FOXP2 And Language Development

Decent Essays

Like previously discussed, FOXP2 is one of the most recent discoveries of a gene most likely related to language development, however, it is also involved in language impairment, influencing a new area of study within the genetic and evolutionary anthropology field. The authors of “Identification of FOXP2 Truncation as a Novel Cause of Developmental Speech and Language Deficits” state that this gene has derived within the past 200,000 years as the result of positive selection, which aligns with Pinker’s theory that there is a gene responsible for language development that has survived natural selection. The article states that because of this, FOXP2 “may have undergone human-specific modifications at a time when spoken language was emerging” …show more content…

The blank slate is a theory utilized by some linguistic analysts that believe people are born with no innateness or hardwiring from genetics, but rather develop their character through the influence of their surrounding culture. Pinker strongly claims in his Ted Talk entitled, Human Nature and the Blank Slate, that children are born with predisposed traits, although everyone shares similar behaviors and feelings, such as “aesthetics, affection, and age statuses,” and even refers to this as “common sense.” Pinker also uses genetic science and neurobiology to disclaim utilizations of the blank slate as an explanation for language development. A study done by neurobiologist Paul Thompson measured grey matter in areas of the brain between different pairs of people. Those who were unrelated showed no similarities while fraternal twins shared many, and identical twins, who share much of their DNA, showed a large amount of resemblances, proving that genetics are more influential than culture in shaping character. He ultimately claims that scientific studies show that biological siblings separated at birth are more identical in personality than adopted siblings sharing the same household because he says that “everything that happens to you in a given home over all of those years, appears to leave no permanent stamp on your personality of intellect.” He controversially argues that many people, like Skinner, adopt the blank slate theory because if people are blank slates, then it can be assumed that everyone is equal, however denying this assertion justifies prejudice and discrimination if one’s slate is not clean because they may have more of “it” than others, whatever the trait may be. The blank slate theory also leads people to
