Perhaps you could tell me what page “devolution” is included?
No I can’t. It’s not his word. He doesn’t talk about devolution in the paper I linked to. He talked about gain of function and loss of function mutations. He shows that many mutations that are beneficial, i.e. provide some advantage in competing for food or resources, and allow faster growth, are loss of function mutations. Something gets deleted or broken because it is unnecessary at the moment, or it is an energy hog, and suddenly the cell bearing that mutation grows faster.
I can give you many examples from my own work, but this is the most striking. Yeast cells grown for generations under conditions that promote asexual reproduction, will delete their own genes for sexual reproduction.

Call it devolution if you want.
