That depends on how you define 'system'. Is 'system' the entire biological existence of earth? In that case, yes evolution would be a mathematical certainty eventually. But is system a specific species? In that case evolution would only occurr within those species.

He goes on to tell you exactly what systems: any with random heritable changes that can selectively help or hinder reproduction. This would mean both all life on earth that fits within that definition, and any particular species also under that umbrella.

It seems to me like you're trying to make a distinction between "microevolution" and "macroevolution" here, but I may be misreading you. If you are, however, notice that thomblake's process makes no distinction between them; to suppose one but not the other could occur, you'd need a specific mechanism or reason.

Also, time is another factor. Your explanation logically does not necessitate that evolution has already happened, only that it will eventually happen.

No, it necessitates that it is happening and has happened in any such system. The process, that is. You're correct if you're just saying that the process may not have resulted in any differentiation at any given time.
