The nice thing about evolution is that over billions of years, nearly any idea we can come up with has probably been "tried", be it genius or hare-brained (including putting brains in hares).

I remember seeing a program on TV years ago about how giving the hulls of airplanes a rough structure like the skin of a shark reduced their fuel consumption significantly.

So I expect more of these "inventions" to inspire engineers in years and decades to come.
