π¬ Ancient Primate Brains Reveal Vision's Role in Evolution
Scientists reconstructed ancient primate brains by analyzing fossil skull interiors to understand brain evolution. The study, led by Richard F. Kay at Duke University, examined skulls from the Natural History Museum of the Duke Lemur Center. Findings from 2024 challenge old ideas, showing the frontal lobe grew proportionally, not independently. Instead, visual processing areas expanded rapidly, suggesting vision drove neocortex growth. This points towards high-definition vision as a key driver for large anthropoid brains. π§
