A Sound of Thunder

[corkoman]

Amazing that this author totally missed the origin of the Butterfly Effect - Bradbury's Sound of Thunder where the protagonist goes dinosaur hunting then returns to the present to find radical changes in the language.

The guy broke an important rule by stepping off the approved path. Upon inspection his boot had a butterfly wedged in the sole. Hence the impact of a small alteration of the past leading to something different in the future.

Ray Bradbury = an American treasure.
