Stone Age, humans who live next to a lake in what is now systematically treated from animal bodies for fatty nutrients – mainly run what scientists describe as a “fat plant” to boil the bones on a large scale, according to a new research.
Archaeologists have revealed the factory by analyzing about 120,000 bone fragments and 16,000 Flint tools that have been discovered over a period of several years at a site known as Neumark Nord, south of Halley, according to a study published on Wednesday in the Journal of Science Advances. The excavators found the artifacts along with evidence of the use of fires.
Researchers believe that primitive humans, an extinct type of human being known to have lived in that region up to 125,000 years ago, destroyed the bones rich in marrow in fragments with stone hammers, then boiled it for several hours to extract fats, which float on the surface and can float on cooling.
Since this fertility work would include fishing planning, transferring and storing post -nutritional bodies, making fats in an area specially dedicated to this task, the result helps to draw a picture of the group’s organization, its strategy and survival skills deeply.
“This position is that the primitive human beings were stupid – this is another data point that proves otherwise,” said Will Robrox, a co -author and ancient archaeological professor at the University of Leiden in the Netherlands.
A series of archaeological discoveries in recent decades showed that primitive humans have been more intelligent than the original brutal stereotype. The old people lived throughout Eurasia and disappeared 40,000 years ago, and previous studies found that they were made yarn and glue, Engraved bones and Cave wallsAnd the collection of jewelry from Eagle claws.
Details in the new research indicate that primitives may be unexpectedly developed in their approach to nutrition as well.

The threat of protein poisoning
Also, the primitive study that lives on the German site for 300 years clearly understood the nutritional value of the bone blade that it produced, according to the study.
A small amount of fat is an essential part of a healthy and balanced diet. The material was more important for the fishermen’s collectors, such as primitive humans, who are likely to rely heavily on animal foods.
The diet dominated by protective meat and lack of fatty acids can lead to a delusional and sometimes fatal shape of malnutrition, as the ability of liver enzymes to destroy protein and get rid of excess nitrogen. Today is known as protein poisoning, the situation has gained a reputation among the first European explorers in North America as “rabbits” or “Mal De Caribou”.
Both fishermen like primitive humans, with average body weights between 50 kilograms and 80 kilograms (110 lbs and 175 rugs), could have to maintain their consumption of dietary protein less than 300 grams (about 10 ounces) per day to avoid the condition. This reaches about 1,200 calories – a level of income much lower than daily energy needs, according to the research. As a result, primitive humans may need to obtain the remaining calories from a non -protein source, either fat or carbohydrates.
The pieces of meat from animal muscles contain a little fat, bone making – that contain a marrow and other fatty tissues even when the animal is malnutrition – a more important resource.
The researchers have discovered that the vast majority of the remains on the site came from 172 large individual animals, including horses, deer, and euros, the large creatures that resemble the cow that are now extinct. The study found that primitive humans chose the longest bones that would have included most of the core.

ACORN Drink, Sloe Plugs
Exactly how primitive human treated bones are unclear, according to the authors of the study. Robrox said that old humans most likely make containers or utensils from birch bark, animal leather or other parts of the body such as stomach blankets, fill them with water and hang them over the fire.
Premium humans could consume the fats produced by a “fatty broth” that had been added to the plants as well as the nutritional value, as Jeff Smith, the first researcher in zoing at the University of Reiding. He pointed out that the charred residues of hazelnuts, pepper and sink SLOE were also found during excavations.
“These simple fishermen were not getting day to day-they were a major planner who could look forward, organize complex tasks, and pressure all the last calories of their environment,” Smith said.
The results are “exciting”, according to Ludovic Selim, the archaeologist at the French National Center for Scientific Research (CNRS) and the University of Paul Sabatiye in Toulouse, France. Selimak did not participate in the study.
“They finally provide a clear archaeological confirmation of what many of us have suspected for a long time: that Neanderthals not only appreciate fat inside the bones, but they have developed specific strategies to extract and address them.” It will be published in English later this year.
He added: “This is closely corresponding to the broader archaeological registry, which shows that primitive humans as hunters in the big game with high skills with a feeling of entry into environmental adaptation.”
“The best example so far on bone width”, since this period of the Stone Age. Hardy also did not participate in the research.
“A mixture of evidence here in Neumark Nord is impressive,” Hardy said. “The amazing pistol, or amazing bone broth may be to serve primitive bones.”
