Document Summary
Why did humans evolve language: language is an evolutionary adaptation and independent of intelligence. Genetic mutations in family produced severe language de cits despite normal. Even deaf children can quickly learn sign language. If no-one teaches them, they invent one of their own. Uniformity of language structure: language is universal in human populations, humans learn language early in life and seemingly without effort. There is likely a sensitive period for language acquisition that is from about 1 to. Language regions: in 1861, paul broca con rmed through postmortem studies that language production is localized in the left frontal lobe. Patient tan : karl werneicke later describe an area in the left temporal lobe important for language comprehension. Language disorders: aphasia - an impairment in language ability caused by brain injury, usually to the left hemisphere. Broca"s aphasia - dif culty with speech production but comprehension is intact.
