Fiber Technology Pushes Back Cognitive Milestones: Fiber technology is the ability to process and manipulate plant fibers into things like string, ropes, clothing, and nets. It represents a milestone in cognitive abilities and cultural progress, requiring not just dexterity but also a deep understanding of material properties. The brains needed for this technology had to grasp both the time and the know-how to manipulate the environment in a very specific way.

Archaeologists in France uncovered a remarkable artifact at the Abri du Maras site: a flint tool entwined with twisted vegetal fibers, dating back 50,000 years. This discovery is the oldest known example of fiber technology, revealing that Neanderthals understood how to process and manipulate plant fibers into useful tools. The ability to create twisted fibers likely served as the foundation for making string, ropes, and possibly clothing or nets. This advanced use of natural resources demonstrates Neanderthals’ sophisticated cognitive abilities and their deep understanding of the natural world.

This Neanderthal find predates the earliest Homo sapiens evidence of fiber use by at least 14,000 years, challenging the long-held belief that such technology was exclusive to our species. It further supports the idea that many of the cognitive abilities modern humans rely on today—such as abstract thinking, planning, and innovation—were already emerging in our common ancestors around 440,000 years ago. This discovery adds to the growing evidence that Neanderthals were not simply brutish beings, but rather intelligent hominins with cultural and technological complexity.
