Crows Display Remarkable Geometry Skills

fast Summary

• A study led by neurophysiologist Andreas Nieder from the University of Tübingen, Germany, shows crows possess remarkable geometric cognition.
• Published in Science Advances, the research explores how crows identify subtle differences in shapes based on irregularities and geometric properties.
• Crows correctly distinguished outlier shapes on a digital screen-progressing from obvious differences to nuanced variations like skewed quadrilaterals among symmetrical ones-with minimal training and continued even without rewards.
• The findings challenge assumptions that advanced Euclidean geometry recognition is uniquely human, suggesting broader animal cognitive capabilities.
• Experts believe this skill may stem from evolutionary needs like spatial navigation or recognition of faces for mate selection or individual identification.
• While humans have cerebral cortex-driven cognition,birds achieve similar intelligence through simpler neuron arrangements,showcasing an alternative evolutionary pathway for behavioral flexibility.
