Electric fish have developed in six different lineages, all separate, all from muscle modification, as an amazing example of convergence:-"These fish have converted a muscle to an electric organ," explains Sussman, a professor of biochemistry and director of the UW-Madison Biotechnology Center, who first undertook the exploration of the electric organ almost a decade ago. The study published in Science provides evidence to support the idea that the six electric fish lineages, all of which evolved independently, used essentially the same genes and developmental and cellular pathways to make an electric organ, needed for defense, predation, navigation and communication."- Read more at: http://phys.org/news/2014-06-truth-electric-fish.html#jCp
