Why is it so important that the hunters stay on the path in the book A sound of thunder?

In Ray Bradbury's "A Sound of Thunder," it is crucial for the hunters to stay on the path to prevent altering the past and triggering unintended consequences in the future. The time-traveling expedition is designed to ensure that no changes are made to the prehistoric environment, as even the smallest disruption could lead to significant shifts in history. Staying on the path protects the timeline, emphasizing the fragility of the past and the potential dangers of tampering with it. Their failure to adhere to this rule ultimately leads to catastrophic results.
