Published Discovery of immense fortifications dating back 4,000 years in north-western Arabia (via sciencedaily.com) Original source
The North Arabian Desert oases were inhabited by sedentary populations in the 4th and 3rd millennia BCE. A fortification enclosing the Khaybar Oasis -- one of the longest known going back to this period -- was just revealed by a team of scientists. This new walled oasis is, along with that of Tayma, one of the two largest in Saudi Arabia.
Published Study on lamprey embryos sheds light on the evolutionary origin of vertebrate head (via sciencedaily.com) Original source
Scientists have investigated lamprey embryos using cutting-edge microscopic techniques to reveal interesting insights about vertebrate head evolution, clarifying an unresolved mystery in basic science.
Published The extinction of the giant ape: Long-standing mystery solved (via sciencedaily.com) Original source
The largest ever primate Gigantopithecus blacki went extinct when other Asian great apes were thriving, and its demise has long been a mystery. A massive regional study of 22 caves in southern China explores a species on the brink of extinction between 295,000 and 215,000 years ago. As the environment became more seasonal, forest plant communities changed Primates such as orangutans adapted their eating habits and behaviors in response but G. blacki showed signs of stress, struggled to adapt and their numbers dwindled.
Published Cult mentality: Monumental discovery in Italy (via sciencedaily.com) Original source
Researchers have discovered an ancient Roman temple that adds significant insights into the social change from pagan gods to Christianity within the Roman Empire.
Published Early primates likely lived in pairs (via sciencedaily.com) Original source
Primate social organization is more flexible than previously assumed. According to a new study, the first primates probably lived in pairs, while only around 15 percent of individuals were solitary.
Published Western Cascades landscapes in Oregon historically burned more often than previously thought (via sciencedaily.com) Original source
Forests on the west slope of Oregon's Cascade Range experienced fire much more often between 1500 and 1895 than had been previously thought.
Published First high mountain settlers at the start of the Neolithic already engaged in other livestock activities apart from transhumance (via sciencedaily.com) Original source
An archaeological find in the Huescan Pyrenees allowed researchers to identify for the first time livestock management strategies and feeding practices which demonstrate how the first high mountain societies, at the start of the Neolithic period, were already carrying out complex livestock and farming activities, instead of being limited to the transhumance of sheep and goats.
Published Rise of archery in Andes Mountains dated to 5,000 years ago -- earlier than previous research (via sciencedaily.com) Original source
Focusing on the Lake Titicaca Basin in the Andes mountains, anthropologists found through analysis of 1,179 projectile points that the rise of archery technology dates to around 5,000 years ago. Previous research held that archery in the Andes emerged around 3,000 years ago. The new research from UC Davis indicates that the adoption of bow-and-arrow technology coincided with both the expansion of exchange networks and the growing tendency for people to reside in villages.
Published Researchers, Coast Salish people analyze 160-year-old indigenous dog pelt in the Smithsonian's collection (via sciencedaily.com) Original source
A new analysis sheds light on the ancestry and genetics of woolly dogs, a now extinct breed of dog that was a fixture of Indigenous Coast Salish communities in the Pacific Northwest for millennia. Anthropologists and biologists analyzed genetic clues preserved in the pelt of 'Mutton,' the only known woolly dog fleece in the world, to pinpoint the genes responsible for their highly sought-after woolly fur. The study's findings include interviews contributed by several Coast Salish co-authors, including Elders, Knowledge Keepers and Master Weavers, who provided crucial context about the role woolly dogs played in Coast Salish society.
Published AI provides more accurate analysis of prehistoric and modern animals, painting picture of ancient world (via sciencedaily.com) Original source
A new study of the remains of prehistoric and modern African antelopes found that AI technology accurately identified animals more than 90% of the time compared to humans, who had much lower accuracy rates depending on the expert.
Published 'A ticking clock': First ground-based survey of damage to Ukrainian cultural sites reveals severity, need for urgency (via sciencedaily.com) Original source
And after nearly two years of fighting, war is destroying Ukraine’s cultural heritage on a scale not seen since World War II, according to new research.
Published Cell types in the eye have ancient evolutionary origins (via sciencedaily.com) Original source
In a comparative analysis across vertebrates of the many cell types in the retina -- mice alone have 130 types -- researchers concluded that most cell types have an ancient evolutionary history. Their remarkable conservation across species suggests that the retina of the last common ancestor of all mammals, which roamed the earth some 200 million year ago, must have had a complexity rivaling the retina of modern mammals.
Published Archaeologists unearth one of earliest known frame saddles (via sciencedaily.com) Original source
Recovered from looters, a new archaeological discovery from a cave in western Mongolia could change the story of the evolving relationship between humans and horses around the world.
Published Molecular fossils shed light on ancient life (via sciencedaily.com) Original source
Paleontologists are getting a glimpse at life over a billion years in the past based on chemical traces in ancient rocks and the genetics of living animals. New research combines geology and genetics, showing how changes in the early Earth prompted a shift in how animals eat.
Published Ancient DNA analysis reveals how the rise and fall of the Roman Empire shifted populations in the Balkans (via sciencedaily.com) Original source
Despite the Roman Empire's extensive military and cultural influence on the nearby Balkan peninsula, a DNA analysis of individuals who lived in the region between 1 and 1000 CE found no genetic evidence of Iron Age Italian ancestry. Instead, a new study has revealed successive waves of migrations from Western Anatolia, central and northern Europe, and the Pontic-Kazakh Steppe during the Empire's reign.
Published Baboons in captivity in Ancient Egypt: insights from collection of mummies (via sciencedaily.com) Original source
Baboons were raised in captivity before being mummified in Ancient Egyptian sites, according to a new study.
Published Aging societies more vulnerable to collapse (via sciencedaily.com) Original source
Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies. A new study, which holds implications for the modern world, provides the first quantitative support for the theory that the resilience of political states decreases over time.
Published 'Bone biographies' reveal lives of medieval England's common people -- and illuminate early benefits system (via sciencedaily.com) Original source
Researchers give medieval Cambridge residents the 'Richard III treatment' to reveal hard-knock lives of those in the city during its famous university's early years. Study of over 400 remains from a hospital cemetery shows spectrum of medieval poverty, and suggests that some of Cambridge University's earliest scholars ended up in penury.
Published Paleolithic humans may have understood the properties of rocks for making stone tools (via sciencedaily.com) Original source
Research suggests that Paleolithic humans in the Middle East selected flint for their cutting tools based on differences in the mechanical properties of the rock. They seem to have purposefully selected the most suitable rocks for fashioning into tools, even being able to distinguish rocks that were unsuitable.
Published A mixed origin made maize successful (via sciencedaily.com) Original source
Maize is one of the world's most widely grown crops. It is used for both human and animal foods and holds great cultural significance, especially for indigenous peoples in the Americas. Yet despite its importance, the origins of the grain have been hotly debated for more than a century. Now new research shows that all modern maize descends from a hybrid created just over 5000 years ago in central Mexico, thousands of years after the plant was first domesticated.
