Now scientists havediscovered a change in a gene that might help explain the difference.The mutation of this gene seems to have helpedhumansdevelop speech and language. Researchers found the gene looks andacts differently in chimps and humans.   Lab tests showed that the humanversion has more than 100 other genes differently from the chimpversion. This particular gene, called FOXP2, mutated around the timehumans developed the ability to talk. Study shows this gene plays amajor role in chimp-human differences. If this gene is mutated, aperson get a disorder in speech and language. A  This discovery, however, led todifferent opinions. B Some researchers believethat working on this gene could potentially implement genetictreatments for people with certain evelopmental difficulties. C Other outside experts warned of focusing too much on thisfinding. While finding the genetic differences is good, it is tooearly and unclear to consider what it means for languageand cognitive development. Still others think that the key questionis not how humans developed speech and language, but "why did weget language." Just because humans developed the ability forlanguage, that doesn't mean it would happen automatically. Otherspecies gets along just fine without it.
