Functional MRI was used to test predictions from a theory of the origin human language. The gradual suggests that language and tool-use skills have similar hierarchical structure, proposes tool-manipulation are related evolution Our results show an overlap brain activity for perceiving using tools in Broca's area. location this tool use share computational principles processing complex structures common these two abilities. involvement monkeys' homologous region during neural processes computation exist primates without language, could been exapted support grammatical ability.
