Rather than evolving only in humans, he argues that the PT continued to evolve in both species, but to accommodate different communications challenges. Humans expanded their territories and encountered new and different experiences that demanded novel communication skills. Dr. Gannon's research may lead to new insights into the origins of human language and speech, including the organization of language-related areas of the brain and their design and evolution. If the PT becomes activated on the left hemisphere, the part of the brain that controls communication, proof of its role in language outside of the human realm will be realized, and the doubt some scientists harbor about Dr. Gannon's findings will be erased. Humanlike pattern of Wernicke's brain language area homolog.
