The evolution of fish

Just a diagram showing the evolution of the fish symbol, originally a Christian symbol.  It seems like that the evolution- and food-linked symbols on the left have evolved a lot faster in their design than the religious ones on the right. The sushi symbol we saw in Durango, Colorado, this summer, at a Japanese restaurant of course!

(note the font - it is a new variant that needs to be added to the evolutionary tree above)

And talking about sushi, this looks delicious, doesn't it?
