A basic objection (from Fred Hoyle etc.) is from information theory – new information content cannot increase in a closed system. This limitation is overcome by including diverse and variable environments in the system – surely the changing environment is an essential driver of diversity, I commented. Ability of organisms to adapt to environmental variations is analogous to stability of inanimate systems or stability of ecosystems (containing a complexity of organisms).
