尼安德特人125,000年前开始提炼脂肪：新证据

"...A groundbreaking study published in Science Advances have revealed new evidence about Neanderthal survival strategies, suggesting they were rendering fat from animal bones nearly 125,000 years ago—long before modern humans developed similar practices. This discovery significantly shifts the understanding of Neanderthal behavior, showing that they engaged in more sophisticated methods of food processing than previously recognized...."

"...Neanderthal “Fat Factory”: A Closer Look at Their Bone Processing..."

"...Notably, the bones were cracked, boiled, and then skimmed to extract fats—a technique that allowed Neanderthals to supplement their protein-heavy diet, which could otherwise result in protein toxicity...."

"...Massive bone processing...."

"...creating the impression of a “bone floor” produced by Neanderthal activity at the site...."

"...The discovery of this “fat factory” predates similar evidence of fat rendering by modern humans by thousands of years, changing the timeline of early human food processing...."

"...suggesting that the Neanderthals had an advanced understanding of how to extract and store fat from their prey for later use...."

"...resulting in typical coloration (ranging from dark brown and black to white) and texture commonly found in heated bones. Credit: Kindler, LEIZA-Monrepos..."

"...Fat was an essential macronutrient for Neanderthals, especially considering the high caloric demands required by their hunter-gatherer lifestyle...."

"...The extraction of fat from animal bones allowed Neanderthals to avoid “rabbit starvation,” a potentially fatal condition resulting from excessive protein intake...."

"...This adaptation would have been crucial during the winter months, when plant-based foods were less abundant, and fat from animals provided a much-needed source of energy to help sustain them through lean times...."

"...By processing fat-rich bones, they were able to create calorie-dense food sources that could be stored for later, providing them with the necessary energy to survive through difficult months when other food sources were limited...."

"...This ability to adapt their food processing techniques likely contributed to their survival in challenging environments...."

"...A Peek into Neanderthal Adaptability: The Evidence at Neumark-Nord..."

"...The Neumark-Nord findings not only reveal Neanderthal food processing strategies but also highlight their resourcefulness in utilizing available materials...."

"...which likely facilitated the boiling process for extracting fats...."

"...which indicates that the Neanderthals were intentionally transporting and processing large quantities of bones from multiple animal species...."

"...Interestingly, the excavation also uncovered signs of sophisticated tool use, including anvils and hammerstones, which were likely employed to break the bones and extract the fat...."

"...These findings indicate that the Neanderthals were not just simple hunters but rather sophisticated foragers with a deep understanding of their environment and the resources available to them...."

"...The large-scale processing of animal bones for fat extraction was likely a collective effort, with Neanderthals working together to ensure the community’s survival during periods of scarcity...."
