Granville Sewell; Still Getting it Wrong.

I see from this post on Uncommon Descent that Granville Sewell still thinks the Second Law of Thermodynamics is necessarily contradicted by evolution. He still fails to see that thermodynamic “disorder” is a measure of “statistical weight” (denoted by Z) and does not strongly entail the patterned “irregularity” such as we see generated by random sources. As such an increase in the statistical weight of a system is an insufficient mathematical index to eliminate the evolutionary development of the complex ordered structures we call life; for it is conceivable that the declared/ordained constraints on physical systems are sufficient to create a bottle neck in the value of Z(t) at some time t giving the states containing living structures a disproportionately large representation and accordingly a realistic probability at t. Sewell would do better to try and wrap his mind round the function Z(t) to see whether or not evolution has a realistic chance. I have discussed this matter several times before on this blog.

This is not to say that the engine of evolutionary change as currently understood actually works. In fact as I have said before I have intuitive doubts about the current understanding of evolution; it’s just that Granville Sewell is repeatedly challenging conventional evolution with a duff argument.


You can't win can you?
