Next step... dolphins (Score 1)

Well, as we work down Douglas Adams' ladder of earthly intelligence, I can't help but wonder if this will eventually lead to the fullfillment of the dream of those poor souls over at dolphinsex.org

Maybe a strain of super-human/dolphin hybrids will supplant mice at the top of the intelligence hierarchy.

Sorry, I know it's obscure, but hell, this story deserves it.
