years ago, but what sparked that change remained unclear. Previous studies support conflicting views: that migrant European Neolithic farmers brought the new way of life to North Africa, or that local hunter-gatherers adopted farming practices.
"We found a remarkable population continuity up until seven and a half thousand years ago in northwestern Africa, where a group of local foragers had been living — isolated — for at least 8,000 years, perhaps since much further back in time," says Professor Mattias Jakobsson, Uppsala University, who led the study.

An Homo naledi group carry one of their dead into Rising Star cave in this artist's depiction. New evidence that these small-brained hominins may have practiced deliberate burial throws a curve into current thinking on human evolution.
The claims, made today in two research papers uploaded to the preprint server bioRxiv, were also announced by paleoanthropologist Lee Berger at a conference at Stony Brook University in New York.
The publications come eight years after Berger first reported the discovery of a new hominin species inside the Rising Star cave system 25 miles northwest of Johannesburg. Named Homo naledi, the species is characterized by its small size — including a brain roughly a third the size of today's humans — and a baffling mix of very old and relatively modern anatomical features.

A key component of the York project is the 3D scanning of the negative cavities in the gypsum casings.
For reasons archaeologists do not entirely understand, the Romans sometimes poured liquid gypsum - a mineral used in making various types of cement and plaster - over the clothed bodies of adults and children in lead or stone coffins before burying them.
As the gypsum hardened around the bodies and they then broke down, a negative cavity formed that preserved the original position and contours of the dead. The imprint of shrouds, clothing, and footwear also survives in the gypsum, providing precious evidence for perishable materials that rarely survive in Roman graves.
The research has been ongoing since 2004 by a team from Yamagata University, led by Professor Makato Sakai. Yamagata University has been conducting geoglyph distribution surveys using satellite imagery, aerial photography, airborne scanning LiDAR, and drone photography to investigate the vast area of the Nazca Pampa covering more than 390 km2.
The Nazca Lines are thought to have been made over centuries, starting around 100 BC by the Nazca people of modern-day Peru. They were first studied in detail in the 1940s, and by the time they were designated a UNESCO World Heritage Site in 1994, around 30 were identified. They're remarkably well-preserved considering their age, helped by the desert's dry climate and winds that sweep away the sand but are being obscured by floods and human activity.
Archaeologists discovered 142 new designs in the desert over the course of ten years by manually identifying them using aerial photography and on-site surveying. Then, in collaboration with IBM Japan researchers, they used machine learning to search the data for designs that had been missed in previous studies.

While this old parchment page may look like one out of a wizard’s spellbook, it’s actually what scholars believe to be the world’s oldest recorded stand-up comedy routine.
That is illustrative of where the story goes from there — a performance relevant to the humor enjoyed in Britain today, and one which colors the high Middle Ages as a time of artistic liberty, social mobility, and vigorous nightlife.
Heege's booklet contains three texts gleaned from the jester's material: a Hunting of the Hare story featuring a killer rabbit, a mock sermon in prose in which three kings eat so much that 24 bulls explode out of their stomachs and begin sword fighting, and an alliteration nonsense verse entitled The Battle of Brackonwet.
For a long time, some people held a skeptical attitude toward China's 5,000 years of civilization due to a lack of systematic data. Since its launch in 2001, the project to trace the origins of Chinese civilization has made significant achievements in restoring historical truth, countering skepticism, and presenting new evidence from archaeological excavations and scientific research.
The project has demonstrated how China developed its own unique path toward civilization through its unyielding determination and willpower. Studies have shown that around 5,800 years ago, the development in the complexity of prehistoric societies in the middle and lower reaches of the Yellow River and Yangtze River and the west of Liaohe River basin accelerated, showing signs of the origin of civilization. For example, the Hongshan Culture in the west of Liaohe River basin formed a ceremonial and sacrificial center with stone altars, temples, and tombs, showing clear social differentiation and a theocracy-dominated regional civilization.
Starting 5,300 years ago, various regions in ancient China successively formed early states and entered the first stages of civilization. For example, the Liangzhu culture was characterized by mature rice farming, large-scale construction projects, exquisite pottery, jade wares, ivory scepters and textiles. The vast area had common spiritual beliefs, economic forms and a unified society, which formed the centralized social structure and the initial form of a "monarchy state."
Ancient Egyptian texts don't mention any local sources, but an older view, derived from the presence of gold in silver objects, plus the high silver content of Egyptian gold and electrum, holds that silver was derived from local sources.
An alternative view is that silver was imported to Egypt, possibly via Byblos on the Lebanese coast, owing to many silver objects found in Byblos tombs from the late fourth millennium.

Japanese Unit 731 staff carrying a body from one of the unit's facilities.
The "horror bunker," discovered near the city of Anda in Heilongjiang province, northeast China, was used by the Japanese army's infamous Unit 731 during Japan's occupation of China from 1931 to 1945.
Built by the Japanese in 1941 and running until Japan's surrender at the end of World War II, the lab was Unit 731's largest research site, but its exact location was lost until now. Unit 731 began in 1931 as a Japanese-run public health unit, but it quickly expanded its research to include grotesque biological and chemical warfare experiments using Chinese, Korean, Russian and American captives as test subjects.

The newly found petroglyphs from Sweden include depictions of humans.
The petroglyphs were carved on a granite rock face that was once part of an island, meaning people would have had to make the carvings while standing on a boat, or from a platform constructed on ice, said Martin Östholm, a project manager with the Foundation for Documentation of Bohuslän's Rock Carvings who is one of the archaeologists who discovered the petroglyphs, told Live Science.

The petroglyphs are high up on a granite rock face that cannot be climbed, so researchers built a platform to study them.

A lightweight survey vehicle provides large-scale magnetic mapping of cultural traces hidden beneath the present-day tidal flat surface.
Using a combination of geoscientific and archaeological methods, researchers from Kiel University (CAU), Johannes Gutenberg University Mainz (JGU), the Center for Baltic and Scandinavian Archaeology (ZBSA), and the State Archaeology Department Schleswig-Holstein (ALSH), both in Schleswig, have now succeeded in locating the site of the Rungholt church. Thus, they can now finally clarify a much-discussed research question that has been going on for over 100 years.
