Scientists have found how the electric fish evolved its
jolt.
Writing June 27, 2014 in the journal Science, a team of
researchers led by Michael Sussman of the University of Wisconsin-Madison,
Harold Zakon of the University of Texas at Austin and Manoj Samanta of the
Systemix Institute in Redmond, Washington identifies the regulatory molecules
involved in the genetic and developmental pathways that electric fish have used
to convert a simple muscle into an organ capable of generating a potent electrical
field.
