I am not qualified to comment seriously on this article.
I wish you were because I have many questions.
I do not know why you posted this if you cannot.
Firstly, from the intro:
A recent information-theoretic (but intuitively evident) definition identifies genomic complexity with the amount of information a sequence stores about its environment.
In this paper, we skirt the issue of structural and functional complexity by examining genomic complexity. It is tempting to believe that genomic complexity is mirrored in functional complexity and vice versa. Such an hypothesis, however, hinges upon both the aforementioned ambiguous definition of complexity and the obvious difficulty of matching genes with function.
The model that they are employing may be analogous to some extent with what one observes in nature, but as they admit, they have made a number of assumptions whose applicability will require much further research.
The fact is that in reality, the complexity that we observe is not like an increase on a particular axis, but is rather more like the introduction of a new one.
Animals are to plants as a two dimensional graph is to a line. Mind enters into the picture.
Human beings are analogous to adding a “z” axis to the “x-y” of animals.
As to “randomness”, I wonder how they determined the sort of code, to be used to derive such a process. Again, is this applicable to the “randomness” that may occur in nature.
Consider that randomness requires an underlying order: two dice, tossed randomly, will only produce numbers from 2 to 12.
Let’s say someone is doing a drug study.
Generally 40% of people will respond to placebo. There are reason’s for that number, although it is “random”.
An antidepressant for example is considered to be effective if one gets a 60% response.
The factors involved in depression and its improvement are considered to be the same in both groups, so the increase with meds is considered significant.
As far as we know scientifically, the randomness we see in nature, could include the will of God.
It is a factor that cannot be isolated, but would be like the factors that underlie a steady 40% response to placebo.
