Prehistoric people occupied upland regions of inland Spain in even the coldest periods of the last Ice Age

15,000-21,000 years ago, inland Iberia may have been more populated than traditionally thought

Prehistoric people occupied upland regions of inland Spain in even the coldest periods of the last Ice Age
2023-10-04
(Press-News.org) Paleolithic human populations survived even in the coldest and driest upland parts of Spain, according to a study published October 4, 2023 in the open-access journal PLOS ONE by Manuel Alcaraz-Castaño of the University of Alcalá, Spain, Javier Aragoncillo-del Rió of the Molina-Alto Tajo UNESCO Global Geopark, Spain and colleagues.

Research into ancient hunter-gatherer populations of the Iberian Peninsula has mainly focused on coastal regions, with relatively little investigation into the inland. A classic hypothesis has been that the cold and dry conditions of inland Iberia would have been too harsh for such populations to inhabit during the coldest periods of the Last Glacial, but recent findings have begun to challenge this view. In this study, researchers report new evidence for high-altitude human occupation from the Upper Paleolithic of Spain.

This evidence comes from a site called Charco Verde II, located in the Guadalajara province. This site is situated over 1,000 meters above sea level, in one of the coldest regions of Spain. Despite this, the abundance of tools and ornaments at the site reveals a recurring sequence of human occupation between around 21,000 and 15,000 years ago. This time span is especially notable since it includes two of the coldest periods of the Last Glacial.

This discovery further challenges the idea that Upper Palaeolithic humans avoided inland Iberia due to its harsh climate, and instead shows that the inland hosted complex and relatively dense settlements even during very cold and arid periods. These findings add to the growing evidence for Middle and Upper Paleolithic occupations throughout this region, altogether indicating that the historic lack of evidence for hunter-gatherer sites in inland Iberia is not an accurate reflection of prehistoric human distributions, but instead a result of modern research hitherto prioritizing study of coastal regions and neglecting the inland.

Adoption of vegan dog and cat diets could have environmental benefits

Adoption of vegan dog and cat diets could have environmental benefits
2023-10-04
A new analysis estimates a variety of potential benefits for environmental sustainability—for instance, reduced freshwater consumption and greenhouse gas emissions—that could result from switching all pet dogs and cats in the US or around the world to nutritionally sound, vegan diets. Andrew Knight of Griffith University, Australia, presents these calculations in the open-access journal PLOS ONE on October 4, 2023. The livestock industry has environmental impacts, such as land and freshwater ...

Hospital superbugs: Could one vaccine rule them all?

2023-10-04
What if a vaccine, given to patients just before or after arriving at the hospital, could protect them against lethal superbugs that lurk in healthcare settings? That’s the premise behind an experimental vaccine invented by a USC-led team and patented by the university. Researchers designed the formula to prevent serious infections from drug-resistant pathogens. A new study shows that a single dose, administered in mouse models, put immune cells into "Incredible Hulk" mode, providing rapid protection against eight different bacteria and fungi species. “It’s an early warning system. ...

Analysis of grinding tools reveals plant, pigment and bone processing in Neolithic Northern Saudi Arabia

Analysis of grinding tools reveals plant, pigment and bone processing in Neolithic Northern Saudi Arabia
2023-10-04
In recent years, studies have revealed that the now-arid region of northern Arabia was once much wetter and greener, providing Neolithic human populations with access to both water and game. The present aridity of the region, however, preserves little organic matter, making a reconstruction of the Neolithic lifestyle difficult. Now, in a new study published in the journal PLOS ONE, researchers from the Max Planck Institute of Geoanthropology, the National Research Council of Italy, Institute of Heritage Science (CNR ISPC), and University College London present use-wear ...

Early human migrants followed lush corridor-route out of Africa

Early human migrants followed lush corridor-route out of Africa
2023-10-04
An international team of scientists has found early human migrants left Africa for Eurasia, across the Sinai peninsula and on through Jordan, over 80-thousand years ago. Researchers from the University of Southampton (UK) and Shantou University (China), together with colleagues in Jordan, Australia and the Czech Republic(1), have proved there was a “well-watered corridor” which funnelled hunter-gatherers through The Levant towards western Asia and northern Arabia via Jordan. Their findings, published in the journal Science Advances, support previous research conducted ...

A UCLA-led team may have found the key to stimulating human brown adipose tissue into combating obesity

2023-10-04
EMBARGOED FOR USE UNTIL: 2 p.m. (ET) on Oct. 4, 2023 -- A UCLA-led team of researchers has found nerve pathways that supply brown adipose tissue (BAT), a type of tissue that releases chemical energy from fat metabolism as heat – a finding that could pave the way toward using it to treat obesity and related metabolic conditions. The researchers have for the first time detailed this nerve supply and provided examples of how manipulating it can change BAT activity, marking a first step toward understanding how to use it therapeutically, said ...

Proteins roll the dice to determine bee sex

Proteins roll the dice to determine bee sex
2023-10-04
To date it has been unclear exactly how the sex of a bee is determined. A research team from Heinrich Heine University Düsseldorf (HHU) comprising biologists and chemists has now identified a key gene and the molecular mechanism linked with it. In the current issue of the scientific journal Science Advances, they describe how this process is similar to a game involving two dice. The sex of a living creature has significant consequences for its form, function and behaviour. The biological sex of an organism is usually determined at the start of its life. In humans, for example, the presence of the sex-determining “Y chromosome” ...
