Remarkably, although all vocal learning species are distantly related and have closer relatives that are non-vocal learners, humans and the vocal learning birds have evolved convergent forebrain pathways that control vocal learning. It has evolved multiple independent times among mammals and birds. Vocal learning is the most critical behavior for spoken language. Professor and Head of the Laboratory of Neurogenetics of Language,
