Neanderthals made weapons from glue; 60,000-year-old ***** discovery stuns scientists

For centuries, Neanderthals were often portrayed as primitive, brutish beings. But a new discovery has challenged this long-held stereotype.

A Neanderthal glue-making structure has been uncovered at Vanguard ***** in Gibraltar.

Archaeologists found a specialized hearth or “burning structure,” which they believe was used to create a prehistoric superglue: birch tar.

This discovery provides evidence of their advanced *****-using techniques, suggesting Neanderthals were more intelligent than previously thought.

“Neanderthals were able to construct layered and complex hearths with specific technological objectives that could have included tool, medicine and/or ******* elaboration,” the researchers wrote in the study paper.

Glue used to make tools and weapons

The discovery was made within a sedimentary layer dated to the ******* between 60,000 and 67,000 years ago.

“We present multiproxy evidence of a new type of Neanderthal hearth discovered in Vanguard ***** (VC) (Gibraltar), which is dated 65 kyr, and associated with Middle Paleolithic stone artefacts,” the researchers wrote in the study paper.

The location includes several prehistoric human caves. These caves were among the last known homes of Neanderthals in Europe, and before they eventually became extinct.

The researchers suggest that the Neanderthals used the discovered structure for a specific purpose: heating rockrose plants under controlled conditions. To achieve this, they would have burned herbs and shrubs over a layer of guano mixed with sand.

The controlled environment, with limited oxygen, would have been crucial for the process of extracting birch tar from the rockrose plants.

Birch tar, a sticky, dark substance, served as a powerful adhesive, allowing the Neanderthals to craft tools and weapons with precision.

Neanderthals performed complex tasks

The team identified the hearth based on its ******** in this seaside *****.

The circular hearth, with its two channels and thick wall lining, deviates from the typical design of cooking ***** pits.

Moreover, the hearth showed evidence of burning resinous plants, including charred wood and specific plant compounds linked to tar production from birch bark. This suggests a specialized use beyond simple cooking.

The team hypothesizes that the structure was used to heat rockrose plants under controlled conditions.

“We propose that the structure was used for heating rockroses (Cistaceae) under anoxic conditions by burning herbs and shrubs, over a guano mixed with sand layer,” the authors stated.

The researchers built a structure similar to the one found in the archaeological site and attempted to replicate the process of producing birch tar. They successfully produced enough tar from rockrose leaves.

This discovery challenges the long-held stereotype, suggesting Neanderthals were capable of doing intricate tasks. Moreover,

Abstract

Here we present multiproxy evidence of a new type of Neanderthal hearth discovered in Vanguard ***** (VC) (Gibraltar), which is dated ∼ 65 kyr, and associated with Middle Paleolithic stone artefacts. The hearth structure coincides with predictions from theoretical studies which require the use of heating structures for obtaining birch tar, commonly used in hafting. We propose that the structure was used for heating rockroses (Cistaceae) under anoxic conditions by burning herbs and shrubs, over a guano mixed with sand layer. We tested this hypothesis experimentally with success. The presence of levoglucosan and retene in the structure’s matrix points to combustion of higher resinous plant-derived material. Our results advance our understanding of Neanderthal behavior, as the ability to organize activities related with the use of *****.
