Discover How Neanderthals Hunted Turtles for Tools, Not Meals

Recent research from Germany reveals that Neanderthals captured the European pond turtle (Emys orbicularis) approximately 125,000 years ago, likely valuing its shell as a tool more than its modest meat yield.

Professor Sabine Gaudzinski-Windhauser of MONREPOS and Johannes Gutenberg University Mainz stated, “Recent findings on Neanderthal prey selection reveal a fascinating overlap with their ecological adaptability—showing similarities with the subsistence activities of Homo sapiens in the Upper Paleolithic.”

“Their diet ranged beyond traditional medium-to-large mammals like horses, bovids, and deer to include numerous small mammals such as leopards, birds, and reptiles, even incorporating massive straight-tusked elephants (Palaeoloxodon antiquus), which could weigh up to 135 tons.”

“Additionally, evidence indicates that Neanderthals consumed freshwater and marine resources, including shellfish and crabs, throughout the Mediterranean Basin and southwestern Iberian Peninsula.”

The latest study investigated fragments of a 125,000-year-old turtle shell unearthed in Neumark-Nord, a renowned Paleolithic site in present-day Saxony-Anhalt, Germany.

Utilizing advanced 3D scanning technology, researchers discovered cut marks on the interior surfaces of many of the 92 shell fragments. This indicates that Neanderthals carefully slaughtered these turtles, severing their limbs, removing internal organs, and thoroughly cleaning the shells.

“Our findings provide the first evidence that Neanderthals hunted and processed turtles beyond the Mediterranean region and north of the Alps,” remarked Professor Gaudzinski-Windhauser.

Researchers believe that the turtle identified was a European pond turtle, which was not primarily utilized as a food source.

Professor Gaudzinski-Windhauser added, “Given that the site is rich in large, high-yielding animal remains, this possibility can be virtually dismissed.”

“It seems they had an ample surplus of calories.”

“The pond turtle weighs about 1 kilogram and offers relatively low nutritional value, yet they are fairly easy to catch. Children may have participated in hunting them, as their shells could have been crafted into tools.”

“Furthermore, they might have been pursued for their taste or potential medicinal properties, a notion supported by subsequent research on indigenous populations.”

“Our results illuminate Neanderthal ecological flexibility and intricate survival strategies that extend well beyond mere calorie maximization.”

The team’s results were published in today’s edition of Scientific Reports.

Unlock the Benefits of Fasting: Enjoy Health Gains Without Skipping Meals

The advantages of fasting are well-documented. Research indicates that fasting can lower blood pressure, reduce inflammation, control blood sugar levels, and naturally promote weight loss. The downside, of course, is that it involves abstaining from food.

But what if you could enjoy the same benefits without completely cutting out food? Enter the Fasting Mimic Diet, designed to offer similar advantages while allowing for some consumption.

This diet restricts overall calorie intake and protein consumption but permits small servings of plant-based foods, including vegetable soups, leafy greens, nuts, and seeds.










Adhere to this diet for 5 consecutive days each month. Start with burning 700 to 1,100 calories on the first day. For the subsequent four days, limit your intake to no more than 750 calories, with macronutrient distribution of 10% from protein, 45% from carbohydrates, and 45% from fat.

Similar to traditional fasting, this diet triggers a state of “cellular housekeeping,” which allows cells to break down and recycle old and dysfunctional components like proteins and organelles. This process promotes cellular energy, function, and prevents the accumulation of defective proteins that contribute to cancer and neurodegenerative diseases.

A 2023 study found that fasting-mimicking diets could help with symptoms related to prevention and treatment strategies for Alzheimer’s disease, although further research is essential. Additional studies have revealed benefits like cholesterol reduction and improvements in other cardiovascular biomarkers.

However, current research on this diet remains limited, especially concerning its effects on humans. Nutritionists advise caution; it may not be suitable for pregnant women, those who exercise vigorously, or individuals with a history of eating disorders. Even healthy adults might experience side effects such as dizziness, fatigue, and headaches. Always consult your doctor if in doubt.

Astronomers: Massive Black Holes Can Create Their Own Meals

New data from a very large telescope between NASA's CHANDRA X-Ray Observatory and ESO provides evidence that explosions from ultra-large black holes can help you cool the gas and feed yourself.



These images indicate two galaxy clusters of research, Perseus cluster and Centaul scraster. The chandradata represented by blue reveals X -rays from hot gas filaments, and VLT data indicates a red cooler filament. Image Credit: NASA / CXC / SAO / OLIVARES et al. / dss / cfht / sitelle / ESA / STSCI / ESO / VLT / MUSE / N. wolk.

In a new study, Dr. Valeria Olibales and her colleagues of Santiago De Chile University analyzed the deep observations of seven galaxy clusters, which indicate a remarkable poly-phase filament structure: Perseus, M87, Centaur, Abel 2597, Abel 1795, Hydra-A, Hydra, and Hydra PKS 0745-191.

“At the center of the galaxy cluster is the huge galaxy in the universe. This galaxy has a huge black hole with millions to billion times a mass of the sun.” I said.

“The jet from these black holes is driven by the black hole that exhales gas.”

Their results support a model in which the explosion from the black hole causes hot gases and cools down a narrow gas filament.

Gas turbulence also plays an important role in this trigger process.

According to the model, some of these warm gases in these filaments should flow into the center of the galaxy and supply them to black holes, causing explosions.

The explosion cools more gas, supplies black holes, and leads to further explosions.

The model predicts that it is related to the bright gas and warm gas filament at the center of the galaxy cluster.

More specifically, in areas where hot gas is bright, warm gases need to be brightened.

“Our results provide a new understanding of filament filled with these gases. This is important not only for feeding black holes, but also for forming new stars.” The person said.

“This progress has been made possible by innovative technology that separates hot filaments of Chandra X -ray data from other structures, including a large cavity of hot gas created by a black hole jet.”

“The newly discovered relationship of these filaments indicates the remarkable similarity of what is found in the tail of the jellyfish. These are peeled off when moving the surrounding gases and the long tail. It was formed.

“This similarity means that the universe connection between the two objects is revealed and that these objects have a similar process.”
