Published DNA from preserved feces reveals ancient Japanese gut environment
(via sciencedaily.com) Original source DNA from ancient feces can offer archaeologists new clues about the life and health of Japanese people who lived thousands of years ago, according to a new study.
Published Woolly mammoth movements tied to earliest Alaska hunting camps
(via sciencedaily.com) Original source Researchers have linked the travels of a 14,000-year-old woolly mammoth with the oldest known human settlements in Alaska, providing clues about the relationship between the iconic species and some of the earliest people to travel across the Bering Land Bridge. Isotopic data, along with DNA from other mammoths at the site and archaeological evidence, indicates that early Alaskans likely structured their settlements to overlap with areas where mammoths congregated. Those findings, highlighted in the new issue of the journal Science Advances, provide evidence that mammoths and early hunter-gatherers shared habitat in the region. The long-term predictable presence of woolly mammoths would have attracted humans to the area.
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 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 Mesopotamian bricks unveil the strength of Earth's ancient magnetic field
(via sciencedaily.com) Original source Ancient bricks inscribed with the names of Mesopotamian kings have yielded important insights into a mysterious anomaly in Earth's magnetic field 3,000 years ago, according to a new study.
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 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 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 Study of ancient British oral microbiomes reveals shift following Black Death
(via sciencedaily.com) Original source The Second Plague Pandemic of the mid-14th century, also known as the Black Death, killed 30-60 percent of the European population and profoundly changed the course of European history. New research suggests that this plague, potentially through resulting changes in diet and hygiene, may also be associated with a shift in the composition of the human oral microbiome toward one that contributes to chronic diseases in modern-day humans.
Published Neanderthals were the world's first artists, research reveals
(via sciencedaily.com) Original source Recent research has shown that engravings in a cave in La Roche-Cotard (France), which has been sealed for thousands of years, were actually made by Neanderthals. The findings reveal that the Neanderthals were the first humans with an appreciation of art.
Published 'Woman the hunter': Studies aim to correct history
(via sciencedaily.com) Original source New research combined both physiological and archaeological evidence to argue that not only did prehistoric women engage in the practice of hunting, but their female anatomy and biology would have made them intrinsically better suited for it.
Published Massive 2022 eruption reduced ozone layer levels
(via sciencedaily.com) Original source The Hunga Tonga-Hunga Ha'apai volcano changed the chemistry and dynamics of the stratosphere in the year following the eruption, leading to unprecedented losses in the ozone layer of up to 7% over large areas of the Southern Hemisphere.
Published Radiocarbon dating meets Egyptology and Biblical accounts in the city of Gezer
(via sciencedaily.com) Original source New dates provide detailed insights into the timing of events in the ancient city of Gezer, according to a new study.
Published Long-distance weaponry identified at the 31,000-year-old archaeological site of Maisières-Canal
(via sciencedaily.com) Original source The hunter-gatherers who settled on the banks of the Haine, a river in southern Belgium, 31,000 years ago were already using spearthrowers to hunt their game. The material found at the archaeological site of Maisières-Canal permits establishing the use of this hunting technique 10,000 years earlier than the oldest currently known preserved spearthrowers. This discovery is prompting archaeologists to reconsider the age of this important technological innovation.
Published Human emissions increased mercury in the atmosphere sevenfold
(via sciencedaily.com) Original source Researchers estimated that before humans started pumping mercury into the atmosphere, it contained on average about 580 megagrams of mercury. However, in 2015, independent research that looked at all available atmospheric measurements estimated the atmospheric mercury reservoir was about 4,000 Mg -- nearly 7 times larger than the natural condition estimated in this study.
Published Mystery of volcanic tsunami solved after 373 years
(via sciencedaily.com) Original source The explosion of the underwater volcano Kolumbo in the Aegean Sea in 1650 triggered a destructive tsunami that was described by historical eye witnesses. A group of researchers has now surveyed Kolumbo's underwater crater with modern imaging technology and reconstructed the historical events. They found that the eyewitness accounts of the natural disaster can only be described by a combination of a landslide followed by an explosive eruption.
Published In Prehispanic Cancun, immigrants were treated just like Maya locals
(via sciencedaily.com) Original source Ancient people immigrated to Cancun Island and were treated just like locals, according to a new study.
Published Climate change likely impacted human populations in the Neolithic and Bronze Age
(via sciencedaily.com) Original source Human populations in Neolithic Europe fluctuated with changing climates, according to a new study.
Published Challenging prehistoric gender roles: Research finds that women were hunters, too
(via sciencedaily.com) Original source Anthropologists challenge the traditional view of men as hunters and women as gatherers in prehistoric times. Their research reveals evidence of gender equality in roles and suggests that women were physically capable of hunting. The study sheds light on the gender bias in past research and calls for a more nuanced understanding of prehistoric gender roles.
