A new study reports that some monkeys show an intuitive ability to recognize and match geometric shapes in ways that resemble human performance. Researchers tested primates—reported as baboons and macaques—using tasks that involve identifying shapes even when those shapes are rotated. The results indicate that monkeys can use strategies comparable to those used by humans and children, rather than relying on entirely different mental systems. The study suggests that the cognitive mechanisms underlying geometric understanding may have deeper evolutionary roots, potentially extending to a common ancestor shared by monkeys and humans. By comparing how different primates and humans handle the same kinds of geometric stimuli, the researchers conclude that similarities reflect shared processing approaches for shapes, including abstract reasoning about form and orientation. Overall, the findings are presented as evidence that basic geometric intuition predates modern humans and builds on primate cognitive foundations.
