You're welcome, Gilbo.
Irreducible complexity is a good subject too.
I would add that Werner Gitt's contribution to understanding information in a way that Shannon Information only deals with data is vital too.
Data in the form of code has it's ambiguity problems. Gitt's work lays the groundwork for defining information as a feedback loop. Measuring data content can have its place but understanding the roles of sender/receiver/purpose is much more robust at detecting the reality of design as a deliberate action versus patterns that 'just happen'.
To be honest I totally forgot about the sender / receiver relationship of information within cellular systems, I used to post here about it frequently.
For those reading, the cells signal cascade system is a great example of something having a design due to the sender / receiver relationship.
We should ask
- how does the cell 'know' that gene X activates function X
This is in order to allow for the signal cascade system to function. In order for the function to be used effectively its function needs to be known, as well as the gene that operates it.
- how does the cell know what function function X performs?
In order to have a signal cascade system the cell would need to 'know' the effect function X would have, thus allowing for the initial settings for the cascade system to turn the function on. This is to ensure that the function is being used efficiently since wasted efficiency is wasted resources for the cell leading to a lack of fitness. For example if a function is to create a protein for the cell membrane then the signal system would need to be based on recognizing when a lack of this protein is present. Producing proteins willy nilly is going to lead to a decrease in efficiency and thus fitness and would not be selected for by natural selection.
- how does the cell 'know' what factors enable function X to function?
This relates to the multitudes of checks and balances in the cellular system. There are many MANY regulatory systems that are in place for each cellular system to ensure that the system is operating at peak efficiency. How could the system function without these regulatory elements? Remember a decrease in efficiency would defy natural selection
I've probably missed some points but that is largely the gist of it.
The issue here is that there are only two logical solutions (well actually three)
1- Cells are sentient
2- Natural selection doesn't matter that much, and cells can live whilst producing proteins willy nilly
3- The systems are designed
