So I am being deliberately self defamatory n the hope some people will bypass this. It is a genuine request for those who have knowledge to look and comment.
It starts with the assumption that Irreducible systems exist (maybe that will stop some here)
Ok so let’s postulate using known conditions… If you both follow and understand it, perhaps you could tell me of a known theory that matches it or comes close?
The only answer to IC is that there is already a system in place to do the function of the new integrated system., so how might this new system develop?
It starts as a cancer. Neutral or wrongly developed cells. They qualify as your neutral drift. The cancer is benign in terms of development and not being lethal, and not enough to cause any disadvantage to the “Host” creature.
As time progresses the cancer takes a form which amounts to a parasite. It is now drawing off the host but still not killing it and the creature can still live, even thrive.
Eventually the system becomes fully functional and becomes symbiotic. It is now a benefit.
Now the old system becomes redundant. and slowly reduces perhaps becoming vestigial or only occurring in the foetal development.
The new system is now fully integrated.
All those conditions exist. And you can probably find data to back up this theory.
However, there are some major plausibility issues in terms of why such a thing should develop (other than it is quite a nice progression). Isn’t this building? (yes) and isn’t that against Evolutionary concepts? (Why should it?) and doesn’t it fly against all probability that there could be developmental progressions? Isn’t it far fetched? And so on, but
Nature (or God) does not have to conform. Not to human credulity, or human notions in any shape or form. If it could happen why not?
So the question is could this happen? (And has anyone ever thought of it before?)
