Ancient Gibraltar Hearth: Neanderthal Glue Production Site?

Archaeologists have uncovered a 65,000-year-old hearth in Gibraltar, believed to be a Neanderthal "glue factory" used to produce tar for hafting tools and weapons. This discovery highlights the Neanderthals' advanced engineering skills, as they precisely controlled fire to distill resin from rockrose plants. The process involved creating a sealed environment to prevent oxygen from burning the resin, showcasing their ability to manage complex tasks and work collaboratively.
