I just found a good paper from the Entropy Journal called: Self-Organization of Template-Replicating Polymers and the Spontaneous Rise of Genetic Information. When I read it I was surprised how original it is and how simple open-ended systems might be. It also makes you think that a sytem that displays open-ended evolution might not be possible in a computer but in a mechanical system. Maybe there is something about electromagnetic fields and fluid flow that can’t be recreated in a computer. Probably not and it’s more a question of when but it’s a possibility. It is obiously possible using chemistry because it happened already so I won’t be surprised when Mark Bedau does it.
