Today I learned of the hedgehog signalling pathway, and its sonic variant. No, the OP wasn't making a subtle joke.



Was this the genesis of the game's name?

(Question is serious, but pun intended, sorry)


No. The pathway is named after the character.

Other way around. Wikipedia has a good summary. It’s difficult telling parents that the cause of their child’s holoprosencephaly is a gene called sonic hedgehog
