Fossil Evidence Links Vision to Modular Evolution of Primate Neocortex
Key Takeaways
- Study published in Science (Vol. 393, Issue 6811, August 2026) analyzes fossil endocasts to examine neocortex evolution.
- Findings indicate that expansion of visual processing areas in primates was accompanied by coordinated modular reorganization of the neocortex.
- Supports hypothesis that vision was a key selective pressure in the modular evolution of the primate brain.
- Challenges previous models that emphasized overall brain size or general cognitive abilities as primary drivers.
