It has become increasingly evident to scientists that the intellectual prowess of your average crow has been roundly underestimated. With remarkable skills including superior social acumen, analogical thinking and the ability to craft and use tools, crows seem to prove themselves more and more clever with every investigation into the inner workings of their small, but mighty, brains.
Most recently, new research has revealed that crows may be capable of recursion, a hallmark feature of advanced linguistic ability originally posited by Noam Chomsky in his hierarchy of grammars. Recursion in language is used to grow the complexity of sentence structure to contain, in theory, an infinite number of embedded elements or ideas. Put simply, linguistic recursion refers to the nesting of one grammatical structure, this sentence for example, within another of the same kind. Formerly thought to be a skill exclusive to primates, research like that recently published in Science Advances has challenged this assumption.Continue reading “The Crows Have Ideas”
