Open system theory applied to evolution.

Your post here only applies to a system that already exists and assumes that mere energy in is enough to account for the origin and variety of life. It isn't

Yes, it only deals with a system that already exists. This is a well known limitation of the theory of evolution - the theory only addresses changes once life had started and does not address the origins of life.

There is more to the theory than just energy (and food and water). The diagram also deals with the impact of the environment (point 1) and the part played by information (point 5) (natural selection in the case of the theory of evolution).
