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 in 1901. He discovered that evolution can happen through sudden, random, and heritable changes in genetic material, rather than just slow, gradual ones. He coined the term “Mutation” to describe these “sudden changes” after observing them in the evening primrose plant.
