Well, I've always been partial to the Hitchiker's Guide theory that the Dolphins are way ahead of us: I see them staring in amazement at those "silly hairless apes" wasting their time building all those pointless contraptions. If you go over and take a look at Sanctus' thread on
anarchy and the aim of evolution, you might notice that Dolphin society very much resembles the nirvana in that thread...
Who's to say what "intelligence" really is?
The concept that I really like in this thread is the "panspermia" idea: its again very anthropocentric of us to assume that life had to have *started* on Earth, and with all that junk floating around, who's to say what a head start evolution got long before our Sun was even a difuse cloud of hydrogen gas?
