GENOME: Chromosome 7: Instinct

GENOME 7: Instinct In this chapter, Ridley talks about how genetic determinism is a lot more probable now. Ridley discusses how vocabulary is not an innate trait in newborns/humans, but grammar may be. He explains that this theory may be true because children, young toddlers, are able to speak correctly with the right usage of grammar. Chromosome 7 contains a gene that is linked to a disorder, a language disorder called Specific Language Impairment. The inheritance rate has almost reached 100%. With studies, SLI is connected to the inability to learn grammar correctly. The gene in chromosome 7 as stated in the book seems to have a cause in the lesion in the brain.
