It is not essential that the whole circular network to be incorporated in a life-like system. A part of the network is accelerate by a newly evolved ribozyme is important. I tried to describe this, but it seems not sufficient. So I added carefully descriptions at lines 455 – 457, 466 – 471, 483 – 48
Statements such as in line 232: "the first step is to limit the characteristics of life-like systems into life on Earth" leave one scratching ones head.
