Who destroyed the idea of the immutability?

The idea of immutability, particularly in the context of scientific theories, was significantly challenged by the work of Charles Darwin. His theory of evolution introduced the concept of natural selection, demonstrating that species change over time rather than being fixed. Additionally, advances in fields like genetics and Paleontology further supported the idea that biological entities are not immutable but rather subject to change and adaptation. This shift fundamentally altered our understanding of life and its development on Earth.
