Published 'Time-traveling' pathogens in melting permafrost pose likely risk to environment
(via sciencedaily.com) Original source Ancient pathogens that escape from melting permafrost have real potential to damage microbial communities and might potentially threaten human health, according to a new study.
Published New insights into the origin of the Indo-European languages
(via sciencedaily.com) Original source An international team of linguists and geneticists has achieved a significant breakthrough in our understanding of the origins of Indo-European, a family of languages spoken by nearly half of the world's population.
Published Ancient DNA reveals diverse community in 'Lost City of the Incas'
(via sciencedaily.com) Original source DNA analysis of 34 individuals buried at Machu Picchu revealed that many traveled alone from throughout the Inca Empire.
Published Family trees from the European Neolithic
(via sciencedaily.com) Original source The Neolithic burial site of Gurgy 'les Noisats' in France revealed two unprecedentedly large family trees which allowed a Franco-German team to explore the social organization of the 6,700-year-old community. Based on multiple lines of evidence, the team describes a close kin group which practiced monogamy and female exogamy, and experienced generally stable times.
Published Missing island explains how endemic species on the Miyako Islands emerged
(via sciencedaily.com) Original source Miyako Islands are home to various native species of snake and lizards. How these species came to call these islands home has long puzzled scientists. A group of researchers have compiled the latest geological and biological data, proposing that an island once facilitated migration between Okinawa and Miyako Islands.
Published Picky green sea turtle has travelled to the same place to eat for generations
(via sciencedaily.com) Original source For approximately 3,000 years, generations of green sea turtles have returned to the same seagrass meadows to eat. The fact that this stretches over many generations highlights the importance of protecting seagrass meadows along the coasts of North Africa.
Published Hidden details of Egyptian paintings revealed by chemical imaging
(via sciencedaily.com) Original source Portable chemical imaging technology can reveal hidden details in ancient Egyptian paintings, according to new research.
Published Study examines centuries of identity lost because of slavery
(via sciencedaily.com) Original source Using computational methods informed by genetic data, researchers estimate that a random African American born between 1960 and 1965 is descended from, on average, 314 African and 51 European ancestors reaching back to 1619.
Published Giant stone artefacts found on rare Ice Age site in Kent, UK
(via sciencedaily.com) Original source Researchers have discovered some of the largest early prehistoric stone tools in Britain.
Published Lessons in sustainability, evolution and human adaptation -- courtesy of the Holocene
(via sciencedaily.com) Original source The El Gigante rockshelter in western Honduras is among only a handful of archaeological sites in the Americas that contain well-preserved botanical remains spanning the last 11,000 years. Considered one of the most important archaeological sites discovered in Central America in the last 40 years, El Gigante was recently nominated as a UNESCO World Heritage site.
Published Glass sponge genome furnishes insights into evolution of biomineralization
(via sciencedaily.com) Original source The genome of a glass sponge species suggests that silica skeletons evolved independently in several groups of sponges.
Published Cave excavation pushes back the clock on early human migration to Laos
(via sciencedaily.com) Original source Fifteen years of archaeological work in the Tam Pa Ling cave in northeastern Laos has yielded a reliable chronology of early human occupation of the site. The team's excavations through the layers of sediments and bones that gradually washed into the cave and were left untouched for tens of thousands of years reveals that humans lived in the area for at least 70,000 years -- and likely even longer.
Published Face of Anglo-Saxon teen VIP revealed with new evidence about her life
(via sciencedaily.com) Original source The face of a 16-year-old woman buried near Cambridge (UK) in the 7th century with an incredibly rare gold and garnet cross (the 'Trumpington Cross') has been reconstructed following analysis of her skull. The striking image is going on public display for the first time on 21st June, with new scientific evidence showing that she moved to England from Central Europe as a young girl, leading to an intriguing change in her diet.
Published Study shows ancient Alaskans were freshwater fishers
(via sciencedaily.com) Original source A scientific team has discovered the earliest-known evidence of freshwater fishing by ancient people in the Americas. The research offers a glimpse at how early humans used a changing landscape and could offer insight for modern people facing similar changes.
Published Fossil study sheds light on famous spirals found in nature
(via sciencedaily.com) Original source A 3D model of a 407-million-year-old plant fossil has overturned thinking on the evolution of leaves. The research has also led to fresh insights about spectacular patterns found in plants.
Published Climate change likely led to violence in early Andean populations
(via sciencedaily.com) Original source Climate change in current times has created problems for humans such as wildfires and reduced growing seasons for staple crops, spilling over into economic effects. Many researchers predict, and have observed in published literature, an increase in interpersonal violence and homicides when temperatures increase. Violence during climatic change has evidence in history, anthropology researchers say.
Published Remains at Crenshaw site are local, ancestors of Caddo
(via sciencedaily.com) Original source Hundreds of human skulls and mandibles recovered from the Crenshaw site in southwest Arkansas are the remains of ancestors of the Caddo Nation and not foreign enemies, according to a new study.
Published The Viking disease can be due to gene variants inherited from Neanderthals
(via sciencedaily.com) Original source Many men in northern Europe over the age of 60 suffer from the so-called Viking disease, which means that the fingers lock in a bent position. Now researchers have used data from over 7,000 affected individuals to look for genetic risk factors for the disease. The findings show that three of the strongest risk factors are inherited from Neanderthals.
