Crows seem to understand geometry — and we thought only humans could

In a remarkable new study, crows demonstrated an intuitive grasp of geometry—identifying irregular shapes without training.

Now, a recent study has awarded them a skill that has only been observed in humans so far. This capacity involves the geometric perception of irregular forms without having received any previous teaching. The finding, published in the prestigious journal Science, challenges traditional ideas about the cognitive abilities of non-human animals. Researchers from the University of Tubinga, Germany, carried out a series of experiments with carrion cr…
