Un nuovo studio pubblicato dal Journal of Science ha svelato il segreto che si cela dietro lo sviluppo di organi elettrici in particolari tipi di pesci.
Benché si distinguano sei distinti gruppi evolutivi di questi animali elettrofori (molto diversi per forma e habitat), degli scienziati hanno individuato una particolare sequenza di geni che li accomuna.
"Gli organi elettrici hanno un'origine muscolare", spiega Jason Gallant dell'Università del Michigan. "Attraverso una serie di sviluppi, diventano più grandi, più eccitabili elettricamente e perdono la loro capacità di contrarsi".
