Published DNA study IDs descendants of George Washington from unmarked remains, findings to aid service member IDs going back to World War II (via sciencedaily.com) Original source
New DNA sequencing technologies have identified the historical remains of George Washington's grandnephews, Samuel Walter Washington and George Steptoe Washington Jr., and their mother, Lucy Payne Washington, from unmarked, fragmentary bones left at the Harewood family cemetery in Charles Town, West Virginia, in the mid-1800s.
Published Uncovering the mystery of Dorset's Cerne Giant (via sciencedaily.com) Original source
For centuries, the Cerne Giant, a figure carved into a hillside in Dorset, has fascinated locals and visitors to the area. A new paper proposes that the Cerne Giant can in fact be dated to the early Middle Ages, and, as a result, its cultural context and significance more clearly understood.
Published Persian plateau unveiled as crucial hub for early human migration out of Africa (via sciencedaily.com) Original source
A new study combining genetic, palaeoecological, and archaeological evidence has unveiled the Persian Plateau as a pivotal geographic location serving as a hub for Homo sapiens during the early stages of their migration out of Africa. It highlights the period between 70,000 to 45,000 years ago when human populations did not uniformly spread across Eurasia, leaving a gap in our understanding of their whereabouts during this time frame.
Published Tudor era horse cemetery in Westminster revealed as likely resting place for elite imported animals (via sciencedaily.com) Original source
Archaeological analysis of a near unique animal cemetery discovered in London nearly 30 years ago has revealed there was an international horse trading network, orchestrated by the elites of late medieval and Tudor England, which brought superior physical specimens to the UK for jousting and for use as status symbols.
Published Researchers name prehistoric amphibian ancestor discovered in Smithsonian collection after Kermit the Frog (via sciencedaily.com) Original source
Scientists have uncovered the fossilized skull of a 270-million-year-old ancient amphibian ancestor in the collection of the Smithsonian's National Museum of Natural History. The team of researchers described the fossil as a new species of proto-amphibian, which they named Kermitops gratus in honor of the iconic Muppet, Kermit the Frog.
Published Toba supereruption unveils new insights into early human migration (via sciencedaily.com) Original source
Working in the Horn of Africa, researchers have uncovered evidence showing how early modern humans survived in the wake of the eruption of Toba, one of the largest supervolcanoes in history, some 74,000 years ago. Modern humans dispersed from Africa multiple times, but the event that led to global expansion occurred less than 100,000 years ago. Some researchers hypothesize that dispersals were restricted to 'green corridors' formed during humid intervals when food was abundant and human populations expanded in lockstep with their environments. But a new study suggests that humans also may have dispersed during arid intervals along 'blue highways' created by seasonal rivers. Researchers also found evidence of cooking and stone tools that represent the oldest evidence of archery.
Published New archive of ancient human brains challenges misconceptions of soft tissue preservation (via sciencedaily.com) Original source
A new study has challenged previously held views that brain preservation in the archaeological record is extremely rare. The team compiled a new archive of preserved human brains, which highlighted that nervous tissues actually persist in much greater abundances than traditionally thought, assisted by conditions that prevent decay.
Published Across oceans and millennia: decoding the origin and history of the bottle gourd (via sciencedaily.com) Original source
Researchers have uncovered intriguing details about the origins and spread of the bottle gourd, one of the oldest domesticated crops. Their work unveils the genetic diversification and population history of this hard-shelled plant that was used to make bottles, instruments, and containers for over 10,000 years by ancient civilizations.
Published Modeling the origins of life: New evidence for an 'RNA World' (via sciencedaily.com) Original source
Scientists provide fresh insights on the origins of life, presenting compelling evidence supporting the 'RNA World' hypothesis. The study unveils an RNA enzyme that can make accurate copies of other functional RNA strands, while also allowing new variants of the molecule to emerge over time. These remarkable capabilities suggest the earliest forms of evolution may have occurred on a molecular scale in RNA, and also bring scientists one step closer to re-creating autonomous RNA-based life in the laboratory.
Published An evolutionary mystery 125 million years in the making (via sciencedaily.com) Original source
Plant biologists have uncovered an evolutionary mystery over 100 million years in the making. It turns out that sometime during the last 125 million years, tomatoes and Arabidopsis thaliana plants experienced an extreme genetic makeover. Just what happened remains unclear. But the mystery surrounds CLV3, a gene key to healthy plant growth and development.
Published Scientists ID burned bodies using technique used for extracting DNA from woolly mammoths, Neanderthals (via sciencedaily.com) Original source
A technique originally devised to extract DNA from woolly mammoths and other ancient archaeological specimens can be used to potentially identify badly burned human remains, according to research.
Published Climate change threatens thousands of archaeological sites in coastal Georgia (via sciencedaily.com) Original source
Thousands of historic and archaeological sites in Georgia are at risk from tropical storm surges, and that number will increase with climate change, according to a new study.
Published Experiment captures why pottery forms are culturally distinct (via sciencedaily.com) Original source
Potters of different cultural backgrounds learn new types differently, producing cultural differences even in the absence of differential cultural evolution. The research has implications for how we evaluate the difference of archaeological artifacts across cultures.
Published Plant seed and fruit analysis from the biblical home of Goliath sheds unprecedented light on Philistine ritual practices (via sciencedaily.com) Original source
While many aspects of Philistine culture are well-documented, the specifics of Philistine religious practices and deities have long remained shrouded in mystery. A recent study contributes valuable new data to our understanding of the Philistine's ritual practices. The discovery of numerous plants in two temples unearthed at the site unraveled unprecedented insights into Philistine cultic rituals and beliefs -- their temple food ingredients, timing of ceremonies, and plants for temple decoration.
Published Biggest Holocene volcano eruption found by seabed survey (via sciencedaily.com) Original source
A detailed survey of the volcanic underwater deposits around the Kikai caldera in Japan clarified the deposition mechanisms as well as the event's magnitude. As a result, the research team found that the event 7,300 years ago was the largest volcanic eruption in the Holocene by far.
Published Did neanderthals use glue? Researchers find evidence that sticks (via sciencedaily.com) Original source
Neanderthals created stone tools held together by a multi-component adhesive, a team of scientists has discovered. Its findings, which are the earliest evidence of a complex adhesive in Europe, suggest these predecessors to modern humans had a higher level of cognition and cultural development than previously thought.
Published Ancient DNA reveals Down syndrome in past human societies (via sciencedaily.com) Original source
By analysing ancient DNA, an international team of researchers have uncovered cases of chromosomal disorders, including what could be the first case of Edwards syndrome ever identified from prehistoric remains.
Published A lighthouse in the Gobi desert (via sciencedaily.com) Original source
A new study explores the weight great fossil sites have on our understanding of evolutionary relationships between fossil groups and quantified the power these sites have on our understanding of evolutionary history. Surprisingly, the authors discovered that the wind-swept sand deposits of the Late Cretaceous Gobi Desert's extraordinarily diverse and well-preserved fossil lizard record shapes our understanding of their evolutionary history more than any other site on the planet.
