In more recent years I discovered that genomes and higher order cellular processes such as chemotaxis work the same way.

I wonder if you meant to say gene pool rather than genome. After all, a gene pool does keep a record of sorts of things that worked (while not keeping a record of things to avoid doing again), and it has a way of trying lots of minor variations (although no way of reliably trying large variations to rewrite something that was done badly).

The gene pool still relies on single individuals to come up with unique solutions to problems such as digesting nylon, antibiotic resistance, differentiation into new cell morphologies.

At the "molecular intelligence" level the gene pool is a "collective intelligence" or more specifically "molecular collective intelligence".

Did the single bacterium that according to your theory invented nylonase somehow sensed nylon? In other words how did it become aware of the fact that nylon can be digested and how did it then develop the idea that changing the coding sequence of another proteinwould produce a protein degrading nylon?

That's another largely unknown area of science, and the phrase "random mutation" is misleading since there might be a "good guess" mechanism which caused the coding change (at the molecular/genetic level) by sensing a potential new food source. Something similar (although not bacterial) to what I am describing is Somatic hypermutation (preferably of a newly duplicated gene which are known to relatively quickly change).

The theory of intelligent design holds that certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection.
