Encontraron que los cambios en el canto se deben a muchos genes pequeños que afectan tanto el circuito motor como el auditivo.","fuente":"biorxiv","fuenteNombre":"bioRxiv · preprints","color":"#be2628","autor":"Gazda, M.

Entender cómo se combinan muchos genes para producir un cambio tan grande ayuda a entender la evolución del habla humana, que también depende de aprender sonidos y escucharse a uno mismo. Es una historia sobre cómo la paciencia de criadores y la genética pueden reescribir un comportamiento complejo.","quienFirma":"bioRxiv (preprint; grupo de neurobiología y genética del canto)","confianza":"preprint","consulta":null},"sello":{"hash":"2ebcc5ef096e64225cb6e085dd25e571b846b7c4fba2a903b5c05f45e084c7d6","sello":null,"beacon":null,"verificacion":null,"tsa":{"time":"Oct 20 12:17:24 2026 GMT","provider":"freetsa.org"},"original":{"titulo":"ARTIFICIAL SELECTION DIVERSIFIES BIRDSONG THROUGH POLYGENIC CHANGES ACROSS SENSORY AND MOTOR SYSTEMS","descripcion":"Vocal learning, or the ability to acquire and produce contextualized sounds through social interaction, underlies human speech yet has evolved in a few animal lineages, including songbirds. In songbirds, learned song is produced by a dedicated neural circuit and depends on auditory feedback for its acquisition and maintenance. Roughly four centuries of artificial selection on the domestic canary (Serinus canaria) have produced song breeds whose vocalizations diverge as much as those of distinct species, offering a rare intraspecific system in which to identify the genetic and neural changes underlying vocal divergence. Here we show that selection for song reshaped the canary song control sys","pubDate":"2026-10-20","url":"https://www.biorxiv.org/content/10.64898/2026.10.18.759937v1?rss=1"},"indexado":"2026-10-20T12:15:39.527Z"}}
