Otro gen que susurra a los humanos

from Cienciaes.com

Desde hace décadas, los científicos estudian qué genes a lo largo de la evolución han sido los más importantes para que los humanos hablemos. Hasta ahora, el principal candidato era el gen llamado FOXP2. Los humanos poseemos una variante del gen FOXP2 que no poseen otros animales relacionados con nosotros, en particular no la poseen chimpancés o gorilas. Esta aparente exclusividad humana hizo creer en un principio que esa variante de FOXP2 era la que nos capacitaba para hablar. Gracias a los progresos en la secuenciación del DNA se ha podido obtener y comparar la secuencia de especies humanoides, como neandertales y denisovanos, así como de gorilas, chimpancés, orangutanes y bonobos. A partir de la comparación de esos genomas, se han identificado 61 genes cuyas variantes aparecen exclusivamente en la especie humana. Una de estas variantes génicas ha atraído mucho la atención de los científicos. Se trata de una variante del gen NOVA1, que produce una proteína que interacciona con el RNA en las neuronas y modula su función. Más información en https://cienciaes.com
