The name Sonic Hedgehog originated with a mutant fruit fly embryo that had cuticle all over its body. Researchers found three different versions of the "hedgehog" gene but only two kinds of real hedgehogs, so they named the third gene after the cartoon character.
For all you naysayers that don't think the name had anything to do with the video game...:)
