Language as Shaped by the Brain

How did we get the gift of the gab? Since the dawn of time, humans have wondered about how we got our amazing ability for language. The current scientific understanding of language evolution sees it as primarily involving the evolution of languages themselves rather than biological adaptations of the human brain. That is, language evolved by ‘piggy-backing’ on pre-existing neural mechanisms. Repeated cycles of cultural transmission across generations of language learners and users have shaped the different aspects of language into what we can observe today across the world. In the CSL Lab, we explore the theoretical and empirical implications of the cultural evolution of language, including specific cognitive constraints that have shaped language, such as the Now-or-Never Bottleneck.
