The more lazy and not using the brain, the more the brain will become like a rusted chain, hard to operate normally.
This saying had quite a market in the early days of modern biology and was once regarded by many as a truth.
However, biologists of later generations all know.
The theory of use and disuse is a relatively idealistic theory; it has no problem with individual variations, but it is not very applicable to species.
Because the theory of use and disuse believes that evolution and degeneration only change organs, but genes remain unchanged.
Just like the fish in the deep sea.
Due to the lack of light in the deep sea, deep-sea fish basically have no vision; their eyes degrade and lose their function.
But according to Lamarck's thoughts, the genes of these fish will not change.
So the newly born deep-sea fish would all have vision and little Yanzi-like eyes, which would then slowly degrade into Li Ronghao.
