Unfortunately "natural law" is a phrase that sounds good, but no one can nail it down. You might as well substitute "elves" for "natural law" and come to the same result. Heh heh. Saying "natural law" sounds more scientific but that don't make it so.
This I have to strongly disagree with. Natural law - according to forces of natural world. Mutations have been observed to be caused by phenomena of the natural world - UV, cosmic rays, chemicals etc.
The "spaghetti code" (like that phrase) as you say, appears to be the result of well understood natural phenomena.
Examples: in the case of the defunct Vitamin C gene, there is a one base pair deletion found in primates. Deletions such as this have been shown to be caused by certain mutagens in the lab. Gene duplication is caused by unequal crossing over events during cell division - and it looks like this happened a whole bunch of times in human ancestors.
Why bring extraneous stuff like "elves" or "sub-sub contractors" into the mix?
