Looking at what we have now doesn\'t give us direct access to what it might have evolved from.
It seems unlikely that these refinements are strictly necessary to the process of self-replication in the simplest possible cell that can self-replicate.

Craig Venter and his team put together a self-replicating cell that had just 473 genes. Sadly, they didn\'t know what 149 of the genes actually did.
The work got published in Science on the 25th March 2016. Presumably we know a little bit more now.
Probably not. People who pontificate about stuff the don\'t actually understand need to recognise that they need to learn more. My experience is that you do have to be pretty direct to get them to recognise that they do need to learn more - polite formulations don\'t get their attention.
John Larkin does seem to be remarkably resistant to any suggestion that he doesn\'t know as much as he ought to - he does interpret them as threats to his vanity and self-esteem.

That\'s a meaningless phrase and concept.
It says and means exactly that a mechanism is complex and simpler
subsets don\'t work. It\'s a common concept.

If you know of a cell replication mechanism that is simpler than the
one we have, please tell us about it. I especially like that 10,000
RPM DNA unwinder thing, and the bit that copies one strand in segmemts
in reverse. And the funny things that walk around carrying things.

It is as vacuous as the concept we saw as kid, that the key living part of the cell is \"protoplasm\".
You should have more faith in mankind\'s intellect.
You should be more polite.
