However, new research shows that this ability is shared with primates. ## Monkeys and Shape Perception Experiments in laboratory settings have proven that monkeys perceive shapes similarly to humans. This finding points to common evolutionary origins. ## Research Methodology Researchers measured monkeys' reactions to different geometric shapes. The results showed that monkeys can categorize shapes like humans. ## Evolutionary Connection This finding strengthens the evolutionary connection between humans and primates. The origins of geometric intuition may trace back to common ancestors. ## Laboratory Findings The experiments revealed that monkeys' shape perception is almost identical to humans'. This proves that primates' cognitive abilities are more advanced than previously thought. ## Significance and Implications This research highlights the similarities between human and primate cognitive abilities. It raises new questions about the evolutionary origins of geometric intuition. ## Sources covering this story - https://www.nytimes.com/2026/07/21/science/monkeys-cognition-shapes-geometry.html — --- _Summary written by Brifing from the original reporting.
