Assuming a biological essay for me for language suggests that we should be able to identify genes related to language acquisition.There are several genes that seem to affect language learning. Researchers are studying the members of one family, known as the KE family, because they have severe language deficits. Family members show a mutation in the FOXP-2 gene, which is also suspected of mutating about the same time humans probably began using language, approximately 100,000 years ago.
