The wings of pterosaurs (1), bats (2) and birds (3) are analogous as wings, but homologous as forelimbs. Evolutionary ancestry means that structures evolved from some structure in a common ancestor; for example, the wings of bats and the arms of primates are homologous in this sense.
â¦ Broca's area is located in the left frontal lobe, in close proximity of primary motor cortex. Wernicke's Area â¦ Wernicke's area sits in the left temporal lobe, very close to the auditory cortexâthe area involved in hearing.
In most people (97%), both Broca's area and Wernicke's area are found in only the left hemisphere of the brain. In the early 1950s, the famous neurosurgeon Wilder Penfield and his colleague Herbert Jasper, described how electrical stimulation of certain areas of the brain blocked language.n most people (97%), both Broca's area and Wernicke's area are found in only the left hemisphere of the brain.
