Stone tools reflect three waves of migration of the earliest Sapiens into Europe

Lebanese and French artifacts from up to 54,000 years ago show shared cultural traditions revealing three phases of early human migrations in Europe

(Press-News.org) The first modern humans spread across Europe in three waves during the Paleolithic, according to a study published May 3, 2023 in the open-access journal PLOS ONE by Ludovic Slimak of the CNRS and University of Toulouse III, France.

The archaeological record of Paleolithic Europe leaves many open questions regarding the nature of the arrival of modern humans into the region and the nature of how these newcomers interacted with the resident Neanderthal populations. In this study, Slimak compared records of stone tool technology across western Eurasia to document the sequence of early human activity in the region.

This study primarily focused on comparative analysis of tens of thousands of stone tools from two sites: Ksar Akil in Lebanon and Grotte Mandrin in France, that recently revealed the earliest Sapiens migration in Europe dating to 54,000 years old. The study analyzed their precise technical connections with the earliest modern technologies in the continent. The author identifies a similar sequence of three technological phases in both regions, suggesting three distinct waves of migration of Homo sapiens across Europe.

These trans-Mediterranean technological connections allow for a reinterpretation of the pattern of human arrival in Europe and its precise relations with the Levantine region. Further examination of these apparent phases of human migration will establish a clearer picture of the sequence of events as Homo sapiens spread across the region and, in doing so, gradually replaced Neanderthals.

Slimak adds: “Until 2022, it was believed that Homo sapiens had reached Europe between the 42nd and 45th millennium. The study shows that this first Sapiens migration would actually be the last of three major migratory waves to the continent, profoundly rewriting what was thought to be known about the origin of Sapiens in Europe. Chatelperronian culture, one of the first modern traditions in western Europe and since then attributed to Neanderthals, should in fact signal the second wave of Homo sapiens migration in Europe, impacting deeply our understanding of the cultural organization of the last Neanderthals.”

Visitors to a modern art museum lingered in front of artworks longer and exhibited more signs of excitement when given detailed descriptions of each piece compared to seeing basic labels, according to a study published May 3, 2023 in the open-access journal PLOS ONE by Serena Castellotti from the University of Florence, Italy, and colleagues.  Improving the cultural and aesthetic experience of non-expert visitors is a critical task for art museums. In this study, the authors examined how museum-provided descriptions of art might influence a visitor’s ...

Bloodstream infections in preemies may originate from their gut microbiomes

2023-05-03
Dangerous bacterial bloodstream infections in preemies may originate from the infants’ gut microbiomes, according to researchers at Washington University School of Medicine in St. Louis. Such infections are of substantial concern, as about half of infants who are extremely preterm or have very low birth weights experience at least one episode of the life-threatening infection after 72 hours of life. The findings are published May 3 in the journal Science Translational Medicine. Preterm infants are at high risk of infections due to underdeveloped organs, coupled with considerable antimicrobial exposure. ...

Link to video and sound (details below): https://go.hawaii.edu/qRX Sweat is more than just a sign of a good workout. It holds vital information about our health, providing clues to dehydration, fatigue, blood sugar levels and even serious conditions such as cystic fibrosis, diabetes and heart failure. Researchers at the University of Hawaiʻi at Mānoa College of Engineering have taken a giant leap forward in sweat analysis with an innovative 3D-printed wearable sweat sensor called the “sweatainer.” Harnessing the power of additive manufacturing (3D-printing), the researchers have developed ...

Studying fundamentals of water as a solvent could lead to greener cellulose-based products

2023-05-03
Water isn’t just a universal solvent that remains unaffected by its interactions. New publications from North Carolina State University show that water can change its solubility characteristics depending upon what it interacts with. Specifically, when water interacts with cellulose, it can stack in layered shells to control chemical reactions within, and physical properties of, the material. The work has implications for more sustainable and efficient design of cellulose-based products. “Cellulose is the world’s most abundant biopolymer, and it’s used in applications ...

As the cosmetics industry continues to shift to more natural ingredients, some natural preservatives have been found to not be strong enough to withstand the conditions of large-scale manufacturing processes compared to chemical counterparts. One University of Cincinnati program is addressing the issue. “The manufacturing process is optimized to work with the current system, and as a result, when they are trying to make products with these new materials, we are ending up with an increased number of cases of microbiological ...

WASHINGTON, May 3, 2023 – This year and next, Americans will have the extraordinary opportunity to witness two solar eclipses as both will be visible throughout the continental U.S. On Oct. 14, 2023, the moon will obscure all but a small annulus of the sun, producing a “ring of fire” eclipse. On April 8, 2024, the eclipse will be total in a band stretching from Texas to Maine. Both occurrences promise to be remarkable events and teachable moments. But preparation is essential.
