Answer 1

The causality behind the sudden changes was understood due to mutation principle of Hugo de Vries.

Explanation:

Hugo de Vries proposed the mutation theory to explain that evolution can happen through sudden, large, and inheritable genetic changes called mutations. Before this, scientists believed evolution only happened through very slow, gradual changes. De Vries’ principle provided the reason (causality) for how completely new traits could suddenly appear in a single generation.
