Sorry but that is simply wrong as evidenced by [this simple model.](https://discourse.peacefulscience.org/t/evolving-motion-and-neurosystems-in-soft-robots/7637)

Sanford’s “genetic entropy” has been thoroughly refuted and rejected by the scientific community. The paper you site does not accurately model evolution because it uses a constant, non-changing environment. In the real world environments are always changing and providing new opportunities for evolution to explore with new variations.
