Medicine & TechnologyWhen it comes to cognition, there are few answers on the origins of many behaviors. Neurobiology and social anthropology help researchers understand the development of speech, the correlation of objects or words with physical entities, and even the emergence of faiths. However, when it comes to something as simple as a number line, which is virtually a universal means of discerning small numbers from larger numbers, researchers are stumped. And looking to nature for the answer, a new study published this week in the journal Science, discovered just how universal these number lines are.
While it may take children a couple of years to learn the true values of arithmetic, a new study conducted by ethologist Dr Rosa Rugani, from the University of Padova, reveals that newborn chicks can not only recognize number patterns but also place them in ascending order from left to right. In fact, while the cognitive ability to count may seem like an acquired trait taught to us in school, Rugani’s recent experiments prove that even those with bird brains can display a knack for “number mapping”.
