"Darwin fish" replacing "Jesus fish"?

"Traditionally, the fish pictogram conjures the miracle of the loaves and fishes as well as the Greek word IXOYE, which not only means fish but serves as an acronym, in Greek, for "Jesus Christ the Son of God [Is] Savior." Christians persecuted by the Romans used to draw the Jesus fish in the dirt with a stick or a finger as a way to tip off fellow Christians that they weren't alone.

In America, the easiest place to find this ancient symbol is on the back of cars. Recently, however, it seems as if Jesus fish have become outnumbered by Darwin fish. No doubt you've seen these too. The fish symbol is "updated" with little feet coming off the bottom, and "IXOYE" or "Jesus" is replaced with either "Darwin" or "Evolve.""
