Neanderthals residing 125,000 years in the past in what’s now modern-day Germany could have extracted and eaten fats from animal bones by an organized meals preparation course of that scientists describe as a “fats manufacturing unit.”
Whereas excavating the positioning of a former lake panorama known as Neumark-Nord, archaeologists found 1000’s of bones from no less than 172 massive mammals, together with flint artifacts. The bones, which date again to an interglacial interval by which Neanderthals lived, had been from animals like crimson deer and horses, based on a examine printed on July 2 in Science Advances.
Whereas most of the bones that contained much less bone marrow had been unfold out throughout the archaeological website, researchers noticed that most of the marrow-rich bones had been positioned in clusters — websites they name “fats factories.”
An image taken on September 6, 2021 exhibits the reconstruction of the face of the oldest Neanderthal discovered within the Netherlands, nicknamed Krijn, on show on the Nationwide Museum of Antiquities in Leiden.
Researchers consider our extinct ancestors used instruments to smash the bones into small fragments after which boiled them for hours. The grease, which then floated to the floor of the water, may very well be skimmed off the highest and eaten — offering a calorie-dense meals supply for the archaic folks.

Previous to this, proof of the follow had solely dated again to twenty-eight,000 years in the past, based on the analysis.

“Neanderthals had been clearly managing sources with precision — planning hunts, transporting carcasses, and rendering fats in a task-specific space,” Dr. Lutz Kindler, the examine’s first creator, stated. “They understood each the dietary worth of fats and the right way to entry it effectively — more than likely involving caching carcass elements at locations within the panorama for later transport to and use on the grease rendering website.
Fats was a “life-sustaining” useful resource for Neanderthals, particularly throughout the winter and spring seasons when carbohydrates had been scarce. Their diets consisted largely of animal protein, and consuming plenty of protein with out different vitamins may result in a typically lethal situation known as protein poisoning, the analysis famous.

“The sheer measurement and extraordinary preservation of the Neumark-Nord website complicated offers us a singular likelihood to review how Neanderthals impacted their atmosphere, each animal and flora,” Dr. Fulco Scherjon, knowledge supervisor and laptop scientist on the undertaking, stated. “That’s extremely uncommon for a website this previous—and it opens thrilling new prospects for future analysis.”
Lately, scientists have additionally found that Neanderthals went diving for seashells that they may chip with stone hammers into skinny and sharp chopping edges. Equally, one other examine steered Neanderthals could have buried their lifeless with flowers.
